belt-driven evaporator fan motors on all units (except
558F036-060).
• Ease of maintenance achieved by standard size filters, toolless filter access, simple compressor access, permanently
lubricated fan motors, optional disconnect switch, optional
115-v convenience outlet, and optional hinged access
panels.
• Perfect Humidity™ dehumidification package (not available
on 558F036-150 units). This factory-installed option improves the dehumidification capability of the rooftop unit and
helps control humidity levels in the conditioned space.
BRYANT MEANS TOP QUALITY AND RELIABILITY — Each
component utilized in these units is designed and tested for a
minimum of 15 years operation under the harshest conditions.
Every unit is thoroughly run tested at the factory in each operating mode and evacuated prior to final charging. Every coil is
leak-tested with helium particles. Automated run testing allows
accurate impartial tests and measurements which are second
to none in the industry.

Each unit contains a factory printout indicating tested
pressures, amperages, dates, and inspectors, providing certification of the unit’s status at the time of manufacture.
Units are equipped with valuable safety controls designed to
monitor and protect the unit for life. The standard safeties
include:
• low-pressure/loss-of-charge switch
• high-pressure switch
• freeze-protection thermostat
• internal compressor overload
• exclusive Cycle-LOC™ circuit board that provides compressor anti-cycling (except 558F036-150)
• refrigerant filter drier
The cabinet is constructed of galvanized steel, bonderized and
coated with a prepainted baked enamel finish. The paint finish
is a non-chalking type, and is capable of exceeding Federal
Test Method Standard No. 141 (Method 6061) 500-Hour Salt
Spray Test. In addition, all internal cabinet panel surfaces are
primed, allowing the entire unit to have a longer life and more
attractive appearance.
EASY MAINTENANCE AND INSTALLATION
All Units are Factory Shipped in the Vertical Discharge
Configuration for fit-up to standard roof curbs. (One accessory curb fits sizes 036-072; accessory curbs fit sizes 090-150
and 155-300.) The contractor can order and install the roof
curbs early in the construction stage, before decisions on size
requirements have been made.
All Units Feature Roll-Formed Baserail design with forklift
slots on 3 sides of the unit and rigging holes for easier maneuvering and installation. Stretch-wrap packaging protects the
unit during shipment and storage.

Form No. PDS 558F.36.2

4. Filter driers, which trap moisture and debris in the refrigeration system.
5. A fixed orifice metering system precisely controls refrigerant
flow (sizes 036-150), preventing slugging and floodback,
while maintaining optimum unit performance by metering the circuits individually. TXV meeting system on
sizes 155-300.
Two Independent Compressor Circuits (all 090-300 size
units) provide pinpoint comfort control, improved efficiency, and
back-up capability.

Units are Easily Converted from vertical to horizontal applications to make retrofit and add-on jobs easier. To convert
from vertical to horizontal discharge, simply relocate 2 panels
(036-150).
The same basic unit can be used for a variety of applications
and can be quickly modified at the jobsite. Standard highperformance, belt-driven, evaporator-fan motors enable the
551B036-150 units to operate in most ductwork configurations.
Ductwork Connections are Simplified by the logical 2 to 1
aspect ratio. On vertical discharge units, ductwork attaches
directly to the roof curb.
Thru-the-Bottom Service Connection capability allows power
and control wiring to be routed through the unit basepan and
roof curb (if installed), thereby minimizing roof penetrations (to
prevent water leaks). Both power and control connections are
made on the same side of the unit to simplify installation.
The Non-Corrosive, Sloped, Condensate Drain Pan is in
conformance with ASHRAE (American Society of Heating,
Refrigeration, and Air Conditioning Engineers) Standard 62 to
meet many Indoor-Air Quality (IAQ) specifications. The condensate drain pan offers both bottom and end drain capability to
minimize roof penetrations. The bottom drain can be used in
conjunction with the thru-the-bottom connections. An external
trap must be field supplied (035-150).
Standard 2-in. Throwaway Filters are easily accessed
through a removable filter access panel located directly above
the air intake hood; no tools are required to change the filters.
All Units are Designed with a Single Continuous Top Piece
to eliminate leaking at the seams or gasketing (036-150).
Belt-Driven Evaporator-Fan Motors on All Sizes allow maximum on-site flexibility without changing motors or drives (except
558F036-060).
Low-Voltage Wiring Connections are easily made due to the
terminal board which is conveniently located for quick simple
access.
Single-Point Electrical Power Connections permit easier
wire estimating and connections.
Field-Installed Accessory Electric Heaters are available in a
wide range of capacities. Single-point wiring kit makes installation simple.

BRYANT CONTROLS ADD RELIABILITY, EFFICIENCY, AND
SIMPLIFICATION
The Standard Control System is readily adaptable to all conventional and programmable thermostats.
Patented Cycle-LOC™ Protection System provides protection against compressor cycling by monitoring compressor current (except 558F036-150). When a lack of compressor current
exists, the Cycle-LOC circuit board locks out the compressors.
Cycle-LOC may be manually reset by simply switching the thermostat to OFF, and back to the Cooling or AUTO modes. No use
of the unit power disconnect switch is required.
INDOOR-AIR QUALITY (IAQ)
Bryant rooftop units utilize certain key features that assist in
improving the quality of the building air. Sloped condensate
pans eliminate possible biological growth in the rooftop unit. A
face-split indoor coil design (all 090-300 size units) proves
effective in additional moisture removal from the supply air.
Two-in. filters are standard in all rooftop units with an optional
filter status sensor available.
Another Optional Indoor-Air Quality (IAQ) Feature is the
Perfect Humidity™ dehumidification package (except 558F036150). This is a factory-installed option that provides increased
dehumidification by cooling the hot liquid refrigerant leaving the
condenser coil. The Perfect Humidity option 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 damage or poor indoor air quality due to
humid conditions. The improved latent capacity provided by the
Perfect Humidity option reduces the building’s humidity, eliminating potential property damage and making the space more
comfortable.
The Perfect Humidity option makes units ideal IAQ rooftops for
hot and humid regions. The operation of the Perfect Humidity
package can be controlled by a field-installed, wall-mounted
humidistat, or light commercial thermidistat. The circuit activates only when needed (using the accessory humidistat) as
opposed to some dehumidification systems that operate continuously. The humidistat can be set for any humidity level
between 20% and 80% relative humidity.

