machine room.
WARNING
Damage to hearing for maintenance per-
sonnel is possible. Always wear ear plugs
while working at a running high pressure
module or other machines in the machine
room.
Electrical dangers
DANGER
Risk of electric shock!
– Never touch electrical cables, plug con-
nections and terminal boxes with wet
hands.
– Electrical connecting leads or extension
cables must not be damaged through
being driven over, crushed, or pulled or
the like. Protect the power cord from
heat, oil, and sharp edges.
– With mobile cleaning devices (e.g. with
high-pressure cleaners) the water jet
must never be aimed at electrical appli-
ances or units.
– All current-conducting parts in the work-
ing area must be protected against jet
water.
– Plants must only be connected to prop-
er earthed power sources.
– All work on electrical parts of the plant
must be carried out only by a qualified
electrician.
Danger from substances that are
harmful to health
DANGER
Do not drink the water emitted from the high
pressure module! It is not of potable quality.
Should processed water be used to oper-
ate the high pressure module, then the stip-
ulations of the manufacturer of the water
treatment plant on germination inhibition
must be observed.
Danger from power failure
The controls of the subsequent vehicle
washing unit must be designed in such a
way that a restart after power failure is ex-
cluded.
Danger to the environment from waste
water
The locally valid regulations on waste water
disposal are to be observed.

Behaviour in emergency situations

Safety Devices

Safety valve
The safety valve protects the high pressure
system against excessive pressure.
The safety valve opens when the permissi-
ble operating pressure is exceeded; water
flows outside.
Pressure switch
The pressure switch switches off the ma-
chine when the working working pressure
is exceeded and turns it back on when the
pressure is reduced.
