FEATURES/BENEFITS
Every compact one-piece unit arrives fully assembled,
charged, tested, and ready to run.
GAS HEAT MODELS — All ignition components are contained
in the compact IGC (integrated gas controller) which is easily
accessible for servicing. The IGC control board, designed and
manufactured exclusively for Bryant rooftop units, provides
built-in diagnostic capability. An LED (light-emitting diode) sim-
plifies troubleshooting by providing visual fault notification and
required system status confirmation.
The IGC also contains an exclusive anti-cycle protection for
gas heat operation. After 4 continuous cycles on the unit high-
temperature limit switch, the gas heat operation is disabled,
and an error code is issued. This feature greatly improves reli-
ability of the rooftop unit.
The IGC also contains burner control logic for accurate and
dependable gas ignition. The LED is visible without removing
the unit control box access panel. This LED fault-notification
system reduces service person troubleshooting time and mini-
mizes service costs. The IGC also maximizes heating effi-
ciency by controlling evaporator-fan on and off delays.
Tubular, dimpled gas heat exchangers optimize heat transfer
for improved efficiency. The tubular design permits hot gases
to make multiple passes across the path of the supply air. The
dimpled design creates a turbulent gas flow to maximize heat-
ing efficiency.

FEATURES/BENEFITS (cont)
The efficient in-shot burners and all ignition components are
contained in an easily removable, compact assembly.
The California Air Quality Management Districts NOx require-
ment of 40 nanograms/joule or less is met on 036-060 size Low
NOx models.
The extra thick Alumagard™ heat exchanger coating provides
corrosion resistance and ensures long life (optional stainless
steel heat exchangers are available).
The unsightly appearance of flue stacks is eliminated and the
effects of wind on heating operations are diminished by the
induced draft combustion system. The inducer fan draws hot
combustion gas through the heat exchanger at the optimum
rate for the most effective heat transfer. The heat exchanger
operates under negative pressure, preventing flue gas leakage
into the indoor supply air.
During the heating mode, the evaporator-fan relay automati-
cally starts the evaporator fan after the heat exchanger warms
up to a suitable temperature. The 30-second fan delay prevents
cold air from entering the supply duct system when the condi-
tioned space is calling for heat to maximize efficiency.
The direct-spark ignition system saves operating expense when
compared to pilot ignition systems. No crossover tube is
required, therefore no sooting or pilot fouling problems can
occur.
All standard units are designed for natural gas, but an acces-
sory propane conversion kit is available.
All units have a flame rectification sensor to quickly sense the
burner flame and ignite burners almost immediately. Fast shut-
down is a certainty since the sensor reacts quickly to any flame
outage or system failure. In the event of a shutdown, an error
code is issued at the IGC board.
Safety is also assured due to the heating safety controls which
will shut down the unit if there is a problem. If excessive temper-
atures develop, limit switches shut off the gas valve. After
4 continuous short cycles of the high-temperature limit switch,
the IGC board locks out the gas heat cycle to prevent any fur-
ther short cycles. This safety feature is provided exclusively on
Bryant rooftop units. The rollout switch also deenergizes the
gas valve in the event of a flame rollout.
QUIET, EFFICIENT OPERATION AND DEPENDABLE PER-
FORMANCE — Compressors have vibration isolators for quiet
operation. Efficient fan and motor design permits operation at
low sound levels.
Unit sizes 090-300 offer lower utility costs through part-load
operation using 2 or 3 stages of cooling.
Quiet and efficient operation is provided by belt-driven evapora-
tor fans (standard on all units over 5 tons). The belt-driven
evaporator-fan is equipped with variable-pitch pulleys which
allow adjustment within the rpm ranges of the factory-supplied
pulleys.
Increased operating efficiency is achieved through computer-
designed coils featuring staggered internally enhanced copper
tubes. Fins are ripple-edged for strength, lanced, and double
waved for higher heat transfer.
DURABLE, DEPENDABLE CONSTRUCTION — Designed for
durability in any climate, the weather-resistant cabinets are con-
structed of galvanized steel and bonderized, and all exterior
panels are coated with a prepainted baked enamel finish. The
paint finish is non-chalking, and is capable of withstanding
ASTM (American Society for Testing and Materials) B117
500-hour Salt Spray Test. All internal cabinet panels are primed,
permitting longer life and a more attractive appearance for the
entire unit.
In addition, all size 024-151 units are designed with a single,
continuous top piece to eliminate any possible leaks at seams
or gasketing. Totally enclosed condenser-fan motors and
permanently lubricated bearings provide additional unit depend-
ability.

FEATURES/BENEFITS (cont)
EASY INSTALLATION AND CONVERSION
All Units are Shipped in the Vertical Duct Configuration for
fit-up to standard roof curbs. The contractor can order and
install the roof curb early in the construction stage, before deci-
sions on size requirements are made.
All units feature a base rail design with forklift slots and rigging
holes for easier maneuvering. Durable packaging protects all
units during shipment and storage.
The units can be easily converted from a vertical to a horizontal
duct configuration by relocating the panels supplied with the
unit (size 024-150 only).
To Convert 024-151 Units from vertical to horizontal discharge,
simply relocate 2 panels. The same basic unit can be used for a
variety of applications and can be quickly modified at the job-
site.
To Convert 155-300 Units from vertical to horizontal discharge,
use the optional horizontal supply/return adapter roof curb
(581A155,180 and 579F/580F180-300) or accessory conversion
kit (581A210-300). Please note that 581A210-300 units are
available from the factory configured for horizontal supply/return.
Convenient Duct Openings in the unit basepans permit side-
by-side or concentric duct connections (see Application data
section) without requiring internal unit modification.
NOTE: On units using horizontal supply and return, the acces-
sory barometric relief or power exhaust MUST be installed on
the return ductwork.
Thru-The-Bottom Service Connection Capability comes
standard with the rooftop unit to allow power and control wiring
and gas connections to be routed through the unit’s basepan,
thereby minimizing roof penetrations (to prevent water leaks).
(Thru-the-bottom gas connection requires thru-the-bottom
accessory kit.) Power, gas and control connections are made
on the same side of the unit to simplify installation.
The Non-Corrosive Sloped Condensate Drain Pan
(Size 024-150) permits either an external horizontal side con-
densate drain (outside the roof curb) or an internal vertical
bottom drain (inside the roof curb). Both options require an
external, field-supplied P-trap.
Standard 2-in. Throwaway Filters are easily accessed
through a removable panel located above the air intake hood.
No tools are required to change unit filters.
Belt-Driven Evaporator-Fan Motors (optional on 580F units
under 6 tons) allow maximum on-site flexibility without changing
motors or drives.
Low Voltage Wiring Connections are easily made thanks to
the large terminal board which is located for quick, convenient
access.
In addition, color-coded wires permit easy tracing and
diagnostics.
PROVEN COMPRESSOR RELIABILITY — Design techniques
feature computer-programmed balance between compressor,
condenser, and evaporator. Bryant-specified hermetic compres-
sors are equipped with compressor overcurrent and overtem-
perature protection to ensure dependability.
All units have Bryant’s exclusive Acutrol™ (024-151) or TXV
(thermostatic expansion valve) metering device (155-300)
which precisely controls refrigerant flow, preventing slugging
and flood-back, while maintaining optimum unit performance.
Refrigerant filter driers are standard.
INTEGRATED ECONOMIZERS AND OUTDOOR-AIR DAMP-
ERS — Available as options or accessories, economizers and
manual outdoor-air dampers introduce outdoor air which mixes
with the conditioned air, improving indoor-air quality and often
reducing energy consumption.
During a first stage call for cooling, if the outdoor-air tempera-
ture is below the economizer control changeover set point, the
mixed-air sensor modulates the economizer outdoor-air damper
open to take advantage of free cooling provided by the outside
air. When second-stage cooling is called for, the compressor is
energized in addition to the economizer. If the outdoor-air tem-
perature is above the changeover set point, the first stage of
compression is activated and the economizer damper stays at
minimum position.
Accessory upgrade kits allow for control by differential dry-bulb
temperature (outdoor vs return), outdoor air enthalpy
changeover, or more precise differential enthalpy control.
Units can be equipped with different economizer options to
meet specific controls applications. The factory-installed or
field-installed EconoMi$er IV and EconoMi$er2 are available.
The EconoMi$er IV is used with the standard rooftop unit con-
trols and includes an industry standard, stand-alone, solid-state
controller. The control can be used with a CO2 sensor for DCV
(demand control ventilation) operation. For direct digital control
(DDC) applications, the EconoMi$er2 can be operated using a
third party control system. The EconoMi$er2 includes 4 to
20 mA actuator capability for demand control ventilation
applications.
All economizers incorporate a parallel blade, gear-driven
damper system for efficient air mixing and reliable control. In
addition, the standard damper actuator includes a spring return
to provide reliable closure on power loss. The economizers for
sizes 024-151 are equipped with up to 100% barometric relief
capability for high outdoor airflow operations. Economizers for
unit sizes 024-151 are available, factory-installed, for vertical
return only. Economizers for unit sizes 155-300 are compatible
for vertical or horizontal return. An optional field-installed baro-
metric relief package is available for size 155-300 units.
In addition, single-stage power exhaust is available as a field-
installed accessory for EconoMi$er IV to help maintain proper
building pressure.
For units without economizer, year-round ventilation is
enhanced by an optional manual outdoor-air damper. On 024-
150 units, a 25% or 50% manual damper is available as a field-
installed accessory. Unit sizes 155-300 are equipped with a
manual 25% damper.
SERVICE OPTIONS (581B and 581A Units Only) — Servicing
a rooftop unit has never been easier with the factory-installed
service options for these rooftop units. These options include
the following:
• Hinged access panels are provided for the filter/indoor-fan
motor, compressors, evaporator fan, and control box areas.
Quick access to major components is accomplished by simply
unlatching and swinging open the various panels. Each
hinged panel is permanently mounted to the unit, thereby
eliminating the concern of a dropped or wind-blown panel
puncturing delicate roof materials. The 4 extended access
panels are also equipped with ‘‘tie back’’ retaining devices to
hold the door in the open position while servicing the unit.
• An external, covered, 115-v Ground Fault Interrupt (GFI)
receptacle is provided as a convenient power source for drills,
lights, refrigerant recovery units, or other electrical service
tools. A factory-supplied step down transformer is connected
to the “load” side of the unit main power connection (size 024-
150). For sizes 155-300, connect the outlet to a field-supplied
and properly fused branch circuit power supply.
• Slide out “motor-drive-blower” reduces service time (only on
581A210-300).
• An integral non-fused disconnect switch within the rooftop unit
reduces installation time, labor and material costs. Safety is
assured by an interlock which prevents access to the control
box unless the switch is in the OFF position. In addition, the
externally mounted handle incorporates power lockout capa-
bility to further protect service personnel.

