OPERATING INSTRUCTIONS
11-2
Check the state of the battery regularly
(must not be below 10 volts).
Close the main shutoff valve on the gas
cylinder and the shutoff valves on all the
other equipment.
Slightly open the refrigerator door.
Fill the fuel tank completely with fuel.
Charge the body battery and disconnect
the terminals, as low consumers, such as
the solenoid valve of the fresh water
pipelines or continuous stand-by function
of the radio (special equipment), can
cause the battery to discharge.
Empty the fresh water tank and fresh
water pipes. (In order to ensure that
emptying is complete, the vehicle must
stand completely horizontal).
• Empty the fresh water tank as described
on page 7-2.
• Open all the taps to the central position
between "Hot and "Cold" and pump out
the water remaining in the pipework sys
tem. Isolate the pipework system from
the pump at the inlet and outlet connec
tion (inlet-connection: two-wing screw
connector piece/outlet connection:
stainless steel collar band).
Remove the filter.
Note
Lay a cloth under the pump area.
• Do not reconnect the pipelines to the
pump.
• In order to avoid damage, all taps should
remain open.
Empty waste water tank.
Empty sewage tank.
Empty heating/hot water heater by
opening the hot water taps in the kitchen
and bathroom. The switch at the frost
valve of the boiler is set to "0", i.e. the
valve is open. This ensures emptying of
the boiler.
If the body battery is not disconnected,
because the vehicle should only be
immobilised for a short time, it is
absolutely advisable to empty the boiler
with the front protection valve in the
winter, in order to avoid uncontrolled
draining of the system during frosty
periods.
