SINGLE AND THREE PHASE

2--5 NOMINAL TONS (SIZES 024--060)

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. 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.

Efficient operation High--efficiency design offers SEER (Seasonal Energy Efficiency Ratios) of up to 13.5 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.

PY3G have 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 where a Low NOx rule exists. Low NOx option is available on single phase models only.

Durable, dependable components Compressors 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.

Direct--drive high efficiency brushless DC multi--speed blower motor is standard on all PY3G models.

Direct-- drive PSC condenser-- fan motors are designed to help

reduce energy consumption and provide for cooing operation downto40_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. 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 ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 75dBA.

Easy to service cabinets provide easy single--panel accessibility to serviceable components during maintenance and installation. The basepan with integrated drain pan provides easy ground level installation 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. (19.05 mm) 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 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 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 62.2.) The sloped drain pan minimizes standing water in the drain. An external drain is provided.

Enter Net Cooling Capacities table at condenser entering temperature of 95°F(35°C). Unit 036 at 1200 cfm and 67°F (19°C) ewb (entering wet bulb) will provide a total capacity of 34,400 Btuh and a SHC of 25,900 Btuh. Calculate SHC correction,

PY3G

if required, using Note 4 under Cooling Capacities tables.

3. Select heating capacity of unit to provide design condition requirement.

In the Heating Capacities and Efficiencies table, note that the unit 036090 will provide 72,000 Btuh with an input of 90,000 Btuh.

4. Determine fan speed and power requirements at design conditions.

Before entering the air delivery tables, calculate the total static pressure required. From the given example, the Wet Coil Pressure Drop T able, and the Filter Pressure Drop Table:

External Static Pressure 0.300 IN. W.C.

Filter 0.130 IN. W.C. Wet Coil Pressure Drop 0.100 IN. W

Total Static Pressure 0.530 IN. W.C Enter the table for Dry Coil Air Delivery—Horizontal and

Downflow Discharge. At .530 IN. W.C. ESP, the closest speed to 1200 CFM is Med--High (orange wire), which delivers 1316 CFM at .6 in ESP.

5. Select unit that corresponds to power source available.

The Electrical Data Table shows that the unit is designed to operate at 230--1--60.

LEGEND BF— Bypass Factor edb— Entering Dry--- Bulb Ewb— Entering Wet---Bulb kW — Total Unit Power Input SHC— Sensible Heat Capacity (1000 Btuh) TC — Total Capacity (1000 Btuh) (n et) rh—Relative Hu midity

COOLING NOTES:

1. Ratings are net; they account for the effects of the evaporator--- fan motor power and heat.

2. Direct interpolation is permissible. Do not extrapolate.

3. The following formulas may be used:

ldb =tedb

Wet---bulb temperature corresponding to enthalpy

lwb =

air leaving evaporator coil (

lwb =he w b ---

ewb = Enthalpy of air entering evaporator coil

Where:

4. The SHC is based on 80_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.

APPLICATION DATA

Condensate trap — A 2--in. (51 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(--18_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.

CONTROLS

Operating sequence

Heating -- 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 burner 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 “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

PY3G

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 “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 compressor has started and then stopped, it cannot be restarted again until 5 minutes have elapsed.
