Heat distribution Depending on the model, the temperature of the convectors in the rear area
can be controlled separately. A stopcock is located in the rear of the vehicle
for this purpose.
The flow to the convectors in the rear area is controlled with the stopcock.
Opening the line to the
convectors:
 Set the lever (Fig. 198,1) of the stopcock parallel to the pipe (Fig. 198).
The wider the stopcock is opened, the higher is the heat output.
Closing the line to the
convectors:
 Set the lever (Fig. 199,1) of the stopcock at right angles to the pipe.
Setting the rotational
speed of the circulating
pump
The rotational speed of the circulating pump can be set with the control knob
(Fig. 200,2). At a lower rotary speed, the operating sounds of the pump are
quieter.
The control knob is located on the circulating pump (Fig. 200,1).
Setting the output:
 Turn the control knob (Fig. 200,2) in an anticlockwise direction. The output
is reduced.
 Rotate the control knob in a clockwise direction. The output is increased.

Z The hot-water heater is equipped with a very powerful pump. In smaller
vehicles, the pump can only be operated at full power if the pipes are bled.
Otherwise, this will increase wear; loud operating noises are the result.
