Warning
Observe regulations of water supplier.
According to the applicable regula-
tions, 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 alternative, a system
separator as per EN 12729 Type BA. Water
flowing through a system separator is con-
sidered non-drinkable.
Caution
Always connect the system separator to
the water supply, never directly to the appli-
ance!
For connection values refer to technical
specifications
Connect the supply hose (minimum
length 7.5 m, minimum diameter 3/4“) to
the water connection point of the ma-
chine and at the water supply point (for
e.g. a tap).

The supply hose is not included.
Open the water supply.
Screw the suction hose with filter (order
no. 4.440-238.0) to the water connection.
