• It is recommended that the electrical supply to the
machine should include a residual current device that
will interrupt the supply if the leakage current to earth
exceeds 30 mA for 30 ms.
• Due to the high power consumption of the machine an
appropriate mains fuse is required.
• Inadequate extension cables can be dangerous. If an
extension cable is used, it shall be suitable for outdoor
use, and the connection has to be kept dry and off the
ground.
• BERNER recommends use of an extension cable
drum when cable extension is needed which keeps
the socket at least 60 mm above the ground.
• If the electric cable is damaged, it must be replaced
by an authorized BERNER distributor or similar quali-
fi ed person in order to avoid a hazard.
• Connecting the high pressure washer to a supply
system, the max allowed impedance is = 0,4023

(Zmax). Consult with the supply authority that the
equipment is connected only to a supply of that im-
pedance or less.
Water connection
• This high pressure washer is only allowed to be con-
nected with the drinking water mains, when an appro-
priate backfl ow preventer has been installed, Type BA
according to EN 60335-2-79.
• The backfl ow preventer can be ordered under number
106411177.
• As soon as drinking water has fl own through the back-
fl ow preventer, it is no longer regarded as drinking
water.
• Operation by suction (e.g. a rainwater vessel) is car-
ried out without a backfl ow preventer – see “ Connec-
ting to a pressureless water supply ”. The machine
can be connected to water mains with a max. inlet-
pressure of 1 MPa/10 bars and max. 60°C.