QUIET, EFFICIENT OPERATION AND DEPENDABLE
PERFORMANCE
All Units are Equipped with Compressors that are fully hermetic with internal vibration isolators for extremely quiet and
highly efficient operation. Compressors are mounted on an
independent plate for additional sound integrity and structural
support. Efficient condenser fan and motor design permits
operation at low sound levels.
Totally Enclosed Condenser Fan Motors and permanently
lubricated bearings provide additional dependability.
All Coils Use State-of-the-Art Internally Enhanced Copper
Tubing. Coils are thoroughly leak and pressure tested at the
factory. Condenser coils have louvered, aluminum lanced fins to
provide maximum heat transfer for optimum efficiency and easy
cleaning.
Refrigerant Circuit Protection ensures dependability. All units
have standard:
1. Loss-of-charge/low-pressure protection switch which allows
operation at lower ambient conditions while protecting
against low-charge operation.
2. Freeze-protection thermostat, which protects against evaporator coil frost build-up.
3. High-pressure switch, which protects against above normal
operating pressure.

SERVICEABILITY
Servicing a Rooftop Unit has Never Been Easier with the
new factory-installed Hinged Panel Option (except 558F036150). This option includes hinged access panels for the filter,
compressor, evaporator-fan motor, and control box areas.
These panels provide quick and simple access to the major
components by simply unlocking and swinging open the different panels. Each hinged access panel is permanently attached
to the rooftop unit, eliminating the problem of access panels
being dropped and creating a hole in the roof (potentially causing a water leak). This type of damage could void any warranty
offered for a new roof.
Standardized Components for the complete line of products
are found in all safety devices, condenser-fan motors, and control boards. This allows for greater inventory control, familiarity,
and fewer stocked parts.

Easily Accessible Refrigerant Access Ports on all discharge, suction, and liquid lines permit easy and accurate
measurements.
Resettable 24-V Circuit Breaker (Sizes 090-150) allows room
for error without replacing transformers or fuses.
Single-Side Utility Connections provide easy access to perform any necessary service.

Color-Coded Wires permit easy tracing and diagnostics.
Indoor Fan Motors are accessible through a single access
door to facilitate servicing and adjusting after installation.
Compressors and Safety Switches are Easily Accessible for
troubleshooting and system analysis.

CONTROLS
OPERATING SEQUENCE — SIZE 036-073 UNITS
Cooling, Units Without Economizer — When the thermostat
calls for cooling, terminals G and Y1 are energized. The indoor
(evaporator) fan contactor (IFC), and compressor contactor
no. 1 (C1) are energized and the indoor (evaporator) fan motor
(IFM), compressor no. 1, and condenser fan start. The outdoor
(condenser) fan motor (OFM) runs continuously while unit is
cooling.
Cooling, Units With EconoMi$er — When the outdoor-air
temperature (OAT) is above the ECON SP set point and the
room thermostat calls for Stage 1 cooling (R to G + Y1), the
indoor (evaporator) fan motor (IFM) is energized and the
EconoMi$er damper modulates to minimum position. The compressor contactor is energized to start the compressor and outdoor (condenser) fan motor (OFM). After the thermostat is
satisfied, the damper modulates to the fully closed position
when the IFM is deenergized.
When the OAT is below the ECON SP setting and the room
thermostat calls for Stage 1 cooling (R to G + Y1), the
EconoMi$er modulates to the minimum position when the IFM
is energized. The EconoMi$er provides Stage 1 of cooling by
modulating the return and outdoor air dampers to maintain a
55 F supply air set point. If the supply-air temperature (SAT) is
greater than 57 F, the EconoMi$er modulates open, allowing a
greater amount of outdoor air to enter the unit. If the SAT drops
below 53 F, the outdoor air damper modulates closed to reduce
the amount of outdoor air. When the SAT is between 53 and
57 F, the EconoMi$er maintains its position.
If outdoor air alone cannot satisfy the cooling requirements of
the conditioned space, and the OAT is above the MECH CLG
LOCKOUT set point, the EconoMi$er integrates free cooling
with mechanical cooling. This is accomplished by the strategies
below.
NOTE: Compressor has a 2-minute Minimum On, Minimum Off,
and Interstage delay timer.
1. If Y1 is energized, and the room thermostat calls for Y2
(2-stage thermostat), the compressor and OFM are energized. The position of the EconoMi$er damper is maintained at its current value.
2. If Y1 is energized for more than 20 minutes, and Y2 is not
energized (whether or not a 2-stage thermostat is used),
the compressor and OFM are energized. The position of the
EconoMi$er damper is maintained at its current value.
3. If Y1 is energized, and the compressor is already energized
(see Step 2) and the room thermostat calls for Y2, the compressor continues to operate.
4. If the compressor is energized and the thermostat is satisfied, the compressor, the OFM, and IFM are deenergized
and the EconoMi$er modulates closed.
When the OAT is below the MECH CLG LOCKOUT set point,
the compressors remain off.
Heating, Units Without Economizer — Upon a call for heating
through W1, indoor (evaporator) fan contactor (IFC) and heater
contactor no. 1 (HC1) are energized. On units equipped for
2 stages of heat, when additional heat is needed, heater contactor no. 2 is energized through W2.
Heating, Units With Economizer — When the room temperature calls for heat through terminal W1, the indoor (evaporator)
fan contactor (IFC) and heater contactor no. 1 (HC1) are energized. On units equipped for 2 stages of heat, when additional
heat is needed, heater contactor no. 2 is energized through W2.
The economizer damper moves to the minimum position. When
the thermostat is satisfied, the damper moves to the fully closed
position.

