11.9.2 Air conditioning system
You can use the air-conditioning system to cool and dry the air in the crane cab.
Notes Do not cool the air in the crane cab too much.
The difference between the outside temperature and the inside temperature
should be at the most 10 °C to 14 °C (50 °F to 57.2 °F).
If the cooling is too severe, you may frequently feel physically uncomfortable,
albeit mostly only after you leave the cool environment.
Avoid having cold air blowing directly on to your body.
When using recirculated air, you should switch over to fresh air mode to ensure
a fresh supply of oxygen at the same time. Adjust the cooling output to your actual
needs:
If the truck crane has been exposed to strong sunlight for a long period of time,
for example, the air-conditioning system should initially be operated at the highest
blower level with the engine running.
The door or at least the windows should be left open for a short while to
thoroughly air the cab.
If the air-conditioning system is operated continuously, close the windows and
doors to ensure sufficient cooling.
Once the inside temperature has reached the desired temperature, set the fan to
a lower level.
