If the vehicle will not be used for more than 6 months, the following measures have to be taken:
13.1 Draining the fresh water tank

Drain the fresh water tank ( see item 5.7 “ Draining the fresh water tank ” ).
●
Clean and disinfect, if possible.
13.2 Draining the cold and hot water
●
Also see item 5.13 “Draining the boiler”.
●
Switch off the fresh water pump for this, turn all outlets (mixer taps) to the central open position
and place the shower hose downwards. Once the water has drained, switch on the fresh water
pump again for 20 seconds while flushing the toilet. This ensures that no water remains in the sys-
tem. Switch off the fresh water pump.

Drain and clean the waste holding tank (cassette). ( See item 9.6 “ Draining the waste holding tank (cassette) ” )
Environmental contamination due to inexpert disposal
Only dispose of waste water at the waste disposal points provided specifically for this
purpose.
Note: The drain valves of the fresh water tank and waste water tank as well as the toilet
slide valve should remain open while the vehicle is laid up to enable air circulation and
prevent odours from forming.
