At the beginning of the defrost cycle, both the
outdoor condenser fan and compressor will
turn off. After approximately 30 seconds, the
compressor will turn on and begin to heat the
outdoor coil causing the ice and snow to melt.
NOTE: While the ice and snow is melting, some
steam may rise from the outdoor unit as the warm
coil causes the melting frost to evaporate. When
defrost is completed, the outdoor fan motor will
start, and the compressor will turn off again. In
approximately 30 seconds the compressor will
start up again and continue normal operation.
System Shutdown
Change the thermostat’s system mode to OFF
and the fan mode to AUTO (See Figure 1).
NOTE: The system will not operate, regardless
of the temperature selector setting.

Single packaged heat pumps are ready for easy
and immediate installation and can be readily
connected into the high static duct system of a
home. This unit is completely assembled, wired,
and run tested at the factory. This heat pump
is designed for outdoor installation only. The
only connections needed for installation are the
supply and return ducts, the line voltage, and
thermostat wiring. A complete heat pump system
typically consists of:
• Single Package Heat Pump
• Home Fittings Kit
• Unit Fittings Kit
• 2-Stage Cooling/Heating Thermostat
Use of components other than those specifi ed
may invalidate ARI Certifi cation, Code Agency
Listing, and limited warranty on the air
conditioner.
Pre-Installation Check
Before you install this unit, the cooling load of
the area to be conditioned must be calculated
and a system of the proper capacity selected. It
is recommended that the area to be conditioned
be completely insulated and vapor sealed.
The electrical supply should be checked to
determine if adequate power is available. If there
is any question concerning the power supply,
contact the local power company.
CAUTION:
To prevent personal injury and/or
equipment damage, check thermostat
manufacturer’s operation of fan relay
circuit when in EMER HEAT. When
the thermostat system mode is in the
EMER HEAT position, the thermostat
must energize the fan relay when the
fan mode is in the AUTO position.
Inspecting Equipment:
All units are securely packed at the time of
shipment and, upon arrival, should be carefully
inspected for damage. Claims for damage
(apparent or concealed) should be filed
