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.
