Emptying the water system
To empty and ventilate the water system, proceed as follows. This will avoid
frost damage:
Position the vehicle horizontally.
Switch off water pump on panel.
Switch off the 12 V power supply on the panel.
Shut off the boiler (see section 9.4).
Open all drain cocks. To do this, position the drain cock's rocking lever
(Fig. 237,1) vertically or turn the drain cock's cap (Fig. 238,1) in an anti-
clockwise direction.
Open the safety/drainage valve (Truma). To do this turn the knob parallel
to the safety/drainage valve. The push button jumps out.
Open the water tank drain.
Open all water taps and set to the central position.
Hang the shower handset up in the shower position.
Hold the water pump up until the water pipes are completely empty.
Check whether the water tank is completely empty.
Blow out the remaining water in the water pipes (max. 0.5 bar). To do this,
remove the pipe from the water pump and blow into the pipe.
Empty the waste water tank. Take note of the environmental tips in this
chapter.
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 certain that the water
pump is switched off on the panel. Otherwise, the water pump will overheat
and may get damaged. Leave the water taps on in central position. Leave
the safety/drainage valve (if there is one) 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.
Z
If the water pump can be turned off from the panel, always turn off the water
pump from the panel before you empty the water system. Otherwise the
water pump runs until it overheats or the battery is empty.
Z
The Truma system (heater/boiler) has a safety/drainage valve and,
depending on the model, one or two drain cocks for emptying.
Z
Depending on the model, the Alde system (heater/boiler) has one or two
drain cocks for emptying.
