Heat Pump Operation (Optional)
Heat Pump mode offers heat
by using the air conditioner as a
heat source. The air conditioning
principle is reversed, supplying
heated air to the ceiling registers
instead of refrigerated air.
There are ambient temperature
limitations in Heat Pump mode.
NOTE:
The roof air conditioner will not
operate in Heat Pump mode with
ambient temperatures at or below
30º F.
Aux Heat Mode:
If the Heat Pump mode is selected at or
below 30° F, or if operating in Heat Pump
mode and temperature drops to 30º F, the air
conditioner will stop Heat Pump operation and
Aux Heat will display. The furnace will be
selected as the auxiliary heat source and will
begin operation. The furnace will remain the
primary heat source until ambient temperature
rises abobe 42º F.
When ambient temperature is between
30 and 42º F, a defrost cycle is initiated
approximately every 40 minutes of compressor
operation. The blower motor will stop for ve
minutes and Defrost will be displayed. After
the defrost cycle the heat pump operation will
resume.

Return Air Filters
Frequently clean the return air lters. The
lter are located inside the air conditioner
behind the intake vent covers. To access the
lters, rmly grasp the leading edge and push
back on both tabs. Never run the air conditioner
without the return air lters in place. Dust and
other particles will plug the evaporator core and
substantially reduce the performance of the air
conditioners.

NOT use solvents.
Rinse lters thoroughly with fresh water.
Allow them to dry.
Install lters and secure the intake vent
