Water system
Water tank
The system comprises a water heater, a 20 or 40 litre
water tank with a submersible pump which is controlled
by valves with microswitches, as well as lines to the taps
in the kitchenette and washroom.
The water pump starts when the tap handle is twisted. The switch
for the water pump on the control panel must first be switched
on (see reference for ”Control panel 12 V” on page 32).
The water tank is located in a bed box on the left side at
the front or rear of the caravan, and fresh water is filled
through the external water filler with a lockable lid (see
picture ” Filling with fresh water” ).
The system has an external drainage valve. The valve is
located under the floor on the left side of the caravan at the
rear or on the left side at the front adjacent to the water tank.
Under the floor by the valve, there is a cone for draining the
water tank and a hose for bleeding it. The valve is open when
the handle is parallel with the caravan lengthways, and closed
when the handle is at right angles to the caravan.
At temperatures below -30°C there is a risk of the drainage
valve under the floor freezing. In order to thaw out the valve,
undo the valve handle and cover the end of the shaft with an
insulating material. The valve will then thaw out in a few hours.
Filling with fresh water
The fresh water tank is filled through the external water
filler with a lockable lid.
Before filling, close the drainage valve for the water tank,
all taps and the drainage valve for the water heater, and
that the bleed screw for the water heater is closed (see
pictures ”Emptying the fresh water” on page 52).
After filling with water, the system may need to be bled.
Open a water tap and leave it open until water runs out
of it.
Don’t forget to close the drainage valve for
the fresh water tank before filling.
Also check that all taps and the drainage valve
for the water heater are closed, and that the
bleed screw for the water heater is closed.
