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.

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. 2 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. 3 OPTIONS AND ACCESSORIES ITEM 100% Open Two-Position Damper (036-120) 25% Open Two-Position Damper Alternate Motors and Drives (548F036-120) Barometric Relief Damper (150 and 180 only, not for use with horizontal roof curb) Convenience Outlet 115V Copper fins indoor and outdoor coil Copper fins outdoor coil Double Wall in unit airstream (150,180) E-Coat outdoor coil (Aluminum Fin) E-Coat outdoor coil (Copper Fin) EconoMi$er EconoMi$er with Power Exhaust Electric Heat Electronic Programmable Thermostat Emergency Heat Package Enthalpy or differential enthalpy sensor Fan/Filter Status High-Static Motor and Drive (548F036-120) Hinged Access Panels (549B036-120 and 542J150,180) Horizontal Adapter Curb (150,180) Hot Gas Bypass (150,180) Hydronic Glycol Coil (150,180) Johnson METASYS Control Manual Outdoor-Air Damper (25% Open) (036-120) Manual Outdoor-Air Damper (50% Open) (036-120) Motormaster® Head Pressure Control (Cycle Control or Fan Speed Modulation) Novar Control Outdoor Air Enthalpy Sensor (EconoMi$er Only) Outdoor Coil Grille (036-120) Outdoor Coil Hail Guard Assembly Power Exhaust (no barometric relief on sizes 150,180) Power Exhaust Transformer for 460 or 575 v (036-120) Power Exhaust with Barometric Relief (036-120) Precoat Al.

It permits tool-less filter access. 9 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$er — Upon a call for cooling, when outdoor ambient temperature is above the temperature control setting, the indoor and outdoor fans and compressor(s) energize. The economizer damper moves to vent position. Upon a first-stage call for cooling, when outdoor ambient temperature is below the temperature control setting, the indoor fan starts and economizer damper modulates to maintain mixed-air temperature. The compressor(s) remains off. Upon a second-stage call for cooling, compressor no. 1 (542J180) or loaded compressor (542J150) is energized and mechanical cooling is integrated with economizer cooling. Compressor no. 2 (542J180) is locked out. If the air temperature is below 50 F, a cooling lockout switch prevents the compressor(s) from running. When supply-air temperature drops below a fixed set point, the economizer damper modulates to maintain the temperature at the fixed set point. A freeze protection thermostat (FPT) is located on the indoor coil. It detects frost build-up and turns off the compressor(s), allowing the coil to clear. Once frost has melted, the compressor can be reenergized. 11 CONTROLS (cont) Heating, Units Without Economizer — With unit main power on, set thermostat at HEAT position and desired room temperature. Set fan switch at AUTO. (on demand) or ON (continuous) position. On a drop in room temperature, heating contactor no. 1 in the thermostat closes, energizing heat relay (HR), reversing valve relay (RVR), reversing valve solenoids (RVS1 and RVS2) and compressor no. 2 contactor. Compressor (542J150) or compressor no. 2 (542J180) and indoor and outdoor fan motors start. If the 5-minute CTD on the DB is satisfied, then compressor no. 1 contactor is energized and compressor no. 1 will start. On units equipped with electric heat, when additional heat is needed, heating contactor no. 2 in the thermostat closes, energizing W2. Heating, Units With EconoMi$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. 12 CONTROLS (cont) LEGEND Field Wiring Field-Supplied Switch See Legend on page 14. *Included in power exhaust accessory.

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.

