
Screw the connection adapter in the
suction connection of the pump (inlet).
Tighten manually.
 Connect the vacuum-proof suction
hose.
Note
In order to reduce the time required for suc-
tion to start again, use a suction hose that
is equipped with a backflow stop. This pre-
vents the emptying of the suction hose after
use (see accessories).
If sandy water is to be delivered, we strong-
ly recommend the use of an additional pre-
filter (see optional accessories). Please in-
stall this filter on the suction side of the
pump, between the suction hose and the
pump.
Please use original Kärcher suction pipes,
filter components and hose connections.
When using components of other manufac-
turers, malfunctions during drawing in the
delivery fluid may arise, especially when
using bayonet connection systems.
Illustration

Screw the connection adapter in the de-
livery connection of the pump (outlet).
Tighten manually.
 Connect delivery line.
A garden hose with a minimum length
of 5 m at a diameter of 3/4" or 15 m at a
diameter of 1/2" is recommended.
Illustration
The 2-way adapter allows the simultaneous
operation of two appliances (e.g. washing
machine or sprinkler). It can be mounted in
a way that either both outlets are used at
the side or one outlet at the side and one
outlet at the top. If only one outlet is used,
the outlet that is not required can be closed
by means of the accompanying closing
cap.


Unscrew the lid of the filler neck and fill
in water up to the brim.
 Manually screw the lid all the way to the
stop on the filler neck.
 Open existing shutoff valves in the
pressure pipe.
With a permanent installation the pump can
be screwed onto a suitable surface.
Illustration

Pull out and turn the rubber feet on both
sides of the casing.
 Reinsert the rubber feed into the cas-
ing.
 Use suitable screws to screw it onto a
level surface.
In case of a permanent installation the in-
stallation of a flexible component such as a
flexible pressure compensating hose (see
optional accessories) on the pressure side
is recommended. This has the following
benefits:

More flexibility during set-up and instal-
lation.
 Noise reduction, since no vibrations are
transferred to pipes.
 In case of small leaks, the pump does
not switch as often.
Note
To facilitate subsequent emptying and
pressure release of the system, we recom-
mend the installation of a stop-cock be-
tween pump and pressure line.
