UCTING ETURN
All heat discharges, registers and return air grills must be free and clear of
obstructions. This includes all closeable registers that are intended to reduce
airflow, do not shut it off completely.

The 12-volt DC attic fan (or powered roof vent) allows fresh air to circulate through
the motor home. Do not leave the attic fan open when the motor home 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.

There may be up to two 12-volt DC thermostats in your motor home. Use the
controls to set the temperature to your comfort setting.

IR ONDITIONER
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.

URNACE
The furnace installed in your motor home is controlled by a thermostat. The
furnace requires both 12-volt power and propane gas for full operation. Make sure
you have sufficient power available before operating your furnace
If you have any questions contact your dealer or Jayco Customer Service.