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. 50TFQ004-012 548F036-120 PERFORMANCE DATA COOLING CAPACITIES 548F036 (3 TONS) Temp (F) Outdoor Entering Air (Edb) 75 85 95 105 115 125 TC SHC kW TC SHC kW TC SHC kW TC SHC kW TC SHC kW TC SHC kW 900/0.10 72 42.4 16.7 2.77 41.5 16.6 3.01 40.0 16.2 3.24 38.4 15.7 3.47 36.1 15.1 3.66 34.2 14.6 3.88 67 39.9 22.0 2.71 38.4 21.6 2.92 36.3 20.9 3.10 34.7 20.5 3.32 32.5 19.8 3.50 30.5 19.2 3.68 Indoor Entering Air — Cfm/BF 1200/0.15 1500/0.21 Indoor Entering Air — Ewb (F) 62 72 67 62 72 67 62 36.5 43.0 41.2 38.7 45.1 42.8 40.3 26.8 17.5 24.2 30.9 19.3 26.9 34.1 2.62 2.78 2.74 2.68 2.85 2.79 2.73 34.8 43.3 40.4 37.0 44.0 41.7 38.7 26.2 18.2 24.6 30.3 19.3 27.2 33.7 2.80 3.07 2.98 2.88 3.09 3.03 2.94 33.0 42.3 38.5 35.2 43.4 40.0 36.7 25.7 18.2 24.2 29.8 19.7 27.2 32.7 2.99 3.32 3.19 3.07 3.36 3.24 3.13 31.0 40.0 36.7 33.1 41.2 37.7 35.2 24.8 17.5 23.9 28.8 19.3 26.6 31.7 3.16 3.53 3.41 3.26 3.58 3.44 3.35 28.9 38.1 34.3 31.1 39.3 35.5 33.2 23.9 17.2 23.2 27.8 19.1 26.2 30.2 3.32 3.76 3.59 3.44 3.81 3.65 3.54 26.8 35.9 32.0 29.3 36.8 33.0 31.3 22.9 16.7 22.6 26.3 18.5 25.5 28.4 3.49 3.97 3.77 3.62 4.02 3.83 3.74 548F048 (4 TONS) Temp (F) Outdoor Entering Air (Edb) 75 85 95 105 115 125 TC SHC kW TC SHC kW TC SHC kW TC SHC kW TC SHC kW TC SHC kW 1200/0.11 72 55.5 24.5 3.80 53.4 23.8 4.10 52.0 23.4 4.47 49.3 22.5 4.77 46.6 21.7 5.08 44.0 20.9 5.45 67 51.9 31.2 3.70 49.7 30.4 3.99 47.4 29.6 4.28 45.0 28.8 4.59 42.4 27.9 4.90 39.6 26.9 5.21 Indoor Entering Air — Cfm/BF 1600/0.15 2000/0.22 Indoor Entering Air — Ewb (F) 62 72 67 62 72 67 62 47.4 56.9 54.6 50.3 59.3 56.5 52.1 37.4 26.0 35.2 43.4 28.4 39.0 47.6 3.55 3.84 3.79 3.66 3.93 3.86 3.71 45.3 56.3 52.6 47.8 57.5 54.1 49.8 36.7 26.3 34.9 42.6 28.3 38.6 46.9 3.84 4.23 4.11 3.94 4.27 4.16 4.01 43.0 53.7 49.9 45.5 54.5 51.6 47.4 35.8 25.5 33.9 41.6 27.3 38.2 45.2 4.11 4.53 4.39 4.23 4.56 4.48 4.29 40.6 51.8 47.2 43.0 52.6 48.7 45.4 34.7 25.3 33.0 40.3 27.1 37.1 43.3 4.39 4.90 4.68 4.52 4.92 4.76 4.63 38.0 48.8 44.6 40.6 50.2 45.8 43.2 33.6 24.3 32.4 38.7 26.8 36.1 41.2 4.66 5.21 5.01 4.81 5.29 5.06 4.96 35.4 45.6 41.6 38.3 47.0 42.9 40.9 32.4 23.3 31.6 36.5 25.9 35.6 39.0 4.96 5.51 5.34 5.14 5.60 5.41 5.30 548F060 (5 TONS) Temp (F) Outdoor Entering Air (Edb) 75 85 95 105 115 125 TC SHC kW TC SHC kW TC SHC kW TC SHC kW TC SHC kW TC SHC kW 1500/0.05 72 69.3 30.9 4.28 67.7 30.4 4.76 65.2 29.6 5.27 62.3 28.6 5.79 59.7 27.6 6.37 56.5 26.8 7.03 67 64.5 39.2 4.15 62.4 38.6 4.61 59.8 37.6 5.10 57.2 33.8 5.66 54.2 35.8 6.24 51.0 34.7 6.87 Indoor Entering Air — Cfm/BF 2000/0.08 2500/0.14 Indoor Entering Air — Ewb (F) 62 72 67 62 72 67 62 59.3 70.8 67.9 62.8 72.9 69.3 65.4 47.4 33.1 44.9 55.4 35.8 49.4 61.4 4.03 4.32 4.25 4.12 4.38 4.29 4.19 56.8 69.1 65.7 60.2 71.1 67.7 63.2 46.5 32.8 44.6 54.4 35.8 50.0 59.8 4.49 4.79 4.72 4.56 4.86 4.78 4.65 54.4 67.7 62.9 57.6 69.1 64.8 60.7 45.5 32.8 43.6 53.2 35.6 49.3 57.7 4.97 5.35 5.20 5.07 5.39 5.27 5.14 51.8 65.1 59.6 54.9 66.8 61.7 58.3 44.4 32.1 42.6 51.6 35.4 48.2 55.5 5.50 5.90 5.73 5.61 5.97 5.79 5.68 49.0 61.7 57.0 52.5 63.2 58.4 55.8 43.2 31.1 41.9 49.6 34.3 47.0 53.2 6.06 6.47 6.34 6.20 6.53 6.36 6.31 46.0 58.2 53.5 49.8 59.4 55.1 53.0 41.9 30.0 40.8 47.3 33.0 46.5 50.5 6.65 7.07 6.96 6.82 7.13 7.03 6.96 26 BF Edb Ewb kW Ldb Lwb SHC TC LEGEND Bypass Factor Entering Dry-Bulb Entering Wet-Bulb Compressor Motor Power Input Leaving Dry-Bulb Leaving Wet-Bulb Sensible Heat Capacity (1000 Btuh) Gross — Total Capacity (1000 Btuh) Gross — — — — — — — NOTES: 1.

