higher, however. If the temperature should
sink below 3°C, please follow the procedure
described with regard to the safety valve on
Page 6-5.
• Note
As the fall in pressure in the freshwater
system sets the freshwater pump into
circulation through the automatic emptying
of the boiler, the entire freshwater 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 7-2).
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 fridge 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 hand-
brake (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-Mobil motorhome is designed
for use winter as well. In order to avoid
disturbances to operation, however, you
should consider the following points:
• Fresh and sewage water equipment
These also remain functional at temperatures
below zero. However, the vehicle has to be
heated continuously using the body heater.
Addition of cooking salt over the sink drain
reduces the risk of the sewage water slider
of icing up.
• Butane does not turn into gas at temperatures
below 0°C. Propane is unproblematic 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
