AIR CONDITIONING SWITCH
The cab air can be heated, cooled or dehumidified using the air conditioning unit.
The air conditioning unit only functions if:
- the engine is running
- the fan is running.
Use of the air conditioning
1. When the air conditioning is in use, the windows must remain closed.
2. To reduce the temperature quickly, first use maximum air speed. Later, the air
speed can be reduced.
3. Avoid direct cold draught on your body.
4. Make sure that the temperature difference between the inside and outside of the
cab does not exceed 40°F (5°C) when you leave the cab. You are therefore
advised to switch off the air conditioning towards the end of your journey.
5. Air conditioning consumes extra power and increases the fuel consumption.
6. On extreme angles (slopes, ruts and difficult terrain) switch off the air
conditioning, to protect the compressor pump against unlubricated operation.
7. Regularly (once a month) switch on the air conditioning briefly, even if cooling is
not required (e.g. in winter). This will help prevent serious damage to the system
(including compressor blockage).
