Air Conditioning Comfortron System-119.0" W. B. Station Wagons
Comfortron Air Conditioning adds
the convenience of completely auto-
matic control to the combined heating
and cooling functions of the Four-
Season system, automatically main-
taining the selected inside temperature
regardless of the season or outside
weather conditions.
During warm weather, cooled, de-
humidified air enters the car through
the three dash outlets. During cold
weather, heated airflow will enter the
car through the floor distributor duct.
Control Panel
The control panel makes use of a
temperature dial and a single control
lever.
Temperature Dial
This
dial,
numbered 1 through 5,
may be set once to the desired tem-
perature, much as your home ther-
mostat, and normally need not be
adjusted thereafter. The higher the
number the warmer the temperature
-with number 3 being the optimum
temperature setting. The system will
run at increased capacity until the
pre-set temperature is reached. Fur-
ther movement of the temperature
dial will not decrease the time needed
to bring the car to this temperature.
However, since individual comfort
requirements vary considerably, you
may wish to vary the dial setting
slightly to compensate for warmer or
cooler weather.

Control Lever
In the OFF position, the system is
turned off and no air enters the car.
However,
it is not necessary to turn
the system to OFF when leaving the
car. It will then operate automatically
whenever the car is started.
During warm weather the system
will go into operation almost immedi-
ately, but cold weather operation will
be delayed until the engine warms up
enough to supply heat to the
system.
In
cold weather, immediate blower oper-
ation can be obtained in the DE-ICE
position.
Normal Operation-Set the lever to Lo
for completely automatic in-car tem-
perature control. This setting allows
the system to utilize five blower
speeds, resulting in low to moderate
airflow.
When greater airflow is desired or
in severe weather
extr
emes, set the
lever
to
Med or Hi. The system, still
under automatic control, will now
make use of five higher blower speeds
