FEATURES/BENEFITS
Every compact one-piece unit arrives fully assembled,
charged, tested, and ready to run.
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 090-180 offer lower utility costs through part-load
operation using 2 stages of cooling.
Quiet and efficient operation is provided by belt-driven indoor
fans (standard on all units over 5 tons). The belt-driven indoor
fan is equipped with variable-pitch pulleys which allow adjustment within the rpm ranges of the factory-supplied pulleys.
Increased operating efficiency is achieved through computerdesigned coils featuring staggered internally enhanced copper
tubes. Fins are ripple-edged for strength, lanced, and double
waved for higher heat transfer.
Form No. PDS 548F.36.4
TABLE OF CONTENTS
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.
To Convert 036-120 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
jobsite.
To Convert 150,180 Units from vertical to horizontal discharge,
use the optional horizontal supply/return adapter roof curb.
Convenient Duct Openings in the unit basepans permit sideby-side or concentric duct connections (see Application Data
section) without requiring internal unit modification (150,180
only).
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 to be
routed through the unit’s basepan, thereby minimizing roof penetrations (to prevent water leaks). Power and control connections are made on the same side of the unit to simplify
installation.
The Non-Corrosive Sloped Condensate Drain Pan 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.
All 036-120 Units are Designed with a Single, Continuous
Top Piece to eliminate leaking at the seams or gasketing.
Belt-Driven Indoor-Fan Motors allow maximum on-site flexibility without changing motors or drives.
Field-Installed Accessory Electric heaters are available in a
wide range of capacities. An available single-point wiring kit
makes installation simple.
Low Voltage Wiring Connections are easily made due 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. Bryantspecified hermetic compressors are equipped with compressor
overcurrent and overtemperature protection to ensure
dependability.
All units have a fixed-orifice (036-120) or TXV metering
device (150,180) which precisely controls refrigerant flow, preventing slugging and flood-back, while maintaining optimum unit
performance. Refrigerant filter driers are standard.
Standard Low Ambient Cooling Operation to 25 F (036-120)
or 40 F (150,180); optional head pressure control kit available
for outdoor ambient conditions to –20 F.

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 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 036-120 units are designed with a single,
continuous top piece to eliminate any possible leaks. Totally
enclosed condenser-fan motors and permanently lubricated
bearings provide additional unit dependability.
Patented State-of-the-Art Chronotemp™ Defrost System
uses time and temperature to keep the outdoor coil frost-free for
economical, dependable operation. The Chronotemp defrost
board can be easily configured for defrost cycles every 30, 50, or
90 minutes.
Dependable 4-Way Valve Operation safely and efficiently
accomplishes cycle reversals, defrost, and normal operation.
EASY INSTALLATION AND CONVERSION
All Units are Shipped in the Vertical Duct Configuration for
fit-up to standard roof curbs. (3 different curb sizes fit unit sizes
036-072, 090-120, 150 and 180 respectively.) The contractor
can order and install the roof curb early in the construction
stage, before decisions on size requirements are made.

INTEGRATED ECONOMI$ERS AND OUTDOOR AIR
Optional EconoMi$ers 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
discharge-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 stays
at vent position.
Accessory upgrade kits allow for either outdoor air enthaply
changeover or for more precise differential enthalpy control.
Units can also utilize the factory or field-installed EconoMi$er.
The EconoMi$er is microprocessor controlled and incorporates
a parallel, opposed-blade gear driven damper system. In addition, it has a spring return built into the damper actuator to provide reliable close-on-power-loss. The EconoMi$er comes
equipped with up to 90% barometric relief capability for high
outdoor airflow applications on 036-120 units only. Optional
field-installed Barometric Relief package is available for use on
150,180 size units.
In addition, the EconoMi$er two-stage power exhaust accessory can be utilized to help maintain proper building pressure
(036-120 units only). Single stage power exhaust is available for
unit sizes 150,180 as a field-installed accessory.
For units without economizer, year-round ventilation is
enhanced by a manual outdoor-air damper. On 036-120 units, a
25% or 50% manual damper is available as a field-installed
accessory. Unit sizes 150,180 are equipped with a standard
manual 25% damper.
SERVICE OPTIONS
Servicing a rooftop unit has never been easier with the new
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, indoor 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. Simply 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.
INDOOR-AIR QUALITY BEGINS WITH BRYANT ROOFTOPS
Sloped condensate pans minimize biological growth in rooftop
units in accordance with ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engineers) Standard
62. Two-inch filters with optional dirty filter indicator switch provide for greater particle reduction in the return air. The face-split
evaporator coils improve the dehumidification capability of standard units, maximize building humidity control.

