4.2.3 Air conditioning operation notes
Z
If there is a high level of air humidity in the truck, switch on the air conditioning
system. To distribute air evenly to all the discharge jets, set the fan switch (135) to
the highest level, set the temperature selector (134) as required and open the side
sliding window a notch. When the humidity has been removed from the interior of
the truck close the windows again and set the required air flow.
Z
To cool off the interior quickly, turn on the air conditioning system. To distribute air
evenly, open all the discharge jets. Set the fan switch (135) to the highest level and
open the side sliding window a notch. When the desired temperature has been
reached, close the windows again and set the required air flow.
Z
To guarantee maximum operation of the air conditioning system it must be switched
on in the cold season at least once a month for about 10 minutes (refrigerant needs
to be recirculated).
Z
When the air conditioning system is operating, condensation water may be visible
underneath the truck. This happens during the air dehumidification process, in
particular at high external temperatures and high air humidity.
CAUTION!
Regular servicing of the air conditioning system is required to ensure it can
work at a consistently high level, (see "Maintenance checklist" on page 144).
