FEATURES/BENEFITSOne--piece heating and cooling units with low sound levels, easyinstallation, low maintenance, and dependable performance.

Puron Environmentally Sound Refrigerant is Bryant’s uniquerefrigerant designed to help protect the environment. Puron is anHFC refrigerant which does not contain chlorine that can harm theozone layer. The most important advantage of Puron refrigerant isthat it has not been banned in future air conditioning systems as thetraditional refrigerant R--22 has been. Puron refrigerant is in servicein millions of systems proving highly reliable, environmentallysound performance.

Easy InstallationFactory--assembled package is a compact, fully self--contained,combination gas heating/electric cooling unit that is prewired,pre--piped, and pre--charged for minimum installation expense.These units are available in a variety of standard and optionalheating/ cooling size combinations with voltage options to meetresidential and light commercial requirements. Units arelightweight and install easily on a rooftop or at ground level. Thehigh tech composite base eliminates rust problems associated withground level applications.

Innovative Unit Base DesignOn the inside a high--tech composite material will not rust andincorporates a sloped drain pan which improves drainage and helpsinhibit mold, algae and bacterial growth. On the outside metal baserails provide added stability as well as easier handling and rigging.

Convertible duct configurationUnit is designed for use in either downflow or horizontalapplications. Each unit can be converted from horizontal todownflow and includes two horizontal duct covers. Downflowoperation is provided in the field to allow vertical ductworkconnections. The basepan seals on the bottom openings to ensure apositive seal in the vertical airflow mode.

Efficient operation High--efficiency design offers SEER(Seasonal Energy Efficiency Ratios) of 14.2 to 14.5, 12.0 EER,and AFUE (Annual Fuel Utilization Efficiency) ratings as high as80.4%.

Energy--saving, direct spark ignition saves gas by operating onlywhen the room thermostat calls for heating. Standard units arefurnished with natural gas controls. A low--cost field installed kitfor propane conversion is available for all units.

Low NOx units are designed for California installations. Thesemodels meet the California maximum oxides of nitrogen (NOx)emissions requirement of 40 nanograms/joule or less as shippedfrom the factory and MUST be installed in California Air QualityManagement Districts and wherever a Low NOx rule exists.

Durable, dependable components Compressors are designedfor high efficiency. Each compressor is hermetically sealed againstcontamination to help promote longer life and dependableoperation. Each compressor also has vibration isolation to providequieter operation. All compressors have internal high pressure andovercurrent protection.

Monoport inshot burners produce precise air--to--gas mixture,which provides for clean and efficient combustion. The largemonoport on the inshot (or injection type) burners seldom, if ever,requires cleaning. All gas furnace components are accessible in onecompartment.

Turbo--tubulart heat exchangers are constructed of aluminizedsteel for corrosion resistance and optimum heat transfer forimproved efficiency. The tubular design permits hot gases to makemultiple passes across the path of the supply air.

In addition, dimples located on the heat exchanger walls force thehot gases to stay in close contact with the walls, improving heattransfer.

ECM Motor is standard on all 577C----A models.

Direct--drive PSC (Permanent Split Capacitor) condenser--fanmotors are designed to help reduce energy consumption andprovide for cooing operation down to 40_F (4.4_C) outdoortemperature. Motormasterr II low ambient kit is available as afield--installed accessory.

Thermostat controlsTime Guardr II anti--short cycle protection circuitry. If anon--corporate thermostat without anti--short cycle protection isused the Time Guard II field--installed anti--short cycle kit isrecommended.

Thermostatic Expansion Valve -- A hard shutoff, balance portTXV maintains a constant superheat at the evaporator exit (coolingcycle) resulting in higher overall system efficiency.

Refrigerant system is designed to provide dependability. Liquidfilter driers are used to promote clean, unrestricted operation. Eachunit leaves the factory with a full refrigerant charge. Refrigerantservice connections make checking operating pressures easier.

High and Low Pressure Switches provide added reliability for thecompressor.

Indoor and Outdoor coils are computer--designed for optimumheat transfer and efficiency. The indoor coil is fabricated fromcopper tube and aluminum fins and is located inside the unit forprotection against damage. The outdoor coil is internally mountedon the top tier of the unit.

Low sound ratings ensure a quiet indoor and outdoorenvironment with sound ratings as low as 73dBA.

Easy to service cabinets provide easy 3--panel accessibility toserviceable components during maintenance and installation. Thebasepan with integrated drain pan provides easy ground levelinstallation with mounting pad. A nesting feature ensures a positivebasepan to roof curb seal when the unit is roof mounted. Aconvenient 3/4--in. (19.05 mm) wide perimeter flange makes framemounting on a rooftop easy.