CONTROLS
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 EconoMi$er damper is maintained at its current
position.
2. If Y1 is energized for more than 20 minutes, and Y2 is not
energized (whether or not a 2-stage thermostat is used),
the compressor and OFM are energized. The EconoMi$er
damper is maintained at its current position.
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 compressor is energized and the thermostat is satisfied,
the compressor, the OFM, and IFM are deenergized and
the EconoMi$er modulates closed.
When the OAT is below the MECH CLG LOCKOUT set point,
the compressors remain off.
Cooling, Units With EconoMi$er (548F090-120 and
549B090,120) — 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-fan motor (IFM)
is energized and the EconoMi$er damper modulates to minimum position. The compressor contactor is energized to start
the compressor and outdoor-fan motor (OFM) and RVS1
(reversing valve solenoid). After the thermostat is satisfied, the
damper modulates to the fully closed position when the IFM is
deenergized.
When the OAT is below the ECON SP setting and the room
thermostat calls for Stage 1 cooling (R to G + Y1), the
EconoMi$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: Compressors have 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), compressor no. 1 and OFM are energized. The EconoMi$er damper is maintained at its current
position.
2. If Y1 is energized for more than 20 minutes, and Y2 is not
energized (whether or not a 2-stage thermostat is used),
compressor no. 1 and OFM are energized. The EconoMi$er
damper is maintained at its current position.
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
energized.
OPERATING SEQUENCE — 548F036-120 AND 549B036-120
Cooling, Units Without Economizer — When thermostat calls
for cooling, terminals G and Y1 are energized. The indoor-fan
contactor (IFC), reversing valve solenoid (RVS1) and compressor contactor no. 1 (C1) are energized and indoor-fan motor,
compressor no. 1, and outdoor fans start. The outdoor-fan
motor(s) run continuously while unit is cooling. On 548F090120 units, if the thermostat calls for a second stage of cooling
by energizing Y2, compressor contactor no. 2 (C2) and reversing valve solenoid (RVS2) are energized and compressor no. 2
starts.
Heating, Units Without Economizer (548F036-072 and
549B036-072) — Set system switch at AUTO. or HEAT position.
Set thermostat at desired temperature.
When the thermostat calls for heat, the IFC, outdoor-fan contactor (OFC), and compressor contactor are energized. The
RVS is deenergized and switches position, and the indoor fan,
outdoor fan, and compressor are energized.
If the thermostat calls for a second stage of heat, the heater
contactor (HC) is energized and starts the electric heaters.
When the space temperature approaches the heating temperature set point, heating stages cycle off. The reversing valve
solenoid is reenergized.
Heating, Units Without Economizer (548F090-120 and
549B090,120) — Upon a request for heating from the space
thermostat, terminal W1 will be energized with 24 v. The IFC,
outdoor-fan contactor (OFC), C1, and C2 will be energized. The
reversing valves switch position and the indoor fan, outdoor fan,
compressor no. 1, and compressor no. 2 are energized.
If the space temperature continues to fall while W1 is energized, W2 will be energized with 24 v, and the heater contactor(s) (HC) will be energized, which will energize the electric
heater(s).
When the space thermostat is satisfied, W2 will be deenergized first, and the electric heater(s) will be deenergized.
Upon a further rise in space temperature, W1 will be deenergized, and the reversing valve solenoids (RVS1 and RVS2) will
be energized.
Cooling, Units With EconoMi$er (548F036-072 and 549B036072) — When the outdoor-air temperature (OAT) is above the
ECON SP set point and the room thermostat calls for Stage 1
cooling (R to G + Y1), the indoor-fan motor (IFM) is energized
and the EconoMi$er damper modulates to minimum position.
The compressor contactor is energized to start the compressor
and outdoor-fan motor (OFM) and RVS1 (reversing valve solenoid). 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$er integrates free cooling
10
CONTROLS (cont)
NOTE: Compressor no. 2 cannot be energized unless there is a
signal for Y2 from the space thermostat.
4. If compressor no. 2 is energized, and the Y2 signal from the
thermostat is satisfied, compressor no. 1 and 2 are deenergized. Reasserting Y2 will start compressor no. 1 and (after
a 20-minute interstage delay) compressor 2.
5. If compressor no. 1 is energized and the thermostat is satisfied, compressor no. 1, the OFM, and IFM are deenergized
and the EconoMi$er modulates closed.
Heating, Units With Economizer — Upon a call for heat
through W1, the IFC energizes to start the evaporator fan and
the economizer damper blade opens to the minimum position. If
the accessory two-position damper is used, the outdoor-air
damper opens to the minimum position whenever the evaporator fan runs. If unit is equipped with 2 stages of heat, when additional heat is needed a call is made through W2.
As space temperature approaches the heating temperature
set point, heating stages cycle off. Economizer or two-position
damper returns to fully closed position.
Defrost (548F036-072 and 549B036-072) — As frost builds up
on the outdoor coil, the coil temperature drops below 28 F.
When this outdoor-coil temperature drop is sensed by the
defrost thermostat (DFT) and the defrost timer is at the end of a
timed period (adjustable at 30, 50, or 90 minutes), the unit operates in a defrost cycle controlled by the defrost timer and thermostat. During this cycle, the reversing valve solenoid (RVS) is
energized and the outdoor fan shuts off. The electric heaters (if
installed) will be energized.
The unit continues to defrost until the coil temperature as
measured by DFT reaches 65 F, or the duration of defrost cycle
completes a 10-minute period.
At the end of the defrost cycle, the electric heaters (if
installed) and the reversing valve will be deenergized, and the
outdoor-fan motor will be energized. The unit will now operate in
the Heating mode.
If the thermostat is satisfied during a defrost cycle, the unit
will continue in the Defrost mode until the time or temperature
constraints are satisfied.
Defrost (548F090-120 and 549B090,120) — When the temperature of the outdoor coil drops below 28 F as sensed by the
defrost thermostat (DFT2) and the defrost timer is at the end of
a timed period (adjustable at 30, 50, or 90 minutes), reversing
valve solenoids (RVS1 and RVS2) are energized and the OFC
is deenergized. This switches the position of the reversing
valves and shuts off the outdoor fan. The electric heaters (if
installed) will be energized.
The unit continues to defrost until the coil temperature as
measured by DFT2 reaches 65 F, or the duration of defrost
cycle completes a 10-minute period.
During the Defrost mode, if circuit 1 defrosts first, RVS1 will
oscillate between Heating and Cooling modes until the Defrost
mode is complete.
At the end of the defrost cycle, the electric heaters (if
installed) will be deenergized; the reversing valves switch and
the outdoor-fan motor will be energized. The unit will now operate in the Heating mode.
If the space thermostat is satisfied during a defrost cycle, the
unit will continue in the Defrost mode until the time or temperature constraints are satisfied.
SEQUENCE OF OPERATION — 542J150,180
Cooling, Units Without Economizer — With unit main power
on, set thermostat to COOL position and desired room temperature. Set fan switch at AUTO. (on demand) or ON (continuous)
position.
On a rise in room temperature, cooling contactor no. 1 in the
thermostat closes. The indoor and outdoor fan motors start. If
the 5-minute compressor time-delay (CTD) on the defrost board
(DB) is satisfied, then compressor no. 1 (542J180) or unloaded
compressor (542J150) contactor is energized and compressor
will start. Compressor cycles on demand of the thermostat to
satisfy room conditions. Each time the cooling contactor no. 1
opens, the CTD starts the 5-minute delay.
On 542J180 units, with an additional rise in room temperature, cooling contactor no. 2 in the thermostat closes, energizing compressor contactor no. 2. Compressor no. 2 starts and
cycles on demand of the thermostat to satisfy the occupied
space demands.
On 542J150 units, compressor runs fully loaded on a call for
second-stage cooling.
Cooling, Units With EconoMi$er — Upon a call for cooling,
when outdoor ambient temperature is above the temperature
control setting, the indoor and outdoor fans and compressor(s)
energize. The economizer damper moves to vent position.
Upon a first-stage call for cooling, when outdoor ambient temperature is below the temperature control setting, the indoor fan
starts and economizer damper modulates to maintain mixed-air
temperature. The compressor(s) remains off.
Upon a second-stage call for cooling, compressor no. 1
(542J180) or loaded compressor (542J150) is energized and
mechanical cooling is integrated with economizer cooling. Compressor no. 2 (542J180) is locked out. If the air temperature is
below 50 F, a cooling lockout switch prevents the compressor(s)
from running.
When supply-air temperature drops below a fixed set point,
the economizer damper modulates to maintain the temperature
at the fixed set point.
A freeze protection thermostat (FPT) is located on the indoor
coil. It detects frost build-up and turns off the compressor(s),
allowing the coil to clear. Once frost has melted, the compressor can be reenergized.