FEATURES/BENEFITS (cont)
INDOOR-AIR QUALITY (IAQ) BEGINS WITH BRYANT ROOF-
TOPS — Sloped condensate pans minimize biological growth in
rooftop units in accordance with ASHRAE (American Society of
Heating, Refrigeration and Air Conditioning Engineers)
Standard 62. Two-inch filters with optional dirty filter indicator
switch provide for greater particle reduction in the return air.
The face-split evaporator coils improve the dehumidification
capability of standard units, maximize building humidity control.
Optional proportional reacting CO2 sensor is available with the
EconoMi$er IV outdoor air damper option/accessory to aid the
IAQ benefits.
PERFECT HUMIDITY™ ADAPTIVE DEHUMIDIFICATION
SYSTEM (581C036-060 and 581B036-150 only) — Bryant’s
Perfect Humidity adaptive dehumidification system is an all-
inclusive factory-installed option that can be ordered with any
581B rooftop unit to meet the demand for providing a flexible
and high performing solution to accommodate all of these
design related issues. This system expands the envelope of
operation of 581B rooftop products to provide unprecedented
flexibility to meet year-round comfort conditions. The Perfect
Humidity adaptive dehumidification system has the industry’s
only dual dehumidification mode setting. The Perfect Humidity
system includes two new modes of operation. The 581B and
581C rooftop coupled with the Perfect Humidity system is capa-
ble of operating in normal design cooling mode, subcooling
mode, and hot gas reheat mode. Normal Design Cooling mode
is when the unit will operate under its normal sequence of oper-
ation by cycling compressors to maintain comfort conditions.
Subcooling mode will operate to satisfy part load type condi-
tions when the space requires combined sensible and a higher
proportion of latent load control. Hot Gas Reheat mode will
operate when outdoor temperatures diminish and the need for
latent capacity is required for sole humidity control. Hot Gas
Reheat mode will provide neutral air for maximum dehumidifica-
tion operation.
EXCLUSIVE HOT GAS REHEAT DEHUMIDIFICATION PACK-
AGE (581A181-300) — The hot gas reheat dehumidification
package is a result of recent advances by Bryant in controlling
comfort levels. This factory-installed option significantly
improves the dehumidification capability of the rooftop unit and
helps control humidity levels in the building.
This option provides increased dehumidification by cooling the
hot liquid refrigerant leaving the condenser coil. The hot gas
reheat package consists of a subcooling coil located on the
leaving-air side of the evaporator coil. The location of this coil in
the indoor airstream enhances the latent capacity of the units
by as much as 40%. Many buildings suffer from humidity dam-
age or poor indoor air quality due to humid conditions. The
improved latent capacity provided by the hot gas reheat option
reduces the building’s humidity, eliminating potential property
damage and making the space more comfortable.
The hot gas reheat option is the ideal IAQ option for hot and
humid regions. The operation of the hot gas reheat package
can be controlled by a field-installed, wall mounted humidistat
or Thermidistat™ device. The circuit activates only when
needed (using the accessory humidistat) as opposed to some
dehumidification systems that operate continuously. The humi-
distat can be set for any humidity level between 20% and 80%
relative humidity. The Thermidistat device can be set for any
humidity level between 50% and 90% relative humidity.

Roof Curbs (Horizontal and Vertical) permit installation and
securing of ductwork to curb prior to mounting unit on the curb.
Both 14-in. and 24-in. roof curbs are available as field-installed
accessories.
EconoMi$er IV is available as a factory-installed option in
vertical supply/return configuration only for unit sizes 036-151.
Vertical or horizontal configuration is available for unit sizes
155-300. (The EconoMi$er IV is available as a field-installed
accessory for horizontal and/or vertical supply return configura-
tions.) The EconoMi$er IV is provided with an industry stan-
dard, stand-alone, solid-state controller that is easy to configure
and troubleshoot. The EconoMi$er IV is compatible with non-
DDC applications. The EconoMi$er IV is equipped with a
barometric relief damper capable of relieving up to 100% return
air (for unit sizes 036-151 only). Dry bulb outdoor-air tempera-
ture sensor is provided as standard. The return air sensor,
indoor enthalpy sensor, and outdoor enthalpy sensor are pro-
vided as field-installed accessories to provide enthalpy control,
differential enthalpy control, and differential dry bulb tempera-
ture control.
EconoMi$er IV on 579F and 581A units is used for both vertical
and horizontal return air configurations.
EconoMi$er2 is available as a blanket quote control or as a
field-installed accessory for horizontal and/or vertical supply
return configurations. The EconoMi$er2 is provided without a
controller for use with field-installed third-party controls. The
EconoMi$er2 is equipped with a barometric relief damper capa-
ble of relieving up to 100% return air. Dry bulb outdoor-air tem-
perature sensor is provided as standard. The enthalpy,
differential temperature (adjustable), and differential enthalpy
control are provided as field-installed accessories. The
EconoMi$er2 is capable of control from a 4 to 20 mA signal
through optional 4 to 20 mA design without microprocessor
control (required for third party control interface).
Manual Outdoor-Air Damper can be preset to admit up to 50%
outdoor air for year round ventilation and is available as a field-
installed accessory.
Two-Position Damper package is available as an accessory.
Both 25% or 100% outdoor air dampers are available.
Head Pressure Control (Motormaster) accessory package
maintains condensing temperature between 90 F and 110 F at
outdoor ambient temperatures down to –20 F by condenser-fan
speed modulation or condenser-fan cycling and wind baffles.
Unit-Mounted, Non-Fused Disconnect Switch provides unit
power shutoff. The switch is accessible from outside the unit,
provides power off lockout capability and is available as a
factory-installed option.
Convenience Outlet is factory-installed and internally mounted
with easily accessible 115-v female receptacle.
Compressor Cycle Delay (Time Guard II) accessory prevents
unit from restarting for minimum of 5 minutes after shutdown.
Thru-The-Bottom Utility Connectors permit electrical connec-
tions to be brought to the unit through the basepan. Con-
nectors are available as field-installed accessories.
Fan/Filter Status Switch accessory provides status of indoor
(evaporator) fan (ON/OFF) or filter (CLEAN/DIRTY).
Power Exhaust accessory will provide system exhaust of up to
100% of return air (vertical only). The power exhaust is a field-
installed accessory (separate vertical and horizontal design).
Ultraviolet Germicidal Lamps eliminate odor causing mold
and fungus that may develop in the wet area of the evaporator
section of the unit. The high output, low temperature germicidal
lamps are field installed in the evaporator section of the unit,
aimed at the evaporator coil and condensate pan.
Hinged Panel Option provides hinged access panels for the fil-
ter, compressor, evaporator fan, and control box areas. Filter
hinged panels permit tool-less entry for changing filters. Each
hinged panel is permanently attached to the rooftop unit.
Hinged panels are a factory-installed option.

required.
edb — Entering dry-bulb
ewb — Entering wet-bulb
II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Cooling Capacities table for 580F060 (page 33) at
condenser entering temperature 95 F, evaporator air
entering at 2,000 cfm and 67 F wb. The 580F060 unit will
provide a total cooling capacity of 60,900 Btuh and a sen-
sible heating capacity of 45,300 Btuh. For air entering
evaporator at temperatures other than 80 F edb, calculate
sensible heat capacity correction as required using the for-
mula in the notes following the Cooling Capacities tables.
NOTE: Unit ratings are gross capacities and do not
include the effect of evaporator-fan motor heat. To calcu-
late net capacities, see Step V.
III SELECT HEATING CAPACITY OF UNIT TO PROVIDE
DESIGN CONDITION REQUIREMENTS.
In the Heating Capacities and Efficiencies table (page 9)
note that the 580F060 074 will provide an output capacity
of 59,200 Btuh, which is adequate for the given
application.
IV DETERMINE FAN SPEED AND POWER REQUIRE-
MENTS AT DESIGN CONDITIONS.
Before entering the Fan Performance tables, calculate the
total static pressure required based on unit components.
From the given and the Accessory/FIOP Static Pressure
table on page 75 find:
External static pressure 0.60 in. wg
EconoMi$er IV static pressure 0.12 in. wg
Total Static 0.72 in. wg
Enter the standard motor Fan Performance table 580F060
Vertical Discharge (page 39) at 2,000 cfm and 0.72 in. wg
external static pressure. The standard motor cannot
provide 0.87 in. wg external static pressure. Enter the
alternate motor Fan Performance table for 580F060, verti-
cal discharge. At 2,000 cfm and 0.72 in. wg external static
pressure, find that the rpm is 1219, the Bhp is 1.31, and
the watts are 1168 (interpolation required).
V DETERMINE NET COOLING CAPACITY.
Cooling capacities are gross capacities and do not include
indoor (evaporator) fan motor (IFM) heat. Use the watts
input power to the motor calculated in Section IV above.
IFM Watts = 1168
Determine net cooling capacity using the following
formula:
The calculations show that a 580F060 unit with the alter-
nate motor and drive is the correct selection for the given
conditions.
Net capacity = Gross capacity – IFM heat
)
= 60,900 Btuh – 1168 Watts
(3.412 Btuh
Watts
= 60,900 Btuh – 3985 Btuh
= 56,915 Btuh
Net sensible capacity = 45,300 Btuh – 3985 Btuh
= 41,315 Btuh

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
Where: hewb = Enthalpy of air entering evaporator coil.
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.
Interpolation is permissible.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
Where: hewb = Enthalpy of air entering evaporator coil.
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.
Interpolation is permissible.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

PERFORMANCE DATA (cont)
GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Values include losses for filters, unit casing, and wet coils. See this
page for accessory/FIOP static pressure information.
2. Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using fan
motors up to the wattage ratings shown will not result in nuisance
tripping or premature motor failure. Unit warranty will not be
affected. See Evaporator-Fan Motor Performance table on page 79
for additional information.
3. Use of a field-supplied motor may affect wire sizing. Contact your
Bryant representative for details.
4. Interpolation is permissible. Do not extrapolate. (Belt drive units
only.)
OUTDOOR SOUND POWER (Total Unit)
NOTE: Indoor sound power is available in Bryant’s Electronic Catalog program (ECAT) for specific operating parameters.

†Orifices available through your local Bryant distributor.
ALTITUDE DERATING FACTOR*
*Derating of the unit is not required unless the heating value of the gas exceeds the val-
ues listed in the table above, or if the elevation exceeds 6000 ft. Derating conditions
must be 4% per thousand ft above 2000 ft. For example, at 4000 ft, if the heating value
of the gas exceeds 1000 Btu/ft3, the unit will require a 16% derating. For elevations
above 6000 ft, the same formula applies. For example, at 7000 ft, the unit will require a
28% derating of the maximum heating value per the National Fuel Gas Code.
IMPORTANT: Local utility companies may be reducing heat content of gas at altitudes
above 2000 ft. If this is being done, changing spuds may not be required.