(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 of voltage imbalance. % Voltage Imbalance max voltage deviation from average voltage = 100 x average voltage 64 TYPICAL WIRING SCHEMATIC — — — — — — — — — — — — — — ER FSS FPT FU GND HC HPS HR IFC IFM LPS LSM MTR OAT OFM P PL QT R RAT RVS SAT — — — — — — — — — — — — — — — — — — — — — — ST SW1 SW2 SW3 — — — — SW4 — TB TC — — TH — TRAN — 50TFQ004-012 548F036-120 AHA AWG C CAP CB CC CH COMP D DB DFT EC ECON EPS LEGEND Adjustable Heat Anticipator American Wire Gage Contactor, Compressor Capacitor Circuit Breaker Cooling Capacitor Crankcase Heater Compressor Motor Diode Defrost Board Defrost Thermostat Enthalpy Control Economizer Emergency Power Supply (Nine-Volt Battery) Economizer Relay Filter Status Switch Freeze-Up Protection Thermostat Fuse Ground Heater Contactor (Strip Heat) High-Pressure Switch Heater Relay Indoor-Fan Contactor Indoor-Fan Motor Low-Pressure Switch Limit Switch (Manual Reset) Motor Outdoor-Air Thermostat Outdoor-Fan Motor Plug Plug Assembly Quadruple Terminal Relay Return-Air Thermostat Reversing Valve Solenoid Supply-Air Thermostat Start Thermistor Switch Fully Open Switch Fully Closed Switch Min.

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). 74 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.

(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. 92 ELECTRICAL DATA (cont) UNITS WITH ELECTRICAL CONVENIENCE OUTLET UNIT 549B 036 (3 Tons) NOMINAL VOLTAGE (V-Ph-Hz) RLA LRA FLA

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.

