Water supply
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 diame-
ter, 1/2 inches (13 mm). - Minimum length,
7.5 m.
"
Screw the coupling unit (supplied) to the water
connection on the appliance.
"
Push the water supply hose onto the coupling
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).
Drawing in water from open reservoirs
When fitted with the appropriate accessories, this
high-pressure cleaner can draw in surface water,
e.g. from water butts or ponds (max. suction
height 0.5 m).
"
Use the Kärcher water filter to protect the HP
pump and accessories (special accessories,
order no. 4.730-059). This filter removes dirt
from incoming water.
"
As the standard coupling system is not suita-
ble for use in suction mode, the Kärcher suc-
tion hose with integrated filter should be used
instead (special accessory, order no. 4.440-
238) and suspended inside the water butt.