CONTROLS (cont)
Heating, Units Without Economizer — With unit main power
on, set thermostat at HEAT position and desired room temperature. Set fan switch at AUTO. (on demand) or ON (continuous)
position.
On a drop in room temperature, heating contactor no. 1 in the
thermostat closes, energizing heat relay (HR), reversing valve
relay (RVR), reversing valve solenoids (RVS1 and RVS2) and
compressor no. 2 contactor. Compressor (542J150) or compressor no. 2 (542J180) and indoor and outdoor fan motors
start. If the 5-minute CTD on the DB is satisfied, then compressor no. 1 contactor is energized and compressor no. 1 will start.
On units equipped with electric heat, when additional heat is
needed, heating contactor no. 2 in the thermostat closes, energizing W2.
Heating, Units With EconoMi$er — With unit main power on,
set thermostat at HEAT position and desired room temperature.
Set fan switch at AUTO. (on demand) or ON (continuous)
position.
On a drop in room temperature, heating contactor no. 1 in the
thermostat closes, energizing heat relay (HR), reversing valve
relay (RVR), reversing valve solenoids (RVS1 and RVS2) and
compressor no. 2 contactor. Compressor no. 2 (542J180) and
indoor and outdoor fan motors start. If the 5-minute CTD on the
DB is satisfied, then compressor (542J150) or compressor no. 1
(542J180) contactor is energized and compressor (542J150) or
compressor no. 1 (542J180) will start. The outdoor-air damper
stays at vent position while the indoor fan is operating.
On units equipped with electric heat, when additional heat is
needed, heating contactor no. 2 in the thermostat closes, energizing W2.
Defrost Cycle — When the temperature of the outdoor coil
drops below 28 F as sensed by the defrost thermostat (DFT1 or
DFT2), the defrost timer starts. At the end of a timed period
(field set at 30, 50, or 90 minutes), the defrost cycle will begin.
The defrost board energizes terminals O and W2, energizes the
defrost relay (DR), deenergizes the reversing valve solenoids
(RVS1 and RVS2), and energizes the electric heat. The outdoorfan motor will stop.
The unit continues to defrost either until the coil temperature as
measured by DFT1 or DFT2 reaches 65 F, or until unit completes a 10-minute defrost cycle.
During the defrost mode, when a circuit defrosts, RVS will oscillate between heating and cooling modes until defrost mode is
complete. This will prevent the head pressure from getting too
high.
At the end of the defrost cycle, the electric heaters (if applicable) will be deenergized, the reversing valve solenoids will be
energized, and the outdoor fans will start.
Automatic Changeover — When the system selection switch
is set at AUTO. position, unit automatically changes from heating operation to cooling operation when the temperature of the
conditioned space rises to the cooling level setting. When the
temperature of the conditioned space falls to the heating level
setting, unit automatically changes from cooling to heating
operation (with a 3 F deadband in between).
Continuous Air Circulation — Turn unit power on. Set system
control at OFF position. Set fan switch at ON position. The
indoor-fan contactor is energized through the thermostat switch
and the indoor fan runs continuously.
Cycle-LOC™ Protection — If unit operation is interrupted by
an open high-pressure switch, low-pressure switch, indoor coil
freezestat, or by compressor internal line-break device (overcurrent or overtemperature), and compressor is calling for either
cooling or heating, Cycle-LOC protection device simultaneously
locks out unit and lights a warning light on the thermostat.
Restart the unit by manually turning thermostat to OFF and
then to ON position. If any of the protective devices opens
again, the unit continues to lock out until corrective action is
taken.
NOTE: If the unit fails to operate due to compressor overcurrent condition, restart by manually resetting circuit breakers
at the unit. Restart cannot be accomplished at the room
thermostat.
Emergency Heat — If compressor is inoperative due to a
tripped safety device (high or low pressure, indoor coil freezestat, overcurrent, or overtemperature), the Cycle-LOC device
locks out the compressor and lights a warning light on the room
thermostat. When the switch is on (thermostat is set to the EM
HT position), compressor circuit and outdoor thermostats are
bypassed, and the second stage of thermostat energizes the
indoor blower and the electric resistance heaters.