Standard horizontal metal duct covers with insulation comewith the unit and cover the horizontal duct openings. These can beleft in place if the units are converted to downflow.

Integrated Gas Control (IGC) board provides safe and efficientcontrol of heating and simplifies trouble--shooting through itsbuilt--in diagnostic function.

Cabinets are constructed of heavyduty, phosphated, zinc--coatedprepainted steel capable of withstanding 500 hours in salt spray.Interior surfaces of the evaporator/heat exchanger compartment areinsulated with cleanable semi--rigid insulation board, which keepsthe conditioned air from being affected by the outdoor ambienttemperature and provides improved indoor air quality. (Conformsto American Society of Heating, Refrigeration and AirConditioning Engineers 62.2.) The sloped drain pan minimizesstanding water in the drain. An external drain is provided.

Unit 036 at 1200 cfm and 67°F(19°C) ewb (entering wet bulb) will provide a total capacity of34,200 Btuh and a SHC of 27,400 Btuh. Calculate SHC correction,if required, using Note 4 under Cooling Capacities tables.

3. Select heating capacity of unit to provide designcondition requirement.In the Heating Capacities and Efficiencies table, note that the unit036090 will provide 72,000 Btuh with an input of 90,000 Btuh.

4. Determine fan speed and power requirements atdesign conditions.Before entering the air delivery tables, calculate the total staticpressure required. From the given example, the Wet Coil PressureDrop Table, and the Filter Pressure Drop Table:

External Static Pressure 0.10 IN. W.C.

Filter 0.07 IN. W.C.

Wet Coil Pressure Drop 0.18 IN. W.C.

Total Static Pressure 0.28 IN. W.C.

Enter the table for Dry Coil Air Delivery—Horizontal andDownflow Discharge. At .287 in. wc ESP, the closest speed to1200 CFM is Med--Low (pink wire), which delivers 1262 CFM at.3 in ESP.

5. Select unit that corresponds to power sourceavailable.The Electrical Data Table shows that the unit is designed to operateat 208--1--60.

APPLICATION DATACondensate trap — A 2--in. (50.8 mm) condensate trap must befield supplied.

Ductwork — Secure downflow discharge ductwork to roof curb.For horizontal discharge applications, attach ductwork to unit withflanges.

To convert a unit to downflow discharge — Units are equippedwith factory--installed inserts in the down--flow openings. Use theduct cover to seal the horizontal discharge openings in the unit.Units installed in horizontal discharge orientation do not requireduct covers.

Airflow — Units are draw--thru in the cooling mode andblow--thru in the heating mode.

Maximum cooling airflow — To minimize the possibility ofcondensate blow--off from the evaporator, airflow through the unitsshould not exceed 450 cfm per ton.

Minimum cooling airflow — Minimum cooling airflow is 350cfm per ton.

Minimum ambient cooling operation temperature — Allstandard units have a minimum ambient operating temperature of40_F (4_C). With accessory low ambient temperature kit, units canoperate at temperatures down to 0_F (--17_C).

CONTROLSOperating sequenceHeating -- On a call for heating, terminal “W” of the thermostat isenergized, starting the induced--draft motor. When the pressureswitch senses that the induced--draft motor is moving sufficientcombustion air, the burner sequence begins. This function isperformed by the integrated gas unit controller (IGC). The indoor(evaporator)--fan motor is energized 45 sec after flame isestablished. When the thermostat is satisfied and “W” isde--energized, the burners stop firing and the indoor (evaporator)fan motor shuts off after a 45--sec time--off delay. Please note thatthe IGC has the capability to automatically reduce the indoor fanmotor on delay and increase the indoor fan motor off delay in theevent of high duct static and/or partially--clogged filter.

Cooling — When the system thermostat calls for cooling, 24 V issupplied to the “Y1/Y” and “G” terminals of the thermostat. Thiscompletes the circuit to the contactor coil (C) and indoor(evaporator) fan relay (IFR). The normally open contacts ofenergized C close and complete the circuit through compressormotor (COMP) to outdoor (condenser) fan motor (OFM). Bothmotors start instantly. The set of normally open contacts ofenergized IFR close and complete the circuit through IFM. TheIFM starts instantly.

On the loss of the thermostat call for cooling, 24 V is removedfrom both the “Y1/Y” and “G” terminals (provided the fan switchis in the “AUTO” position) de--energizing the compressorcontactor and opening the contacts supplying power tocompressor/OFM. After a 90--second delay, the IFM shuts off. Ifthe thermostat fan selector switch is in the “ON” position, the IFMwill run continuously.

NOTE: On units with a Time Guard® II device: Once thecompressor has started and then stopped, it cannot be restartedagain until 5 minutes have elapsed.
