Monitoring and safety devices
Overflow valve with two pressure
switches (HDS-C 7/11, HDS-C 9/15
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.
Overflow valve with a pressure switch
(HDS-C 8/15-E)
If the hand-spray gun is closed such
–
that the whole water flows back to the
pump suck side, the pressure switch
shuts down the pump.
If the hand spray gun is opened again,
–
the pressure switch switches on the
pump again.

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 serv-
ice.
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-
ulary.
Motor protection switch
The motor protection switch interrupts
–
the electric circuit if the motor is over-
loaded.
Exhaust temperature limiter (HDS-C 7/
11, HDS-C 9/15
The temperature stop switches off the
–
machine when the waste gases have
reached very high temperatures.
Flame monitoring (HDS-C 7/11, HDS-C 9/
15)
If the burner does not ignite or the flame ex-
tinguishes during operation, then the flame
monitor switches off the fuel supply.
