– While reducing the water supply at the
pump head or with the Servopress - reg-
ulation the overflow valve opens and part
of the water flows back to the pump suck
side.
– If the hand-spray gun is closed, so that
the whole water flows back to the pump
suck side, the pressure switch at the
overflow valve shuts down the pump.
– If the hand spray gun is opened, the pres-
sure switch on the cylinder head turns the
pump back on.
The overflow valve is set by the manufac-
turer and sealed. Setting only by customer
service.
– The safety valve opens, when the over-
flow valve resp. the pressure switch is
broken.
The safety valve is set by the manufacturer
and sealed. Setting only by customer service.

the burner to be turned on when there is
water shortage.
– A sieve prevents the contamination of
the safeguard and must be cleaned reg-
ulary.

machine when the waste gases have
reached very high temperatures.