ELECTRICAL DATA

*Used to determine minimum disconnect per NEC.
†Fuse or HACR circuit breaker.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or
HACR breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use
the following formula to determine the percent of voltage imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
= 457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local
electric utility company immediately.
3. For units with power exhaust: If a single power source is to be used, size wire to include
power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered
through the unit (must be in accordance with NEC and/or local codes). Determine the new
MCA including the power exhaust using the following formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 580F060 unit with MCA = 28.9 and MOCP = 35, with
CRPWREXH030A01 power exhaust.
MCA New = 28.9 amps + 1.6 amps = 30.5 amps
If the new MCA does not exceed the published MOCP, then MOCP would not change. The
MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is
acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next
larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

ELECTRICAL DATA (cont)
LEGEND
*Used to determine minimum disconnect per NEC.
†Fuse or HACR circuit breaker.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or
HACR breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use
the following formula to determine the percent of voltage imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
= 457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local
electric utility company immediately.
3. For units with power exhaust: If a single power source is to be used, size wire to include
power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered
through the unit (must be in accordance with NEC and/or local codes). Determine the new
MCA including the power exhaust using the following formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 580F060 unit with MCA = 28.9 and MOCP = 35, with
CRPWREXH030A01 power exhaust.
MCA New = 28.9 amps + 1.6 amps = 30.5 amps
If the new MCA does not exceed the published MOCP, then MOCP would not change. The
MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is
acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next
larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

SELECTION PROCEDURE (With 581B048 Example)
I DETERMINE COOLING AND HEATING REQUIRE-
MENTS AT DESIGN CONDITIONS.
Given:
Required Cooling Capacity (TC) . . . . . . . . . . 44,600 Btuh
Sensible Heat Capacity (SHC). . . . . . . . . . . . 32,000 Btuh
Required Heating Capacity . . . . . . . . . . . . . . 85,000 Btuh
Condenser Entering-Air Temperature . . . . . . . . . . . . 95 F
Evaporator Entering-Air Temperature . . . . . . . . 82 F edb,
67 F ewb
Evaporator Air Quantity . . . . . . . . . . . . . . . . . . . .1600 cfm
External Static Pressure (ESP) . . . . . . . . . . . . 0.75 in. wg
Electrical Characteristics (V-Ph-Hz). . . . . . . . . . . 230-1-60
II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter the Cooling Capacities table (page 92) at condenser
entering temperature of 95 F, evaporator-air entering at
1600 cfm and 80 F db and 67 F wb. The 581B--048115
unit will provide cooling capacity of 48,900 Btuh and a
sensible heat capacity of 34,700 Btuh. For evaporator-air
temperature other than 80 F edb, calculate sensible heat
capacity correction, as required, using the formula found
in Note 3 following the Cooling Capacities tables.
For this example:
Correction factor = 1.10 x (1 – .21) x (82 – 80) = 1.738
Multiply the correction factor of 1.738 by 1600 cfm (a total
of 2781). From the Gross Cooling Capacities tables find
that the sensible heat capacity at 80 F is 34.7 MBtuh
(equivalent to 34,700 Btuh). Add 34,700 and 2781 to get
the corrected sensible heat capacity of 37,481.
NOTE: Unit ratings are gross capacities and do not
include the effect of evaporator-fan motor heat. To calcu-
late net capacities, see Step V.
III SELECT HEATING CAPACITY OF UNIT TO PROVIDE
DESIGN CONDITION REQUIREMENTS.
In the Heating Capacities and Efficiencies table (page 10)
note that unit 581B--048115 will provide output capacity of
93,150 Btuh, which is adequate for the given application.
IV DETERMINE FAN SPEED AND POWER REQUIRE-
MENTS AT DESIGN CONDITIONS.
Before entering the Fan Performance tables, calculate the
total static pressure required based on unit components.
From the given and the Pressure Drop tables (page 133),
find:
External static pressure .75 in. wg
Total static pressure = .75 in. wg
Enter the Fan Performance table for 581B--048115 verti-
cal discharge unit on page 104. At 1600 cfm and 0.75 in.
wg interpolation is required. The rpm is 1051. The bhp is
0.90. The watts are 897. The factory-installed standard
motor and drive are sufficient for operation.
V DETERMINE NET COOLING CAPACITY.
Cooling capacities are gross and do not include indoor-fan
motor (IFM) heat. Determine net capacity using the follow-
ing formula:
Net capacity = gross capacity – IFM heat
= 48,900 Btuh – 897 Watts
(3.413 Btuh )
Watts
= 48,900 Btuh – 3061 Btuh
Net capacity = 45,839 Btuh
Net sensible capacity = 37,481 Btuh – 3061 Btuh
= 34,420 Btuh

*Negative SHC value indicates that the air entering the coil is being
heated.
NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
Where: hewb = Enthalpy of air entering evaporator coil.
3. The SHC is based on 80 F edb temperature of air entering evapo-
rator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Static pressure losses (i.e., EconoMi$er IV) must be added to
external static pressure before entering Fan Performance table.
2. Interpolation is permissible. Do not extrapolate.
3. Fan performance is based on wet coils, clean filters, and casing
losses. See Accessory/FIOP Static Pressure table on page 133.
4. Extensive motor and drive testing on these units ensures that the
full horsepower and watts range of the motor can be utilized with
confidence. Using the fan motors up to the watts or bhp rating
shown will not result in nuisance tripping or premature motor fail-
ure. Unit warranty will not be affected.
5. Use of a field-supplied motor may affect wire size. Contact your
Bryant representative for details.

PERFORMANCE DATA (cont)
FAN RPM AT MOTOR PULLEY SETTING WITH STANDARD MOTOR* — 581B036-150
*Approximate fan rpm shown (standard motor/drive).
FAN RPM AT MOTOR PULLEY SETTING WITH HIGH-STATIC MOTOR* — 581B036-150
*Approximate fan rpm shown (high-static motor/drive).
ALTITUDE COMPENSATION* — 581B036-072
*As the height above sea level increases, there is less oxygen per cubic
foot of air. Therefore, the input rate should be reduced at higher altitudes.
†Orifices are available through your local Bryant distributor.
ALTITUDE COMPENSATION* — 581B090-150
*As the height above sea level increases, there is less oxygen per cubic
foot of air. Therefore, the input rate should be reduced at higher altitudes.
†Orifices are available through your local Bryant distributor.
ALTITUDE DERATING FACTOR*
*Derating of the unit is not required unless the heating value of the gas
exceeds the values listed in the table above, or if the elevation exceeds
6000 ft. Derating conditions must be 4% per thousand ft above 2000 ft.
For example, at 4000 ft, if the heating value of the gas exceeds 1000 Btu/
ft3, the unit will require a 16% derating. For elevations above 6000 ft, the
same formula applies. For example, at 7000 ft, the unit will require a 28%
derating of the maximum heating value per the National Fuel Gas Code.
IMPORTANT: Local utility companies may be reducing heat content of gas
at altitudes above 2000 ft. If this is being done, changing spuds may not be
required.

LEGEND NOTE: The indoor sound power is available in Bryant’s Electronic Catalog
program (ECAT) for specific operating parameters.
EVAPORATOR-FAN MOTOR EFFICIENCY
*Single phase/3 phase.
NOTES:
1. Convert bhp to watts using the following formula:
2. The EPACT (Energy Policy Act of 1992) regulates energy requirements
for specific types of indoor fan motors. Motors regulated by EPACT
include any general purpose, T-frame (three-digit, 143 and larger),
single-speed, foot mounted, polyphase, squirrel cage induction motors
of NEMA (National Electrical Manufacturers Association) design A and
B, manufactured for use in the United States. Ranging from 1 to 200
Hp, these continuous-duty motors operate on 230 and 460 volt, 60 Hz
power. If a motor does not fit into these specifications, the motor does
not have to be replaced by an EPACT-compliant energy-efficient motor.
Variable-speed motors are exempt from EPACT compliance require-
ments. Therefore, the indoor fan motors for Bryant 581B036-150 units
are exempt from these requirements.
ACCESSORY/FIOP STATIC PRESSURE* (in. wg) — 581B036-072
LEGEND *The static pressure must be added to external static pressure. The sum and the
evaporator entering-air cfm should be used in conjunction with the Fan Perfor-
mance tables to determine indoor blower rpm and watts.

ELECTRICAL DATA (cont)
581B036-150 UNITS
LEGEND
*The values listed in this table do not include power exhaust. See table at right for power
exhaust requirements.
†Used to determine minimum disconnect per NEC.
**Fuse or HACR circuit breaker.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load equipment
(refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be
fuse or HACR breaker. The UL, Canada units may be fuse or circuit breaker.
2. Electrical data based on 95 F ambient outdoor-air temperature ± 10% voltage.
3. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater than 2%.
Use the following formula to determine the percent of voltage imbalance.
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
This amount of phase imbalance is satisfactory as it is below the maximum allowable
2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local
electric utility company immediately.
POWER EXHAUST ELECTRICAL DATA
N/A — Not Available
*Single or three phase.
NOTE: If a single power source is to be used, size wire to include power exhaust MCA
and MOCP.
Check MCA and MOCP when power exhaust is powered through the unit. Determine the
new MCA including the power exhaust using the following formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 581B060 unit with MCA = 28.9 and MOCP = 35, with
CRPWREXH030A01 power exhaust.
MCA New = 28.9 amps + 1.6 amps = 30.5 amps
If the new MCA does not exceed the published MOCP, then MOCP would not change.
The MOCP in this example is 35 amps and the MCA New is below 35; therefore the
MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP
to the next larger size. For separate power, the MOCP for the power exhaust will be
15 amps per NEC.

that are controlled to 40 nanograms per joule or less.
NOTE: Capacities for stainless steel heat exchanger units (S/R/T) are the
same as standard units (D/E/F).
*Single phase/three phase. Stainless steel models use the same orifices as equiva-
lent standard heat exchangers.
†Indicates automatic reset.
**60,000 and <72,000 Btuh heat input units have 2 burners. 90,000 and 120,000
Btuh heat input units have 3 burners. 115,000 Btuh heat input units and 150,000
Btuh Heat input units have 3 burners.
†† An LP kit is available as an accessory. If an LP kit is used with Low NOx units, the
Low NOx baffle must be removed and the units will no longer be classified as Low
NOx units.