OPERATING SEQUENCE — SIZE 090-150 UNITS
Cooling, Units Without Economizer — When the thermostat
calls for cooling, terminals G and Y1 are energized. The indoor
(evaporator) fan contactor (IFC), compressor contactor no. 1
(C1) and outdoor fan contactor (OFC) are energized and the
indoor (evaporator) fan motor (IFM), compressor no. 1, and condenser fans start. The outdoor (condenser) fan motors (OFM)
run continuously while unit is cooling. If the thermostat calls for
a second stage of cooling by energizing Y2, compressor contactor no. 2 (C2) is energized and compressor no. 2 starts.
Cooling, Units With EconoMi$er — When the outdoor-air
temperature (OAT) is above the ECON SP set point and the
room thermostat calls for Stage 1 cooling (R to G + Y1), the
indoor (evaporator) fan motor (IFM) is energized and the
EconoMi$er damper modulates to minimum position. The compressor contactor is energized to start the compressor and outdoor (condenser) fan motor (OFM). After the thermostat is
satisfied, the damper modulates to the fully closed position
when the IFM is deenergized.
When the OAT is below the ECON SP setting and the room
thermostat calls for Stage 1 cooling (R to G + Y1), the
EconoMi$er modulates to the minimum position when the IFM
is energized. The EconoMi$er provides Stage 1 of cooling by
modulating the return and outdoor air dampers to maintain a
55 F supply air set point. If the supply-air temperature (SAT) is
greater than 57 F, the EconoMi$er modulates open, allowing a
greater amount of outdoor air to enter the unit. If the SAT drops
below 53 F, the outdoor air damper modulates closed to reduce
the amount of outdoor air. When the SAT is between 53 and
57 F, the EconoMi$er maintains its position.
If outdoor air alone cannot satisfy the cooling requirements of
the conditioned space, and the OAT is above the MECH CLG
LOCKOUT set point, the EconoMi$er integrates free cooling
with mechanical cooling. This is accomplished by the strategies
below.
NOTE: Compressor has a two-minute Minimum On, Minimum
Off, and Interstage delay timer.
1. If Y1 is energized, and the room thermostat calls for Y2
(2-stage thermostat), compressor no. 1 and OFM are energized. The position of the EconoMi$er damper is maintained at its current value.
2. If Y1 is energized for more than 20 minutes, and Y2 is not
energized (whether or not a 2-stage thermostat is used),
compressor no. 1 and OFM are energized. The position of
the EconoMi$er damper is maintained at its current value.
3. If Y1 is energized, and compressor no. 1 is already energized (see Step 2) and the room thermostat calls for Y2, the
compressor continues to operate. If Y2 remains energized
for more than 20 minutes, compressor no. 2 is energized.
NOTE: Compressor no. 2 cannot be energized unless there is a
signal for Y2 from the space thermostat.
4. If compressor no. 2 is energized, and the Y2 signal from the
thermostat is satisfied, compressors 1 and 2 are deenergized. Reasserting Y2 will start compressor no. 1 and (after
a 20-minute interstage delay) compressor no. 2.
5. If compressor no. 1 is energized and the thermostat is satisfied, compressor no. 1, the OFM, and IFM are deenergized
and the EconoMi$er modulates closed.
When the OAT is below the MECH CLG LOCKOUT set point,
the compressors remain off.

NOTE: Compressors have a two-minute Minimum On and Minimum Off.
1. If Y1 is energized, and the room thermostat calls for Y2
(2-stage thermostat), the compressor and OFC are energized. The position of the EconoMi$er damper is maintained at its current value.
2. If Y1 is energized for more than 20 minutes, and Y2 is not
energized (whether or not a 2-stage thermostat is used),
the compressor and OFC are energized. The position of the
EconoMi$er damper is maintained at its current value.
3. If Y1 is energized, and compressor no. 1 is already energized (see Step 2) and the room thermostat calls for Y2,

compressor no. 1 continues to operate. If Y2 remains
energized for more than 20 minutes, compressor no. 2 is

NOTE: Compressor no. 2 cannot be energized unless there is a
signal for Y2 from the space thermostat.
4. If compressor no. 2 is energized, and the Y2 signal from the
thermostat is satisfied, compressors 1 and 2 are deenergized. Re-asserting Y2 will start compressor no. 1 and
(after a 20-minute interstage delay) compressor no. 2.
5. If compressor no. 1 is energized and the thermostat is satisfied, compressor no. 1, the OFM, and IFM are deenergized
and the EconoMi$er modulates closed.
When the OAT is below the MECH CLG LOCKOUT set point,
the compressors remain off.
Freeze Protection Thermostat(s) — A freeze protection thermostat (FPT) is located on the top and bottom of the evaporator
coil. It detects frost build-up and turns off the compressor, allowing the coil to clear. Once frost has melted, the compressor can
be reenergized by resetting the compressor lockout.
Heating, Units With EconoMi$er (If Accessory Heater is
Installed) — When the room thermostat calls for heat, the heating controls are energized as described in the Heating, Units
Without EconoMi$er section. The IFM is energized and the
EconoMi$er damper modulates to the minimum position. When
the thermostat is satisfied, the damper modulates closed.
Units With Perfect Humidity™ Dehumidification Package —
When thermostat calls for cooling, terminals G and Y1 and/or
Y2 and the compressor contactor C1 and/or C2 are energized.
The indoor (evaporator) fan motor (IFM), compressors, and outdoor (condenser) fan motors (OFM) start. The OFMs run
continuously while the unit is in cooling. As shipped from the
factory, both Perfect Humidity dehumidification circuits are
always energized.
If Perfect Humidity circuit modulation is desired, a field-installed,
wall-mounted light-commercial thermidistat (with field-supplied
relay) is required. If the thermidistat is installed and calls for the
Perfect Humidity subcooler coil to operate, the relay switch
closes. This energizes the 3-way liquid line solenoid valve coils
(LLSV1 for circuit 1 and LLSV2 for circuit 2) of the Perfect
Humidity circuits, forcing the warm liquid refrigerant of the liquid
line to enter the subcooler coils.
As the warm liquid passes through the subcooler coils, it is
exposed to the cold supply airflow coming off the evaporator
coils and the liquid is further cooled to a temperature approaching the evaporator coil leaving-air temperature. The state of the
refrigerant leaving the subcooler coils is a highly subcooled
liquid refrigerant. The liquid then enters a thermostatic expansion valve (TXV) where the liquid is dropped to the evaporator
pressure. The TXVs can throttle the pressure drop of the liquid
refrigerant and maintain proper conditions at the compressor
suction valves over a wide range of operating conditions.
The liquid proceeds to the evaporator coils at a temperature
lower than normal cooling operation. This lower temperature is
what increases the latent and sensible capacity of the evaporator coils.
The 2-phase refrigerant passes through the evaporators and is
changed into a vapor. The air passing over the evaporator coils
will become colder than during normal operation as a result of
the colder refrigerant temperatures. However, as it passes over
the subcooler coils, the air will be warmed, decreasing the sensible capacity and reducing the sensible heat of the rooftop unit.

