Water supply
According to the applicable regula-
tions, the appliance must never be
used on the drinking water net without
a system separator. Use a suitable sys-
tem separator manufactured by Kärcher; or, as
an alternative, a system separator as per EN
12729 Type BA.
Water supply from mains
For connection values, see type plate/technical
data.
Observe regulations of water supplier.
Use a fibre-reinforced hose (not included)
with a standard coupling:
- Minimum diameter, 1/2 inches (13 mm).
- Minimum length, 7.5 m.
Screw the coupling unit (supplied) to the wa-
ter connection on the appliance.
Push the water supply hose onto the cou-
pling unit, then connect it to the tap.
Caution
Never operate the high-pressure cleaner when
the tap is turned off as dry running will damage
the HP pump.
If the water supply is not clean, the Kärcher water
filter must be used (special accessory - order No.
4.730-059).
