DANGER
Danger of injury by electric shock.
The appliance may only be connected to al-
ternating current.
The highest allowed net impedance at the
electrical connection point (refer to techni-
cal data) is not to be exceeded. In case of
confusion regarding the power impedance
present on your connection, please contact
your utilities provider.
It is imperative to connect the appliance to
the electric mains by means of a plug. It is
forbidden to permanently connect the appli-
ance to the power supply. The plug serves
for the disconnection from the mains.
Use the extension cord that has an ade-
quate cross-section (see "Technical Data")
and unwind it fully from the cable drum.
For connection values, see type plate/tech-
nical data.
몇 WARNING
Observe regulations of water supplier.
According to applicable regula-
tions, the appliance must never be
used on the drinking water net
without a system separator. A suit-
able system separator by KÄRCHER or al-
ternatively a system separator according to
EN 12729 type BA must be used.
Water that was flowing through a system
separator is considered non-drinkable.
몇
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
