13.3.3 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 bleeding valve (Fig. 244,1) and leave 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.
13.4 Independent vehicle heater
Use the independent vehicle heater for 10 minutes at least once a month with
a cold engine and smallest fan settings.
Before the heating season starts, have the independent vehicle heater
checked by an authorised specialist workshop.
13.5 Air conditioning unit
Fig. 244 Bleeding valve of hot-water
heater
Prior to carrying out work on the device, turn off the power supply.
Never operate the air conditioning unit without a lint filter. Without a lint
filter, the vaporiser becomes dirty and the capacity of the air conditioning
unit is consequently impaired.
Condensation can enter the vehicle if the condensation drain is clogged up.
Keep the condensation drain free from dirt, leaves and similar.
