Winter operation
Fresh and waste water equipment
These also remain functional at
temperatures below zero. However,
the vehicle and the waste water
tank must always be heated by
means of the body heating (600H)
or the heating cartridge (635
models).
Addition of cooking salt over the
sink drain reduces the risk of the
waste water slider of icing up.
Butane does not turn into gas at
temperatures below 0°C. Propane is
unproblematical in this respect.
The anti-freeze protective device of
the heating system empties the
boiler automatically at
temperatures of approx. 3°C in the
boiler area. If the vehicle is heated,
the temperature in the boiler area is
generally higher, however. If the
temperature should sink below 3°C,
please follow the procedure
described with regard to the safety
valve on Page 5-4.
Note
As the fall in pressure in the fresh
water system sets the fresh water
pump into circulation through the
automatic emptying of the boiler,
the entire fresh water supply can be
discharged via the boiler. This can
cause damage to the pump if it
runs dry. Therefore always set the
pump or main switch on the control
panel to "Off" when leaving the
vehicle (Page 6-1).
In winter check after every journey
that the automatic venting system
of the gas cylinder box is not
blocked by ice or snow.
Winter covers are available for the
vent openings of the refrigerator
with gas operation in winter as an
optional extra.
The covers may also remain in
place during operation in winter.
Sufficient ventilation
is particularly important in winter,
in order to eliminate the high
humidity which arises because of
cooking, damp clothes etc.
Humidity can also be reduced with
a commercial dehumidifier.
Free the roof hatch regularly of
snow in order to free penetration of
melting water through the vents.
Do not secure your vehicle with the
handbrake (danger of freezing).
Engage a gear and place wedges
under the wheels.
A winter partition is available to
separate the driver's cabin from the
rest of the vehicle.
Your Karmann mobile home can be
used in winter. In order to avoid
disturbances to operation, however,
you should consider the following
points:
