Water supply
According to the applicable regula-
tions, the appliance must never be
used on the drinking water net
without a system separator. Use a
suitable system separator manufactured by
Kärcher; or, as an alternative, a system
separator as per EN 12729 Type BA.
Note: Impurities in the water can damage
the high-pressure pump and the accesso-
ries. For protection, the use of the Kärcher
water filter (optional accessory, order no.
4.730-059) is recommended.
Water supply from mains
Observe regulations of water supplier.
For connection values, see type plate/tech-
nical data.
Î Use a fibre-reinforced water hose (not
included) with a standard coupling.
(Minimum diameter 1/2 inch (13 mm),
minimum length 7.5 m).
Î Screw the coupling unit (supplied) to
the water connection on the appliance.
Î Push the water supply hose onto the
coupling unit, then connect it to the wa-
ter supply.
Drawing in water from open reservoirs
This high-pressure cleaner is suited to work
with the Kärcher suction hose with backflow
valve (Optional accessory, order no. 4.440-

ter butts or ponds (see specifications for
max. suction height).
Î Fill the Kärcher suction hose with back-
flow valve with water, screw to water
supply and hang into he water butt.
Î Separate the high pressure hose from
the high pressure connection point of
the appliance.

erate until the water exits the high-pres-
sure connection without bubbles.
