FEATURES/BENEFITS One--piece heating and cooling units with low sound levels, easy installation, low maintenance, and dependable performance. Puron Environmentally Sound Refrigerant is Carrier’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. Puron refrigerant is in service in millions of 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, pre--piped, and pre--charged for minimum installation expense. These units are available in a variety of standard and optional
High--efficiency design offers SEER (Seasonal Energy Efficiency Ratios) of 15.0 to 16.0, 12.0 to 12.5 EER, and AFUE (Annual Fuel Utilization Efficiency) ratings as high as 80.4%. 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. 48VGN--A units are dedicated Low NOx units designed for California installations. These models 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 and wherever a Low NOx rule exists.
Durable, dependable components Compressors have two stages of cooling and 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 large monoport 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. Stainless steel heat exchanger available as factory installed option. 1
48VG -- A
Multi--speed ECM Blower Motor is standard on all 48VG--A models. Direct--drive PSC (Permanent Split Capacitor) 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. 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. High 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. Low sound ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 72dBA. Dehumidification Feature This unit has independent fan speeds for low stage cooling and high stage cooling. In addition, 208/230 VAC models have the field--selectable capability to run an enhanced dehumidification (’DHUM’) speed on high stage cooling (as low as 320CFM per ton). Coupled with the improved dehumidification associated with low stage cooling, the DHUM speed allows for a complete dehumidification solution independent of cooling stage. 208/230 VAC models also have independent fan speeds for low stage gas heating and high stage gas heating. The dehumidification control must open the control circuit on humidity rise above the dehumidification set point. NOTE: The enhanced dehumidification feature on high stage cooling does not support use of an economizer. Heating S Reliable direct spark ignition system S Two--speed PSC inducer motor with ball bearings (208/230 VAC models) S Low stage heating delivers 65% of high--stage capacity (208/230 VAC models) Easy to service cabinets provide easy 3--panel accessibility to serviceable components during maintenance and installation. The basepan with integrated drain pan provides easy ground level installation with mounting pad. A nesting feature ensures a positive basepan to roof curb seal when the unit is roof mounted. A convenient 3/4--in. (19.05 mm) wide perimeter flange makes frame mounting on a rooftop easy. Standard horizontal 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 control of heating and simplifies trouble--shooting through its built--in 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 foil--faced insulation, 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 62.2.) The sloped drain pan minimizes standing water in the drain. An external drain is provided. Louvered grille provides hail and vandalism protection for the coil.

Given: Required Cooling Capacity (TC) . . . . . . . . . . 34,000 Btuh Sensible Heat Capacity (SHC) . . . . . . . . . . . . 25,000 Btuh Required Heating Capacity . . . . . . . . . . . . . . . 60,000 Btuh Condenser Entering Air Temperature . . . . . . . 95F (35C) Indoor--Air Temperature . 80F (26C)edb 67F (19C)ewb Evaporator Air Quantity . . . . . . . . . . . . . . . . . . 1200 CFM External Static Pressure . . . . . . . . . . . . . . . . 0.100 IN. W.C. Electrical Characteristics . . . . . . . . . . . . . . . . . . . 208--1--60
Before entering the air delivery tables, calculate the total static pressure required. From the given example, the Wet Coil Pressure Drop Table, and the Filter Pressure Drop Table: External Static Pressure 0.100 IN. W.C Filter 0.07 IN. W.C Wet Coil Pressure Drop 0.180 IN. W.C Total Static Pressure 0.287 IN. W.C Enter the table for Dry Coil Air Delivery—Horizontal and Downflow Discharge. At .287 IN. W.C. ESP, the closest speed to 1200 CFM is Med--Low (pink wire), which delivers 1262 CFM at .3 in ESP.
2. Select unit based on required cooling capacity. Enter Net Cooling Capacities table at condenser entering temperature of 95F (35C). Unit 036 at 1200 cfm and 67F (19C) ewb (entering wet bulb) will provide a total capacity of 34,200 Btuh and a SHC of 27,400 Btuh. Calculate SHC correction, if required, using Note 4 under Cooling Capacities tables.
5. Select unit that corresponds to power source available. The Electrical Data Table shows that the unit is designed to operate at 208--1--60.
3. Select heating capacity of unit to provide design condition requirement. In the Heating Capacities and Efficiencies table, note that the unit 036090 (208/230 VAC) will provide 74,000 Btuh with an input of 90,000 Btuh in high stage and will provide 47,000 Btuh of heating in low stage.