NOTES:
1. Convert bhp to watts using the following formula:
2. The EPACT (Energy Policy Act of 1992) regulates energy require-
ments for specific types of indoor fan motors. Motors regulated by
EPACT include any general purpose, T-frame (three-digit, 143 and
larger), single-speed, foot mounted, polyphase, squirrel cage
induction motors of NEMA (National Electrical Manufacturers
Association) design A and B, manufactured for use in the United
States. Ranging from 1 to 200 Hp, these continuous-duty motors
operate on 230 and 460 volt, 60 Hz power. If a motor does not fit
into these specifications, the motor does not have to be replaced
by an EPACT-compliant energy-efficient motor. Variable-speed
motors are exempt from EPACT compliance requirements. There-
fore, the indoor fan motors for Bryant 581C024-060 units are
exempt from these requirements.
ACCESSORY/FIOP STATIC PRESSURE* (in. wg) — 581C024-060
LEGEND *The static pressure must be added to external static pressure. The
sum and the evaporator entering-air cfm should be used in conjunction

PERFORMANCE DATA — 581C
ALTITUDE COMPENSATION* — 581C024-060
STANDARD UNIT
*As the height above sea level increases, there is less oxygen per cubic
foot of air. Therefore, heat input rate should be reduced at higher altitudes.
†Orifices available through your Bryant distributor.
ALTITUDE COMPENSATION* — 581C024-060
LOW NOx UNITS
*As the height above sea level increases, there is less oxygen per cubic
foot of air. Therefore, heat input rate should be reduced at higher altitudes.
†Orifices available through your Bryant distributor.
ALTITUDE DERATING FACTOR*
*Derating of the gas heating equipment to compensate for the effects of alti-
tude is always required. Orifice change is not required if the fuel heating
value (at sea level) is below the limits listed in the table at left. Derating con-
ditions must be 4% per thousand ft above 2000 ft. For example, at 4000 ft,
if the heating value of the gas exceeds 1000 Btu/ft3, the unit will require a
16% derating. For elevations above 6000 ft, the same formula applies. For
example, at 7000 ft, the unit will require a 28% derating of the maximum
heating value per the National Fuel Gas Code.

NOTES:
1. In compliance with NEC requirements for multimotor and combination load
equipment (refer to NEC Articles 430 and 440), the overcurrent protective
device for the unit shall be fuse or HACR breaker. The UL, Canada units
may be fuse or circuit breaker.
2. Electrical data based on 95 F ambient outdoor-air temperature ± 10%
voltage.
3. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is
greater than 2%. Use the following formula to determine the percent of volt-
age imbalance.
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
This amount of phase imbalance is satisfactory as it is below the maximum
allowable 2%.

NOTE: If a single power source is to be used, size wire to include power
exhaust MCA and MOCP.
Check MCA and MOCP when power exhaust is powered through the unit.
Determine the new MCA including the power exhaust using the following
formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 581B060—unit with MCA = 28.9 and MOCP = 35, with
CRPWREXH030A01 power exhaust.
MCA New = 28.9 amps + 1.6 amps = 30.5 amps
If the new MCA does not exceed the published MOCP, then MOCP would
not change. The MOCP in this example is 35 amps and the MCA New is
below 35; therefore the MOCP is acceptable. If “MCA New” is larger than
the published MOCP, raise the MOCP to the next larger size. For separate
power, the MOCP for the power exhaust will be 15 amps per NEC.

SELECTION PROCEDURE (With 579F180 Example)
I DETERMINE COOLING AND HEATING REQUIRE-
MENTS AT DESIGN CONDITIONS.
Given:
Required Cooling Capacity . . . . . . . . . . . . . . 170,000 Btuh
Sensible Heat Capacity . . . . . . . . . . . . . . . . 111,000 Btuh
Required Heating Capacity. . . . . . . . . . . . . . 200,000 Btuh
Condenser Entering Air Temp. . . . . . . . . . .95 F (Summer)
Evaporator Entering Air Temp. . . . . . . . . . . . . . . 80 F edb,
67 F ewb
Evaporator Air Quantity . . . . . . . . . . . . . . . . . . .4,500 cfm
External Static Pressure . . . . . . . . . . . . . . . . . . . 0.6 in. wg
Electrical Characteristics (V-Ph-Hz) . . . . . . . . . . 460-3-60
Vertical discharge unit with optional EconoMi$er IV
required.
edb — Entering dry-bulb
ewb — Entering wet-bulb
II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Cooling Capacities table for 579F180300 (page 152)
at condenser entering temperature 95 F, evaporator air
entering at 4,500 cfm and 67 F wb. The 579F180300 unit
will provide a total cooling capacity of 179,000 Btuh and a
sensible heating capacity of 117,000 Btuh. For air entering
evaporator at temperatures other than 80 F edb, calculate
sensible heat capacity correction as required using the for-
mula in the notes following the Cooling Capacities tables.
NOTE: Unit ratings are gross capacities and do not
include the effect of evaporator-fan motor heat. To calcu-
late net capacities, see Step V.
III SELECT HEATING CAPACITY OF UNIT TO PROVIDE
DESIGN CONDITION REQUIREMENTS.
In the ARI Heating Capacities and Efficiencies table
(page 12) note that the 579F180300 will provide an
output capacity of 243,000 Btuh, which is adequate for the
given application.
IV DETERMINE FAN SPEED AND POWER REQUIRE-
MENTS AT DESIGN CONDITIONS.
Before entering the Fan Performance tables, calculate the
total static pressure required based on unit components.
From the given and the Accessory/FIOP Static Pressure
table on page 164 find:
Enter the Fan Performance table 579F180300 (page 161)
at 4,500 cfm and 0.64 in. wg external static pressure. By
interpolation, find that the rpm is 1017 and the watts are
1743.
V DETERMINE NET COOLING CAPACITY.
Cooling capacities are gross capacities and do not include
indoor (evaporator) fan motor (IFM) heat. Use the watts
input power to the motor calculated in Section IV above.
IFM Watts = 1743
Determine net cooling capacity using the following
formula:
Net capacity = Gross capacity – IFM heat
= 179,000 Btuh – 1743 Watts
= 179,000 Btuh – 5947 Btuh
= 173,053 Btuh
Net sensible capacity = 117,000 Btuh – 5947 Btuh
= 111,053 Btuh
The calculations show that a 579F180300 unit with the
standard motor and standard low-medium static drive is
the correct selection for the given conditions.
External static pressure 0.60 in. wg
EconoMi$er IV static pressure 0.04 in. wg
Total static pressure 0.64 in. wg

GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Static pressure losses (i.e., EconoMi$er IV) must be added to external static
pressure before entering Fan Performance table.
2. Interpolation is permissible. Do not extrapolate.
3. Fan performance is based on wet coils, clean filters, and casing losses. See
Accessory/FIOP Static Pressure table on page 193.
4. Extensive motor and drive testing on these units ensures that the full horse-
power and watts range of the motor can be utilized with confidence. Using
fan motors up to the watts or bhp rating shown will not result in nuisance
tripping or premature motor failure. Unit warranty will not be affected.
5. Use of a field-supplied motor may affect wire sizing. Contact your Bryant
representative for details.

*Includes a 4% input reduction per each 1,000 feet.
†Orifices available through your Bryant distributor.
ALTITUDE DERATING FACTOR*
*Derating of the unit is not required unless the heating value of the gas
exceeds the values listed in the table above, or if the elevation
exceeds 6000 ft. Derating conditions must be 4% per thousand ft
above 2000 ft. For example, at 4000 ft, if the heating value of the gas
exceeds 1000 Btu/ft3, the unit will require a 16% derating. For eleva-
tions above 6000 ft, the same formula applies. For example, at 7000 ft,
the unit will require a 28% derating of the maximum heating value per
the National Fuel Gas Code.
IMPORTANT: Local utility companies may be reducing heat content of
gas at altitudes above 2000 ft. If this is being done, then changing
spuds may not be required.

*Fuse or HACR circuit breaker.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load
equipment (refer to NEC Articles 430 and 440), the overcurrent protective
device for the unit shall be fuse or HACR breaker. Canadian units may be
fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is
greater than 2%. Use the following formula to determine the percent voltage
imbalance.
% Voltage Imbalance
EXAMPLE: Supply voltage is 460-3-60.
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent voltage imbalance.
This amount of phase imbalance is satisfactory as it is below the maximum
allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, con-
tact your local electric utility company immediately.

SELECTION PROCEDURE (With 580F240 Example)
I DETERMINE COOLING AND HEATING REQUIRE-
MENTS AT DESIGN CONDITIONS.
Given:
Required Cooling Capacity . . . . . . . . . . . . . . 230,000 Btuh
Sensible Heat Capacity (SHC) . . . . . . . . . . . 170,000 Btuh
Required Heating Capacity. . . . . . . . . . . . . . 215,000 Btuh
Condenser Entering Air Temp. . . . . . . . . . .95 F (Summer)
Evaporator Entering Air Temp. . . . . . . . . . . . . . . 80 F edb,
67 F ewb
Evaporator Air Quantity . . . . . . . . . . . . . . . . . . .8,000 cfm
External Static Pressure . . . . . . . . . . . . . . . . . . . 0.6 in. wg
Electrical Characteristics (V-Ph-Hz) . . . . . . . . . . 460-3-60
Vertical discharge unit with optional EconoMi$er IV
required.
edb — Entering dry-bulb
ewb — Entering wet-bulb
II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Cooling Capacities table for 580F240 (page 183) at
condenser entering temperature 95 F, evaporator air
entering at 8,000 cfm and 67 F wb. The unit will provide a
total cooling capacity of 249,000 Btuh and a sensible heat-
ing capacity (SHC) of 188,000 Btuh. For air entering evap-
orator at temperatures other than 80 F edb, calculate SHC
correction as required.
NOTE: Unit ratings are gross capacities and do not
include the effect of evaporator-fan motor heat. To calcu-
late net capacities, see Step V.
III SELECT HEATING CAPACITY OF UNIT TO PROVIDE
DESIGN CONDITION REQUIREMENTS.
In the ARI Heating Capacities and Efficiencies table note
that the 580F240360 will provide an output capacity of
292,000 Btuh, which is adequate for the given application.
IV DETERMINE FAN SPEED AND POWER REQUIRE-
MENTS AT DESIGN CONDITIONS.
Before entering the Fan Performance tables, calculate the
total static pressure required based on unit components.
From the given and the Accessory/FIOP Static Pressure
table on page 191 find:
External static pressure 0.60 in. wg
EconoMi$er IV static pressure 0.10 in. wg
Total static pressure 0.70 in. wg
Enter the Fan Performance table 580F240360 at
8,000 cfm and 0.70 in. wg external static pressure. By
interpolation, find that the rpm is 1243 and the watts
are 5368.
V DETERMINE NET COOLING CAPACITY.
Cooling capacities are gross capacities and do not include
indoor (evaporator) fan motor (IFM) heat. Use the watts
input power to the motor calculated in Section IV above.
IFM Watts = 5368
Determine net cooling capacity using the following
formula:
Net capacity = Gross capacity – IFM heat
= 249,000 Btuh – 5368 Watts
= 249,000 Btuh – 18,316 Btuh
= 230,684 Btuh
Net sensible capacity = 188,000 Btuh – 18,316 Btuh
= 169,684 Btuh
The calculations show that a 580F240360 unit with the
standard motor and standard low-medium static drive is
the correct selection for the given conditions.

GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Static pressure losses (i.e., EconoMi$er IV) must be added to external static
pressure before entering Fan Performance table.
2. Interpolation is permissible. Do not extrapolate.
3. Fan performance is based on wet coils, clean filters, and casing losses. See
Accessory/FIOP Static Pressure table on page 223.
4. Extensive motor and drive testing on these units ensures that the full horse-
power and watts range of the motor can be utilized with confidence. Using
fan motors up to the watts or bhp rating shown will not result in nuisance
tripping or premature motor failure. Unit warranty will not be affected.
5. Use of a field-supplied motor may affect wire size. Contact your Bryant rep-
resentative for details.

ALTITUDE COMPENSATION* —
580F180-300
*Includes a 4% input reduction per each 1,000 feet.
†Orifices available through your Bryant dealer.
ALTITUDE DERATING FACTOR*
*Derating of the unit is not required unless the heating value of the gas
exceeds the values listed in the table above, or if the elevation
exceeds 6000 ft. Derating conditions must be 4% per thousand ft
above 2000 ft. For example, at 4000 ft, if the heating value of the gas
exceeds 1000 Btu/ft3, the unit will require a 16% derating. For ele-
vations above 6000 ft, the same formula applies. For example, at 7000
ft, the unit will require a 28% derating of the maximum heating value
per the National Fuel Gas Code.
IMPORTANT: Local utility companies may be reducing heat content of
gas at altitudes above 2000 ft. If this is being done, changing spuds
may not be required.

*The static pressure must be added to external static pressure. The sum and the evaporator entering-air cfm should then be
used in conjunction with the Fan Performance tables to determine blower rpm and watts.
FAN RPM AT MOTOR PULLEY SETTINGS*

EVAPORATOR-FAN MOTOR PERFORMANCE
LEGEND
*Extensive motor and electrical testing on these units ensures that the full horse-
power (brake kilowatt) range of the motors can be utilized with confidence. Using
your fan motors up to the horsepower (brake kilowatt) ratings shown in this table
will not result in nuisance tripping or premature motor failure. Unit warranty will

NOTE: All indoor-fan motors 5 hp and larger meet the minimum efficiency require-
ments as established by the Energy Policy Act of 1992 (EPACT) effective
October 24, 1997.
EVAPORATOR-FAN MOTOR EFFICIENCY
NOTE: The EPACT (Energy Policy Act of 1992) regulates energy
requirements for specific types of indoor fan motors. Motors regulated
by EPACT include any general purpose, T-frame (three-digit, 143 and
larger), single-speed, foot mounted, polyphase, squirrel cage induction
motors of NEMA (National Electrical Manufacturers Association) design
A and B, manufactured for use in the United States. Ranging from 1 to
200 Hp, these continuous-duty motors operate on 230 and 460 volt,
60 Hz power. If a motor does not fit into these specifications, the motor
does not have to be replaced by an EPACT-compliant energy-efficient
motor. Variable-speed motors are exempt from EPACT compliance
requirements. Therefore, the indoor-fan motors for these units are
exempt from these requirements.

*Fuse or HACR circuit breaker.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load
equipment (refer to NEC Articles 430 and 440), the overcurrent protective
device for the unit shall be fuse or HACR breaker. Canadian units may be
fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is
greater than 2%. Use the following formula to determine the percent voltage
imbalance.
% Voltage Imbalance
EXAMPLE: Supply voltage is 460-3-60.
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent voltage imbalance.
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum
allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, con-
tact your local electric utility company immediately.

Evaporator Air Quantity . . . . . . . . . . . . . . . . . . .6,000 cfm
External Static Pressure . . . . . . . . . . . . . . . . . . 1.40 in. wg
Electrical Characteristics (V-Ph-Hz) . . . . . . . . . . 230-3-60
II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Cooling Capacities table for 581A180 at condenser
entering temperature of 95 F, evaporator air quantity of
6,000 cfm, and indoor air temperature of 67 F. The
581A180 unit will provide a total cooling capacity of
190,000 Btuh and a SHC of 136,000 Btuh. For evaporator
air temperatures other than 80 F, calculate SHC correction
using formula in notes under cooling capacity tables.
Unit meets design conditions for TC and SHC.
NOTE: Unit ratings are gross capacities and do not
include the effect of indoor fan motor heat. To calculate net
capacities, see Step V.
III SELECT HEATING CAPACITY OF UNIT TO PROVIDE
DESIGN CONDITION REQUIREMENT.
In Heating Capacities and Efficiencies table, note that
581A180275 unit will provide 223,000 Btuh with an input
of 275,000 Btuh.
IV DETERMINE FAN SPEED AND POWER REQUIRE-
MENTS AT DESIGN CONDITIONS.
Before entering the Fan Performance tables, calculate the
total static pressure required based on unit components.
Tabulated fan performance includes filters and wet evapo-
rator coil. Refer to Accessory/FIOP Static Pressure table
for added pressure drops.
Calculate pressure drop:
Design External Static Pressure 1.40
EconoMi$er IV 0.07
1.47 in. wg (ESP)
Enter Fan Performance tables for 581A180 (low heat
units) at 6,000 cfm and 1.47 in. wg. The rpm is 1228 and
the Bhp is 4.73. The factory-installed 5 hp motor and alter-
nate high-static drive are sufficient for this operation.
V DETERMINE NET COOLING CAPACITIES.
Cooling capacities are gross capacities and do not include
indoor (evaporator) fan motor (IFM) heat. To determine
input power to the motor, enter the Fan Performance
tables for 581A180 (low heat units) at 6,000 cfm and
1.47 in. wg. Input watts to the motor are 4035.
Determine net cooling capacity and net sensible cooling
capacity using the following formulas:
IFM Heat = Input Watts x 3.412 Btuh/Watt
= 4035 x 3.412
= 13,767 Btuh
Net Capacity = Gross Capacity – IFM Heat
= 190,000 – 13,767
= 176,233 Btuh
Net Sensible Cap. = Gross Sensible Cap. – IFM Heat
= 136,000 – 13,767
= 122,233 Btuh
The calculations show that a 581A180275 unit is the cor-
rect selection for the given conditions.
VI SELECT THE UNIT THAT CORRESPONDS TO POWER
SOURCE AVAILABLE.
The electrical data table shows that the 230-3-60 unit is
available.

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving evapo-
rator coil (hlwb)
Where: hewb = Enthalpy of air entering evaporator coil
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.
Interpolation is permissible.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving evapo-
rator coil (hlwb)
Where: hewb = Enthalpy of air entering evaporator coil
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.
Interpolation is permissible.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

*Standard low-medium static drive range is 873 to 1021 rpm. Alternate
high-static drive range is 1025 to 1200. Other rpms require a field-
supplied drive.
Refer to page 262 for general Fan Performance Data notes.
NOTES:
1. Maximum continuous bhp for the standard motor is 6.13. The max-
imum continuous watts is 5180. Do not adjust motor rpm such that
motor maximum bhp and/or watts is exceeded at the maximum
operating cfm. See Evaporator Fan Motor Data tables for more
information.
2. Fan performance is identical for horizontal discharge applications
using Bryant horizontal adapter curb.

GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Static pressure losses (i.e., EconoMi$er IV) must be added to
external static pressure before entering Fan Performance table.
2. Interpolation is permissible. Do not extrapolate.
3. Fan performance is based on wet coils, clean filters, and casing
losses. See Accessory/FIOP Static Pressure table on page 273.
4. Extensive motor and drive testing on these units ensures that the
full horsepower and watts range of the motor can be utilized with
confidence. Using the fan motors up to the watts or bhp rating
shown will not result in nuisance tripping or premature motor fail-
ure. Unit warranty will not be affected.
5. Use of a field-supplied motor may affect wire size. Contact your
Bryant representative for details.
6. Field-supplied drive requires changing belt and motor pulley to
meet desired airflow. See application data or contact your local
Bryant representative for details.

ALTITUDE DERATING FACTOR*
*Derating of the unit is not required unless the heating value of the gas
exceeds the values listed in the table above, or if the elevation
exceeds 6000 ft. Derating conditions must be 4% per thousand ft
above 2000 ft. For example, at 4000 ft, if the heating value of the gas
exceeds 1000 Btu/ft3, the unit will require a 16% derating. For eleva-
tions above 6000 ft, the same formula applies. For example, at 7000 ft,
the unit will require a 28% derating of the maximum heating value per
the National Fuel Gas Code.
IMPORTANT: Local utility companies may be reducing heat content of
gas at altitudes above 2000 ft. If this is being done, changing spuds
may not be required.

*Fuse or HACR circuit breaker.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load
equipment (refer to NEC Articles 430 and 440), the overcurrent protective
device for the unit shall be fuse or HACR breaker. Canadian units may be
fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is
greater than 2%. Use the following formula to determine the percent of volt-
age imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
= 457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum
allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, con-
tact your local electric utility company immediately.

