Heater and Air Conditioning Controls
The recirculating fan controls air flow through the
louvers (see Figure 17). Knob B (see Figure 16)
selects one of three recirculating fan speeds or
the off position. Knob (B) also turns on the A/C
compressor in all positions except for off position.
Temperature Control
Rotate the temperature control knob (A) to control
the air temperature.
Heater
To increase air temperature move knob 3 mm (1/8
in.) into the red. Wait 3 to 4 minutes, allowing the
air temperature to stabilize, before repeating the
procedure if needed.
Air Conditioning
If maximum cooling is needed, turn temperature
control knob (A) to the maximum position in the
blue area and turn fan control knob (B) to the
fastest fan position. Lower the fan speed to medium
as the cab cools, then lower the fan speed to low
if necessary. Wait 3 to 4 minutes between adjust-
ments, allowing the air temperature to stabilize.
Move fan control knob (B) to the off position to turn
off the air conditioning.
