According to the applicable regula-

used on the drinking water supply
without a system separator. Use a
suitable system separator manufactured by

separator as per EN 12729 Type BA. Water
flowing through a system separator is consid-
ered non-drinkable.

high-pressure pump and accessories. For
protection, the use of the KÄRCHER water fil-
ter (optional accessory, order no. 4.730-059)
is recommended.

Push the water supply hose onto the cou-
pling unit, then connect it to the water sup-
