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.

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 024-120 units are designed with a sing le, continuous top piece to eliminate any possible leaks. Totally enclosed outdoor-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 eve ry 30, 50, or 90 minutes.
Dependable 4-Way Valve Operation safely and efficiently accomplishes cycle reversals, defrost, and normal operation.
EASY INST ALLATION 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 024-072, 090-120, and 150,180 respectively.) 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.
T o Convert 024-120 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 Size 150 and 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 (size 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 024-120 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 flexi-
bility 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. Bryant-specified hermetic compressors are equipped with compressor overcurrent and overtemperature protection to ensure dependability.
All units have a fixed orifice metering device 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; optional head pressure control kit available for outdoor ambient con di­tions to –20 F.

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$erIV and EconoMi$er2 are available. The EconoMi$erIV is used with the standard rooftop unit controls and includes an industry standard, stand-alone, solid­state control. The control can be used with a CO
sensor for
2
DCV (demand control ventilation) operation. For direct digital control (DDC) applications, the EconoMi$er2 can be operated using a third party controller. The EconoMi$er2 includes 4 to 20 mA actuator capability for demand control ventilation applications.
All economizers incorporate a parallel blade, gear driven damper system for efficient air mixing and reliable control. In addition, the standard damper actuator includes a spring return to provide reliable closure on power loss. The economi zers for sizes 024-120 are equipped with up to 100% barometric relief capability for high outdoor airflow operations. Economizers for unit sizes 024-120 are available, factory-installed, for vertical return only. Economizers for unit sizes 150 and 180 are compat­ible for vertical or horizontal return. An optional field-installed barometric relief package is available for 150 and 180 size units.
In addition, single-stage power exhaust is available as a field­installed accessory for EconoMi$erIV to help maintain proper building pressure.
For units without economizer, year-round ventilation is enhanced by a manual outdoor-air damper. On size 024-120 units, a 25% or 50% manual damper is available as a field­installed accessory. Unit sizes 150 and 180 are equipped with a 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 (549B, 549C and 542J only) 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 wind­blown 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 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 CO
sensor is available with the
2
EconoMi$erIV outdoor air damper option/accessory to aid the IAQ benefits.

Sensible Heat Capacity (SHC) . . . . . . . . . . . . 24,000 Btuh
Required Heating Capacity. . . . . . . . . . . . . . . 35,000 Btuh
Outdoor Entering-Air Temperature db. . . . . . . . . . . . . 95 F

Indoor-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 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.
Enter the Electric Heating Capacities table (page 52) 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 REQUIRE-
MENTS 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 EconoMi$erIV .07 in. wg Electric heat .09 in. wg Total static pressure .61 in. wg
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.
17,000 Btuh
3413 Btuh/kW
= 5.0 kW of heat required.

GENERAL FAN PERFORMANCE NOTES
1. Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with confidence. Using your fan motors up to the wattage ratings shown will not result in nui­sance tripping or premature motor failure. Unit warranty will not be affected. For additional information on motor performance, refer to Indoor Fan Motor Performance table on page 54.
2. Values include losses for filters, unit casing, and wet coils. See Accessory/FIOP Static Pressure tables on page 50 for accessory static pressure information.
3. Use of a field-supplied motor may affect wire sizing. Contact your Bryant representative for details.
4. Interpolation is permissible. Do not extrapolate.

*Two heater packages required to provide kW indicated.
†Use CRSINGLE004A00 for units with convenience outlet.
**Use CRSINGLE002A00 for units with convenience outlet.
††Use CRSINGLE002A00 for units with high-static motor and convenience outlet.
NOTES:
1. The rated heater voltage is 240, 480, and 575 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.
2. To determine heater kW at voltages other than those shown in table, use the following formula: Heater kW new = Heater kW rated x (unit power distribution voltage/rated heater voltage)
As an example: For a 16 kW heater rated at 240 v with a power distribution voltage of 215 v kW new = 16 kW (215/240) kW new = 12.8 kW (rating at 215 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 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 is unavailable.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage
imbalance. % Voltage Imbalance
= 100 x

(AC) 457 – 455 = 2 v Maximum deviation is 7 v. Determine percent of voltage imbalance. % Voltage Imbalance = 100 x
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.

N/A — Not available 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. Deter-
mine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 548F060 unit with MCA = 35.6 and MOCP = 40, with CRPWREXH030A01 power exhaust. MCA New = 35.6 amps + 1.6 amps = 37.2 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 40 amps and the MCA New is below 40; therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. In all cases, the MOCP for the power exhaust should be 15 amps per NEC.

N/A — Not available 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. Deter-
mine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 548F060 unit with MCA = 35.6 and MOCP = 40, with CRPWREXH030A01 power exhaust. MCA New = 35.6 amps + 1.6 amps = 37.2 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 40 amps and the MCA New is below 40; therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. In all cases, the MOCP for the power exhaust should be 15 amps per NEC.

MOCP. Check MCA and MOCP when power exhaust is powered through the u nit. Determine the new MCA including the power exhaust using th e following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 548F060 unit with MCA = 35.6 and MOCP = 40, with CRPWREXH030A01 power exhaust. MCA New = 35.6 amps + 1.6 amps = 37.2 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 40 amps and the MCA New is below 40; therefore the MOCP is acceptable. If “MCA New” is lar ger tha n the pu blis hed MO CP, raise the MOCP to the next larger size. In all cases, the MOCP for the power exhaust should be 15 amps per NEC.

SELECTION PROCEDURE (WITH 549B048 EXAMPLE)
549B, 549C
I DETERMINE COOLING AND HEATING REQUIRE-
MENTS 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 46,300 Btuh and a sensible heat capacity of 35,600 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 22,400 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, 12,600 Btuh (35,000 – 22,400) additional electric heat is required.
Determine additional electric heat capacity in kW.
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 42,810 Btuh (22,400 +
20,410).
IV DETERMINE FAN SPEED AND POWER REQUIRE-
MENTS 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 EconoMi$erIV .07 in. wg Electric heat .09 in. wg
Total static pressure .61 in. wg
Enter the Fan Performance table for 549B048 vertical dis­charge at 1600 cfm and .61 in. wg static pressure. The bhp is 0.79 and the watts are 781. The rpm is 997. The standard motor 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
= 46,300 Btuh – (781 Watts x 3.413
Btuh/Watts) = 46,300 Btuh – 2665 Btuh = 43,635
Net sensible capacity = 35,600 Btuh – 2665 Btuh
= 32,935 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 42,810 Btuh, the total heating capacity determined in Step III.
12,600 Btuh
3413 Btuh/kW
= 3.7 kW of heat required.
