11.3.4 Odour seal
In order to prevent odours occurring in the waste water system, the vehicle -
depending on the model - has been equipped with odour seals (Fig. 157,1).
The odour seals are installed in the waste water pipes.
Clean the odour seals every two years at the latest. To do so, unscrew and
remove the bottom cover (Fig. 157,2).
11.4 Filling the water system
Position the vehicle horizontally.
Connect the 240 V power supply and switch on the 240 V automatic circuit
breaker.
Switch on the 12 V main switch on the panel (Power Pack SE).
Close drain cocks for the boiler and hot water source.
Close all water taps.
Establish the external water connection.
Fill the water tank with fresh water. Use a water hose, a water canister with
a funnel or similar for filling.
Set all the water taps to "Hot" and open them. The water pump is turned on.
Keep the taps open until the water flowing out of the taps has no bubbles
in it. This is the only way to ensure that the hot water source or the boiler
is also full of water.
Set all water taps to "Cold" and leave them open. This will fill the cold water
pipes with water.
Keep the taps open until the water flowing out of the taps has no bubbles
in it.
Close all water taps.
Check that the cap on the water tank is not leaking.
11.5 Emptying the water system
Fig. 157 Odour seal
The water pump will overheat without water and can get damaged. Never
operate water pump when the water tank is empty.
If the vehicle is not heated when there is risk of frost, empty the entire water
system. Leave the water taps on in central position. Leave all drain cocks
open. This will avoid frost damage to appliances and to the vehicle.
