OFF
OFF - The blower motor does not operate. The fresh air inlet door will
close minimizing outside air infiltration into the the motorhome.
BI-LEVEL - Fresh air is drawn in and discharged through the dash, floor
and defrost louvers.
FLOOR - Fresh air is drawn in and discharged through the floor louvers. A
small amount of air is used to defrost the windshield.
MIX - Fresh air is drawn in and discharged through the floor 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 system operates to dehumidify the discharged air.
Temperature Control Switch:
This switch controls an electric water valve regulating the amount of
engine coolant passing through the heating and cooling coils in the system.
Rotating to the red area provides warmer air; rotating to the blue area provides
cooler air.
Blower Control Switch:
The switch controls the speed of the blower motor, which is one of the best
and most effective ways of controlling the temperature. The switch provides
four speeds in all modes except OFF.
Operating tips and hints:
Air intake and discharge temperatures are greatly effected by ambient
temperatures and relative humidity. A large amount of cooling capacity is used
to dehumidify air as well as cool it. After three to five minutes of A/C opera-
tions, the discharged air temperature should be approximately 30º F cooler
than the fresh or recirculated air entering the AC system.
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 will provide quick cool down.
• Use a lower blower speed to produce cooler air.