CONTROLS
OPERATING SEQUENCE, SIZE 024-151 UNITS
Cooling, Units Without Economizer — When thermostat calls
for cooling, terminals G and Y1 are energized. The indoor-fan
contactor (IFC) and compressor contactor are energized
and indoor-fan motor, compressor, and outdoor fan starts. The
outdoor-fan motor runs continuously while unit is cooling.
For units with 2 stages of cooling, if the thermostat calls for a
second stage of cooling by energizing Y2, compressor contac-
tor no. 2 (C2) is energized and compressor no. 2 starts.
Heating, Units Without Economizer — When the thermostat
calls for heating, terminal W1 is energized. To prevent thermo-
stat short-cycling, the unit is locked into the Heating mode for at
least 1 minute when W1 is energized. The induced-draft motor
is energized and the burner ignition sequence begins. The
indoor (evaporator) fan motor (IFM) is energized 45 seconds
after a flame is ignited. On units equipped for two stages of
heat, when additional heat is needed, W2 is energized and the
high-fire solenoid on the main gas valve (MGV) is energized.
When the thermostat is satisfied and W1 is deenergized, the
IFM stops after a 45-second time-off delay.
Cooling, Units With EconoMi$er IV — When free cooling is
not available, the compressors will be controlled by the zone
thermostat. When free cooling is available, the outdoor-air
damper is modulated by the EconoMi$er IV control to provide a
50 to 55 F mixed-air temperature into the zone. As the mixed-air
temperature fluctuates above 55 or below 50 F, the dampers
will be modulated (open or close) to bring the mixed-air temper-
ature back within control.
If mechanical cooling is utilized with free cooling, the outdoor-air
damper will maintain its current position at the time the com-
pressor is started. If the increase in cooling capacity causes the
mixed-air temperature to drop below 45 F, then the outdoor-air
damper position will be decreased to the minimum position. If
the mixed-air temperature continues to fall, the outdoor-air
damper will close. Control returns to normal once the mixed-air
temperature rises above 48 F.
If optional power exhaust is installed, as the outdoor-air damper
opens and closes, the power exhaust fans will be energized
and deenergized.
If field-installed accessory CO2 sensors are connected to the
EconoMi$er IV control, a demand controlled ventilation strategy
will begin to operate. As the CO2 level in the zone increases
above the CO2 set point, the minimum position of the damper
will be increased proportionally. As the CO2 level decreases
because of the increase in fresh air, the outdoor-air damper will
be proportionally closed.
For EconoMi$er IV operation, there must be a thermostat call
for the fan (G). If the unit is occupied and the fan is on, the
damper will operate at minimum position. Otherwise, the
damper will be closed when the thermostat is satisfied.
When the EconoMi$er IV control is in the occupied mode and a
call for cooling exists (Y1 on the thermostat), the control will first
check for indoor fan operation. If the fan is not on, then cooling
will not be activated. If the fan is on, then the control will open
the EconoMi$er IV damper to the minimum position.
On the initial power to the EconoMi$er IV control, it will take the
damper up to 21/2 minutes before it begins to position itself. Any
change in damper position will take up to 30 seconds to initiate.
Damper movement from full closed to full open (or vice versa)
will take between 11/2 and 21/2 minutes.
If free cooling can be used as determined from the appropriate
changeover command (switch, dry bulb, enthalpy curve, differ-
ential dry bulb, or differential enthalpy), then the control will
modulate the dampers open to maintain the mixed-air tempera-
ture set point at 50 to 55 F.
If there is a further demand for cooling (cooling second stage —
Y2 is energized), then the control will bring on compressor
stage 1 to maintain the mixed-air temperature set point. The
EconoMi$er IV damper will be open at maximum position.
EconoMi$er IV operation is limited to a single compressor.
Heating, Units With Economizer
NOTE: The units have 2 stages of heat.
When the thermostat calls for heating, power is sent to W1 on
the IGC (integrated gas unit controller) board. An LED (light-
emitting diode) on the IGC board will be on during normal oper-
ation. A check is made to ensure that the rollout switch and limit
switch are closed and the induced-draft motor is running. The
induced-draft motor is then energized, and when speed is
proven with the hall effect sensor on the motor, the ignition acti-
vation period begins. The burners will ignite within 5 seconds.
If the burners do not light, there is a 22-second delay before
another 5-second attempt. If the burners still do not light, this
sequence is repeated for 15 minutes. After the 15 minutes have
elapsed, if the burners still have not lit, heating is locked out. To
reset the control, break 24-v power to the thermostat.
When ignition occurs the IGC board will continue to monitor the
condition of the rollout and limit switches, the hall effect sensor,
as well as the flame sensor. If the unit is controlled through a
room thermostat set for fan auto., 45 seconds after ignition
occurs, the indoor-fan motor will be energized (and the outdoor-
air dampers will open to their minimum position). If for some
reason the overtemperature limit opens prior to the start of the
indoor fan blower, on the next attempt, the 45-second delay will
be shortened to 5 seconds less than the time from initiation of
heat to when the limit tripped. Gas will not be interrupted to the
burners and heating will continue. Once modified, the fan on
delay will not change back to 45 seconds unless power is reset
to the control.
When additional heat is required, W2 closes and initiates power
to the second stage of the main gas valve. When the thermostat
is satisfied, W1 and W2 open and the gas valve closes, inter-
rupting the flow of gas to the main burners. If the call for W1
lasted less than 1 minute, the heating cycle will not terminate
until 1 minute after W1 became active. If the unit is controlled
through a room thermostat set for fan auto., the indoor-fan
motor will continue to operate for an additional 45 seconds then
stop (and the outdoor-air dampers will close). If the overtemper-
ature limit opens after the indoor motor is stopped within
10 minutes of W1 becoming inactive, on the next cycle the time
will be extended by 15 seconds. The maximum delay is 3 min-
utes. Once modified, the fan off delay will not change back to
45 seconds unless power is reset to the control.
When the thermostat is satisfied and W1 and W2 are deener-
gized, the IFM continues to run and the economizer damper
then moves to the minimum position.

(evaporator) fan contactor (IFC) and compressor contactor
no. 1 (C1) are energized, and evaporator-fan motor (IFM), com-
pressor no. 1 and condenser fan(s) start. The condenser-fan
motor(s) runs continuously while unit is cooling. When the ther-
mostat calls for a second stage of cooling by energizing Y2,
compressor contactor no. 2 (C2) is energized and compressor
no. 2 starts.

is satisfied, W1 and W2 open and the gas valve closes, inter-
rupting the flow of gas to the main burners. If the call for W1

will continue to operate for an additional 45 seconds then stop. If
the overtemperature limit opens after the indoor motor is
stopped within 10 minutes of W1 becoming inactive, on the next
cycle the time will be extended by 15 seconds. The maximum
delay is 3 minutes. Once modified, the fan off delay will not
change back to 45 seconds unless power is reset to the control.
An LED indicator is provided on the IGC to monitor operation.
The IGC is located by removing the side panel and viewing the
IGC through the view port located in the control box access
panel. During normal operation, the LED is continuously on.
Cooling, Units With EconoMi$er IV — When free cooling is
not available, the compressors will be controlled by the zone
thermostat. When free cooling is available, the outdoor-air
damper is modulated by the EconoMi$er IV control to provide a
50 to 55 F mixed-air temperature into the zone. As the mixed-air
temperature fluctuates above 55 or below 50 F, the dampers
will be modulated (open or close) to bring the mixed-air temper-
ature back within control.
If mechanical cooling is utilized with free cooling, the outdoor-air
damper will maintain its current position at the time the com-
pressor is started. If the increase in cooling capacity causes the
mixed-air temperature to drop below 45 F, then the outdoor-air
damper position will be decreased to the minimum position. If
the mixed-air temperature continues to fall, the outdoor-air
damper will close. Control returns to normal once the mixed-air
temperature rises above 48 F.
If optional power exhaust is installed, as the outdoor-air damper
opens and closes, the power exhaust fans will be energized
and deenergized.
If field-installed accessory CO2 sensors are connected to the
EconoMi$er IV control, a demand controlled ventilation strategy
will begin to operate. As the CO2 level in the zone increases
above the CO2 set point, the minimum position of the damper
will be increased proportionally. As the CO2 level decreases
because of the increase in fresh air, the outdoor-air damper will
be proportionally closed.
For EconoMi$er IV operation, there must be a thermostat call
for the fan (G). If the unit is occupied and the fan is on, the
damper will operate at minimum position. Otherwise, the
damper will be closed.
When the EconoMi$er IV control is in the occupied mode and a
call for cooling exists (Y1 on the thermostat), the control will first
check for indoor fan operation. If the fan is not on, then cooling
will not be activated. If the fan is on, then the control will open
the EconoMi$er IV damper to the minimum position.
On the initial power to the EconoMi$er IV control, it will take the
damper up to 21/2 minutes before it begins to position itself. Any
change in damper position will take up to 30 seconds to initiate.
Damper movement from full closed to full open (or vice versa)
will take between 11/2 and 21/2 minutes.
If free cooling can be used as determined from the appropriate
changeover command (switch, dry bulb, enthalpy curve, differ-
ential dry bulb, or differential enthalpy), then the control will
modulate the dampers open to maintain the mixed-air tempera-
ture set point at 50 to 55 F.
If there is a further demand for cooling (cooling second stage —
Y2 is energized), then the control will bring on compressor
stage 1 to maintain the mixed-air temperature set point. The
EconoMi$er IV damper will be open at maximum position.
EconoMi$er IV operation is limited to a single compressor.

