If the hand spray gun is closed, the
overflow valve opens and the high pres-
sure pump diverts the water back to the
pump suction side. Thus the permissi-
ble working pressure is not exceeded.

facturer and sealed. Setting only by
customer service.

The safety valve opens when the over-
flow valve is defective.

The safety valve is set by the manufac-
turer and sealed. Setting only by cus-
tomer service.
The pressure switch switches off the burner
when the working pressure falls below the
minimum value and switches it on again
when it is exceeded.