Enter the Fan Performance table for 548F048 vertical discharge. At 1600 cfm and 230-v high speed, the standard
motor will deliver 0.76 in. wg static pressure, 723 watts,
and 0.64 brake horsepower (bhp). This will adequately
handle job requirements.
V DETERMINE NET CAPACITIES.
Capacities are gross and do not include the effect of
indoor-fan motor (IFM) heat.
Determine net cooling capacity as follows:
Net capacity = Total capacity – IFM heat
= 49,900 Btuh – (723 Watts x 3.413
Btuh/Watts)
= 49,900 Btuh – 2468 Btuh
= 47,432
Net sensible capacity = 33,900 Btuh – 2468 Btuh
= 31,432 Btuh
Integrated heating capacity is maximum (instantaneous)
capacity less the effect of frost on the outdoor coil and the
heat required to defrost it. Therefore, net capacity is equal
to 38,410 Btuh, the total heating capacity determined in
Step III.
= 5.0 kW of heat required.
25
50TFQ004-012
548F036-120
Enter the Electric Heating Capacities table (page 54) for
548F048 at 208/230, 3 phase. The 6.5-kW heater at
240 v most closely satisfies the heating required. To calculate kW at 230 v, use the Multiplication Factors table.
6.5 kW x .92 = 5.98 kW
6.5 kW x .92 x 3413 = 20,410 Btuh
Total unit heating capacity is 38,410 Btuh (18,000 +
20,410).
IV DETERMINE FAN SPEED AND POWER REQUIREMENTS AT DESIGN CONDITIONS.
Before entering Fan Performance tables, calculate the
total static pressure required based on unit components.
From the given and the Pressure Drop tables, find:

