Features/Benefits
Every compact one-piece
unit arrives fully assembled,
charged, tested, and ready to
run.
48 Series — 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 Carrier
rooftop units, provides built-in diagnostic
capability. An LED (light-emitting diode)
simplifies troubleshooting by providing
visual fault notification and 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 reliability 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
minimizes service costs. The IGC also
maximizes heating efficiency 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
heating efficiency.
The efficient in-shot burners and
all ignition components are contained in
an easily removable, compact assembly.
The California Air Quality Management Districts NOx requirement of
40 nanograms/joule or less is met on 004006 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 automatically 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 conditioned 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 accessory LP (liquid propane) conversion kit is available.
All units have a flame rectification sensor to quickly sense the burner flame and
ignite burners almost immediately. Fast
shutdown 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
temperatures 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 further short cycles. This safety feature is provided exclusively on Carrier rooftop units. The
rollout switch also deenergizes the gas
valve in the event of a flame rollout.
Quiet, efficient operation and
dependable performance
Compressors have vibration isolators for
quiet operation. Efficient fan and motor
design permits operation at low sound
levels.
Unit sizes 008-028 offer lower utility
costs through part-load operation using 2
or 3 stages of cooling.
Quiet and efficient operation is provided by belt-driven evaporator fans (standard on all units over 5 tons). The beltdriven evaporator-fan is equipped with
variable-pitch pulleys which allow adjust-
ment within the rpm ranges of the factorysupplied pulleys.
Increased operating efficiency is
achieved through computer-designed
coils featuring staggered internally enhanced copper tubes. Fins are rippleedged for strength, lanced, and double
waved for higher heat transfer.
Durable, dependable construction
Designed for durability in any climate,
the weather-resistant cabinets are constructed 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 003-014 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 dependability.
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 decisions 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 003-014 only).
To convert 003-014 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 015-028 units from vertical
to horizontal discharge, use the optional
horizontal supply/return adapter roof curb
(48HJ015,017) or accessory conversion
kit (48HJ020-028).
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 accessory 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 basep an, thereby minimizing
roof penetrations (to prevent water leaks).
(003-014 units thru-the-bottom connection requires a 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 003-014) permits either
an external horizontal side condensate
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
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. Carrier-specified hermetic compressors are equipped
with compressor overcurrent and overtemperature protection to ensure dependability.

