Safety/drainage valve The boiler is equipped with a safety/drainage valve (Fig. 65). The safety/drai-
nage valve prevents water in the boiler from freezing, when there is frost and
the heater is not switched on. The safety/drain valve is installed near the
heater or in the floor storage compartments under the table.
Winter operation In the "Heater and boiler" switch setting in winter operation, the boiler is
already switched on.
Summer operation In summer operation the water can be heated to 40 °C or 60 °C.
Switching on:
Open the regulator tap on the gas bottle and the gas isolator tap "Heater/
Boiler".
Set the rotary switch (Fig. 64,2) on the operating unit (Fig. 64) to "Summer
operation" (Fig. 64,1).
The yellow indicator lamp (Fig. 64,4) lights up during the heating up period.
When the set water temperature is reached, the period of heating up is fini-
shed and the yellow indicator lamp fades.
Switching off:
Set the rotary switch (Fig. 64,2) on the operating unit (Fig. 64) to " ".
Close the gas isolator tap "Heater/Boiler" and the main regulator tap on the

When the vehicle is not used for a long period of time, open the safety/drai-
nage valve and drain the boiler.
At temperatures below approx. 3 °C the safety/drainage valve opens auto-
matically. Before filling the boiler switch on the heater and wait until the
temperature of the safety/drainage valve exceeds 7 °C. Only then can the
safety/drainage valve be closed again.
The water pump and the water fittings are not protected against freezing by
the safety/drainage valve.
The drainage neck of the safety/drainage valve has to be free of dirt (e.g.
leaves, ice) at all times.
