resulting in moderate to high air-
flow for rapid cool down or heating.
Blower speeds will decrease as the
temperature approaches the dial set-
ting.
Bi Level Operation
On cool but sunny days the Comfor-
tron system will provide warm air to
the floor and cooler air out of the upper
outlets thus providing a warm floor
without excessive rise in breath level
temperature. Under extremely bright
sun conditions, the system may shift
into bi-Ievel operation at relatively
low outside temperatures in order to
maintain the temperature set on the
dial. If cool air from upper outlets is
objectionable, adjust upper outlets as
desired.
Four Season System and
Comfortron Conditioned
Air Outlets
The twin barrel type center outlet
may be rotated or vanes turned to di-
rect air flow in direction desired. The
four position lever controls the vol-
ume of air through the center outlet.
The vertical outlets at each end of
the instrument panel may be rotated
or vanes adju'sted as desired. Push-
pull knob located on each side kick
pad control airflow to upper side
outlets.
For additional airflow lap coolers
(2) are provided under the steering
column and glove box. They have
vertical air control vane outlets and
are aimed at the driver and passenger
lap locations. Under each lap cooler is
a floor cooler outlet that is operated
in a push-pull manner for opening and
closing, controlling the amount of air
to the floor.
For window defogging - Move the
lever to DEFOG to divert a portion of
the conditioned air through the de-
froster ducts when interior window
fogging is encountered.
For windshield de-icing - With the
lever in the DE-ICE position the sys-
tem directs the entire airflow at full
heat and high blower speed through
the defroster ducts.
Air-Conditioner Operating Tips
~==================
Close all windows and vents when
operating air system except for the
first few minutes of operation when
the car interior is very hot. Close the
windows as soon as the excessively
heated air has escaped.

CAUTION: Operate system for 30 seconds
before switching
to
"DE-ICE". 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.