Features/Benefits (cont)
All units have Carrier’s exclusive
Acutrol™ (003-014) or TXV (thermostatic expansion valve) metering device (015028) 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 dampers
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 temperature 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 temperature 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$er IV is used with the standard
rooftop unit controls and includes an industry standard, stand-alone, solid-state controller. The control can be used with a CO2
sensor for DCV (demand control ventilation) operation. For direct digital control
(DDC) applications, the EconoMi$er2 can
be operated using PremierLink controls or
a third party controller. The EconoMi$er2
includes 4 to 20 mA actuator capability for
demand control ventilation applications.
All economizers incorporate a parallel
blade, gear-driven damper system for efficient air mixing and reliable control. In
addition, the standard damper actuator includes a spring return to provide reliable
4
closure on power loss. The economizers
for sizes 003-014 are equipped with up to
100% barometric relief capability for high
outdoor airflow operations. Factory-installed economizers for unit sizes 003-014
are available for vertical return only.
Economizers for unit sizes 015-028 are
compatible for vertical or horizontal return. An optional field-installed barometric relief package is available for size 015028 units.
In addition, single-stage power
exhaust is available as a field-installed
accessory for EconoMi$er IV to help
maintain proper building pressure.
For units without economizer, yearround ventilation is enhanced by an optional manual outdoor-air damper. On
003-014 units, a 25% or 50% manual
damper is available as a field-installed accessory. Unit sizes 015-028 are equipped
with a manual 25% damper.
Service options (48HJ015-017 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 003-014).
For sizes 015, 017, connect the outlet
to a field-supplied and properly fused
branch circuit power supply.
• 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 capability to further protect
service personnel.
Carrier PremierLink™ controls
add reliability, efficiency, and simplification
The PremierLink direct digital controls
can be ordered as a factory-installed option (003-014 only) or as a field-installed
accessory (003-028). Designed and manufactured exclusively by Carrier, the controls can be used to actively monitor and
control all modes of operations, as well as
monitor the following diagnostics and
features: unit number, zone temperature,
zone set point, zone humidity set point,
discharge air temperatures, fan status,
stages of heating, stages of cooling,
damper position, outdoor-air temperature,
outdoor humidity level, filter
status, fire shutdown status, IAQ (indoor
air quality) set point, enthalpy status, differential enthalpy status, heat/cool lockout, cfm set point, pre-occupancy purge,
economizer controls and early morning
warm-up.
This controller has a 38.4K baud communications capability and is compatible
with ComfortLink™ controls, CCN (Carrier Comfort Network®) and ComfortVIEW™ software. The Scrolling Marquee and Navigator™ display are optional
tools that can be used for programming
and monitoring the unit for optimal performance. The addition of the Carrier CO2
sensor in the conditioned space provides
ASHRAE (American Society of Heating,
Refrigeration, and Air Conditioning Engineers) 62-99 compliance and Demand
Control Ventilation.
The PremierLink peer-to-peer, Internet
ready communicating control is designed
specifically for Constant Volume (CV)
and Variable Volume and Temperature
(VVT®) applications. This comprehensive controls system allows all Carrier 3
to 25 ton rooftops with a 3-wire communications bus to be daisy chained together
on a roof to create a fully functional
HVAC (heating, ventilation, and air conditioning) automation system.
Indoor-air quality (IAQ) begins
with Carrier rooftops
Sloped condensate pans minimize biological growth in rooftop units in accordance
with ASHRAE 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 Econo-Mi$er
IV outdoor air damper option/accessory
to aid the IAQ benefits.
Humidi-MiZer™ adaptive dehumidification system (003-014)
Carrier’s Humidi-MiZer adaptive dehumidification system is an all-inclusive
factory-installed option that can be
ordered with any Weathermaster®
48HE003-006 and 48HJ004-014 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 Carrier’s Weathermaster
48HJ004-014, 2-12.5 tons rooftop products to provide unprecedented flexibility
to meet year-round comfort conditions.
The Humidi-MiZer adaptive dehumidification system has the industry’s only dual
dehumidification mode setting. The
Humidi-MiZer system includes two new
modes of operation. The Weathermaster
rooftop coupled with the Humidi-MiZer
system is capable of operating in normal
design cooling mode, subcooling mode,
and hot gas reheat mode. Normal Design
Cooling mode is when the unit will oper-
ate under its normal sequence of operation by cycling compressors to maintain
comfort conditions. Subcooling mode
will operate to satisfy part load type conditions 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 dehumidification operation.The Humidi-MiZer™ option
includes a low ambient controller and
compressor crank case heaters.
COBRA™ energy recovery units
(sizes 003-014 only)
Carrier’s factory-installed optional COBRA units recover energy from the building exhaust air and pre-condition ventilation air for the rooftop unit during winter
and summer operation. These units are
designed to satisfy the higher ventilation
requirements and other building codes
while minimizing energy costs.
Factory installation of the 62AQ section provides the benefit of reduced fieldinstallation time, single point power connections, and the assurance of a factory
test for the complete COBRA unit. The
COBRA energy recovery section requires less maintenance than other energy
recovery systems and can be serviced by
any qualified refrigeration technician.
The COBRA energy recovery units utilize Carrier’s high-efficiency 48HE003006 or 48HJ004-014 rooftop units and
provide 2 to 121/2 tons of cooling capacity
with the capability to pre-condition 600 to
3000 cfm of outdoor air.
Indoor-air quality (IAQ) generally refers to the level of pollutants inside a
building. These pollutants include cigarette smoke, carbon dioxide exhaled by
occupants, radon gas, car exhaust, paint
fumes, and odors.
Concern over increased indoor air pollutants has been spurred by several issues:
1) changes in new building construction
methods and retrofit of older buildings
have reduced air infiltration rates; 2) Synthetic materials release airborne particles,
odors, and chemicals; and 3) HVAC systems that bring in minimal fresh air.
In 1989, IAQ concerns caused
ASHRAE to recommend increased ventilation for all public buildings. Simply introducing fresh air into a building, however, is not always practical or cost effective. Additional ventilation can overload
HVAC systems, increase energy costs and
if not properly addressed can increase the
indoor humidity levels.
Carrier’s COBRA energy recovery unit
solves this dilemma by providing increased fresh air while keeping increased
costs to a minimum. In addition, the COBRA energy recovery unit helps reduce
humidity levels, which helps to prevent
deterioration of building materials and retards the growth of mold and mildew. Additionally, the COBRA unit can be combined with the Humidi-MiZer Adaptive
Dehumidification system for maximum
humidity control.
The COBRA energy recovery unit provides the best solution to retaining the energy-conserving benefits of today’s tighter building construction while improving
indoor-air quality.