12

CONTROLS (cont)
As the refrigerant leaves the evaporator, the refrigerant passes
a subcooler control low-pressure switch (S-LPS1 for circuit 1 or
S-LPS2 for circuit 2) in the suction line. This low-pressure
switch will deactivate the Perfect Humidity™ package when the
suction pressure reaches 60 psig. The subcooler control lowpressure switch is an added safety device to protect against
evaporator coil freeze-up during low ambient operation. The
subcooler control low-pressure will only deactivate the 3-way
liquid line solenoid valve in the Perfect Humidity circuit. The
compressors will continue to run as long as there is a call for
cooling, regardless of the position of the subcooler control lowpressure switch. The 3-way solenoid valve and the Perfect
Humidity package will be reactivated only when the call for cooling has been satisfied, the subcooler control low-pressure
switch has closed above 80 psig, and a new call for cooling
exists. The crankcase heaters on the scroll compressors
provide additional protection for the compressors due to the
additional refrigerant charge in the subcooler.

When the thermidistat is satisfied, the relay internal switch
opens, cutting power to and deenergizing the LLSVs. The
refrigerant is routed back through the evaporators and the
subcooler coils are removed from the refrigerant loops. When
the thermostat is satisfied, C1 and C2 are deenergized and
the compressors, IFM, and OFMs shut off. If the thermostat
fan selector switch is in the ON position, the IFM will run
continuously.

APPLICATION DATA
1. CONDENSATE DRAIN PAN — A sloped condensate drain
pan is supplied on all units. The condensate drain pan must
be externally trapped. Condensate drains are located on
both the bottom and end of the unit. The bottom drain can
be used for thru-the-curb connections.
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 horizontal discharge applications, attach ductwork to flanges. Fieldsupplied flanges can be attached to horizontal discharge
openings and all ductwork attached to flanges.
3. THRU-THE-BOTTOM SERVICE CONNECTIONS — Thruthe-bottom connections allow field power wires and control
wires to enter through the basepan.
4. THERMOSTAT — Use of 2-stage cooling thermostat is
recommended for all units equipped with economizer.
5. HEATING-TO-COOLING CHANGEOVER — All units are
automatic changeover from heating to cooling when automatic changeover thermostat and subbase are used.
6. AIRFLOW — Units are draw-thru on cooling and blow-thru
on heating.
7. MAXIMUM AIRFLOW — To minimize possibility of condensate blow-off from evaporator, airflow through units should
not exceed 500 cfm/ton.
8. MINIMUM AIRFLOW — Minimum airflow for cooling is
300 cfm/ton for unit sizes 036-240, 280 cfm/ton for size 300.
9. MINIMUM AMBIENT OPERATING TEMPERATURE —
Minimum operating temperature for standard 036-150 units
is 25 F, for standard 155-300 units is 40 F. With accessory
Motormaster® or Motormaster IV control, units can operate
at outdoor temperatures down to –20 F.
10. MAXIMUM OPERATING OUTDOOR-AIR TEMPERATURE
— Maximum outdoor-air operating temperature for cooling
is 125 F (115 F for 558F036-150 units).

11. MOTOR DATA — Due to Bryant’s internal unit design (drawthru over the motor), air path, and specially designed
motors, the full horsepower (maximum continuous bhp)
listed in the Physical Data table and in 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.
12. PERFECT HUMIDITY™ DEHUMIDIFICATION PACKAGE
— This option provides greater dehumidification by further
subcooling the hot liquid refrigerant leaving the condenser
coil. The Perfect Humidity package consists of a subcooling
coil located on the leaving-air side of the evaporator coil.
The location of the coil in the indoor airstream enhances the
latent capacity of the rooftop units by up to 40%.
Many buildings suffer damage or have poor indoor-air quality due to overly humid conditions. Building humidity must
be controlled for the following reasons:
a. INDOOR-AIR QUALITY — Humidity is a major factor in
the growth and propagation of mold and mildew in a
building. The mold and mildew can spread quickly and
grow in carpets and ductwork and on walls, and often
causes cases of sick building syndrome. This syndrome
can lead to employee absenteeism due to illness, lower
worker productivity, and increased health care costs. The
American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) recommends that relative
humidity levels in buildings be maintained below 70%.
b. COMFORT LEVELS — High humidity levels cause the
occupied space to become uncomfortable, because
humidity interferes with the body’s natural cooling process (evaporation at the skin surface).

