9.4.3 Hot water source (partially special equipment)
The hot water source can either be operated using the 230 V power supply
(electrical mode of operation), with the hot air of the heater system or both
types of energy. The hot water source heats approx. 5 l water to a temperature
of approx. 65 °C.
The electrical mode of operation is activated using the operating switch
(Fig. 159). The indicator lamp (Fig. 159,1) on the switch must illuminate.
During hot air operation, the water in the hot water source is heated up by the
heater and the circulating air.
Depending on the model, the vehicle is fitted with one or two hot water source
drain cocks.

strong pumps. The hot water source is designed only for pressures of up
to 1.2 bar. In addition, insert a safety/drainage valve in to the cold water
pipe.