conditions and cooling load.
Enter cooling capacity table at outdoor entering temperature 95 F, mixed air entering evaporator at 2000 cfm, 76.9
F db, and 65.4 F wb.
The 48HJ006 will provide a total gross cooling capacity
of 59,420 Btuh and sensible cooling of 43,420 Btuh.
Because these values were not at 80 F entering db, they
were calculated based on the notes following the Cooling
Capacity tables.
NOTE: Unit ratings are gross capacities and do not include the effect of evaporator-fan motor heat. To calculate
net capacities see Steps VII and VIII.

From the given find:
External static pressure supply

External static pressure return
0.2 in. wg
Accessory static — None
0.0 in. wg
Total Static
0.8 in. wg
Enter the Fan Performance table for vertical discharge,
standard motor, 48HJ006 at 0.80 in. wg and 2000 cfm.
The rpm is 1326 and bhp is 1.37.
NOTE: Convert bhp to Fan Heat and Watts using the formula found in the note following the Evaporator-Fan Motor Efficiency table on page 214.
For this example:
Watts = (746 x Bhp)/(motor efficiency)
Watts = (746 x 1.37)/(0.74) = 1381 watts
Indoor Fan Heat = watts x 3.413 Btuh/watt
= 1381 x 3.413 = 4713 Btuh
III Select Energy$Recycler device based on outdoor
entering cfm (optional).
Using Energy$Recycler cooling rating tables found in the
Energy$Recycler Product Data choose 62AQ060 unit.
Using 450 cfm outdoor supply airflow, 95 F OD db, and
75 F OD wb find performance of the 62AQ060 at these
conditions:
Energy$Recycler Gross Cooling
Capacity is
13,000 Btuh
Energy$Recycler Gross Sensible
Capacity is
10,100 Btuh
Compressor power is
1.06 kW
Energy$Recycler Leaving db is
73 F
Energy$Recycler Leaving wb is
66.9 F
IV Using the simplified* method below, calculate the
approximate mixed air temperature for the Small
Rooftop (SRT) evaporator coil.
Using the outdoor air entering cfm, the room cfm and the
room exhaust airflow with their respective db and wb
temperatures determine the db and wb entering the rooftop evaporator coil.
a) Estimate the mixed air db to the evaporator coil.
t mix db = ((cfm oa x t oa db) + ((cfm ra – cfm exh) x
t rm db)) / ((cfm oa + (cfm ra – cfm exh)))
= ((450 cfm x 73.0 F) + ((2000 cfm – 450 cfm)
x 78 F)) / ((450 cfm + (2000 cfm – 450 cfm)))
= 76.9 F mixed air into the rooftop evaporator coil
b) Estimate the mixed air wb to the evaporator coil.
t mix wb* = ((cfm oa x t oa wb) + ((cfm ra – cfm exh)
x t rm wb)) / ((cfm oa + (cfm ra – cfm exh)))
= ((450 cfm x 66.9 F) + ((2000 cfm – 450 cfm) x 65
F)) / ((450 cfm + (2000 cfm – 450 cfm)))
= 65.4 F wb mixed air temperature into the rooftop
evaporator
*Simplified method of determining wet bulb (wb)
temperature of mixture. This approximation is used
because the wb lines in the area of the psychrometric
chart used in the calculation is relatively linear, providing a close approximation. A more accurate solution can be found using the
E-Cat program.
VII Select net heating capacity of unit to meet design
condition requirements.
48HJ
Enter the 62AQ060 Heating Rating table found in the Energy$Recycler™ Product Data. At 450 cfm, 70° F and 0°
F find the heating value for the Energy$Recycler device to
be 15.2 Btuh. Since the Energy$Recycler device uses
room air, the instantaneous heat is also the Integrated Heat
Rating.
The customer heat requirement is 85,000 Btuh.