Where: hewb = Enthalpy of air entering evaporator coil 4. The SHC is based on 805 F (26.6_C) edb temperature of air entering evaporator coil. Below 80_F (26.6_C) edb, subtract (corr factor x cfm) from SHC. Above 80_ F (26.6_C) edb, add (corr factor x cfm) to SHC. Correction Factor = 1.10 x (1 + BF) x (edb --- 80). 5. Integrated capacity is maximum (instantaneous) capacity less the effect of frost on the outdoor coil and the heat required to defrost it.

Condensate trap — A 2--in. (50.8 mm) condensate trap must be 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 — All standard 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 55_F (13_C) continuous and a maximum of 80_F (27_C) continuous.

Operating sequence 208/230 VAC Models: On a call for low stage heating, terminal W1 on the thermostat is energized. On a call for high stage heating both terminals W1 and W2 are energized. Regardless of the stage of the heating call, the induced--draft motor is turned on to high speed for a 15 sec pre--purge time. After the pre--purge, when the pressure switch senses that sufficient combustion air is being moved by the induced--draft motor, the ignition sequence begins. The IGC will energize the sparker and the low stage gas valve solenoid. Upon sensing flame, the IGC will check the heating call. If W2 is not energized, the IGC will drop the induced--draft motor to low speed and maintain the gas valve on low stage. If W2 is energized, the IGC will maintain the induced--draft motor on high speed and energize the high stage gas valve solenoid. Thirty sec after flame is sensed the IGC will turn on the evaporator fan motor. If W2 is not energized, the evaporator fan motor will run on low heat speed. If W2 is energized, the evaporator fan motor will run on high heat speed. After the call for heat is satisfied, the IGC will run the evaporator fan motor an additional field--selectable time of 90, 120, 150, or 180 sec before shutting the evaporator fan motor off. 460 VAC Models: On a call for heating, terminal W of the thermostat is energized, starting the induced--draft motor. When the pressure switch senses that the induced--draft motor is moving sufficient combustion air, the ignition sequence begins. This function is performed by the integrated gas unit controller (IGC). The indoor (evaporator)--fan motor is energized 45 sec after flame is established. When the thermostat is satisfied and W is de--energized, the burners stop firing and the indoor (evaporator) fan motor shuts off after a 45--sec time--off delay. Please note that the IGC has the capability to automatically reduce the indoor fan motor on delay and increase the indoor fan motor off delay in the event of high duct static and/or partially--clogged filter. Cooling — When the system thermostat calls for cooling, 24 V is supplied to the “Y1/Y” and “G” terminals of the thermostat. This completes the circuit to the contactor coil (C) and indoor (evaporator) fan relay (IFR). The normally open contacts of energized C close and complete the circuit through compressor motor (COMP) to outdoor (condenser) fan motor (OFM). Both motors start instantly. The set of normally open contacts of energized IFR close and complete the circuit through IFM. The IFM starts instantly.
On the loss of the thermostat call for cooling, 24 V is removed from both the “Y1/Y” and “G” terminals (provided the fan switch is in the “AUTO” position) de--energizing the compressor contactor and opening the contacts supplying power to compressor/OFM. After a 60--second delay, the IFM shuts off. If the thermostat fan selector switch is in the “ON” position, the IFM will run continuously. NOTE: On units with a Time Guard II device: Once the compressor has started and then stopped, it cannot be restarted again until 5 minutes have elapsed.
