Outdoor Heat Pump

13 SEER High Efficiency Split System

These units have been designed and tested for capacity and efficiency in accordance with A.R.I.

Standards. Split System Heat Pump units are designed for use with a wide variety of fossil fuel

furnaces, electric furnaces, air handlers, and evaporator coil combinations.

These instructions are primarily intended to assist qualified individuals experienced in the proper

installation of heating and/or air conditioning appliances. Some local codes require licensed

installation/service personnel for this type of equipment. Read all instructions carefully before

starting the installation.

USER'S INFORMATION

Read this owner information to become familiar with the capabilities and use of your appliance.

Keep this with literature on other appliances where you have easy access to it in the future. If a

problem occurs, check the instructions and follow recommendations given. If these suggestions

don't eliminate your problem, call your servicing contractor.

Heat Pump Principle of Operation

WINTER HEATING

1. Outdoor air enters heat pump.

2. Cold, heat-transfer section (outdoor coil)

extracts heat from outdoor air as refrigerant

evaporates from a liquid to a gas.

3. Refrigerant, compressed to a hot gas by

heat pump, carries the heat to the hot heat-

transfer section (indoor coil).

4. Hot, heat-transfer section (indoor coil)

releases the heat to indoor air as refrigerant

condenses from a gas to a liquid.

5. Air handler circulates the heat throughout

the home.

6. Refrigerant returns to outdoor coil and

evaporates once again to absorb more

heat.

SUMMER COOLING

1. Indoor air enters the air handler section.

2. Cold, heat-transfer section (indoor coil)

extracts heat from indoor air as refrigerant

evaporates from a liquid to a cold gas.

3. Refrigerant, drawn to heat pump and

compressed to a hot gas by heat pump,

carries the heat outdoors.

4. Hot, heat-transfer section (outdoor coil)

releases the heat as refrigerant condenses

from a gas to a liquid.

5. Heat pump (outdoor fan) discharges the

heat to outside air.

6. Refrigerant returns to indoor coil and

evaporates once again to absorb more

heat.

OPERATING iNSTRUCTiONS . TO OPERATE YOUR HEAT PUMP FOR COOLING 1. Set the thermostat system switch to COOL and the thermostat fan switch to AUTO. (See Figure 1) . Set the thermostat temperatu re to the desired temperature level using the temperature selector. Please refer to the separate detailed thermostat user's manual for complete instructions regarding thermostat programming.

ReadYour Warranty Please read the separate warranty document completely. It contains valuable information about your system. GENERAL INFORMATION Read the following instructionscompletely before performing the installation. Outdoor Unit Section -- Each outdoor unit is shipped with a refrigerant charge adequate to operate the outdoor section with an indoor matching coil or air handler. Units with braze connections include the proper amount of refrigerant for an additional 15 ft.
PAGE 5
iNSTALLiNG THE OUTDOOR Slab Mount--The UNiT site selected for a slab mount installation requires a stable foundation and one not subject to erosion. The slab should be level and anchored (if necessary) prior to placing the equipment on the slab. Cantilever Mount --The cantilever mount should be designed with adequate safety factor to support the weight of the equipment, and for loads subjected to the mount during operation.
PAGE 6
Control Circuit Wiring --The outdoor unit is designed to operate from a 24VAC Class II control circuit. Control circuit wiring must comply with the current provisions of the "National Electrical Code" (ANSI/N FPA 70) and with applicable focal codes having jurisdiction. Thermostat connections should be made in accordance with the instructions supplied with the thermostat, and with the instructions supplied with the indoor equipment.

Functional Checkout: CAUTION: if equipped with a compressor crankcase heater, wait 24 hours prior to performing a function checkout to allow for heating of the compressor crankcase. Failure to comply may result in damage and could cause premature failure of the system. Indoor Blower -- Set the thermostat function switch to COOLING and the fan switch to ON. Verify that the indoor blower is operating and that airflow is not restricted. Set the fan switch back to AUTO.
