Combination drain valve
Fig. 101: Combination drain valve
Use of the knurled thumb screw (1) on top of the fresh water tank
to operate the combination drain valve. The knurled thumb screw
is used for the easy control of the freshwater tank filling level.
When using the knurled thumb screw, the filling level of the fresh
water tank can be individually adjusted by changing height of the
drain (2). When opening the combination drain valve, the filling
volume of the water tank is reduced. By using this procedure, the
payload of the motor home can be increased, e.g., taking
additional luggage on your journey.
When arriving at the destination, the knurled thumb screw can be
closed again to utilise the entire tank volume and to fill with fresh
water.
To open the combination drain valve, turn the knurled thumb
screw (1) anticlockwise.
NOTE
To allow the tank and the lines to be completely
emptied, the mixing valves in the kitchen and
bathroom must also be opened and turned to the
middle position.
To close the combination drain valve, turn the knurled thumb
screw (1) clockwise.