Determine additional electric heat capacity in kW.
The required heating capacity is 85,000 Btuh. Therefore,
65,087 Btuh (85,000 – 19,913) additional heat is required.
The output capacity for the 48HJE006 is 93,150 Btuh,
which is sufficient.
Total unit net heating capacity is 113,063 Btuh (93,150 +
19,913).
VIII Determine net cooling capacity.
Cooling capacities are gross capacities and do not include
indoor (evaporator) or optional Energy$Recycler supply

**The calculated MOCP is 43.1 amps; it is rounded down
to 40 amps. Compare it to MCA; it must be larger than
the MCA of 37.0 amps, so it is acceptable as is.
Selection procedure (with 48HJ006 example) (cont)
The wiring of the unit must be suitable for the MCA calculated above, and the Maximum Overcurrent Protection (MOCP) device must be selected to meet the calculated MOCP.
If the overcurrent protective device for the combination
load is equal to or less than 60 amps, a single disconnect
may be used for BOTH the main unit and the 62AQ unit
provided that the wire ampacity supplying the 62AQ unit
is sized for a minimum of 33% larger than the overcurrent
protection device value (i.e., 60 amps x 0.33 = 20 amps),
no further subfusing would be required.
If the overcurrent protection device is greater than 60
amps and the old overcurrent protection device was less
than 60 amps, a FUSED disconnect no greater than 60
amps must be provided for the main unit and a SEPARATE FUSED disconnect must be provided for the 62AQ
unit.
If the old overcurrent protection device is greater than 60
amps, a disconnect is required for the MAIN UNIT as
well as a FUSED DISCONNECT for the 62AQ unit.

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air
leaving evaporator coil (hlwb)
hlwb = hewb –
total capacity (Btuh)
4.5 x cfm
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.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

— Total Capacity (1000 Btuh) Gross
NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air
leaving evaporator coil (hlwb)
hlwb = hewb –
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.
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:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air
leaving evaporator coil (hlwb)
hlwb = hewb –
total capacity (Btuh)
4.5 x cfm
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.
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:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving evaporator coil (hlwb)
total capacity (Btuh)
hlwb = hewb –
4.5 x cfm
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.

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving evaporator coil (hlwb)
total capacity (Btuh)
hlwb = hewb –
4.5 x cfm
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.

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.

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving evaporator coil (hlwb)
total capacity (Btuh)
hlwb = hewb –
4.5 x cfm
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.

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving evaporator coil (hlwb)
total capacity (Btuh)
hlwb = hewb –
4.5 x cfm
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.

2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air
leaving evaporator coil (hlwb)
hlwb = hewb –
total capacity (Btuh)
4.5 x cfm
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.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air
leaving evaporator coil (hlwb)
hlwb = hewb –
total capacity (Btuh)
4.5 x cfm
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.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

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.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air
leaving evaporator coil (hlwb)
hlwb = hewb –
total capacity (Btuh)
4.5 x cfm
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.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air
leaving evaporator coil (hlwb)
hlwb = hewb –
total capacity (Btuh)
4.5 x cfm
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.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

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
Carrier representative for details.
6. Field-supplied drive requires changing belt and motor pulley to
meet desired air flow. See application data or contact your local
Carrier representative for details.

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 216.
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

*Single phase/3 phase.
NOTES:
1. Convert bhp to watts using the following formula:
bhp (746)
watts =
motor efficiency
48HE/HJ
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 requirements. Therefore, the indoor fan motors for Carrier 48HE003-006 and 48HJ004014 units are exempt from these requirements.

*Derating of the gas heating equipment to compensate for the effects of altitude 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 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.

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.
max voltage deviation from average voltage
= 100 x
average voltage
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
452 + 464 + 455

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.

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 48HJD006---5 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.

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 48HJD006---5 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.

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 48HJD006---5 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.

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

(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

Controls
space at the set point level. The set point is calculated from the
differential air quality that is configured by the user. As air
quality within the space changes, the position of the economizer damper will also change thus allowing more or less outdoor air into the space. If IAQ is configured for low priority, the
positioning of the economizer damper can be overridden by
comfort requirements. If IAQ is configured for high priority,
the controller will check the air quality every 30 seconds and
will perform supply air tempering when in IAQ mode if the following criteria are met:
• IAQ priority is high
• Outdoor temperature is less than 55 F
• Heat and cool set points have not been exceeded
Demand Control Ventilation — Certain criteria must be considered when using the PremierLink™ controller for demand
control ventilation. When selecting the heating and cooling
capacity of the equipment, the maximum ventilation rate must
be evaluated for design conditions along with the maximum
damper position to achieve desired conditioning of the space.
Typical maximum ventilation rate should be ASHRAE occupied design crfm +5 to 10%.
The PremierLink controller can also provide tempering of the
supply air when the space or return air temperature falls between the occupied heat and cool set points or there is not a call
for heating or cooling in the Thermostat mode. The maximum
ventilation airflow rate should be checked by evaluating the
unit’s heating capability to raise the supply air to an acceptable
level during tempering of supply air.
After determining the maximum ventilation airflow rate the
IAQ maximum damper configuration needs to be configured.
Demand control ventilation software may be used to assist in
determining the CO2 maximum ventilation recovery rate. The
recovery rate can be accomplished by using either proportional-anticipatory strategy or proportional integral (PI) control.
PremierLink™ Direct Digital Controls — The PremierLink
Direct Digital Controls (DDC) require the use of a Carrier electronic thermostat or a CCN connection for time broadcast to
initiate its internal timeclock. This is necessary for broadcast of
time of day functions (occupied/unoccupied). Refer to PremierLinkTM literature for more information

