Cleaners intended for
commercial use must be
equipped with a mains
power lead type H 07 RN-F
by a qualified electrician.
The mains power lead must
not differ from the version
specified by the manufactur-
er and may only be changed
by an electrician.
If your 3-phase cleaner was
supplied without a plug,
have it fitted with a suitable
3-phase plug with protecti-
ve conductor contact by an
electrician.
The mains power lead must
not differ from that
specified by the manufactur-
er.
We strongly recommend
that the power supply to the
high-pressure cleaner be
connected via a residual-
current circuit breaker which
interrupts the power supply
either if the leakage current
to earth exceeds 30 mA for
30 ms or which contains an
earth testing circuit.
If an extension lead is used,
please observe the mini-
mum cross-section of the
lead:
Lead length Cross-section

mm²
up to 20
1.5
20 to 50
2.5
If an extension lead is used,
all live parts (plug, cable,
plug socket) must be
located so that the protec-
tion class „watertight" is
ensured. This can also be
achieved by
protecting the lead.
CAUTION!
Unsuitable extension leads
can represent a source of
danger.
CAUTION!
Never spray electrical
equipment with water:
Danger for persons, danger
of short-circuit.
The cleaner may only be
connected to a correctly
installed plug socket.
TESTING
The cleaner conforms to the
„Guidelines for Liquid Spray
Jet Devices". The high-
pressure cleaner must be
subjected to a safety
examination in accordance
with the
„Accident Prevention
Regulations for Working
with Liquid Spray Jet
Devices" as required, but at
least every 12 months, by an
authorised inspector.
After all repairs or modifica-
tions to electrical equip-
ment, the protective
conductor
resistance, the insulation
resistance and the leakage
current must be measured.
Furthermore, a visual
inspection of the mains
power lead, a voltage and
current measurement and a
function test must be carried
out. Our after-sales service
technicians are at your
disposal as authorised
inspectors.
The complete „Accident
Prevention Regulations for
Working with Liquid Spray
Jet Devices" are available
from the Carl Heymanns
Verlag KG, Luxemburger
Strasse
449, 50939 Cologne or
from the appropriate
association of employers'
liability insurances.
SAFETY DEVICE
Unacceptably high pressure
is fed back without residual
pressure via a bypass line
into the intake line of the
pump when the safety
device is tripped. The safety
device is set and sealed at
the factory and must not be
adjusted.
