Water Supply - Kärcher K 5.91 M Originalbetriebsanleitung

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.
Use a fibre-reinforced hose (not includ-
ed) with a standard coupling:
- Minimum diameter, 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
- order No. 4.730-059).
Water supply 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).
Use the Kärcher water filter to protect
the HP pump and accessories (special
accessories). This filter removes dirt
from incoming water.
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) and suspended inside the
water butt.
Remove air from appliance before oper-
ation: Switch on the appliance when the
HP hose is not connected and run it until
14
English
the water which discharges from the HP
outlet is free of bubbles. Switch off ap-
pliance and connect HP hose.
Note: Fill suction hose with water before
use, this will help ventilate the pump of air.
Start up

ance.

High pressure operation
Risk of injury
The trigger gun is subjected to a recoil force
when the water jet is discharged. Make

Carrying out the most common cleaning
tasks. The work pressure can be stageless-
ly regulated between "Min" and "Max".

sition.

pliance is being operated in low pressure
mode.

tion (Vario Power).
