10.2.5 Emptying the water system
To empty and ventilate the water system, proceed as follows. This prevents
frost damage and deposits:
„
Position the vehicle horizontally.
„
Switch off the 12 V power supply on the panel.
„
Switch off the 230 V power supply on the 230 V fuse box.
„
Switch off the boiler.
„
Open the safety/drainage valve (Fig. 73). To do this turn the knob
(Fig. 73,1) parallel to the safety/drainage valve.
„
Open all drain cocks (Fig. 74 or Fig. 75).
„
Unscrew the cap of the water tank.
„
Remove water pump and water hose from the water tank.
„
Open the water tank drain.
„
Open all water taps and set to the central position.
„
Hold the shower handset up.
Z
If the vehicle is not used for several days or if it is not heated when there is
a risk of frost, empty the entire water system. Make sure that the 12 V
power supply on the panel is switched off. Otherwise, the water pump will
overheat and may get damaged. Leave the water taps on in central posi-
tion. Leave the safety/drainage valve and all drain cocks open. Frost
damage to appliances, frost damage to the vehicle and deposits in water-
carrying components can be avoided in this way.
