Manual switching between processed/
fresh water for using fresh water in the
high-pressure cleaner (for e.g. for rinsing).
Notice
The equipment may only be installed by an
– mechanic of Kärcher
– or an from Kärcher authorized individual
The following requirements are necessary
in order to install the equipment:
– frost-free room with adequate ventila-
tion and exhausts
– Floor path for collecting sludge
– Strong wall for fastening the system
Unpack the equpiment and dispose of the
packing material properly.
The water installation depends on the spe-
cific conditions of the existing plant compo-
nents such as
– Type and model of high-pressure
cleaner or washing system
Note
The processed water outlet of the system is
directly connected to the water inlet of the
high-pressure cleaner. This can lead to
foam formation in the swimmer tank in
high-pressure cleaners with a swimmer
tank. In such a case, the high-pressure
cleaner must be switched to suction opera-
tioins (see separate operating instructions
of the high-pressure cleaner).
– Type and models of building-side com-
ponents (sludge collector, pump basin,
etc.)
– Nominal widtht, lengths and type of
channels
Hence, the water installation must be done
according to the specific local conditions.
The immersion pump specifications in the
building must meet the requirements out-
line in the "Technical Data / Immersion
Pump Requirements" section.
