Overflow valve with two pressure
switches
– 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.
Safety valve
– 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 ser-
vice.
Water shortage safeguard
– 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.
Temperature stop for exhaust gases
– The temperature stop switches off the
machine when the waste gases have
reached very high temperatures.