At 6000 cfm and 1.46 in. wg external static pressure, the fan 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 50TFQ004-012 542J150,180 111,500 Btuh = 32.6 kW 3412 Btuh/kW 108 PERFORMANCE DATA COOLING CAPACITIES 542J150 Temp (F) Air Ent Outdoor Coil TC SHC kW TC SHC kW TC SHC kW TC SHC kW TC SHC kW TC SHC kW 75 85 95 105 115 125 3750/0.04 72 167.0 79.6 10.00 160.0 77.6 11.10 155.0 76.1 12.20 147.0 73.6 13.20 140.0 71.4 14.20 131.0 68.1 15.20 67 154.0 100.0 9.77 148.0 98.9 10.80 141.0 96.3 11.80 133.0 93.3 12.70 126.0 90.3 13.70 118.0 87.6 14.70 4500/0.05 62 140.0 120.0 9.50 133.0 118.0 10.40 127.0 115.0 11.40 120.0 112.0 12.30 112.0 109.0 13.20 105.0 105.0 14.10 72 171.0 85.0 10.10 164.0 82.0 11.20 157.0 80.3 12.20 150.0 78.5 13.30 141.0 75.1 14.30 134.0 73.5 15.40 67 158.0 108.0 9.87 151.0 107.0 10.90 144.0 105.0 11.90 137.0 102.0 12.90 129.0 99.1 13.90 120.0 96.4 14.90 Air Entering Indoor Coil — Cfm/BF 5000/0.05 5625/0.06 Air Entering Indoor Coil — Ewb (F) 62 72 67 62 72 67 62 144.0 173.0 159.0 146.0 171.0 162.0 148.0 131.0 87.5 114.0 138.0 94.5 120.0 146.0 9.61 10.20 9.93 9.68 10.20 10.00 9.74 137.0 167.0 154.0 140.0 168.0 155.0 143.0 129.0 86.1 113.0 136.0 89.6 118.0 142.0 10.60 11.30 11.00 10.70 11.30 11.00 10.80 131.0 160.0 146.0 133.0 161.0 149.0 137.0 126.0 84.4 110.0 132.0 86.5 117.0 137.0 11.50 12.40 12.00 11.60 12.40 12.10 11.80 124.0 152.0 138.0 127.0 153.0 140.0 131.0 123.0 81.6 108.0 127.0 85.1 114.0 131.0 12.50 13.40 13.00 12.60 13.50 13.10 12.80 118.0 144.0 130.0 121.0 144.0 131.0 125.0 117.0 78.9 104.0 121.0 81.9 110.0 125.0 13.50 14.40 14.00 13.70 14.50 14.00 13.90 111.0 135.0 122.0 115.0 137.0 123.0 118.0 111.0 75.7 102.0 115.0 80.7 108.0 118.0 14.50 15.40 14.90 14.70 15.60 15.00 14.90 6250/0.07 72 173.0 97.7 10.20 166.0 95.3 11.30 163.0 91.7 12.50 154.0 88.6 13.50 146.0 87.0 14.60 136.0 83.4 15.60 67 161.0 127.0 10.00 157.0 125.0 11.10 149.0 121.0 12.10 141.0 120.0 13.10 133.0 117.0 14.10 124.0 113.0 15.10 62 151.0 150.0 9.80 146.0 146.0 10.80 140.0 140.0 11.90 134.0 134.0 12.90 128.0 128.0 14.00 121.0 121.0 15.00 542J180 Temp (F) Air Ent Outdoor Coil TC SHC kW TC SHC kW TC SHC kW TC SHC kW TC SHC kW TC SHC kW 75 85 95 105 115 125 BF Edb Ewb kW SHC TC — — — — — — 4500/0.06 72 210.0 100.6 13.58 202.0 98.0 14.86 192.4 94.8 16.16 182.0 91.0 17.36 171.2 87.4 18.54 159.4 83.6 19.64 67 192.0 125.2 13.12 183.0 121.8 14.32 173.2 118.0 15.52 163.0 114.2 16.64 152.4 110.2 17.72 141.2 105.8 18.74 5250/0.08 62 173.4 148.2 12.66 164.4 144.2 13.78 155.0 140.0 14.88 145.0 135.2 15.92 134.8 130.8 16.90 125.0 125.0 17.88 72 216.0 106.0 13.76 208.0 103.8 15.08 196.2 100.2 16.32 186.4 96.8 17.58 175.0 92.6 18.76 162.8 89.0 19.86 67 196.6 134.0 13.28 187.8 131.2 14.52 177.8 127.4 15.72 167.0 123.6 16.86 156.2 119.4 17.94 143.8 115.0 19.00 Air Entering Indoor Coil — Cfm/BF 6000/0.10 6750/0.10 Air Entering Indoor Coil — Ewb (F) 62 72 67 62 72 67 62 178.4 220.0 202.0 182.2 222.0 204.0 185.6 160.6 110.6 143.0 172.2 115.0 151.2 183.2 12.84 13.88 13.44 12.98 13.96 13.52 13.10 169.0 212.0 191.4 172.8 212.0 194.0 177.2 156.4 109.0 140.0 168.6 112.0 148.0 177.0 13.98 15.22 14.66 14.14 15.26 14.78 14.30 159.2 200.0 180.8 163.4 202.0 183.4 169.0 152.6 105.6 136.4 163.4 110.6 144.8 169.0 15.10 16.48 15.88 15.30 16.62 16.00 15.54 149.4 188.6 170.0 155.4 191.0 172.2 160.8 147.6 101.8 132.6 155.2 107.2 141.2 160.6 16.16 17.70 17.04 16.48 17.84 17.18 16.74 140.6 177.8 158.8 146.8 179.4 160.8 152.2 140.6 98.8 128.2 146.8 103.6 136.8 151.8 17.24 18.94 18.12 17.60 19.02 18.28 17.90 132.0 165.6 147.0 137.8 166.6 148.8 143.0 131.8 94.4 123.6 137.8 99.8 132.2 142.8 18.34 20.00 19.12 18.72 20.20 19.28 19.00 67 206.0 158.2 13.60 195.8 155.6 14.86 185.4 153.2 16.12 173.8 149.6 17.28 162.2 144.6 18.38 150.0 139.6 19.40 62 190.2 190.0 13.26 182.2 182.2 14.50 174.2 173.8 15.76 165.2 165.2 16.96 156.4 156.2 18.16 146.8 146.6 19.28 .05 .10 .20 .30 sensible capacity (Btuh) 1.10 x cfm tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving indoor coil (hlwb) ENTERING AIR DRY-BULB TEMP (F) 78 77 76 75 under 75 82 83 84 85 over 85 Correction Factor 1.04 2.07 3.11 4.14 5.18 .98 1.96 2.94 3.92 4.90 Use formula shown below. .87 1.74 2.62 3.49 4.36 .76 1.53 2.29 3.05 3.82 79 81 Interpolation is permissible.