Units With Hot Gas Bypass Dehumidification Package —
When thermostat calls for cooling, terminals G and Y1 and Y2
and the compressor contactors C1 and C2 are energized. The
indoor (evaporator) fan motor (IFM), compressor, and outdoor
(condenser) fan motor (OFM) start. The OFM runs continuously
while the unit is in cooling. As shipped from the factory, hot gas
bypass dehumidification circuit is always energized. If hot gas
bypass circuit modulation is desired, a field-installed, wall-
mounted humidistat is required.
If the hot gas bypass humidistat is installed and calls for the hot
gas bypass subcooler coil to operate, the humidistat internal
switch closes. This energizes and closes the liquid line solenoid
valve coil (LLSV) of the hot gas bypass circuit, forcing the hot
liquid refrigerant of the liquid line to enter the subcooler coil. As
the hot liquid passes through the subcooler coil, it is exposed to
the cold supply airflow coming off from the evaporator coil and
the liquid is further cooled to a temperature approaching the
evaporator coil leaving-air temperature. The state of the refrig-
erant leaving the subcooler coil is a highly subcooled liquid
refrigerant. The liquid then enters a thermostatic expansion
valve (TXV) where the liquid is dropped to a lower pressure.
The TXV does not have a pressure drop great enough to
change the liquid to a 2-phase fluid. The TXV can throttle the
pressure drop of the liquid refrigerant and maintain proper con-
ditions at the compressor suction valve over a wide range of
operating conditions. The liquid then enters a second fixed
restrictor expansion device for a second pressure drop to a
2-phase fluid. The liquid proceeds to the evaporator coil at a
temperature lower than normal cooling operation. This lower
temperature is what increases the latent capacity of the rooftop.
The 2-phase refrigerant passes through the evaporator and is
changed into a vapor. The air passing over the evaporator coil
will become colder than during normal operation as a result of
the colder refrigerant temperatures. However, as it passes over
the subcooler coil, the air will be warmed slightly.
As the refrigerant leaves the evaporator, the refrigerant passes
a low-pressure switch in the suction line. This low-pressure
switch will de-activate the hot gas bypass package when the
suction pressure reaches 60 psig. The low-pressure switch is
an added safety device to protect against evaporator coil
freeze-up. The low-pressure switch will only de-activate and
open the liquid line solenoid valve in the hot gas bypass circuit.
The compressors will continue to run as long as there is a call
for cooling, regardless of the position of the low-pressure
switch. The solenoid valve and the hot gas bypass package will
be re-activated only when the call for cooling has been satis-
fied, the low-pressure switch has closed, and a new call for
cooling exists. The crankcase heaters on the scroll compressor
provide additional protection for the compressor due to the
additional refrigerant charge in the subcooler.
When the humidistat is satisfied, the humidistat internal switch
opens cutting power to and opening the LLSV. The refrigerant is
routed back through the evaporator and the subcooler coil is
removed from the refrigerant loop.
When the thermostat is satisfied, C1 and C2 are deenergized
and the compressor and OFM shut off. After a 30-second delay,
the IFM shuts off. If the thermostat fan selector switch is in the
ON position, the IFM will run continuously.
OPERATING SEQUENCE, 581A210-300
Cooling, Units Without Economizer — When thermostat calls
for cooling, terminals G and Y1 are energized. The indoor-fan
contactor (IFC) and compressor contactors A1 and B1 (except
300 units) are energized and indoor-fan motor, compressor, and
outdoor fan starts. The outdoor fan motor runs continuously
while unit is cooling. If further cooling is required, the Y2 output
from the thermostat energizes compressor contactor C1 (B1 on
300 units).
Heating, Units Without Economizer
NOTE: The 581A210-300 units have 2 stages of heat.
When the thermostat calls for heating, power is sent to W on
the IGC (integrated gas unit controller) board. An LED (light-
emitting diode) on the IGC board will be on during normal oper-
ation. A check is made to ensure that the rollout switch and limit
switch are closed and the induced-draft motor is running.
The induced-draft motor is then energized, and when speed is
proven with the hall effect sensor on the motor, the ignition acti-
vation period begins. The burners will ignite within 5 seconds.
If the burners do not light, there is a 22-second delay before
another 5-second attempt. If the burners still do not light, this
sequence is repeated for 15 minutes. After the 15 minutes have
elapsed, if the burners still have not lit, heating is locked out.
To reset the control, break 24-v power to the thermostat. When
ignition occurs the IGC board will continue to monitor the condi-
tion of the rollout and limit switches, the hall effect sensor, as
well as the flame sensor. If the unit is controlled through a room
thermostat set for fan auto., 45 seconds after ignition occurs,
the indoor-fan motor will be energized (and the outdoor-air
dampers will open to their minimum position). If for some rea-
son the overtemperature limit opens prior to the start of the
indoor fan blower, on the next attempt, the 45-second delay will
be shortened to 5 seconds less than the time from initiation of
heat to when the limit tripped. Gas will not be interrupted to the
burners and heating will continue.
Once modified, the fan on delay will not change back to
45 seconds unless power is reset to the control.
When additional heat is required, W2 closes and initiates power
to the second stage of the main gas valve. When the thermostat
is satisfied, W1 and W2 open and the gas valve closes, inter-
rupting the flow of gas to the main burners. If the call for W1
lasted less than 1 minute, the heating cycle will not terminate
until 1 minute after W1 became active. If the unit is controlled
through a room thermostat set for fan auto., the indoor-fan
motor will continue to operate for an additional 45 seconds then
stop (and the outdoor-air dampers will close).
If the overtemperature limit opens after the indoor motor is
stopped within 10 minutes of W1 becoming inactive, on the next
cycle the time will be extended by 15 seconds. The maximum
delay is 3 minutes. Once modified, the fan off delay will not
change back to 45 seconds unless power is reset to the control.
A LED indicator is provided on the IGC to monitor operation.
The IGC is located by removing the side panel and viewing the
IGC through the view port located in the control box access
panel. During normal operation, the LED is continuously on.
Cooling, Units With EconoMi$er IV — When free cooling is
not available, the compressors will be controlled by the zone
thermostat. When free cooling is available, the outdoor-air
damper is modulated by the EconoMi$er IV control to provide a
50 to 55 F mixed-air temperature into the zone. As the mixed-air
temperature fluctuates above 55 or below 50 F, the dampers
will be modulated (open or close) to bring the mixed-air temper-
ature back within control.
If mechanical cooling is utilized with free cooling, the outdoor-air
damper will maintain its current position at the time the com-
pressor is started. If the increase in cooling capacity causes the
mixed-air temperature to drop below 45 F, then the outdoor-air
damper position will be decreased to the minimum position. If
the mixed-air temperature continues to fall, the outdoor-air
damper will close. Control returns to normal once the mixed-air
temperature rises above 48 F.
If optional power exhaust is installed, as the outdoor-air damper
opens and closes, the power exhaust fans will be energized
and deenergized.
292
CONTROLS (cont)
If field-installed accessory CO2 sensors are connected to the
EconoMi$er IV control, a demand controlled ventilation strategy
will begin to operate. As the CO2 level in the zone increases
above the CO2 set point, the minimum position of the damper
will be increased proportionally. As the CO2 level decreases
because of the increase in fresh air, the outdoor-air damper will
be proportionally closed.
For EconoMi$er IV operation, there must be a thermostat call
for the fan (G). If the unit is occupied and the fan is on, the
damper will operate at minimum position. Otherwise, the
damper will be closed.
When the EconoMi$er IV control is in the occupied mode and a
call for cooling exists (Y1 on the thermostat), the control will first
check for indoor fan operation. If the fan is not on, then cooling
will not be activated. If the fan is on, then the control will open
the EconoMi$er IV damper to the minimum position.
On the initial power to the EconoMi$er IV control, it will take the
damper up to 21/2 minutes before it begins to position itself. Any
change in damper position will take up to 30 seconds to initiate.
Damper movement from full closed to full open (or vice versa)
will take between 11/2 and 21/2 minutes.
If free cooling can be used as determined from the appropriate
changeover command (switch, dry bulb, enthalpy curve, differ-
ential dry bulb, or differential enthalpy), then the control will
modulate the dampers open to maintain the mixed-air tempera-
ture set point at 50 to 55 F.
If there is a further demand for cooling (cooling second stage —
Y2 is energized), then the control will bring on compressor
stage 1 to maintain the mixed-air temperature set point. The
EconoMi$er IV damper will be open at maximum position.
EconoMi$er IV operation is limited to a single compressor.
Heating, Units With Economizer
NOTE: The units have 2 stages of heat.
When the thermostat calls for heating, power is sent to W1 on
the IGC (integrated gas unit controller) board. An LED (light-
emitting diode) on the IGC board will be on during normal oper-
ation. A check is made to ensure that the rollout switch and limit
switch are closed and the induced-draft motor is running. The
induced-draft motor is then energized, and when speed is
proven with the hall effect sensor on the motor, the ignition acti-
vation period begins. The burners will ignite within 5 seconds.
If the burners do not light, there is a 22-second delay before
another 5-second attempt. If the burners still do not light, this
sequence is repeated for 15 minutes. After the 15 minutes have
elapsed, if the burners still have not lit, heating is locked out. To
reset the control, break 24-v power to the thermostat.
When ignition occurs the IGC board will continue to monitor the
condition of the rollout and limit switches, the hall effect sensor,
as well as the flame sensor. If the unit is controlled through a
room thermostat set for fan auto., 45 seconds after ignition
occurs, the indoor-fan motor will be energized (and the outdoor-
air dampers will open to their minimum position). If for some
reason the overtemperature limit opens prior to the start of the
indoor fan blower, on the next attempt, the 45-second delay will
be shortened to 5 seconds less than the time from initiation of
heat to when the limit tripped. Gas will not be interrupted to the
burners and heating will continue. Once modified, the fan on
delay will not change back to 45 seconds unless power is reset
to the control.
When additional heat is required, W2 closes and initiates power
to the second stage of the main gas valve. When the thermostat
is satisfied, W1 and W2 open and the gas valve closes, inter-
rupting the flow of gas to the main burners. If the call for W1
lasted less than 1 minute, the heating cycle will not terminate
until 1 minute after W1 became active. If the unit is controlled
through a room thermostat set for fan auto., the indoor-fan
motor will continue to operate for an additional 45 seconds then
stop (and the outdoor-air dampers will close). If the overtemper-
ature limit opens after the indoor motor is stopped within
10 minutes of W1 becoming inactive, on the next cycle the time
will be extended by 15 seconds. The maximum delay is 3 min-
utes. Once modified, the fan off delay will not change back to
45 seconds unless power is reset to the control.
When the thermostat is satisfied and W1 and W2 are deener-
gized, the IFM continues to run and the economizer damper
then moves to the minimum position.

APPLICATION DATA
1. CONDENSATE DRAIN PAN — A sloped condensate drain
pan is supplied on all units. The condensate pan must be
externally trapped. Condensate drains are located on both
the bottom and end of the unit.
2. DUCTWORK — All ductwork must be attached to flanges.
If no flanges are present, they must be field supplied.
Secure vertical discharge ductwork to roof curb. For hori-
zontal discharge applications, attach ductwork to flanges.
Field-supplied flanges can be attached to horizontal dis-
charge openings and all ductwork attached to flanges.
3. THERMOSTAT — Use of 2-stage cooling thermostat is rec-
ommended for all units equipped with economizer. A
2-stage cooling thermostat is required for size 090-300
units with integrated economizer.
4. HEATING-TO-COOLING CHANGEOVER — All units are
automatic changeover from heating to cooling when auto-
matic changeover thermostat and subbase are used.
5. AIRFLOW — Units are draw-thru on cooling and blow-thru
on heating.
6. MAXIMUM AIRFLOW — To minimize possibility of conden-
sate blow-off from evaporator, airflow through units should
not exceed 500 cfm/ton (sizes 024-240) and 11,250 cfm
(size 300).
7. MINIMUM AIRFLOW — Minimum airflow for cooling is
300 cfm/ton (sizes 036-240) and 280 cfm/ton (300 units).
Refer to Heating Capacities and Efficiencies table for mini-
mum heating airflow.
8. MINIMUM AMBIENT OPERATING TEMPERATURE —
Minimum ambient operating temperature for size 036-150
standard units is 25 F. With accessory Motormaster® I, II, or
IV units can operate at outdoor temperatures down to –20 F.
Unit sizes 155-300 are designed to operate at outdoor tem-
peratures down to 40 F. With accessory Motormaster I or
Motormaster V control, units can operate at outdoor tem-
peratures down to –20 F.
NOTE: Under most application circumstances, if the roof-
top unit is equipped with an economizer, low ambient con-
trols are not required. Unless the outdoor air is
unsatisfactory for free cooling due to high temperature,
excessive humidity, or poor air quality, outdoor air should
be used.
9. MAXIMUM OPERATING OUTDOOR-AIR TEMPERA-
TURE — Maximum outdoor operating temperature for
cooling is shown below (60 Hz):
581B,C024-150 125 F
580F036-151 115 F

