Mode Control Switch: Directs air ow by
opening or closing damper doors. Use the Mode
Control Switch to direct airow where it is
needed to maximize comfort in the cockpit area.
NOTE
The air conditioning compressor is
activated when using MAX A/C, A/C,
MIX and DEFROST.
MAX A/C - Recirculated air is
drawn from the passenger area
and discharged through the dash
louvers.
A/C - Fresh Air is drawn from
outside into the system and
discharged through the dash
louvers.
VENT - Fresh air is drawn in
and discharged throughout the
dash louvers.
OFF - The blower motor does
not operate. The fresh air inlet
door will close, minimizing
outside air inltration into the
motorhome.
BI-LEVEL - Fresh air is drawn
in and discharged through the
dash and the oor louvers.
FLOOR - Fresh air is drawn in
and discharged through the oor
louvers.
MIX - Fresh air is drawn in and
discharged through the oor and
defrost louvers. The A/C system
operates to dehumidify the
discharged air.
DEFROST - Fresh air is drawn
in and discharged through
the defrost louvers. The
A/C compressor operates to
dehumidify the discharged air.
A/C Operation: When the Mode Control
Knob is positioned in the A/C mode, fresh air
is drawn through the front air intake of the unit
through the A/C coil. The Mode Control Knob in
the MAX A/C position closes off a damper door
to outside air and recirculates air from inside the
motorhome. Select this position when maximum
cold air is desired or to keep outside air from
entering the motorhome.
NOTE
Activate the A/C system monthly to keep
internal components of the compressor
lubricated.
Heat and Defrost Operation:
Set the Mode Control Switch to the
desired position.
Set the Temperature Control Switch to
the red zone.

Operating Tips & Hints
Air intake and discharge temperatures are
greatly affected by ambient temperatures and
relative humidity. A large amount of cooling
capacity is used to dehumidify as well as
cool air. After three to ve minutes of A/C
operations, discharged air temperature should be
approximately 20º to 30º F. cooler than the fresh
or recirculated air entering the A/C system.
At the beginning of the day, activate the
compressor with the engine at idle. This will
avoid sudden high speed activation resulting
in possible damage from lack of internal
compressor lubrication.
Winter Use:
De-ice the windshield using the
DEFROST mode.
Air will heat up faster with a slower
blower speed until normal operating
temperature ranges are reached.
Summer Use:
Close all windows and vents to hot,
humid outside air.
MAX A/C and HI blower provides quick
cool down.
Use a lower blower speed to produce
cooler air.
Temperature Control switch must be set
to the blue zone for cool air.