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 contactor 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 thermostat 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 mixedair temperature fluctuates above 55 or below 50 F, the dampers
will be modulated (open or close) to bring the mixed-air temperature back within control.
If mechanical cooling is utilized with free cooling, the
outdoor-air damper will maintain its current position at the time
the compressor 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$er IV control, it will
take the damper up to 21/2 minutes before it begins to position
170
itself. Any change in damper position will take up to 30 seconds to initiate. Damper movement from full closed to full
open (or vice versa) will take between 11/2 and 21/2 minutes.
If free cooling can be used as determined from the appropriate changeover command (switch, dry bulb, enthalpy curve,
differential dry bulb, or differential enthalpy), then the control
will modulate the dampers open to maintain the mixed-air temperature set point at 50 to 55 F.
If there is a further demand for cooling (cooling second stage
— Y2 is energized), then the control will bring on compressor
stage 1 to maintain the mixed-air temperature set point. The
EconoMi$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 operation. 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 activation 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,
interrupting 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 indoorfan 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.
Cooling, units with EconoMi$er2, PremierLink Control and
a room sensor — When free cooling is not available, the compressors will be controlled by the PremierLink controller using
a PID Error reduction calculation as indicated below.
The PremierLink controller will use the following information to determine if free cooling is available:
• Indoor fan has been on for at least 30 seconds.
• The SPT, SAT, and OAT inputs must have valid readings.
• OAT must be less than 75 F.
• OAT must be less than SPT.
• Enthalpy must be LOW (may be jumpered if an enthalpy
sensor is not available).
• Economizer position is NOT forced.
When free cooling is available, the outdoor-air damper is positioned through the use of a Proportional Integral (PID) control process to provide a calculated supply-air temperature into
the zone. The supply air will maintain the space temperature
between the heating and cooling set points.
The PremierLink control will integrate the compressors stages with the economizer based on logic built into the controller.
If an 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
PremierLink™ control, a PID-controlled demand 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.
Heating, unit with EconoMi$er2, PremierLink control and
a room sensor — Every 40 seconds the controller will calculate the required heat stages (maximum of 3) to maintain Supply Air Temperature (SAT) if the following qualifying
conditions are met:
• Indoor fan has been on for at least 30 seconds.
• COOL mode is not active.
• OCCUPIED, TEMP.COMPENSATED START or HEAT
mode is active.
• SAT reading is available.
• Fire shutdown mode is not active.
If all of the above conditions are met, the number of heat
stages is calculated; otherwise the required number of heat
stages will be set to 0.
If the PremierLink controller determines that heat stages are
required, the economizer damper will be moved to minimum
position if occupied and closed if unoccupied.

When the thermostat is satisfied and W1 and W2 are deenergized, the IFM continues to run and the economizer damper
then moves to the minimum position.
Cooling, units with EconoMi$er2, PremierLink™ control
and a thermostat — When free cooling is not available, the
compressors will be controlled by the PremierLink control in
response to the Y1 and Y2 inputs from the thermostat.
The PremierLink control will use the following information
to determine if free cooling is available:
• Indoor fan has been on for at least 30 seconds.
• The SPT, SAT, and OAT inputs must have valid readings.
• OAT must be less than 75 F.
• OAT must be less than SPT.
• Enthalpy must be LOW (may be jumpered if an enthalpy
sensor not available).
• Economizer position is NOT forced.
Pre-cooling occurs when the is no call from the thermostat
except G. Pre-cooling is defined as the economizer modulates
to provide 70 F supply air.
When free cooling is available the PremierLink control will
control the compressors and economizer to provide a supply-air
temperature determined to meet the Y1 and Y2 calls from the
thermostat.
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
PremierLink control, a PID-controlled demand ventilation
strategy will begin to operate. As the CO2 level in the zone increases above the CO2 set point, the minimum position of the

Heating, units with EconoMi$er2, PremierLink control and
a thermostat — When the thermostat calls for heating, terminal W1 is energized. The PremierLink control will move the
economizer damper to the minimum position if there is a call
for G and closed if there is a call for W1 without G. In order to
prevent thermostat from short cycling, the unit is locked into
the heating mode for at least 10 minutes when W1 is energized.
The induced-draft motor is then energized and the burner ignition sequence begins.
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 unless G is still maintained.

