Saving energy in winter
It is very easy to save energy inside your caravan. This applies es-
pecially to heating in winter.
The following applies for saving energy:
• Meter the exact use of ventilation in the vehicle and the heating
valve.
• Open the door as little and as briey as possible.
• If you are camping in winter, attach an outer tent as protection
against the cold.
At the end of the winter season
The following applies for the care of the vehicle:
• Clean the exterior and use normal car wax to preserve metal parts.
• Do not forget to remove ue extensions, cover panels on refrige-
rators, etc.
The following applies for containers:
• If the interior is suciently heated, the fresh water tank, water
pipes and therme/Combi heating system/boiler* should not
freeze. Fill all of the water containers only after the interior has
been thoroughly heated.
• Since waste water is collected outside the vehicle, add antif-
reezer or common salt to it. The drain cock of the sewage pipe
must be kept clear.
• The toilet can be used normally, even in cold weather, as long
as the interior of the caravan is heated. If there is a danger of
frost, both the excrement and the ushing water tanks (model-
specic) should be emptied.
Continue to heat the vehicle while you are sleeping!
The following applies for heating:
• Both the air intake as well as the exhaust gas openings of the
heating system must be kept free of snow and ice (if necessary,
use ue extensions).
• It takes longer to heat up the caravan in winter, especially to
heat hot water.
• Do not let the interior cool down completely when you are away
or at night; set the heating to low and leave it on.
• The caravan uses considerably more gas in winter than in sum-
mer. Two 11 kg bottles of gas will be used up in just under one
week.
• Therefore, should you stay longer in one place, it is worthwhile
to set up an outer tent. It will help to acclimatise the caravan
and keep the dirt out.
