Some models have the ability
to be used on either 230 Volt
or a 440 Volt power supply. On
these models confirm that the
voltage selector switch is in the
proper position to match the
power supply. Otherwise dam-
age to machines electrical com-
ponents may occur.
The following should be
observed when connecting the
high pressure washer to the
electric installation:
•
Only connect the machine
to an installation with earth
connection.
•
The electric installation
shall be made by a certified
electrician.
•
According to IEC 60364-1
it is strongly recommended
that the electric supply to
this machine should include
a residual current device
(GFCI).
3.13 Electrical
connection
This high pressure washer/cleaner is only allowed to be connected
with the drinking watermains, when an appropriate backflow pre-
venter has been installed, Type BA according to EN 1717. If the
backflow preventer hasn’t been supplied, one can be ordered from
your dealer. As soon as water has flown through the BA valve, this
water is not considered to be drinking water any more. The length
of the hose between the backflow preventer and the high pressure
washer must be at least 12 metres (min diameter 3/4 inch) to ab-
sorb possible pressure peaks.
In the case of poor water quality (sand, etc.) add a water filter to
the machine.
Rinse the water supply hose briefly in order to prevent sand and
other dirt particles entering into the machine.
Operation by suction (for example from a rainwater vessel) is car-
ried out without backflow preventer. Contact your dealer for suction
set recommendations.

Cable connections should be
kept dry and off the ground.
Cables on drums should always be completely unwinded to
prevent the cable from overheating. Extension cables should be
of a watertight construction and comply with the below-mentioned
requirements for length and cable dimensions.
