Water Supply; High Pressure Operation - Kärcher K 5.55 M Operating Instructions Manual

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 system 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/tech-
nical data.
Observe regulations of water supplier.
Screw the water filter on the water con-
nection of the device.
Screw the delivered coupling part on
the water filter.

coupling unit, then connect it to the tap.
Note: Use a fibre-reinforced hose (not in-
cluded) with a standard coupling.
– Minimum diameter, 1/2 inches (13 mm).
– Minimum length 7.5 m
Caution
Never operate the high-pressure cleaner
when the tap is turned off as dry running will
damage the high pressure pump.
Drawing in water from open reservoirs
When fitted with the appropriate accesso-
ries, this high-pressure cleaner can draw in
surface water, e.g. from water butts or
ponds (max. suction height 0.5 m).
Screw the water filter on the water con-
nection of the device.
As the standard coupling system is not
suitable for use in suction mode, the
Kärcher suction hose with integrated fil-
ter should be used instead (special ac-
cessory, order no. 4.440-238) and
suspended inside the water butt.
Remove air from appliance before oper-
ation.
Switch on the appliance without con-
nection the high pressure hose and run
it until the water discharging from the
high pressure outlet is free of bubbles.
