Green indicator lamp (Fig. 155,7) is on.
The circulation fan automatically switches on when the heater is activated.
Switching off:
Turn the rotary switch (Fig. 155,3) to " " (Fig. 155,4).
Close the gas isolator tap "Heater/boiler" and the regulator tap on the gas
bottle.
After switching off the heater, the circulation fan may still run for a moment to
use up the residual heat.
Summer operation It is not possible to heat the vehicle in "Summer" operating mode. In "Summer"
operating mode, only the water in the boiler is heated.
Variant: Heater with gas
and 240 V electrical
operation
The heater can be operated with different types of energy:
Gas operation (Fig. 156,3)
240 V electrical operation with the output levels 900 W (Fig. 156,2) or
1800 W (Fig. 156,1)
Gas and 240 V electrical operation (mixed operation) with the output levels
900 W (Fig. 156,4) or 1800 W (Fig. 156,5)
The combination gas operation and 240 V electrical operation reduces the
heating-up time (only possible when the heater on the operating unit (Fig. 155)
is set to winter operation).
When 240 V electrical operation is selected, the yellow indicator lamp illumi-
nates (Fig. 156,6).
240 V electrical operation is only possible when the vehicle is connected to
the 240 V power supply.
Select the output level for 240 V electrical operation so that it corresponds
to the fuse protection of the 240 V connection (900 W for 3.9 A fuse,
1800 W for 7.8 A fuse).
When the heater on the operating unit is set to summer operation and the
energy selector switch is set to mixed operation, the heater still runs only
in 240 V operation. The gas burner is not switched on.
