1 SINGLE -PACKAGED GAS HEATING/ELECTRIC COOLING UNITS WITH PURON (R -410A) REFRIGERANT SINGLE- AND 3 -PHASE UNITS 1-1/2 to 5 NOM TONS (SIZES ) Product Data Single-Packaged Products with Energy -Saving Features and PuronR refrigerant. S 13 SEER S Up to 81% AFUE S Factory -Installed TXV S Multi -Speed Blower -Standard S Direct Spark Ignition S Low Sound Levels Unit A99338 FEATURES/BENEFITS One-piece heating and cooling units with low sound levels, easy installation, low maintenance, and dependable performance. Puron Environmentally Sound Refrigerant is Bryant s unique refrigerant designed to help protect the environment. Puron is an HFC refrigerant which does not contain chlorine that can harm the ozone layer. The most important advantage of Puron refrigerant is that it has not been banned in future air conditioning systems as the traditional refrigerant R - has been. Puron refrigerant is in service in over 100,000 systems proving highly reliable, environmentally sound performance. Easy Installation Factory -assembled package is a compact, fully self -contained, combination gas heating/electric cooling unit that is prewired, prepiped, and pre-charged for minimum installation expense. These units are available in a variety of standard and optional heating/ cooling size combinations with voltage options to meet residential and lightcommercial requirements.units arelightweight and install easily on a rooftop or at ground level. The high tech composite base eliminates rust problems associated with ground level applications. Convertible duct configuration Unit is designed for easy use in either downflow or horizontal applications. Each unit is easily converted from horizontal to downflow with the two standard duct covers. Efficient operation -efficiency design offers SEER (Seasonal Energy Efficiency Ratios) of 13.0, and AFUE (Annual Fuel Utilization Efficiency) ratings as high as 81%. Energy -saving, direct spark ignition saves gas by operating only when the room thermostat calls for heating. Standard units are furnished with natural gas controls. A low -cost field installed kit for propane conversion is available for all units. Low NOx unitsdesigned forcaliforniainstallations. Thesemodels meet the California maximum oxides of nitrogen (NOx) emissions requirement of 40 nanograms/joule or less as shipped from the factory and MUST be installed in California Air Quality Management Districts where a Low NOx rule exists. Low NOx option is available on single phase models only. Durable, dependable componentscompressors are designed for high efficiency. Each compressor is hermetically sealed against contamination to help promote longer life and dependable operation. Each compressor also has vibration isolation to provide quieter operation. All compressors have internal high pressure and overcurrent 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 one compartment. Turbo -tubulart heat exchangers are constructed of aluminized steel for corrosion resistance and optimum heat transfer for improved efficiency. The tubular design permits hot gases to make multiple passes across the path of the supply air. In addition, dimples located on the heat exchanger walls force the hot gases to stay in close contact with the walls, improving heat transfer. Direct -drive multi -speed blower motor is standard on all models. 1

2 Direct-drive PSC condenser-fan motors are designed to help reduce energy consumption and provide for cooing operation down to 40_F(4.4_C) outdoor temperature. Motormasterr II low ambient kit is available as a field -installed accessory. Thermostat controls Time Guardr II anti -short cycle protection circuitry. If a non -corporate thermostat without anti-short cycle protection is used the Time Guard II field -installed anti-short cycle kit is recommended. Thermostatic Expansion Valve - A hard shutoff, balance port TXV maintains a constant superheat at the evaporator exit (cooling cycle) resulting in higher overall system efficiency. Refrigerant system is designed to provide dependability. Liquid filter driers are used to promote clean, unrestricted operation. Each unit leaves the factory with a full refrigerant charge. Refrigerant service connections make checking operating pressures easier. and Low Pressure Switches provide added reliability for the compressor. Indoor and Outdoor coils are computer-designed for optimum heat transfer and efficiency. The indoor coil is fabricated from copper tube and aluminum fins and is located inside the unit for protection against damage. The outdoor coil is internally mounted on the top tier of the unit. Copper fin coils and pre-coated fin coils are available from the factory by special order. These coils are recommended in applications where aluminum fins are likely to be damaged due to corrosion. They are ideal for seacoast applications. Low sound ratingsensure aquiet indoorand outdoorenvironment with sound ratings as low as 72dBA.

The basepan with integrated drain pan provides easy ground levelinstallation with or without a mounting pad. Convenient handholds are provided to manipulate the unit on the jobsite. A nesting feature ensures a positive basepan to roof curb seal when the unit is roof mounted. A convenient 3/4 -in. wide perimeter flange makes frame mounting on a rooftop easy. Standard metal duct covers with insulation come with the unit and cover the horizontal duct openings. These can be left in place if the units are converted to downflow. Integrated Gas Control (IGC) board provides safe and efficient controlofheating and simplifiestrouble-shooting through itsbuiltin diagnostic function. Cabinets are constructed of heavyduty, phosphated, zinc-coated prepainted steel capable of withstanding 500 hours in salt spray. Interior surfaces of the evaporator/heat exchanger compartment are insulated with cleanable semi -rigid insulation board, which keeps the conditioned air from being affected by the outdoor ambient temperature and provides improved indoor air quality. (Conforms to American Society of Heating, Refrigeration and Air Conditioning Engineers No. 62P.) The sloped drain pan minimizes standing water in the drain. An external drain is provided. Downflow operation is easily provided in the field to allow vertical ductwork connections. The basepan utilizes knockout style seals on the bottom openings to ensure a positive seal in the horizontal airflow mode. 2

20 APPLICATION DATA Condensatetrap A 2 -in.condensatetrap mustbe field supplied. Ductwork Secure downflow discharge ductwork to roof curb. For horizontal discharge applications, attach ductwork to unit with flanges. To convert a unit to downflow discharge Units are equipped with factory -installed inserts in the down -flow openings. Removal of the inserts is similar to removing an electrical knock -out. Use the duct cover to seal the horizontal discharge openings in the unit. Units installed in horizontal discharge orientation do not require duct covers. Airflow Units are draw -thru in the cooling mode and blow -thru in the heating mode. Maximum cooling airflow To minimize the possibility of condensate blow -off from the evaporator, airflow through the units should not exceed 450 cfm per ton. Minimum cooling airflow Minimum cooling airflow is 350 cfm per ton. Minimum ambient cooling operation temperature Allstandard units have a minimum ambient operating temperature of 40_F (4_C). With accessory low ambient temperature kit, units can operate at temperatures down to 0_F (-17_C). Minimum temperature Air entering the heat exchanger in heating mode must be a minimum of 50_F (10_C)continuous and/or 45_F (7_C) intermittent. 20

I f other than 60 C wire is used, or if length exceeds wire length in table, determine siz e from NEC.. 3. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percentage of voltage imbalance. % Voltage imbalance max voltage deviation from average voltage = 100 x average voltage (R) EXAMPLE: Supply voltage is AB = 8 v BC = 231 v AC = 7 v Average Voltage = = 3 = 9 Determine maximum deviation from average voltage. (AB) 9-8 =1v (BC) =2v (AC) 9-7 =2v Maximum deviation is 2 v. Determine percent of voltage imbalance. 2 % Voltage Imbalance = 100 x 9 = 0.8% 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. A
