• 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.
• Use motor start/delayed fuses with characteristic C or
D according to IEC/EN 60898-1 / IEC 947-2 or corre-
sponding standards outside IEC.
• 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.
• Nilfisk 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 Nilfisk distributor or similar qualified
person in order to avoid a hazard.
• Connecting the high pressure washer to a supply
system, the max allowed impedance is = 0,4023 Ω
(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 backflow preventer has been installed, Type BA
according to EN 60335-2-79.
• The backflow preventer can be ordered under number
106411177.
• As soon as drinking water has flown through the back-
flow preventer, it is no longer regarded as drinking
water.
• Operation by suction (e.g. a rainwater vessel) is car-
ried out without a backflow 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.
