Section 9: Heating & Cooling
Air Conditioner
The air conditioning system is controlled by a thermostat. Cooled air enters the RV through
the grill. Make sure you have sufficient power available before operating the air conditioner.
Do not operate the air conditioner without the return air filter. Operating the system without
the filter allows the lint and dirt that is normally stopped by the filter to accumulate on the
cooling coil of the air conditioner. This also will lead to a loss of air volume, possible equip-
ment damage and an expensive cleaning process.
Roof Mount (if so equipped)
A special foam gasket is placed between the roof material and the subframe of the air con-
ditioner to guard against water leakage. The air conditioner is subjected to wind pressures
along with motor vibration during normal operation. Inspect the mounting bolts for tight-
ness to ensure there is no leakage or looseness at least annually. Re-tighten bolts when
they are loose.
DO NOT
over tighten these bolts as it may damage this gasket. The air
conditioner gasket is a wearable part that eventually will need to be replaced. To gain access
to the bolts, remove the filtered panel cover on central air systems or the entire air box on
non-central air conditioners.
Wall Mount (if so equipped)
Keep the air inlet grill and cabinet clean by wiping with a cloth dampened with warm water
and a mild detergent.
Heat Pump Operation (if so equipped)
Set the thermostat for either electric or gas heat. On the electric setting, the heat pump
will become the primary heat source as long as the interior temperature of the RV has not
dropped 5° below the thermostat set point. If this occurs, the thermostat will automatically
activate your gas furnace.
The furnace will continue as the heat source until the thermostat set point has been satisfied.
At that point, the heat pump will again become the primary heat source.
For RV models with a touch screen system, the heating cooling controls are included on the
touch screen selectable screens.
For additional information
refer to the manufacturer’s owner’s manual included in your
warranty packet or consult your dealer.
Power Roof Vent (if so equipped)
The 12-volt DC attic fan (or powered roof vent) allows fresh air to circulate through the
recreational vehicle. Do not leave the attic fan open when the recreational vehicle is stored
or unattended for long periods.
High winds, other unusual conditions or obstructions may prevent the dome from closing;
the resulting leakage could cause non-warrantable damage.
To use your fan most effectively, close all vents and slightly open a window on a shaded side
of your recreation vehicle. You are directing the air flow by opening
a window.
For additional safety and operating information
refer to the man-
ufacturer’s owner’s manual.
Control pad (if so equipped)
The attic fan may be controlled by a control pad. The dome can be
raised or lowered with the UP/DOWN buttons, and the speed of the
fan is controlled by the ARROW buttons. It is also equipped with a
rain sensor that will close the vent automatically when it rains. The
rain sensor can be turned on/off by holding the DOWN button for
3 seconds.