581A300 125 F
10. HIGH ALTITUDES — These may require a change to the
gas orifice. Refer to Altitude Compensation tables.
11. MINIMUM HEATING ENTERING AIR TEMPERATURE —
The minimum temperature of air entering the dimpled heat
exchanger is 50 F continuous and 45 F intermittent for alu-
minum heat exchangers and 40 F continuous and 35 F
intermittent for stainless steel heat exchangers. To operate
at lower mixed-air temperatures, a field-supplied outdoor-
air thermostat must be used to initiate both stages of heat
when the temperature is below the minimum required tem-
perature to ensure full fire operation. Wire the outdoor-air
thermostat (part no. HH22AG106) in series with the second
stage gas valve as shown below. Set the outdoor-air
thermostat at 35 F for stainless steel heat exchangers or
45 F for aluminum heat exchangers. This temperature set-
ting will bring on the second stage of heat whenever the
ambient temperature is below the thermostat set point.
Indoor comfort may be compromised when heating is initi-
ated using low entering air temperatures with insufficient
heating temperature rise.
12. MOTOR DATA — Due to Bryant’s internal unit design
(draw-thru over the motor), air path, and specially designed
motors, the full horsepower (maximum continuous bhp)
listed in the Physical Data tables and the notes following
each Fan Performance table can be utilized with extreme
confidence.
Using Bryant motors to the values listed in the Physical
Data, Fan Performance, and Evaporator-Fan Motor Data
tables will not result in nuisance tripping or premature motor
failure. In addition, the unit warranty will not be affected.
13. THRU-THE-BOTTOM CONNECTIONS — The accessory
thru-the-bottom connections are needed to ensure proper
connections when routing wiring and piping through the
basepan and roof curb. This accessory is used for electric
and control power only or electric, control power, and gas
piping depending on which accessory is selected.
14. FIELD-SUPPLIED FAN DRIVES — If the factory drive sets
must be changed to obtain other wheel speeds, consult the
nearest Browning Manufacturing Co. sales office with the
required new wheel speed and the data from Physical Data
tables (center distances, motor and fan shaft diameters,
motor horsepower) for a modified drive set selection. For
minor speed changes, the fan sheave size should be
changed. (Do not reduce the size of the motor sheave; this
will result in reduced belt horse-power ratings and reduced
belt life.) All indoor fan pulleys are adjustable. See physical
data tables for rpm adjustment ranges.
15. CONDENSER COIL PROTECTION
a. PRE-COATED ALUMINUM FIN COILS have a durable
epoxy-phenolic coating applied to the fin prior to the fin
stamping process to provide protection in mildly corro-
sive coastal environments. Pre-coated coils have an
inert barrier between the aluminum fin and copper tube.
This barrier electrically disconnects the dissimilar metals
to minimize the potential for galvanic corrosion. This
economical option provides substantial corrosion protec-
tion beyond the standard uncoated coil construction.
b. COPPER-FIN COILS provide increased corrosion resis-
tance in moderate coastal environments where industrial
air pollution is not present. All copper coils eliminate bi-
metallic construction to eliminate the potential for gal-
vanic corrosion. Application in industrial environments is
not recommended due to potential attack from sulfur,
sulfur oxide, nitrogen oxides, carbon and several other
industrial airborne contaminants. In moderate seacoast
environments, copper-fin coils have extended life com-
pared to standard or pre-coated aluminum-fin coils.

c. E-COATED ALUMINUM FIN coils undergo a precisely
controlled scientific process that bonds an impermeable
epoxy coating to the specially prepared fin coil surface.
E-Coating produces a smooth, consistent coating that is
less brittle, more resilient and more durable than previ-
ous postcoating processes. E-Coated aluminum-fin coils
offer economical protection and improved coil life in
many contaminated environments.
d. E-COATED COPPER-FIN COILS provide maximum
protection in virtually all environments, this option com-
bines the continuous, impenetrable barrier of the E-
Coating process with the natural resistance of an all-cop-
per construction. E-Coated copper-fin coil assemblies
ensure long life, even in environments that combine
harsh coastal conditions with industrial contamination.
16. ECONOMI$ER IV — The EconoMi$er IV factory-installed
economizer package includes a gear-driven damper sys-
tem that modulates the return air and outdoor air supply to
the rooftop unit in order to take advantage of “free cooling”
with outdoor air when conditions are suitable. The system
utilizes industry proven technology available for integrating
the use of outdoor air for cooling with mechanical cooling
for 3 through 25-ton rooftop units. The intuitive
EconoMi$er IV microprocessor-based controller optimizes
and enhances rooftop operation through reduced energy
consumption, optimal zone comfort, and efficient equip-
ment cycling. This is accomplished by operating the com-
pressors when the outdoor air temperature is too warm,
integrating the compressors with outdoor air when free
cooling is available, and locking out the compressor when
outdoor air temperature is too cold. The detailed sequence
of operation is described in the Controls section with a brief
description of selected application items here.
a. THERMOSTAT INTERFACE — The EconoMi$er IV con-
trol was designed to work with conventional thermostats
that have Y1 (cooling stage 1), Y2 (cooling stage 2), W1
(heat stage 1), W2 (heat stage 2), and G (fan). In addi-
tion, the EconoMi$er IV will support an occupied/
unoccupied switch (typically integrated into the thermo-
stat or Thermidistat™ device). When the switch is
closed, it provides a 24-vac signal to the unit for occu-
pied mode, and provides no signal to indicate unoccu-
pied mode. The EconoMi$er IV control can be
configured to allow different minimum economizer
damper positions and to allow the use of mechanical
cooling in the occupied mode.

APPLICATION DATA (cont)
b. CONTROL FEATURES — The EconoMi$er IV controller
provides superior functionality for rooftop unit operation.
EconoMi$er IV control features are included as follows:
Remote Minimum Position — The EconoMi$er IV con-
troller can be used with a field-supplied and field-
installed remote minimum position control switch that will
enable and disable the EconoMi$er IV to open or close
the damper beyond the minimum position for modified
ventilation, providing 2 to 10 vdc output.
NOTE: Minimum position signal takes priority over the
DCV (demand control ventilation) maximum position
signal.
Demand Control Ventilation (DCV) — The EconoMi$er
IV has DCV capability when using an IAQ sensor. This
sensor is typically installed in the return duct or occupied
space. When implementing a DCV control scheme with
the EconoMi$er IV, the control algorithm will modulate
the position of the damper between two user-configured
damper positions, Maximum DCV Position and Minimum
Occupied position. Design airflow rates for these two
damper positions should be such that when the damper
is at the Maximum DCV position, enough fresh ventila-
tion air will be brought in to remove contaminants and
CO2 generated by sources other than people (i.e., since
in unoccupied mode). The Maximum DCV position is
intended to satisfy the IAQ “Base Ventilation Rate.” The
Minimum Occupied position design airflow rate should
be sufficient to satisfy ventilation requirements for
removing CO2 from all sources including people at the
maximum occupancy.
IAQ Sensors — EconoMi$er IV can be utilized with any
IAQ (CO2) sensor that provides a 2 to 10 vdc output. The
controller will modulate the outdoor air damper to pro-
vide ventilation based on the sensor output and the IAQ
setting of the controller. When used, an IAQ sensor will
modulate the damper from the minimum position (base
ventilation rate based on CO2 levels) to maximum posi-
tion (full occupancy ventilation rate).
Damper Operation — The EconoMi$er IV allows the
damper to be configured for two adjustable damper posi-
tions including maximum position and occupied mini-
mum positions. The two (2) position damper capability is
a unique feature of EconoMi$er IV and includes opera-
tion flexibility as follows:
1. Minimum Occupied Position: This adjustable position
allows a minimum ventilation (base ventilation rate)
airflow rate through the unit during occupied periods.
2. Demand Control Ventilation (DCV) Maximum Posi-
tion: A DCV maximum occupied position is provided
when using an IAQ sensor for DCV. See DCV and
Control sections for sequence. The DCV Maximum
Position limits outdoor airflow into the rooftop when
the DCV routine overrides the mixed air sensor. Set-
ting the DCV Maximum Position of the outdoor air
damper prevents large amounts of hot or cold air into
the space.
IMPORTANT: When the DCV Maximum Position is set
below the minimum position, the minimum position
overrides the maximum position, negating most DCV
functions.
Power Exhaust — The EconoMi$er IV has the capability
to control one stage of power exhaust for maintaining air
balance and pressurization. Control is activated based
on outdoor air damper position (adjustable); factory-set
at the “middle” position (dampers halfway open).
Compressor Staging — The EconoMi$er IV is an inte-
grated economizer and has the ability to utilize simulta-
neous outdoor air and compressors. The EconoMi$er IV
can be configured to support economizer and compres-
sor operation. Only one or two compressor operation is
available with 3 to 121/2 ton units.
c. CHANGEOVER STRATEGIES — The EconoMi$er IV
controller can be configured to accommodate all avail-
able economizer control strategies that place the rooftop
unit in economizer mode including:
Remote Minimum Position — Used when a remote sig-
nal from a remote minimum position control will enable
and disable the EconoMi$er IV (remote enable control).
Outdoor Dry Bulb — EconoMi$er IV will be enabled
based on the outdoor-air temperature. This is provided
standard with the EconoMi$er IV.
Differential Dry Bulb — EconoMi$er IV will be enabled
whenever the outdoor-air temperature is lower than the
return-air temperature.
Outside Air Enthalpy — EconoMi$er IV will be enabled
based on the outside air enthalpy curves as shown in the
EconoMi$er IV Changeover diagram below. The A, B,
C, and D curves shown have been in use for many years
and have been included as part of the latest
ASHRAE 90.1 energy efficiency code. The curves are
designed to take into consideration both outdoor temper-
ature and humidity. These curves are used to set up the
EconoMi$er IV controller to use the EconoMi$er IV for
free cooling when the conditions to the left of the curve
exist. When the conditions are to the right of the curve,
then outdoor air cooling will not be used and the outdoor
air damper position will be set at the minimum position.
Deciding which curve is used is a function of the outdoor
climate and the type of economizer utilized. Since
EconoMi$er IV is a fully integrated economizer, the
range where outdoor air can be utilized for free cooling is
expanded and the A and B curves may be used. The
control point table in the EconoMi$er IV Changeover dia-
gram below provides assistance for whether the A and B
curves will be suitable. In general terms, a hot and humid
climate may be a reason not to use the A curve, while a
cooler climate might be more applicable for using the A
or B curve.
The EconoMi$er IV has expanded outdoor air capability.
For a changeover economizer which cannot utilize
simultaneous economizer and compression, both A and
B curves would potentially be undesirable since the tem-
perature and humidity levels are too high without com-
pression assistance to provide effective cooling.
Therefore, most changeover economizers utilize the D
curve.
Differential Enthalpy — The EconoMi$er IV will be
enabled based on the comparison of the enthalpy of the
return air and outside air. When the outside air enthalpy
is lower than he return side, the unit will be in econo-
mizer mode.
Using the EconoMi$er IV controller for implementing
different control changeover strategies requires the use
of different combinations of dry bulb and humidity
sensors as outlined in the EconoMi$er IV Sensor Usage
table.