APPLICATION DATA (cont)
c. HUMIDITY DAMAGE — Humidity causes property
damage, such as stained wallpaper and ceiling tiles.
Humidity can also damage books and artwork, and create strong odors in carpets. In addition, humidity can
contribute to unacceptable product quality in industrial
processes.
d. IMPROPER VENTILATION — Buildings in hot and
humid geographical areas cannot be properly ventilated
due to high humidity levels outdoors, resulting in poor
indoor-air quality.
e. EQUIPMENT INEFFICIENCY — Humidity can cause
inefficient operation of refrigerators and freezers.
f. INCREASED ENERGY COSTS — Because of high
humidity levels and less comfortable conditions, thermostat set points are lowered to force the HVAC (heating,
ventilation, and air conditioning) equipment to run longer
and work harder to lower the humidity levels. Also, in an
attempt to control humidity, system designers typically
oversize HVAC equipment and add reheat capability to
get the desired latent capacity. This results in higher initial equipment costs, as well as increased energy
expenses throughout the life of the unit.
Applications
There are many different rooftop unit applications that are
susceptible to problems caused by high humidity levels.
Some common applications include:
a. RESTAURANTS — The kitchen areas of restaurants
have many humidity-producing activities, such as dish
washing and cooking.
b. SUPERMARKETS — High humidity levels cause inefficiency in operation of refrigeration and freezer systems.
c. MUSEUMS AND LIBRARIES — Humidity can damage
books and artwork.
d. GYMNASIUMS, LOCKER ROOMS, AND HEALTH
CLUBS — Shower areas and human perspiration cause
uncomfortable occupied space conditions.
e. HOT AND HUMID CLIMATES — The southeastern
United States is a good example of this application. The
Perfect Humidity dehumidification package becomes
particularly useful when increased amounts of the hot
and humid outdoor air need to be brought into the building for proper ventilation.
13. PERFECT HUMIDITY DEHUMIDIFICATION PACKAGE
DESIGN EFFECTS — To fully understand the operation of
the Perfect Humidity dehumidification package, refer to the
pressure enthalpy curve, and analyze the Perfect Humidity
package effects on the refrigerant in the rooftop unit. The
pressure enthalpy curve shows the refrigerant cycle for a
rooftop unit.
Standard Unit Refrigerant Cycle
At point no. 1 in the pressure enthalpy curve, vapor leaving the
compressor at a high pressure and a high temperature enters
the condenser. The condenser removes heat from the refrigerant, lowers its temperature, and changes it to a liquid. At point
no. 2, the liquid leaves the condenser and enters a fixed expansion device that lowers the pressure of the refrigerant. At point
no. 3, the liquid enters the evaporator coil, where the refrigerant
increases in temperature and changes back to a vapor. At point
no. 4, the vapor leaves the evaporator and reenters the
compressor.

Refrigerant Cycle Using Perfect Humidity™ Dehumidification
Package
When a subcooler coil is added to the rooftop unit, the refrigerant is affected in such a way that the unit latent capacity is
increased. The refrigerant cycle follows the same path from
point no. 1 to point no. 2 as the standard refrigerant cycle without a subcooler (see the pressure enthalpy curve). However, at
point no. 2, the liquid refrigerant enters the subcooler coil where
the temperature is lowered further. At point no. 2A, this subcooled liquid enters the TXV, which drops the pressure of the
liquid. At point no. 2B, the liquid enters the fixed orifice metering
device. The refrigerant leaves this device as a saturated vapor
and enters the evaporator at point no. 2C. The improved refrigeration effect can now be seen between point no. 2C and point
no. 3. The increase in the total refrigeration effect is the additional enthalpy gained from point no. 2C to point no. 3. However,
the subcooler coil rejects this added refrigeration effect to the
air downstream of the evaporator coil, thus maximizing the overall latent effect. This improved latent effect is a direct result of
the addition of the Perfect Humidity subcooler coil to the refrigerant cycle.
Latent Capacity Effects
Refer to the psychrometric chart to see how the sensible heat
factor decreases when the optional Perfect Humidity dehumidification package is installed. This chart contains data for the
5-ton unit operation, both with and without the Perfect Humidity
package, at 1750 cfm. Point no. 1 on the chart represents the
return-air dry bulb (80 F) and wet bulb (67 F) conditions. Point
no. 2 represents the supply-air conditions for a standard rooftop
unit without the Perfect Humidity dehumidification package.
Point no. 3 represents the supply-air conditions for a rooftop unit
with the Perfect Humidity package. By connecting point no. 1
and point no. 2 on the chart and finding the intersection on the
sensible heat factor scale, the sensible heat factor is 0.73. Connect point no. 1 and point no. 3, and see that the sensible heat
factor is 0.58. This is a 17.5% increase in latent capacity for the
given conditions. This increase in latent capacity allows the
rooftop units to remove more moisture from the conditioned
space; thus lowering the humidity levels.
Dehumidification Effects
Further evidence of dehumidification can be seen by analyzing
the pounds of water per pound of dry air found in the supply air.
At point no. 2 in the psychrometric chart, there are 65 grains
(0.0092 lb) of moisture per pound of dry air. At point no. 3, there
are 58 grains (0.0083 lb) of moisture per pound of dry air. This
is a 12.1% decrease in the amount of water in the supply air.
14. PERFECT HUMIDITY DEHUMIDIFICATION PACKAGE
OPERATING PERFORMANCE — Perfect Humidity dehumidification package operation does not affect the electrical
data. The electrical data remains the same either with or
without the Perfect Humidity package.
The operating and shipping weights will be slightly
increased with the addition of the Perfect Humidity subcooler. See the Physical Data table for added base unit
weight with this option.
Refer to cooling performance data, both with and without
the Perfect Humidity dehumidification package. Note the
greatly improved latent capacity with the Perfect Humidity
dehumidification package.
Static pressure is also slightly affected by the addition of the
Perfect Humidity dehumidification package. See Static
Pressure Drop table on page 94 when using this option.

