Water supply
According to the applicable regula-
tions, the appliance must never be
used on the drinking water supply with-
out a system separator. Use a suitable
system separator manufactured by KÄRCHER;
or, as an alternative, a system separator as per
EN 12729 Type BA. Water flowing through a sys-
tem separator is considered non-drinkable.
Caution
Always connect the system separator to the wa-
ter supply, never directly to the appliance!
Note: Impurities in the water can damage the
high-pressure pump and accessories. For pro-
tection, the use of the KÄRCHER water filter (op-
tional accessory, order no. 4.730-059) is
recommended.
Water supply from mains
Observe regulations of water supplier.
For connection values, see type plate/technical
data.
Use a fibre-reinforced water hose (not includ-
ed) with a standard coupling. (Minimum diam-
eter 1/2 inch (13 mm), minimum length 7.5 m).
Screw the coupling element (supplied) to the
water connection on the appliance.
Push the water supply hose onto the cou-
pling unit, then connect it to the water supply.

Caution
Dry runs lasting longer than two minutes lead to

ance does not build up pressure within two min-
utes, switch it off and proceed as instructed in
