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.

WARNING
T
HIS UNIT MUST NOT BE USED AS A "CONSTRUCTION HEATER" DURING THE
FINISHING PHASES OF CONSTRUCTION ON A NEW STRUCTURE.
T
HIS 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

3. Set the room thermostat to the desired temperature.
MAINTENANCE
WARNING
T
O 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
T
O AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRIC SHOCK, DO NOT
REMOVE ANY INTERNAL COMPARTMENT COVERS OR ATTEMPT ANY
ADJUSTMENT.