APPLICATION DATA (cont)
• Improved humidity control allows increased outdoor-air ventilation in hot and humid geographical areas. Humidity control
also helps to improve the indoor-air quality of the building.
• The Perfect Humidity dehumidification package is factory
installed. There are no additional field installation costs.
There is also no need to purchase a roof curb from another
manufacturer, as standard Bryant roof curbs will accommodate the rooftop units which have the Perfect Humidity dehumidification package option installed.
• The Perfect Humidity dehumidification package is engineered
and manufactured by Bryant for Bryant rooftop units. All
application support, service, and warranty issues can therefore be handled through one company.
• The slightly lower sensible capacities obtained when using
the Perfect Humidity dehumidification package allow the unit
to operate for an extended period of time. The more the unit
operates, the more air is exposed to the subcooling coil. This
rooftop unit increased latent capacity results in lower relative
humidity levels in the occupied space.
• It is no longer necessary to oversize equipment and add
reheat devices to properly dehumidify your building. In a typical scenario, a building owner may need 39,000 Btuh of sensible capacity and 23,000 Btuh of latent capacity (62,000 total
Btuh). To accomplish this without the Perfect Humidity dehumidification package, a 71/2-ton unit with a reheat device
would be necessary to attain the higher latent capacity
required. This results in a large up-front expense to oversize
the equipment from a standard 5-ton to a 71/2-ton unit.
The building owner can now purchase a 5-ton unit with the
Perfect Humidity dehumidification package for a small additional up-front charge, and no reheat device will be necessary
to satisfy the cooling requirements. This reduces both installation costs and operating costs throughout the life of the
product.

15. PERFECT HUMIDITY DEHUMIDIFICATION PACKAGE
FEATURES AND BENEFITS
• The Perfect Humidity dehumidification package can improve
the humidity control of your rooftop equipment by up to 40%.
This greatly reduces the risk of sick building syndrome by
reducing biological growth in both ductwork and the rest of
the building.
• The Perfect Humidity dehumidification package improves
comfort levels in the building by better controlling the humidity. This improved comfort level allows building tenants to
raise the cooling set point on the thermostats for accumulated energy savings.
• Better humidity control lowers the risk of humidity-induced
property damage.
• The Perfect Humidity dehumidification package permits building refrigerators and freezers to operate more efficiently due
to lower relative humidity levels. This is the perfect solution for
supermarket applications.
• The Perfect Humidity subcooling circuit can be operated by a
humidity sensor. If the sensor is used, the Perfect Humidity
circuit will then only operate when needed. If the humidity levels in the occupied space are acceptable (such as in the
spring and fall seasons), the Perfect Humidity circuit will not
operate. The rooftop unit is then able to operate to its full sensible potential, which provides more efficient performance
and energy savings.
• At lower outdoor temperatures, rooftop units with dehumidification devices are subject to low suction pressure conditions.
The Perfect Humidity dehumidification package contains a
low-pressure switch that deactivates the Perfect Humidity
dehumidification package under low suction pressure conditions without deactivating the compressors.

II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter cooling capacity table for 558F048 on page 36 at
condenser entering dry bulb temperature 95 F, air entering
evaporator at 1600 cfm, 80 F edb and 67 F ewb. The
558F048 unit will provide a total cooling capacity
of 50,500 Btuh, and a sensible heating capacity of
35,600 Btuh. For evaporator-air temperatures other than
80 F edb, calculate sensible heat capacity correction as
required using the formula 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 calculate net capacities, see Step V.
III SELECT ELECTRIC HEAT.
Heating load required is 50,000 Btuh.

IV DETERMINE FAN SPEED AND MOTOR HORSEPOWER
REQUIREMENTS AT DESIGN CONDITIONS.
Enter Accessory/FIOP Static Pressure table on page 61 at
selected unit size and heater kW.
Find that at given air quantity (1600 cfm), pressure loss is
0.09 in. wg.
Before entering the Fan Performance tables, calculate the
total static pressure required based on unit components.
From the given find:
External static pressure
0.75 in. wg
16 kW Heater static pressure
0.09 in. wg
Total static pressure
0.84 in. wg
Enter Fan Performance table for the alternate motor vertical discharge unit 558F048 on page 41. At 1600 cfm and
0.84 in. wg external static pressure, the fan speed is
1038 rpm and the watts are 877. (Interpolation is necessary.) The alternate motor and drive is suitable.
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 = 877
Determine net cooling capacity using the following
formula:
Net capacity

= Gross capacity – IFM heat
= 50,500 Btuh – 877 Watts (3.413

Btuh
)
Watt

= 50,500 Btuh – 2992 Btuh
= 47,508 Btuh
Net sensible capacity = 35,600 Btuh – 2992 Btuh
= 32,608 Btuh
As demonstrated above, the 558F048 with the 16.0 kW
electric heater and an alternate motor meets the cooling
capacity, sensible heating capacity, and heating capacity
requirements.

50,000 Btuh
= 14,654 Watts of heat required
3.412 Btu/W
= 14.7 kW
Enter the Electric Heating Capacities table on page 64 for
the 558F048 at 230-3-60. The 16.0 kW electric heater
most closely satisfies the heat required.
To calculate kW at 230 v, use the multiplication factors
table on page 64.
16.0 x .918 = 14.7 kW
16.0 x .918 x 3.413 = 50,115 Btuh gross capacity

480 v, and 600 v. Heaters are rated at 240 v, 480 v, or 600 v. If power
distribution voltage to unit varies from rated heater voltage, heater kW
will vary accordingly. To determine heater capacity at actual unit voltage, multiply 240 v, 480 v, or 600 v capacity by multipliers found in
table on page 64.
†Used to determine minimum disconnect size per NEC.
**Heaters are field installed only.
††Fuse or HACR circuit breaker.
||Fusing in single point box provides the required branch circuit
protection.

= 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
457
= 1.53%
This amount of phase imbalance is satisfactory as it is below the
maximum allowable 2%.

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
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
max voltage deviation from average voltage
= 100 x
average voltage

IMPORTANT: If the supply voltage phase imbalance is more than
2%, contact your local electric utility company immediately.

