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 manufacturer 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 service.
Water shortage safeguard
– The lack of water fuse prevents the
heater from being switched on when
there is a water shortage.
– The lack of water fuse switches the
pump off after 2 minutes in case of a
water shortage to prevent dry runs.
Temperature controller
– The temperature limiter switches off the
heater when the temperature becomes
too high.