Operating sequence, COBRA™ energy
recovery units (48HE003-006 and 48HJ004-014)
Cooling, units with COBRA™ energy recovery — The cooling changeover thermostat located on COBRA energy recovery
unit hood determines when the COBRA energy recovery unit
goes into economizer mode. When the outdoor temperature is
below the cooling set point the unit will be in economizer
mode.
In the unoccupied mode, fans are normally set for AUTO
operation, causing the fans to cycle on only as needed for heating or cooling. If the Light Commercial Thermidistat™ device
is set for “AUTO” fan, the rooftop unit fan will be off except
when cooling or humidity control is required. The COBRA
energy recovery unit fans will be off except when unit is running in the economizer mode. If the Light Commercial Thermidistat device is set to “ON” for fan, the COBRA energy
recovery unit and rooftop unit fans will run continuously. If
outdoor air is below the outdoor air thermostat set point, the
compressors are locked off and the unit operates in economizer
mode when cooling is required. If outdoor air is unsuitable due
to humidity or quality, the COBRA energy recovery unit is off
and only the rooftop unit compressor runs when cooling is
required. Note that the COBRA energy recovery unit does not
run and dampers are closed when the outdoor air is unsuitable
for cooling and the mode is unoccupied. If outdoor air is suitable, first stage cooling is COBRA energy recovery unit in
economizer mode and all compressors are off. Second stage
cooling adds the COBRA energy recovery unit compressor and
rooftop unit compressor no. 1.
In occupied mode, when the COBRA energy recovery unit
compressor runs in cooling mode, it is extracting heat from the
incoming outdoor air and rejecting heat to the exhaust air. The
COBRA energy recovery unit and rooftop unit fans run continuously. On a first stage call, all compressors will be off if the
outdoor air is suitable for free cooling. Otherwise, the COBRA
energy recovery unit compressor and rooftop unit compressor
no. 1 will run whenever there is a first stage demand for cooling. On a second stage call, the COBRA energy recovery unit
compressor and rooftop unit compressor no. 1 and 2 will run
whenever there is a demand for cooling. If there is a demand
for humidity control but not cooling, only the COBRA energy
recovery unit compressor will run. If there is a field-installed
CO2 sensor and the levels are below that sensor set point, then
the unit will operate in the unoccupied mode sequence
(i.e.,COBRA energy recovery unit dampers closed and rooftop
unit operation only to maintain space conditions).
Heating, units with COBRA energy recovery — The heating
changeover thermostat located on the COBRA energy recovery
unit hood determines the stage 1 to stage 2 switchover point in
heating mode.
In unoccupied mode, the COBRA energy recovery unit is off
and all compressors are locked off. First stage heat is rooftop
unit heat at 50%. Second stage heat is rooftop unit heat at
100%.
In unoccupied mode, when the COBRA energy recovery unit
compressor runs in heat mode, it is extracting heat from the
exhaust air and rejecting heat to the incoming outdoor air. So it
is returning energy to the building that otherwise would be
“thrown away”. The COBRA energy recovery unit and rooftop
unit fans run continuously. The rooftop unit compressors are
always off. On a first stage call, the COBRA energy recovery
unit compressor is on in heat mode. Rooftop unit heat is off if
the outdoor air is above the set point. Rooftop unit heat is on at
50% if the outdoor air is below the set point. On a second stage
call, the COBRA energy recovery unit compressor is on in heat
mode. Rooftop unit heat is on a 50% if the outdoor air is above
the set point. Rooftop unit heat is on at 100% if the outdoor air
is below the set point.
Defrost — If the temperature of the 62AQ section condenser
(exhaust air) coil drops below 28 F at the defrost thermostat
(DFT) and the defrost timer is at the end of a timed period (adjustable to 30, 50 or 90 minutes), then the reversing valve solenoid (RVS) is energized and the condenser fan contactor(s) are
deenergized. This switches the position of the reversing valve
and shuts off the 62AQ section condenser (exhaust air) fan. The
unit continues to defrost until the coil temperature measured at
the DFT reaches 65 F or the defrost cycle completes a 10minute cycle. At the end of the defrost cycle the RVS deenergizes and the exhaust fan motor energizes to put the unit in
heating mode. If the space thermostat is satisfied during a defrost cycle, then the 62AQ section will continue in the Defrost
mode until the defrost cycle is complete.

