Water supply

Warning
According to the applicable
regulations, the appliance
must never be used on the
drinking water supply without a
system separator. Use a suitable
system separator manufactured
by KÄRCHER; or, as an alterna-
tive, a system separator as per
EN 12729 Type BA.
Water flowing through a system
separator is considered non-
drinkable.
Caution
Always connect the system sep-
arator to the water supply, never
directly to the appliance!
Note: Impurities in the water can dam-
age the high-pressure pump and ac-
cessories. For protection, the use of
the KÄRCHER water filter (optional ac-
cessory, order no. 4.730-059) is rec-
ommended.
Water supply from mains
Observe regulations of water supplier.
For connection values, see type plate/
technical data.


(not included) with a standard cou-
pling. (Minimum diameter 1/2 inch
(13 mm), minimum length 7.5 m).

Drawing in water from open
reservoirs
This high-pressure cleaner is suited to
work with the KÄRCHER suction hose
with backflow valve (Optional accesso-
ry, order no. 4.440-238) to draw in sur-
face water, e.g. from water butts or
ponds (see specifications for max. suc-
tion height).
Fill the KÄRCHER suction hose

with backflow valve with water,
screw to water supply and hang into
the water butt.
Appliance ventilation: Switch the

appliance on with the high-pressure
hose detached and operate (max. 2
minutes) until the water exits the
high-pressure connection without
bubbles. Switch off appliance and
reconnect high-pressure hose.
Caution
Dry runs lasting longer than two
minutes lead to damages to the
high pressure pump. If the appli-
ance does not build up pressure
within two minutes, switch it off
and proceed as instructed in the
Chapter "Troubleshooting".
