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.
HEAT PUMP MAINTENANCE
CAUTION:
Shut off all electrical power to the unit before
performing any maintenance. Failure to comply
may result in personal injury or death.
Proper maintenance is most important to achieve the best
performance from the appliance and should be performed
by a qualifi ed service technician at least once a year. Read
the maintenance items below and follow the instructions
for years of safe, trouble free operation.
Regular Cleaning
WARNING:
Do not place combustible material on or against
the unit cabinet. Do not place combustible
materials, including gasoline and any other
fl ammable vapors and liquids, in the vicinity of
the unit.
•
Clean or replace the indoor air fi lter at the start of each
heating and cooling season, and when an accumulation
of dust and dirt is visible on the air fi lter.
• Remove any leaves and grass clippings from around
the coil of the outdoor unit, being careful not to damage
the aluminum fi ns.
• Check and remove any obstructions, such as twigs,
sticks, etc.
TROUBLESHOOTING
If the unit fails to operate, check the following:
•
The thermostat is properly set. See Cooling Operation
for air conditioning or Heating Operation for furnace.
•
The unit disconnect fuses are in good condition and
the electrical power to the unit is turned on.
WARRANTY INFORMATION
A warranty certifi cate with full details is included with the
heat pump. Carefully review these responsibilities with
your dealer or service company. The manufacturer will not
be responsible for any costs found necessary to correct
problems due to improper setup, improper installation,
adjustments, improper operating procedure on the part
of the user, etc. Some specifi c examples of service calls
which are not included in the limited warranty are:
•
Correcting wiring problems in the electrical circuit
supplying the heat pump.
•
Resetting circuit breakers or other switches.
•
Adjusting or calibrating of thermostat.
Operating the 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:
Thermostat styles vary. Some models will
not include the AUTO mode and others will have the
AUTO in place of the HEAT and COOL. Others may
include all three. Refer to the instructions supplied
with your thermostat for specifi c instructions.
2. Set the thermostat temperature to the desired
temperature level. The outdoor unit and the indoor
blower will then cycle on and off in either the heating or
cooling mode of operation as required to automatically
maintain the indoor temperature within the desired
limits.
Operating the Indoor Blower Continuously
The continuous indoor blower operation is typically used to
circulate the indoor air to equalize a temperature unbalance
due to a sun load, cooking, or fi replace operation.
Set the thermostat fan mode to ON (Figure 1). The indoor
blower starts immediately, and will run continually until
the fan mode is reset to AUTO.
The continuous indoor blower operation can be obtained
with the thermostat system mode set in any position,
including OFF.
Shutting the Heat Pump Off
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.