SELECTION PROCEDURE (With 551B048 Example)
I DETERMINE COOLING AND HEATING REQUIREMENTS AT DESIGN CONDITIONS.
Given:
Required Cooling Capacity (TC). . . . . . . . . . . 44,000 Btuh
Sensible Heat Capacity (SHC) . . . . . . . . . . . . 32,000 Btuh
Required Heating Capacity. . . . . . . . . . . . . . . 50,000 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) . . . . . . . . . . 230-3-60
II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter the Cooling Capacities table on page 79 at condenser entering temperature of 95 F, evaporator-air entering at 1600 cfm and 80 F db and 67 F wb. The 551B048
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
the notes following the Cooling Capacities tables.
For this example:
Correction factor = 1.1 x (1 – .21) x (82 – 80)
= 1.738
Multiply the correction factor 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 37.48 MBtuh (37,481 Btuh).
NOTE: Unit ratings are gross capacities and do not
include the effect of evaporator-fan motor heat. To calculate net capacities, see Step V.
III SELECT ELECTRIC HEAT.
Heating load required is 50,000 Btuh.
50,000
3.413 Btuh/kW

IV DETERMINE FAN SPEED AND POWER REQUIREMENTS 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 on page 94,
find:
External static pressure

Enter the Fan Performance table for 551B048 vertical discharge unit on page 85. At 1600 cfm, the standard motor
will deliver 1.20 in. wg static pressure and 1.15 Bhp. This
will adequately handle the job requirements.
V DETERMINE NET CAPACITIES.
Capacities are gross and do not include the effect of
indoor (evaporator) fan motor (IFM) heat. To determine
input power to the motor, convert bhp to watts using the
Evaporator-Fan Motor Efficiency table on page 94.
Bhp x 746 Watts/Bhp
IFM Watts =
Motor Efficiency
=

1.15 x 746
.75

=

1144

Determine net cooling capacity as follows:
Net capacity = gross capacity – IFM heat
=

48,900 Btuh

– (1144 Watts
Btuh
)
Watts
3904 Btuh

x 3.413
=

48,900 Btuh

=

44,996 Btuh

–

Net sensible capacity = 37,481 Btuh – 3904 Btuh
= 33,577 Btuh

= 14.6 kW of heat required

Determine net heating capacity as follows:
Net capacity = gross capacity + IFM heat

Enter the electric Heating Capacities table on page 97 for
551B048 at 208/230 (3 phase). The accessory 16.0 kW
heater at 240 v most closely satisfies the heating required.
To calculate kW at 230 v, use the Multiplication Factors
table on page 97.
16.0 x .92 = 14.7 kW
16.0 x .92 x 3413 = 50,240 Btuh gross capacity

= 50,240 + 3904
= 54,144 Btuh

tlwb = wet-bulb temperature corresponding to enthalpy of
air leaving indoor coil (hlwb)
hlwb = hewb –

total capacity (Btuh)
4.5 x cfm

where hewb = enthalpy of air entering indoor coil
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F db, subtract (corr factor x cfm) from SHC.
Above 80 F db, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 – BF) x (db – 80)

Compressor Motor Power Input
Sensible Heat Capacity (1000 Btuh) Gross
Total Capacity (1000 Btuh) Gross

tlwb = wet-bulb temperature corresponding to
enthalpy of air leaving indoor coil (hlwb)
hlwb = hewb –

total capacity (Btuh)
4.5 x cfm

where hewb = enthalpy of air entering indoor coil
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F db, subtract (corr factor x cfm) from SHC.
Above 80 F db, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 – BF) x (db – 80)

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
sensible heat capacity (Btuh)
tldb = tedb –
1.1 x cfm

LEGEND
Bypass Factor
Entering Dry Bulb
Entering Wet Bulb
Compressor Motor Power Input
Sensible Heat Capacity (1000 Btuh) Gross
Total Capacity (1000 Btuh) Gross

tlwb = wet-bulb temperature corresponding to
enthalpy of air leaving indoor coil (hlwb)
hlwb = hewb –

total capacity (Btuh)
4.5 x cfm

where hewb = enthalpy of air entering indoor coil
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F db, subtract (corr factor x cfm) from SHC.
Above 80 F db, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 – BF) x (db – 80)

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 7
457
= 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. Non-fused disconnect switch cannot be used when rooftop unit electrical
ratings exceed 80 amps.
4. 575-v units have UL, Canada approval only. Electric heaters are not available for 036-072, 575-v units.

*Used to determine minimum disconnect per NEC.
†Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v or 575 v.
If power distribution voltage to unit varies form rated heater voltage, heater kW
will vary accordingly.
**Fuse or HACR circuit breaker per NEC.
††Units have 2 condenser-fan motors.
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.
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 ImbalanceExample: Supply voltage is 460-3-60.

SELECTION PROCEDURE (with 559F180 example)
From the given and the Accessory/FIOP Static Pressure
table on page 125 find:
External static pressure
0.60 in. wg
Economizer static pressure
0.04 in. wg
Total static pressure
0.64 in. wg
Enter the Fan Performance table 559F180 (page 123) at
4,500 cfm and 0.64 in. wg external static pressure. By
interpolation, find that the rpm is 905 and the watts are
1503.
IV 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 III above.
IFM Watts = 1503
Determine net cooling capacity using the following
formula:
Net capacity = Gross capacity – IFM heat
= 178,000 Btuh – 1503 Watts
Btuh
(3.412
)
Watts
= 178,000 Btuh – 5128 Btuh
= 172,872 Btuh
Net sensible capacity = 117,000 Btuh – 5128 Btuh
= 111,872 Btuh
The calculations show that a 559F180 unit with the
standard motor and standard low-medium static drive is
the correct selection for the given conditions.

II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Cooling Capacities table for 559F180 (page 119) at
condenser entering temperature 95 F, evaporator air entering at 4,500 cfm and 67 F wb. The 559F180 unit will provide a total cooling capacity of 178,000 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 formula 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 calculate net capacities, see Step IV.
III DETERMINE FAN SPEED AND POWER REQUIREMENTS AT DESIGN CONDITIONS.
Before entering the Fan Performance tables, calculate the
total static pressure required based on unit components.

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v, and
600 v. Heaters are rated at 240 v, 480 v, or 600 v. If power distribution voltage to
unit varies from rated heater voltage, heater kW will vary accordingly. To determine heater capacity at actual unit voltage, multiply 240 v, 480 v, or 600 v capacity by multipliers found in table on page 110.
†Fuse or HACR circuit breaker.

