Radios And Tape Deck - GMC Motor Home Operating Manual

"FAN"-the fan switch has four positions ;
"OFF" and three blower speeds ranging from
"LO" to "HI ." The fan will not operate unless
the top lever has been moved from the "OFF"
position, and in order to operate the fan in
the "HI" position the engine must be running.
"OFF," "A/C," "VENT," "HEATER," "DEF"
-With the lever in the "OFF" position the
system is off. With the lever in the "A/C"
position (and the "RECIRC," "COLD,"
"HOT" lever at "RECIRC" position) the air
conditioning system is activated. This posi-
tion uses 100% recirculated air. This setting
will provide maximum cooling . In combina-
tion with "A / C" setting moving the tempera-
ture lever to the "COLD" position provides
100% outside air. Further movement of the
temperature lever to the right (toward
"HOT" position) will heat the dehumidified
air to the desired temperature . The "FAN"
switch can be set to meet air
flow
require-
ments .
With the lever in the "VENT" position,
100% outside air enters the driver's com-
partment. This setting is for use during peri-
ods of less severe heat and humidity, air flow
is identical to air flow in "A/C" position, how-
ever, the air conditioning compressor is not
operating. Temperature of incoming air may
be controlled by moving the temperature
lever to the desired position . Any one of the
three blower speeds may be selected .
With the lever in the "HEATER" position,
air will flow through the heater floor dis-
tributor outlet (with a slight
flow
of air to the
defroster outlet) . For maximum heat, move
the temperature lever to "HOT" position and
"FAN" switch lever to "HI" position . Heating
system output can be varied by moving tem-
perature lever and "FAN" lever to different
positions.
With the lever in "DEF" position, system op-
erates the same as in the "HEATER" position
except most of the air
flow will
be through
the defroster outlets at the windshield .
"RECIRC," "COLD," "HOT" -This lever,
used in conjunction with the system selector
lever ("OFF," "A/C," "VENT," "HEATER,"
"DEF") and the "FAN" switch lever, will
control the temperature of the output air
being distributed .

CAUTION
Operate in "DEF" position for 30 sec-
onds before switching to "A/C." This
will
remove humid air from the system
and minimize rapid fogging of the glass
which can occur if humid air is blown
onto a cool windshield .
Clear windshield. rear window, outside mir-
rors, and all side windows of ice and snow
before driving vehicle.
Operate blower on "HIGH" for a few seconds
before moving the vehicle, to clear the air
intakes of snow .