II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Cooling Capacities table at outdoor entering temperature of 95 F, indoor air entering at 1600 cfm and
67 F ewb. The 548F048 unit will provide a total cooling
capacity of 49,900 Btuh and a sensible heat capacity of
33,900 Btuh.
For indoor-air temperature other than 80 F edb, calculate
sensible heat capacity correction, as required, using the
formula found in Note 3 following the cooling capacities
tables.
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.
Enter the Instantaneous and Integrated Heating Ratings
table at 1600 cfm. At 70 F return indoor air and 0° F air
entering outdoor coil, the integrated heating capacity is
18,000 Btuh. (Select integrated heating capacity value
since deductions for outdoor-coil frost and defrosting have
already been made. No correction is required.)
The required heating capacity is 35,000 Btuh. Therefore,
17,000 Btuh (35,000 – 18,000) additional electric heat is
required.
Determine additional electric heat capacity in kW.

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.
*Heaters are field installed only.
†Used to determine minimum disconnect size per NEC.
**Heater capacity (kW) is based on heater voltage of 208 v, 240 v,
480 v, and 575 v. If power distribution voltage to unit varies from rated
heater voltage, heater kW will vary accordingly.
††Fuse or HACR circuit breaker.
***Optional disconnect switch is unavailable.
Determine percent of voltage imbalance.
7
% 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.
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

SELECTION PROCEDURE (WITH 549B048 EXAMPLE)
I DETERMINE COOLING AND HEATING REQUIREMENTS AT DESIGN CONDITIONS.
Given:
Required Cooling Capacity (TC). . . . . . . . . . . 38,000 Btuh
Sensible Heat Capacity (SHC) . . . . . . . . . . . . 24,000 Btuh
Required Heating Capacity. . . . . . . . . . . . . . . 35,000 Btuh
Outdoor Entering-Air Temperature . . . . . . . . . . . . . . . 95 F
Outdoor-Air Winter Design Temperature . . . . . . . . . . 0° F
Indoor-Air Winter Design Temperature . . . . . . . . . . . . 70 F
Indoor Entering-Air
Temperature . . . . . . . . 80 F edb (entering air, dry bulb),
67 F ewb (entering air, wet bulb)
Indoor-Air Quantity . . . . . . . . . . . . . . . . . . . . . . . 1600 cfm
External Static Pressure . . . . . . . . . . . . . . . . . . 0.45 in. wg
Electrical Characteristics (V-Ph-Hz) . . . . . . . . . . 230-3-60
II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Cooling Capacities table at outdoor entering temperature of 95 F, indoor air entering at 1600 cfm and 67 F
ewb. The 549B048 unit will provide a total cooling
capacity of 47,400 Btuh and a sensible heat capacity of
32,800 Btuh.
For indoor-air temperature other than 80 F edb, calculate
sensible heat capacity correction, as required, using the
formula found in Note 3 following the cooling capacities
tables.
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.
Enter the Instantaneous and Integrated Heating Ratings
table at 1600 cfm. At 70 F return indoor air and 0° F air
entering outdoor coil, the integrated heating capacity is
20,400 Btuh. (Select integrated heating capacity value
since deductions for outdoor-coil frost and defrosting have
already been made. No correction is required.)
The required heating capacity is 35,000 Btuh. Therefore,
14,600 Btuh (35,000 – 20,400) additional electric heat is
required.
Determine additional electric heat capacity in kW.
14,600 Btuh
3413 Btuh/kW
= 4.3 kW of heat required.
Enter the Electric Heating Capacities table for 549B048 at
208/230, 3 phase. The 6.5-kW heater at 240 v most
closely satisfies the heating required. To calculate kW at
230 v, use the Multiplication Factors table.
6.5 kW x .92 = 5.98 kW
6.5 kW x .92 x 3413 = 20,410 Btuh
Total unit heating capacity is 40,810 Btuh (20,400 +
20,410).

