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.

Operating the Heat Pump for Automatic 
Cooling and Heating

1. Set the thermostat system mode to AUTO and the 

thermostat fan mode 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 specific instructions.

2. Set the thermostat's temperature selector 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.

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 fireplace 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.

HEAT PUMP MAINTENANCE

Proper maintenance is most important to achieve the best 

performance from the appliance and should be performed 

by a qualified service technician at least once a year. 

Follow the maintenance schedule and the instructions

Regular Cleaning

 

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.

•  Remove any leaves and grass clippings from the coil 

in the outdoor unit, being careful not to damage the 

aluminum fins.

•  Check for obstructions, such as twigs, sticks, etc.

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 or 

air handler.

•  The unit disconnect fuses are in good condition and the 

electrical power to the unit is turned on.
