11.1 Water supply, general
An electric water pump pumps the water from the external water tank to the
individual water taps. Opening a water tap automatically switches on the water
pump and pumps water to the tap.
A canister or the waste water tank collects the waste water.
 Fill water tank from supply systems that have been verified to provide
drinking water quality.
 Only use such hoses or containers when filling that have been approved
for use with drinking water.
 Thoroughly rinse filling hose or container with drinking water before use
(2 to 3 times capacity).
 Empty filling hose or container completely after use and close openings
of the filling hose or container.
 Water left standing in the water tank or in the water pipes becomes
undrinkable after a short period. Therefore, before each use of the
vehicle, thoroughly clean the water pipes and the water tank. After each
use of the vehicle completely empty the water tank and the water pipes.
 In the case of lay-ups lasting more than a week disinfect the water
system before using the vehicle.
 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.
 The water pump will overheat without water and can get damaged. Never
operate water pump when the water tank is empty.
 Before using the water fittings, the 240 V power supply must be connected
and the 240 V automatic circuit breaker must be switched on, or the car-
avan must be electrically connected to the towing vehicle. Otherwise the
water pump will not work.
