Selector (Upper Lever)
This lever provides a selection
of systems available to handle vari-
ous heating and cooling require-
ments throughout the year. The
positions of the Selector lever are
separated into four (4) major op-
erational groups, "Off," "Air Con-
ditioning," "Vent" and "Heating."
The "Air Conditioning" and "Heat-
ing" groups have several positions
which improve the effectiveness of
the system for various demands.
Fan
The fan lever has four (4) posi-
tions from Lo at the top to High at
the bottom. When the air condi-
tioning system is operating, low
blower will be maintained. (This is
to insure air flow over the cooling
coils to prevent a freeze-up.)

(If
the "Temperature" lever
is moved warmer, the system will
automatically go on outside air.)
The "Max" position is used when
maximum cooling is required un-
der conditions of high temperature
and humidity.
UNORMAL"-Outside
air is passed
through the system and discharged
through the AIC outlets. This po-
sition is recommended for most air
conditioning situations because of
reduced blower noise and reduc-
tion of cigarette smoke within the
vehicle.

mended for sunny cooler weather
where warm air is required on the
feet with cooler air above to pro-

comfortable breath level.
Temperature may be adjusted as
desired.
NOTE: This position will clear
fogged windows rapidly due to the
dehumidifying effect of the cooling
coils when the outside temperature
