Button
The button inside the
temperature control dial
engages the A/C
compressor. When
activated the indicator
on the button will
illuminate. During AUTO
mode, the A/C button
indicator will remain
illuminated at all times
even though the
compressor may be
cycling.
NOTE
Fan Control Dial must also be in the ON po-
sition for A/C to be on. A/C engages auto-
matically in AUTO, defrost and floor/defrost.
The air conditioner defaults to Manual
mode when turned on. The fan speed, air
temperature, and air outlets are selected
using the dials on the controller.
1. To adjust the fan speed, turn the fan
control dial clockwise to increase
speed or counterclockwise to
decrease speed. Setting the fan dial
to "O" turns the HVAC system off.
2. To adjust the temperature setting,
turn the temperature control dial to
the desired temperature. The
system automatically adjusts the
outlet air temperature to achieve the
desired cab temperature.
3. Push the snowflake button if the air
temperature needs to be colder, this
button will manually turn on the
compressor.
4. To adjust the air distribution, turn the
air distribution dial to the desired
position as indicated by the
graphics.
5. Select the recirculation button for
FRESH or RECIRC air.
The temperature of the air from the vents
will fluctuate as the vehicle works to
achieve the chosen cab temperature.
When idling for short periods of time, keep
the fan ON and set the air mode to FRESH
air. For vehicles with a sleeper, the cab
control can be used to activate/deactivate
the sleeper HVAC using the button inside
the mode dial.
Dash Switches
This custom vehicle will have a wide
variety of switch controlled equipment.
However, this particular vehicle may not
have every switch identified in this section
of the operator manual. Some air device
switches on the dash may require that the
vehicle either be at a specific speed, park
brakes set or another device to be on or off
for the air device to operate. The
instrument display will display information
regarding what needs to change in order
for the air device to operate as expected.
The following table provides a complete list
of icons that may be found on the switch.
