Cooling
1. Switch the air conditioning on.
2. Switch the recirculation to position 1, 2
or 3.
3. Turn the temperature control switch to
the desired position. For maximum
cooling set the knob to the far left
position in the blue area.
4. Open the side and center vents.
While heating, it is possible to use the air
conditioning to remove moisture from the
air in the cab. This has the advantage that
demisting of the window glass will be
quicker.
Dehumidification
1. Switch the air conditioning on.
2. Turn the Fan Speed Switch to the
Fresh Air setting.
3. Open the vents on the center console
and side windows and set them as
desired.
4. Control the temperature as desired.
5. Adjust the volume of air using the fan
speed selector switch.
NOTE
The air conditioning system is switch-
ed off when the engine coolant tem-
perature becomes too high. This will
protect the engine.
WARNING
Excessive heat may cause the pres-
surized components of the air condi-
tioning system to explode. Never weld,
solder, steam clean, or use a blow
torch near any part of the air condition-
ing system. Failure to comply may re-
sult in personal injury, death, equip-
ment or property damage.
WARNING
Air conditioning refrigerant can be haz-
ardous to your health. Do not expose
yourself to leaking refrigerant for pro-
longed periods near excessive heat,
open flames, or without proper ventila-
tion. Failure to do so may result in
death or personal injury.
NOTE
If the air conditioning system fails to
work properly, it must be repaired by
qualified personnel as soon as possi-
ble, to avoid further damage to the
system.
Fan Speed Selector Switch
Fresh Air Position or Re-Circulation
Position
The fan has two speeds: one applies to re-
circulation the other to fresh air. The
recirculation position is suited to quickly
de-mist or cool the cab with the air
