or bent even if there is no externally vis-
ible damage.
– Store the high-pressure hoses in such a
way that they are not subject to any me-
chanical load.
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.
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.
– 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.
– 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.
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.
