To empty and ventilate the water system, proceed as follows. This will avoid
frost damage:
Position the vehicle horizontally.
Switch off 230 V power supply.
Switch off the 12 V power supply on the panel.
Shut off the boiler (see section 9.2).
Open the drain cocks. To do so, turn the cap in an anticlockwise direc-
tion or set the rocking lever in a vertical position.
Open the safety/drainage valve (Truma). To do this, turn the knob paral-
lel to the safety/drainage valve.
Open the water tank drain.
Open all water taps and set to the central position.
Hang the shower handset up in the shower position.
Unscrew the lock ring on the water tank.
Take water pump (fitted to the cover) as far as the connecting lines al-
low.
Hold the water pump up until the water pipes are completely empty.
Check whether the water tank is completely empty.
Set the shower handset down in the shower tray.
Blow out the remaining water in the water pipes (max. 0.5 bar). In order
to do this, remove the water pipe from the water pump and blow into the
water pipe in the direction of the appliances.
Empty the waste water tank. Take note of the environmental tips in this
chapter.
Empty the sewage tank. Take note of the environmental tips in this
chapter.
Clean the water tank and then rinse it out thoroughly.
Let the water system dry for as long as possible.
After emptying, leave all water taps on in the central position.
Leave the safety/drainage valve (Truma) and all drain cocks open.
10.3 Waste
water
tank
The waste water tank holds approx. 150 l.
Position and access, see section 10.6.
Hot air from the living area heater heats the waste water tank. This protects
the waste water tank from frost.
If the living area heater is out of order, the waste water tank no longer is
sufficiently protected against frost. If there is a risk of frost, empty the
waste water tank and leave the drain cock open.
Never pour boiling water directly into the sink outlet. Boiling water could
cause deformation and leaks in the waste water pipe system.
Only empty the waste water tank at disposal stations, camping sites or
caravan sites especially provided for this purpose.
