NORMAL SEQUENCE OF OPERATION

NOTE: There is a fan delay on initial power to unit before the low voltage board resets and is operational.

1.Thermostat calls for heating or cooling. The compressor and outdoor fan are energized.

2.Approximately 10 seconds later, the indoor fan starts.

3.The unit will deliver heating or cooling to the conditioned space until the thermostat is satisfied.

NOTE: PHD60 TWO-STAGE COOLING

If the room temperature is 4°F higher than thermostat setpoint, the indoor fan will run at high speed, and the compressor at full load. If the room temperature is within 2°F of thermostat setpoint; the indoor fan will shift to low speed and the compressor will unload to a lower capacity.

4.The compressor and outdoor fan will be de-energized when the thermostat opens.

5.The indoor fan continues to run for approximately 60 seconds after the thermostat is satisfied. This allows additional cooling from the indoor coil to be transferred to the conditioned space. Then, the indoor fan stops.

STARTUP AND ADJUSTMENT

WARNING

TO PREVENT PERSONAL INJURY OR DEATH, ALWAYS DISCONNECT THE ELECTRICAL POWER BEFORE INSPECTING OR SERVICING THE UNIT. SINCE ALL OF THE COMPRESSOR PROTECTION DEVICES RESET AUTOMATICALLY,

THE CONTACTOR AND OUTDOOR FAN MAY BE ENERGIZED WHEN RESET.

WARNING

THIS UNIT MUST NOT BE USED AS A "CONSTRUCTION HEATER" DURING THE FINISHING PHASES OF CONSTRUCTION ON A NEW STRUCTURE. THIS TYPE OF USE MAY RESULT IN PREMATURE FAILURE OF THE UNIT DUE TO EXTREMELY LOW RETURN AIR TERMPERATURES AND EXPOSURE TO CORROSIVE OR VERY DIRTY ATMOSPHERES.

COMPRESSOR PROTECTION DEVICES

This package heat pump unit compressor includes components which are designed to protect the compressor against abnormal operating conditions.

OPERATING INSTRUCTIONS

1.Turn ON the electrical power supply to the unit.

2.Place the room thermostat selector switch in the COOL or HEAT position (or AUTO if available, and if automatic changeover from cooling to heating is desired).

3.Set the room thermostat to the desired temperature.

MAINTENANCE

WARNING

TO AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRICAL SHOCK, DISCONNECT ELECTRICAL POWER BEFORE PERFORMAING ANY MAINTENANCE.

REPLACING OR CLEANING FILTER

A return air filter is not supplied with this unit; however, there must be a means of filtering all of the return air. The filter(s) may be located in the return air duct(s), or return air filter grille(s). Consult with your installing dealer for the actual location of the return air filter(s) for your unit.

Dirty filters are the most common cause of inadequate heating or cooling performance. Filter inspection should be made at least ev- ery two months; more often if necessary because of local conditions and usage.

Dirty throwaway filters should be discarded and replaced with a new, clean filter. Dirty permanent filters should be washed with water, thor- oughly dried and sprayed with a filter adhesive before being rein- stalled. (Filter adhesives may be found at many hardware stores.) Permanent filters should last several years; however, should one become torn or uncleanable, it should be replaced.

MAINTAINING CABINET FINISH

Use a fine grade automotive wax on the cabinet finish to maintain the finish’s original high luster. This is especially important in areas with high ultraviolet radiation.

CLEAN OUTSIDE COIL (QUALIFIED SERVICER ONLY)

The coil with the outside air flowing over it should be inspected an- nually and cleaned as frequently as necessary to keep the finned areas free of lint, hair and debris.

CONDENSER AND EVAPORATOR MOTORS

Bearings on the evaporator motor and the condenser motor are per- manently lubricated. No additional oiling is required.

WARNING

TO AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRIC SHOCK, DO NOT REMOVE ANY INTERNAL COMPARTMENT COVERS OR ATTEMPT ANY ADJUSTMENT.

CAUTION

ALWAYS VERIFY PROPER OPERATION AFTER SERVICING.
