Caution
Impurities in the water can damage the
high-pressure pump and the accessories.
For protection, the use of the KÄRCHER
water filter (optional accessory, order no.

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!
