water net without a system separator. A
suitable system separator by KÄRCHER or
alternatively a system separator according
to EN 12729 type BA must be used.
Water that has flown through a system sep-
arator is no longer classified as drinking
water.
Caution
Always connect the system separator to
the water supply, never directly to the appli-
ance!

tions for max. suction height).

Fill the suction hose with water.
 Screw the suction hose into the water
connection of the appliance and insert it
into the water source (e.g. rainwater
drum).
