ROOF AIR CONDITIONING -
WITH HEAT PUMP
–If Equipped
Your coach may be equipped with an air
source heat pump built into the air conditioning
system. Because the heat pump operates on
electricity, it provides economical heat inside
your coach and helps reduce the use of propane
gas for heating in cooler weather.
A heat pump can be thought of as an air
conditioner running in reverse. An air
conditioner absorbs heat from the air on the
inside of the coach and moves it to the outside.
The heat pump does exactly the opposite. Even
cold air contains some heat, so a heat pump will
extract heat from the outside air on a cold day and
carry it to the inside of the coach to maintain a
comfortable temperature.
The efficiency of a heat pump decreases as the
outdoor air temperature drops, so supplementary
heat is often needed when the outside
temperature nears freezing. The heat pump will
not operate when the outside temperature falls
below 36 degrees F.
To operate the heat pump
•
Turn the selector switch to the “High Heat”
position, which allows the fan to operate at
high speed with maximum heat output.
•
Rotate the temperature control switch to the
position that is the most comfortable to you.
When the temperature of the air entering the
air conditioning unit drops below this setting
a few degrees, the thermostat will turn the
compressor/heater on. It will automatically
turn off when the temperature of the air
entering the air conditioner rises a few degrees
above this setting. The compressor/heater will
continue to cycle on and off until the selector
switch is turned to another operation mode.
Check your Air Filter
Closed or blocked vents and a dirty air filter
can hinder the efficiency of a heat pump.
•
Be sure ceiling vents are open to distribute
heat pump output air.
•
The A/C return air filter should be checked
monthly for dirt build-up and cleaned or
replaced as needed. See “Air Conditioner
Filter” elsewhere in this section.
Further Information
See the air conditioning/heat pump
manufacturer’s information in your InfoCase for
complete operating instructions.
