Outdoor Heat Pump

14 SEER R-410A High Efﬁciency Split System

User’s Information/Installation Instructions

These units have been designed and tested for capacity and efﬁciency in accordance with AHRI

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 instal-

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

the installation.

IMPORTANT

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

USER’S INFORMATION

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.

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.

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) 2. Set the thermostat temperature 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. The outdoor unit and indoor blower will both cycle on and off to maintain the indoor temperature at the desired cooling level.

TO OPERATE YOUR HEAT PUMP FOR AUTOMATIC COOLING AND HEATING — 1. Set the thermostat system switch to AUTO and the thermostat fan switch to AUTO. (See Figure 1) Note: Thermostats will vary. Some models will not include the AUTO mode, and others will have the AUTO in place of the HEAT and COOL, and some will include all three. 2. Set the thermostat temperature to the desired heating and cooling temperature level(s).

refrigerant for an additional 15 ft. of refrigerant lines the same size as the valve fittings. NOTE: DO NOT USE ANY PORTION OF THE CHARGE FOR PURGING OR LEAK TESTING. Matching coils and air handlers may be shipped with a small holding charge to pressurize them to keep out contaminants. To release the pressure, read the indoor section installation instructions carefully. Liquid and Suction Lines — Fully annealed, refrigerant grade copper tubing should be used when installing the system.

nor transmit noise to the interior of the structure. Refrigerant and electrical line should be routed through suitably waterproofed openings to prevent water leaking into the structure. liquid line, the filter dryer must be replaced with the one supplied with the unit. The filter dryer must be installed in strict accordance with the manufacturer’s installation instructions. INSTALLING THE INDOOR UNIT Optional Equipment — Optional equipment (e.g.: liquid line solenoid valves, etc.

Minimum Circuit Ampacity — Electrical wiring to the equipment must be compatible and in compliance with the minimum circuit ampacity listed on the outdoor unit data label. Maximum Fuse/Circuit Breaker Size — Circuit protection for the outdoor unit must be compatible with the maximum fuse/circuit breaker size listed on the outdoor unit data label. Disconnect Switch — An electrically compatible disconnect switch must be within line of sight of the outdoor unit.

the thermostat inputs to the unit. Thus, when the switch opens and then closes, there will be a 5 minute short cycling delay before the outdoor unit will energize. High-Pressure Switch — A high-pressure switch is factory-installed and located in the compressor discharge line internal to the outdoor unit. The switch is designed to de-energize the system when very high pressures occur during abnormal conditions. Under normal conditions, the switch is closed.
PAGE 11
Heating — Lower the thermostat setpoint temperature to the lowest obtainable setting and set the thermostat function switch to HEATING. The indoor blower and outdoor unit should stop running. After a minimum of five minutes, increase the setpoint temperature of the thermostat to the maximum setting.Verify that the outdoor unit and indoor blower have energized. Feel the air being circulated by the indoor blower and verify that it is warmer than ambient temperature. Listen for any unusual noises.

Miswired Module Indication Recommended Troubleshooting Action Green LED is not on, module does not power up • Determine if both R & C module terminals are connected. • Verify voltage is present at module’s R & C terminals. Green LED intermittent, module powers up only when compressor runs • Determine if R & Y terminals are wired in reverse. • Verify modules R & C terminals have a constant source.

Defrost Test Procedure for 624656 Adjustment of Refrigerant Charge: 1. Jumper “T2” to “DFT” at the test terminals. 2. With unit running in heat mode, short the “TEST” terminal to the common terminal near it. This will speed up the board and cause it to enter defrost mode in 5/10/15 seconds depending on the defrost time selection. Compressor delay will not function during speed-up. 3. This test will end in 5 seconds if the “TEST”common short is not removed. 4.
