Heating & Cooling
Heating & Cooling
This following section contains an overview of the original
factory-installed heating and cooling components. For more
information on each specific component, please refer to the
manufacturer’s operating instructions found in your Owner
Information Package.
If there have been modifications or replacements made to your
RV, then these instructions may not apply. Please contact the
service center or technician who performed the modifications
or substitutions if assistance is required.
Air Conditioner
Your thermostat controls the roof-mounted air conditioning
system equipped on your RV. ALWAYS check that you have
sufficient power available before operating the air conditioner.
Cooling vs. heat gain
The roof air conditioner can, at best, cool the air it intakes by
20 ° F. During hot weather, through the day, your RV will absorb
heat, increasing the inside temperature. This is referred to as
heat gain .
To keep the inside temperature comfortable, reducing heat
gain of the RV is just as important as the cooling ability of your
air conditioner. To reduce heat gain, follow these steps:
1. Park the RV in a shaded area.
2. CLOSE the blinds or drapes.
3. Use the awnings to shade your RV from sun exposure.
4. Avoid the use of heat producing appliances.
5. SET the air conditioner
Fan/Cooling mode
to HIGH.
In high humidity or high temperatures, this will provide
maximum efficiency.
6. Turn ON the air conditioner early in the morning,
to give it a head start on cooling.
Do not operate the air
conditioner without the
Return Air Filter. Operation
without the filter allows lint
and dirt normally stopped
by the filter to accumulate
on the air conditioner's
cooling coil. This will lead
to a loss of air volume,
possible equipment
damage and an expensive
cleaning process.