IV DETERMINE FAN SPEED AND POWER REQUIREMENTS AT DESIGN CONDITIONS.
Before entering Fan Performance tables, calculate the
total static pressure required based on unit components.
From the given and the Pressure Drop tables, find:
External static pressure
.45 in. wg
Durablade economizer
.05 in. wg
Electric heat
.09 in. wg
Total static pressure
.59 in. wg
Enter the Fan Performance table for 549B048 vertical discharge. At 1600 cfm and 230-v, the standard motor will
deliver 1.2 in. wg static pressure and 1.15 brake horsepower (bhp). This will adequately handle job requirements.
NOTE: Convert bhp to Watts using the formula below and
the motor efficiency found in the Indoor-Fan Motor Data
table.
For this example:
746 x Bhp
Watts =
Motor Efficiency
Watts =
746 x 1.15
.75
Watts = 1144
V DETERMINE NET CAPACITIES.
Capacities are gross and do not include the effect of
indoor-fan motor (IFM) heat.
Determine net cooling capacity as follows:
Net capacity = Total capacity – IFM heat
= 47,400 Btuh – (1144 Watts x 3.413
Btuh/Watts)
= 47,400 Btuh – 3904 Btuh
= 43,496
Net sensible capacity = 32,800 Btuh – 3904 Btuh
= 28,896 Btuh
Integrated heating capacity is maximum (instantaneous)
capacity less the effect of frost on the outdoor coil and the
heat required to defrost it. Therefore, net capacity is equal
to 40,810 Btuh, the total heating capacity determined in
Step III.

Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
*Used to determine minimum disconnect per NEC.
†Heater capacity (kW) is based on heater voltage of 208 v and 480 v. If
power distribution voltage to unit varies from rated heater voltage,
heater kW will vary accordingly.
**Fuse or HACR circuit breaker.
††Optional disconnect switch cannot be used.
***Units have 2 outdoor fan motors.
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
7
% 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.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load and 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.

II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Cooling Capacity table on page 109 at outdoorentering temperature of 95 F, indoor air entering at
6000 cfm and 67 F ewb. The 542J180 will provide a total
capacity (TC) of 180,800 Btuh, a sensible heat capacity
(SHC) of 136,400 Btuh and a total unit kW of 15.88.
For indoor-air temperature other than 80 F edb, calculate
sensible heat capacity correction, as required, using the
formula found in Note 3 following the Cooling Capacities
table on page 109.
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.
Enter the Integrated Heating Capacities table on page 110
at 6000 cfm. At 70 F return indoor air and 0° F air entering
the outdoor coil, the integrated heating capacity is
58,500 Btuh with a unit input kW of 11.71 (interpolation
required).
The required heating capacity is 170,000 Btuh; therefore,
111,500 Btuh (170,000 – 58,500) additional electric heat is
necessary.
Determine the additional electric heat capacity in kW.

speed is 1214 and the bhp is 3.95 (interpolation required).
The standard motor and alternate high static drive are
suitable.
V DETERMINE NET CAPACITIES.
Capacities are gross and do not include the effect of
indoor-fan motor (IFM) heat.
Determine net cooling capacity as follows:
Net capacity = Gross capacity – IFM heat
2545 Btuh
hp
= 180,800 – 3.95 bhp x
.85
= 180,800 – 11,827
= 168,973 Btuh
Net sensible capacity = 136,400 – 11,827
= 124,573 Btuh
Determine net heating capacity as follows:
Net capacity =
Gross capacity + IFM heat + Electric heat capacity
= 58,500 + (IFM kW x 3412) + (Elec. kW x 3412)
= 58,500 + 11,827 + (34 x 3412)
= 58,500 + 11,827 + 116,008
= 186,335 Btuh
