Water system
Never clean the tank with a dishwashing
brush and dishwashing detergent. This could
scratch the tank, providing bacteria and algae
with a much better foothold.
∆
Cleaning the water tank
After the water system has been used for a period, there
may be bacterial and algae growth in the tank. The tank
should therefore be cleaned at least a couple of times a
year. You should ideally clean the entire water system.
Never clean the tank with a dishwashing brush and
dishwashing detergent. This could scratch the tank, pro-
viding bacteria and algae with a much better foothold.
It is therefore better to clean the tank chemically, using
special chemicals intended for tank cleaning that can be
purchased from shops. These chemicals can be purchased
in liquid form or as tablets.
Mix with water and pump the mixture through the entire
water system, then allow it to stand for a while. Then rinse
through carefully with fresh water before filling the tank.
Remember to rinse out the water system
carefully with fresh water after cleaning,
before filling with water.
∆
The taps in the washroom and at the sink
should be left open. The drainage valve for
the water heater and the air screw for the water
heater should be left open. The drainage valve
for the water and drain tank must be closed.
∆
Remember that when the caravan is left unhea-
ted, or is left for any extended period, the water
and drainage systems must be emptied.
∆
Decalcification of the water system
Depending on the water lime content can it be strong depo-
sits in the tank, water hoses and the non return valve.
A decalcification of the water system should be made
at least once a year, or in connection with cleaning the
water system.
Mix for examplec citric acid or vinegar with water and
flush out the entire water system with the mixture and
let it stand for a while. Then rinse carefully with fresh
water before filling the tank on.
A decalcification of the water system should
be made at least once a year, to avoid depo-
sition in the tank, water hoses and the non
return valve. Remember to rinse out the water
system carefully with fresh water after decal-
cification, before filling the tank on.
