Safety devices serve for the protection of
the user and must not be put out of opera-
tion or bypassed with respect to their func-
tion.
–
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 serv-
ice.
–
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.
–
The motor protection switch interrupts
the electric circuit if the motor is over-
loaded.
–
The temperature stop switches off the
machine when the waste gases have
reached very high temperatures.
