Water Supply; Working With Detergent - Kärcher K 2.20 M Manual Del Usuario

Water supply

According to the applicable regula-
tions, the appliance must never be
used on the drinking water supply with-
out 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 sys-
tem separator is considered non-drinkable.
Caution
Always connect the system separator to the wa-
ter supply, never directly to the appliance!
Note: Impurities in the water can damage the
high-pressure pump and accessories. For pro-
tection, the use of the KÄRCHER water filter (op-
tional accessory, order no. 4.730-059) is
recommended.
