If water runs under the car even though everything is closed, it may be that a valve is still open:
- Make sure that the drain of the fresh water tank is closed.
- Make sure that the drain of the waste water tank is closed.
- Make sure that the valve for lowering the tank level to 20 litres is also closed. You will find it next to the lever of the fresh water tank:
- Make sure that the cold protection valve is not active. You can find it under the rear seat. On the side of the aisle you will find a small door:
The cold protection valve is inside it:
The cold protection (or anti freeze) valve automatically drains the boiler when there is a risk of frost. This prevents the drain from freezing.
The system measures the temperature inside the van. As soon as it is around 3 degrees or lower the system is activated and lets all the water that was in the boiler and the fresh water tank out. To deactivate the system, the room temperature has to be a least 7 degrees, otherwise the blue button will jump out again.
To ensure that the water supply continues to function and the valve is switched on, the blue lever must be turned clockwise and then the blue button must be pressed in.
