If the Heat Pump mode is selected at or below 24° F., or if operating in
Heat Pump mode and temperature drops to 24º F., the air conditioner will stop
Heat Pump operation and Aux Heat will be displayed. 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 above 42º F.
When ambient temperature is between 24 - 42º F., a defrost cycle is initiated
approximately every 40 minutes of compressor operation. The blower motor will
stop for five minutes and Defrost will be displayed. After the defrost cycle the
heat pump operation will resume.
Heat Pump Operation:
• Battery cut-off switch must be in the ON position.
• Slide the ON/OFF switch to the ON position.
• Press the MODE button repeatedly until Heat Pump is
displayed.
• Set desired fan speed by pressing the FAN button.
• Press the UP or DOWN buttons to set desired heating temperature.
Clean the return air filters frequently. The filters are located inside the
motorhome behind the intake vent covers. The covers hinge on the curbside
with fasteners securing the roadside in place. Hook and loop strips hold the
filters in place. Never run the air conditioner without the return air filters in
place as this may plug the evaporator core with dirt and substantially affect the
performance of the air conditioner.
To Clean:
• Wash filters in warm soapy water. Do not use solvents.
• Rinse filters thoroughly with fresh water. Allow them to dry.
• Install filters and secure the covers.
The furnace and its related components are 12 Volt DC operated, using LP-Gas
as the fuel source. Electronic circuitry (automatic ignition) is used to ignite the
burner. The furnace uses outside air for the burner combustion and exhaust is
expelled through the outside vent. Inside air is drawn into the furnace and
blown across the internal heat exchanger. Heated air is then discharged through
ducted hoses which can be run throughout the motorhome. A warm air discharge
is incorporated to heat the holding tanks in the motorhome.
CAUTION: Do not store any items/materials in furnace area. Restricted
air flow may hamper furnace operation leading to failure and/or fire
hazard.
