Safety Devices

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.
Water shortage safeguard
The safety mechanism against lack of wa-
ter prevents the heater from over-heating
when there is no water. The burner oper-
ates only when there is adequate water
supply.
Overflow valve
– If the hand spray gun is closed, the
overflow valve opens and the high pres-
sure pump diverts the water back to the
pump suction side. Thus the permissi-
ble working pressure is not exceeded.
– The overflow valve is set by the manu-
facturer and sealed. Setting only by
customer service.

Safety valve

– The safety valve opens when the over-
flow valve is defective.
– The safety valve is set by the manufac-
turer and sealed. Setting only by cus-
tomer service.
Pressure switch
The pressure switch switches off the burner
when the working pressure falls below the
minimum value and switches it on again
when it is exceeded.
The safety catch on the trigger gun pre-
vents the appliance from being switched on
unintentionally.
