Fresh water system
5.15 Automatic waste water tank heating
The vehicle is equipped with waste water tank heating that switches on automatically when outside
temperatures drop below 4 °C. The waste water tank heating switches off automatically when the waste
water in the tank has reached a temperature of approx. 9 °C.
The waste water tank heating runs with 12 V power provided by the living room battery.
Do avoid a deep discharge of the living room battery, the 230 V power supply should always be connected
at temperatures below 5 °C.
If this is not possible, it must be ensured that the waste water tank is empty or does not exceed 9 litres,
as the automatic heating only works from a waste water tank fill of at least 10 litres.
CAUTION
Risk of frost damage!
● If there is a risk of frost, the waste water tank has to be fully drained.
