1. Fan
Turn the control
(1)
clockwise for higher fan speed and adjust the control to the desired speed. The
blower fan switch has five positions: OFF, 1, 2, 3, and 4. Turn the switch to 4 for maximum speed and
to 1 for the lowest speed. Turn completely counterclockwise for OFF.
2. Air-conditioning
Operate the control
(2)
to set one of the two positions:
OFF
ON - Air-conditioning
3. Climate control
Turn the control
(3)
clockwise, and adjust the control
(3)
to the desired temperature. Blue markings
indicate cooler temperatures. Red markings indicate warmer temperatures when using the heater.
NOTE:
make sure the water inlet for the heater is in the full ON position. This inlet is located in the
left-hand rear of the engine compartment.
NOTE:
during some conditions, it is possible to have ice on the air-conditioning core. Operating at the
maximum cold setting of the air-conditioning control with the blower speed at low can cause ice. It is
best to operate air-conditioning at the center range of the temperature control with the blower speed at
medium or high. Another cause of ice can be a restricted air filter in the cab.
