10.4.5 Hot water source
The hot water source can either be operated using the 240 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. 129). The indicator lamp (Fig. 129,1) 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.
Switching on:
Connect the vehicle to the external 240 V power supply and switch on the
240 V automatic circuit breaker.
Switch on the operating switch (Fig. 129). Indicator lamp (Fig. 129,1) on
the switch is illuminated.
The water in the hot water source is heated up to 65 °C.
Switching off:
Switch off the operating switch (Fig. 129). Indicator lamp (Fig. 129,1) on
the switch goes off.
Further information can be obtained in the manufacturer's instruction
manual.
Never use the hot water source without water inside it.
If the hot water source is not being used, empty it if there is any risk of frost.
Switch off the hot water source and empty it if the vehicle is not used.
If you want to empty the hot water source: Empty the water tank completely
before opening the drain cocks of the hot water source.
Do not fit a check valve in the cold water pipe between the hot water source
and the water pump.
Use a pressure reducer when connecting to a central water supply or with
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.
Dethleffs recommends that water from the hot water source is not used as
drinking water.