air temperature fluctuates above 55 or below 50 F, the dampers
will be modulated (open or close) to bring the mixed-air temperature back within control.
If mechanical cooling is utilized with free cooling, the
outdoor-air damper will maintain its current position at the time
the compressor 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$er IV control, it will
take the damper up to 21/2 minutes before it begins to position
itself. Any change in damper position will take up to 30 seconds to initiate. Damper movement from full closed to full
open (or vice versa) will take between 11/2 and 21/2 minutes.
If free cooling can be used as determined from the appropriate changeover command (switch, dry bulb, enthalpy curve,
differential dry bulb, or differential enthalpy), then the control
will modulate the dampers open to maintain the mixed-air temperature set point at 50 to 55 F.
If there is a further demand for cooling (cooling second stage
— Y2 is energized), then the control will bring on compressor
stage 1 to maintain the mixed-air temperature set point. The
EconoMi$er IV damper will be open at maximum position.
EconoMi$er IV operation is limited to a single compressor.

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

a 50 to 55 F mixed-air temperature into the zone. As the mixedair temperature fluctuates above 55 or below 50 F, the dampers
will be modulated (open or close) to bring the mixed-air temperature back within control.
If mechanical cooling is utilized with free cooling, the
outdoor-air damper will maintain its current position at the time
the compressor 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$er IV control, it will
take the damper up to 21/2 minutes before it begins to position
itself. Any change in damper position will take up to 30 seconds to initiate. Damper movement from full closed to full
open (or vice versa) will take between 11/2 and 21/2 minutes.
If free cooling can be used as determined from the appropriate changeover command (switch, dry bulb, enthalpy curve,
differential dry bulb, or differential enthalpy), then the control
will modulate the dampers open to maintain the mixed-air temperature set point at 50 to 55 F.
If there is a further demand for cooling (cooling second
stage — Y2 is energized), then the control will bring on compressor stage 1 to maintain the mixed-air temperature set point.
The EconoMi$er IV damper will be open at maximum posi-

tion. 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 operation. 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 activation 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
176
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,
interrupting 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 indoorfan 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.
When the thermostat is satisfied and W1 and W2 are deenergized, the IFM continues to run and the economizer damper
then moves to the minimum position.
Application data
Condensate drain pan
High altitudes
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.
These may require a change to the gas orifice. Refer to
tude Compensation tables.
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. Field-supplied flanges can be attached to horizontal discharge openings and all ductwork attached to flanges.
Thermostat
Use of 2-stage cooling thermostat is recommended for all units
equipped with economizer. A 2-stage cooling thermostat is required for size 015-028 units with integrated economizer.
Heating-to-cooling changeover
All units are automatic changeover from heating to cooling
when automatic changeover thermostat and subbase are used.
Airflow
Alti-
Minimum heating entering air temperature
The minimum temperature of air entering the dimpled heat exchanger is 50 F continuous and 45 F intermittent for aluminum
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 temperature 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 setting 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 initiated using
low entering air temperatures with insufficient heating temperature rise.
Units are draw-thru on cooling and blow-thru on heating.
Maximum airflow
To minimize possibility of condensate blow-off from evaporator, airflow through units should not exceed 500 cfm/ton (sizes
004-025) and 11,250 cfm (size 028).
WIRING OF OUTDOOR-AIR THERMOSTAT
Minimum airflow
Minimum airflow for cooling is 300 cfm/ton (size 004-025) and

Due to Carrier’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 Carrier 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.
Carrier PremierLink™ controls
The Carrier PremierLink controls can be used with any thermostat.
Thru-the-bottom connections
The accessory thru-the-bottom connections are needed to ensure proper connections when routing wiring and piping
through the basep an 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.
177
48HE/HJ
Minimum ambient operating temperature for size 004-014 standard units is 25 F. With accessory Motormaster® I, II, or IV units
can operate at outdoor temperatures down to –20 F.
Unit sizes 015-028 are designed to operate at outdoor temperatures down to 40 F. With accessory Motormaster I or Motormaster V control, units can operate at outdoor temperatures
down to –20 F.
NOTE: Under most application circumstances, if the rooftop
unit is equipped with an economizer, low ambient controls 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.

