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). 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.
TO SHUT OFF YOUR HEAT PUMP —
Set the thermostat system switch to OFF and
the thermostat fan switch to AUTO. (See Figure
1) The system will not operate, regardless of the
thermostat temperature selector(s) setting.
TO OPERATE THE INDOOR BLOWER
CONTINUOUSLY —
Set the thermostat fan switch to ON (See Figure
1). The indoor blower will start immediately, and
will run continually until the fan switch is reset
to AUTO.
The continuous indoor blower operation can be
obtained with the thermostat system switch set
in any position, including OFF.
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 fireplace operation.
TO MAINTAIN YOUR HEAT PUMP —
CAUTION:
Make sure the electrical power to the
outdoor unit and the furnace/air handler
is disconnected before doing the
following recommended maintenance.
1. Regularly:
a. Clean or replace the indoor air filter at the
start of each heating and cooling season,
and when an accumulation of dust and dirt
is visible on the air filter. Inspect the filter
monthly.
b. Remove any leaves and grass clippings from
the coil in the outdoor unit, being careful
not to damage the aluminum fins.
c. Check for any obstruction such as twigs,
sticks, etc.
CAUTION:
Do not over-oil, or oil motors not
factory-equipped with oil tubes. The
compressor is hermetically “sealed”
and does not require lubrication.
2. Before Calling a Service Technician, Be
Certain:
a. The unit thermostat is properly set — see
“To Operate Your Heat Pump for Cooling”
and “To Operate Your Heat Pump for
Heating.”
b. The unit disconnect fuses are in good
condition, and the electrical power to the
unit is turned on.