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. MCA calculation for 559F180-300 units with electric heaters over 50 kW =
(1.25 x IFM amps) + (1.00 x heater FLA).

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 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.

SELECTION PROCEDURE (with 558F240 Example)
I DETERMINE COOLING AND HEATING REQUIREMENTS AT DESIGN CONDITIONS.
Given:
Required Cooling Capacity . . . . . . . . . . . . . 230,000 Btuh
Sensible Heat Capacity . . . . . . . . . . . . . . . . 170,000 Btuh
Required Heating Capacity . . . . . . . . . . . . . . . . . . . 75 kW
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 . . . . . . . . . . . . . . . . . . 0.4 in. wg
Electrical Characteristics (V-Ph-Hz). . . . . . . . . . . 460-3-60
Vertical discharge unit with optional economizer required.
edb — Entering dry-bulb
ewb — Entering wet-bulb
II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Cooling Capacities table for 558F240 (page 140 at
condenser entering temperature 95 F, evaporator air entering at 8,000 cfm and 67 F wb. The 558F240 unit will provide a total cooling capacity of 249,000 Btuh and a
sensible heating capacity of 188,000 Btuh. For air entering
evaporator at temperatures other than 80 F edb, calculate
sensible heat capacity correction as required using the formula 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 calculate net capacities, see Step V.
III SELECT HEATING CAPACITY OF UNIT TO PROVIDE
DESIGN CONDITION REQUIREMENTS.
In the Electric Resistance Heater table (page 130) select
the 75 kW output heater.

IV DETERMINE FAN SPEED AND POWER REQUIREMENTS 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 145 find:
External static pressure
0.40 in. wg
Electric heater static pressure
0.22 in. wg
Total static pressure
0.62 in. wg
Enter the Fan Performance table 558F240 (page 144) at
8,000 cfm and 0.62 in. wg external static pressure. By
interpolation, find that the rpm is 1061 and the watts are
4552.
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 = 4552
Determine net cooling capacity using the following
formula:
Net capacity = Gross capacity – IFM heat
= 249,000 Btuh – 4552 Watts
Btuh
(3.412
)
Watts
= 249,000 Btuh – 15,531 Btuh
= 233,469 Btuh
Net sensible capacity = 188,000 Btuh – 15,531 Btuh
= 172,469 Btuh
The calculations show that a 558F240 unit with the
standard motor and standard low-medium static drive is
the correct selection for the given conditions.

NOTES:
1. Maximum continuous bhp for the standard motor is 6.13. The maximum continuous watts
is 5180. Do not adjust motor rpm such that motor maximum bhp and/or watts is
exceeded at the maximum operating cfm.
2. See page 145 for general fan performance notes.

*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.

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v, and
600 v. Heaters are rated at 240 v, 480 v, or 600 v. If power distribution voltage to
unit varies from rated heater voltage, heater kW will vary accordingly. To determine heater capacity at actual unit voltage, multiply 240 v, 480 v, or 600 v capacity by multipliers found in table on page 130. Electric heaters are field installed.
†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 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
max voltage deviation from average voltage
= 100 x
average voltage

7
457
= 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. MCA calculation for 558F180-300 units with electric heaters over 50 kW =
(1.25 x IFM amps) + (1.00 x heater FLA).
% Voltage Imbalance = 100 x

SELECTION PROCEDURE
Enter the Accessory/FIOP Static Pressure — 551A155180 Units table at the selected unit size, cfm, and kW
heater size to determine heater pressure drop.
Calculate pressure drop:
Design External Static Pressure
1.45
56 kW Heater Static Pressure
+0.12
1.57 in. wg (ESP)
Enter Fan Performance tables for 551A180 at 6,000 cfm
and 1.57 in. wg. The rpm is 1184 and the Bhp is
4.43 (interpolation required). The factory-installed 5 hp
motor and alternate 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 551A180 at 6,000 cfm and 1.57 in. wg. Input
watts to the motor are 3772 (interpolation required).
Determine net cooling capacity and net sensible cooling
capacity using the following formulas:
IFM Heat = Input Watts x 3.412 Btuh/Watt
= 3772 x 3.412
= 12,870 Btuh
Net Capacity = Gross Capacity – IFM Heat
= 190,000 – 12,870
= 177,130 Btuh
Net Sensible Cap. = Gross Sensible Cap. – IFM Heat
= 136,000 – 12,870
= 123,130 Btuh
The calculations show that a 551A180 unit with the 56 kW
heater is the correct 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.

I DETERMINE COOLING AND HEATING REQUIREMENTS AT DESIGN CONDITIONS.
Given:
Required Gross Cooling
Capacity (TC) . . . . . . . . . . . . . . . . . . . . . . 168,000 Btuh
Gross Sensible Heat
Capacity (SHC) . . . . . . . . . . . . . . . . . . . . 121,000 Btuh
Required Heating Capacity . . . . . . . . . . . . . 110,000 Btuh
Condenser Entering Air Temperature . . . . . . . . . . . . 95 F
Indoor Air Temperature . . . . . . . . . . . .80 F edb, 67 F ewb
Evaporator Air Quantity . . . . . . . . . . . . . . . . . . . 6,000 cfm
External Static Pressure . . . . . . . . . . . . . . . . . 1.45 in. wg
Electrical Characteristics (V-Ph-Hz). . . . . . . . . . . 230-3-60
II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Cooling Capacities table for 551A180 at condenser
entering temperature of 95 F, evaporator air quantity of
6,000 cfm, and indoor air temperature of 67 F. The
551A180 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 ELECTRIC HEAT.
Heating load required is 110,000 Btuh.
110,000 Btuh
= 32,239 Watts Required
3.412 Btu/W
= 32.2 kW required
Enter the Electric Resistance Heater Data table, on
page 150, for the 551A180 unit at 230-3-60. The 56 kW
(52 kW at 230 v) heater most closely satisfies the heat
required.
IV DETERMINE FAN SPEED AND POWER REQUIREMENTS 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 evaporator coil. Refer to Accessory/FIOP Static Pressure table
for added pressure drops.
