Your motor home has a roof mounted air conditioning system that is controlled by a
thermostat. Cooled air enters the motor home through the adjustable "chill 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 equipment damage and an
expensive cleaning process.
A special foam gasket is placed between the roof material and the subframe of the air
conditioner 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 tightness
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.
Heat pump operation
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.

The 12-volt DC attic fan (or powered roof vent) allows fresh air to circulate through the
recreation vehicle. Do not leave the attic fan open when the recreation 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. You will receive
the greatest airflow comfort by positioning yourself between the
window and the fan.
For additional information refer to the manufacturer's owner's
manual included in your warranty packet.
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.
