Draining the water and waste water system
When the vehicle is placed out of service for an extended period of time or is not heated when
there is a risk of frost, empty and clean the entire water system and allow to dry. Leave the
water taps and drain cocks as well as all drain valves open.
Draining the water supply:
Switch the water pump and the boiler off or disconnect electrical plug connection.
Open all water taps to the centre position.
Empty the water tank (Chapter 12.1.1)
Open the boiler safety valve (Chapter 13.1.7).
The tank must be rinsed, cleaned and allowed to dry.
On vehicles with pressure pump, switch the pump on for a short time to remove residual
water.
Leave all water taps open in the centre position until the vehicle is placed into service
again. The water pump may be switched on only when water has been filled.
Emptying the waste water system:
Allow the waste water to flow into the waste water tank.
Drain the waste water tank at the intended waste water disposal station.
Leave the drain cocks as well as all drain valves open.
Warning!
Health hazard
Prevent the formation of bacteria and algae in the water tank.
Change the water at regular intervals including the boiler contents (e.g. twice a
week).
After the end of every journey, the water tank including the boiler must be drained,
cleaned thoroughly and left open (venting).
Thoroughly clean the hoses after the end of each journey.
Use disinfectant for the water tank.
Caution!
Damage due to frost
Prevent frost damage to the water system.
If the vehicle is not heated when there is a risk of frost (winter), damage to the compo-
nents of the water or waste water system can occur due to the formation of ice. Drain
all water-conducting components.
