Water supply
According to the applicable regula-
tions, the appliance must never be
used on the drinking water net with-
out a system separator. Use a suita-
ble system separator manufactured by
Kärcher; or, as an alternative, a system sepa-
rator as per EN 12729 Type BA.
Note: Impurities in the water can damage the
high-pressure pump and the accessories. 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/techni-
cal data.
Use a fibre-reinforced water hose (not in-
cluded) with a standard coupling. (Mini-
mum diameter 1/2 inch (13 mm),
minimum length 7.5 m).
Illustration
Screw the coupling unit (supplied) to the
water connection on the appliance.
Push the water supply hose onto the cou-
pling unit, then connect it to the water sup-
ply.
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-
238) to draw in surface water, e.g. from water
butts or ponds (see specifications for max.
suction height).
Fill the Kärcher suction hose with back-
flow valve with water, screw to water sup-
ply and hang into he water butt.
Separate the high pressure hose from the
high pressure connection point of the ap-
pliance.
Switch the appliance on "I/ON" and oper-
ate until the water exits the high-pressure
connection without bubbles.
Turn off the appliance "0/OFF".
