13.6.3 Bleeding the heating system
The bleeding valves are built in nearby the radiators.
 Switch off the hot-water heater and allow it to cool down.
 Open the bleeding valve (Fig. 168,1) and leave it open until no more air escapes.
 Close bleeding valve.
 Repeat this procedure at all bleeding valves.
 Check to see if the hot-water heater warms up.
13.7 Air conditioning unit
A lint filter (Fig. 169,1) for the air circulation suction system is located at the rear of
the air conditioning unit. The lint filter must be cleaned at regular intervals, at least
twice a year however, and replaced if necessary.
Pull the lint filter out of the air conditioning unit, clean it or replace it if necessary.
The condensation drain is under the floor of the vehicle. Keep the drain hose free
from dirt, leaves or similar to allow the condensation to be drained.

X Prior to carrying out work on the device, turn off the power supply.
Z Never operate the air conditioning unit without a lint filter. Without a lint filter
the evaporator becomes soiled, resulting in the performance of the air condi-
tioning unit being impaired.
Z If the condensation drain is clogged, condensate can enter the vehicle. Keep the
condensation drain free of dirt, leaves and similar obstacles.