Condenser coil protection
Pre-coated aluminum-fin coils have a durable epoxyphenolic coating applied to the fin prior to the fin stamping process
to provide protection in mildly corrosive 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 protection beyond the standard uncoated coil construction.
Copper-fin coils provide increased corrosion resistance in
moderate coastal environments where industrial air pollution is
not present. All copper coils eliminate bi-metallic construction
to eliminate the potential for galvanic 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
compared to standard or pre-coated aluminum-fin coils.
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 previous post coating processes. E-Coated
aluminum-fin coils offer economical protection and improved
coil life in many contaminated environments.
E-Coated copper-fin coils provide maximum protection in
virtually all environments, this option combines the continuous, impenetrable barrier of the E-Coating process with the natural resistance of an all-copper construction. E-Coated copperfin coil assemblies ensure long life, even in environments that
combine harsh coastal conditions with industrial contamination.

EconoMi$er IV
When used, an IAQ sensor will modulate the damper from the
minimum position (base ventilation rate based on CO2 levels)
to maximum position (full occupancy ventilation rate).
Damper operation — The EconoMi$er IV allows the damper to
be configured for two adjustable damper positions including
maximum position and occupied minimum positions. The two
(2) position damper capability is a unique feature of
EconoMi$er IV and includes operation flexibility as follows:
1. Minimum Occupied Position: This adjustable position
allows a minimum ventilation (base ventilation rate) airflow rate through the unit during occupied periods.
2. Demand Control Ventilation (DCV) Maximum Position:
A DCV maximum occupied position is provided when
using an IAQ sensor for DCV. See DCV and Control sections for sequence. The DCV Maximum Position limits
outdoor airflow into the rooftop when the DCV routine
overrides the mixed air sensor. Setting the DCV Maximum Position of the outdoor air damper prevents large
amounts of hot or cold air into the space.
IMPORTANT: When the DCV Maximum Position is set
below the minimum position, the minimum position overrides the maximum position, negating most DCV functions.
Power exhaust — The EconoMi$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$er IV is an integrated
economizer and has the ability to utilize simultaneous outdoor
air and compressors. The EconoMi$er IV can be configured to
support economizer and compressor operation. Only one or
two compressor operation is available with 3 to 121/2 ton units.
Changeover strategies — The EconoMi$er IV controller can
be configured to accommodate all available economizer control
strategies that place the rooftop unit in economizer mode including:
Remote Minimum Position — Used when a remote signal from
a remote minimum position control will enable and disable the
EconoMi$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$er
IV Changeover diagram below. The A, B, C, and D curves
shown have been in use for many years and have been included
as part of the latest ASHRAE 90.1 energy efficiency code. The
curves are designed to take into consideration both outdoor
temperature and humidity. These curves are used to set up the
EconoMi$er IV controller to use the EconoMi$er IV for free
cooling when the conditions to the left of the curve exist. When
the conditions are to the right of the curve, then outdoor air
cooling will not be used and the outdoor air damper position
will be set at the minimum position.
179
48HJ
The EconoMi$er IV factory-installed economizer package includes a gear-driven damper system 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$er IV microprocessor-based controller optimizes
and enhances rooftop operation through reduced energy consumption, optimal zone comfort, and efficient equipment cycling. This is accomplished by operating the compressors when
the outdoor air temperature is too warm, integrating the compressors with outdoor air when free cooling is available, and
locking out the compressor when outdoor air temperature is too
cold. The detailed sequence of operation is described in the
Controls section with a brief description of selected application
items here.
Thermostat interface — The EconoMi$er IV control 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 addition, the EconoMi$er IV will
support an occupied/unoccupied switch (typically integrated
into the thermostat or Thermidistat™ device). When the switch
is closed, it provides a 24-vac signal to the unit for occupied
mode, and provides no signal to indicate unoccupied mode.
The EconoMi$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.
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$er IV controller
can be used with a field-supplied and field-installed remote
minimum position control switch that will enable and disable
the EconoMi$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 ventilation 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$er IV can be utilized with any IAQ
(CO2) sensor that provides a 2 to 10 vdc output. The controller
will modulate the outdoor air damper to provide ventilation
based on the sensor output and the IAQ setting of the controller.
Application data (cont)
tentially be undesirable since the temperature and humidity levels are too high without compression assistance to provide effective cooling. Therefore, most changeover economizers utilize the D curve.
Differential enthalpy — The EconoMi$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 economizer 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.
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 diagram 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 po-
