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.

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.

Observe regulations of water supplier.

For connection values, see type plate/technical

data.

Î Use a fibre-reinforced water hose (not in-

cluded) with a standard coupling. (Minimum

ter connection on the appliance.

Î Push the water supply hose onto the cou-

pling unit, then connect it to the water supply.

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).

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 of the appliance.

Î Switch the appliance on "I/ON" and operate

until the water exits the high-pressure con-

nection without bubbles.

the tap is turned off as dry running will damage

the high-pressure pump.
