While reducing the water supply at the
pump head or with the Servopress -
regulation 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
pressure 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 water shortage safeguard prevents
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.
