with a funnel or similar for filling.
 Set all the water taps to "Hot" and open them. The water pump is turned
on. The warm water pipes are filled with water.
 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 boiler is 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.

11.5 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 the 12 V power supply on the panel (Power Pack SE).
 Switch off the 240 V power supply on the 240 V automatic circuit breaker.
 Open all drain cocks.
 Take off the external water connection.
 Open all water taps and set to the central position.
 Hang the shower handset up in the shower position.
 Empty the waste water tank. Take note of the environmental tips in this
chapter.
 Empty Thetford cassette. 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 all drain cocks open.
 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.
 Take note of the environmental tip in this chapter.
