– While reducing the water supply/quanti-
ty regulation at the hand spray gun, 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 is defective.
The safety valve is set by the manufacturer
and sealed. Setting only by customer ser-
vice.
– 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-
ular.
