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.
11.6 Emptying the water system
To empty and ventilate the water system, proceed as follows. This prevents
frost damage and deposits:
Position the vehicle horizontally.
If necessary, switch off the water pump on the panel.
Switch off the 12 V power supply on the panel.
Shut off the boiler (see section 10.4).
Open drain cocks. To do so, set the rocking lever (Fig. 221,1) in a vertical
position.
Open the safety/drainage valve (only for Truma boiler). For this press the
pull switch down or turn the knob parallel to the safety/drainage valve.
For models with water drainage in the water tank:
Unscrew the cap of the water tank.
Open the water tank drain (see section 11.3.4).
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. 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.
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.
The Truma system (heater/boiler) has an electric safety/drainage valve
and, depending on the model, one or two drain cocks for emptying.
The Webasto system (heater/boiler) has an electric safety/drainage valve
and, depending on the model, one or two drain cocks for emptying.
Depending on the model, the Alde system (heater/boiler) has one or two
drain cocks for emptying.
