Safety Devices
Safety devices serve for the protection of the
user and must not be put out of operation or
bypassed with respect to their function.
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 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.
