4.10.2 AIR CONDITIONER
The motorhome is equipped with a roof
mounted air conditioner to cool the interior of
the motorhome while it is occupied. An
optional heating strip is also available.
1. Master Fan Control:
a. Off:
This position turns the power to the
system off.
b. Fan:
These 3 positions (high, medium and
low) set the fan speed to draw
outside air into the coach.
c. Optional Heat:
This position draws heated air into
the interior and is not meant to
replace a furnace but just to remove
the chill.
d. Cool:
These 3 positions control the fan
speed that draws cooled air into the
coach.
2. Cooling Temperature:
This switch sets the thermostat that
controls the power to the compressor in
the air conditioning system. The lower
the temperature is set, the more fre-
quently the compressor will engage for
cooling.
