Permanent Installation - Kärcher BP 3 Home & Garden Originalbetriebsanleitung

With the ON/OFF switch the following three operating
conditions can be switched:
Switch position I/On
Continuous operation
Switch position 0/Off
Off
Switch position Auto
Automatic mode
System operation
In the automatic mode the house & garden pumps auto-
matically maintain the pressure in the system. If the
pressure falls below approx. 0.13 MPa (1.3 bar), the
pump is started. The pump is running as long as the flow
rate
> is approx. 60 l/h. If the withdrawal of water is complet-
ed, the pump goes into the stand-by mode after a short
stopping time. The system is now under pressure. In
case of water withdrawal and the resulting loss of pres-
sure the pump starts again.
The eco!logic models do not consume ener-
gy in the stand-by mode (input power = 0 W).

Preparing the Appliance
Illustration
 Screw the connection adapter in the suction con-
nection of the pump (inlet).
Tighten manually.
 Connect the vacuum-proof suction hose.
Note
In order to reduce the time required for suction to start
again, use a suction hose that is equipped with a back-
flow stop. This prevents the emptying of the suction
hose after use (see accessories).
Do not install the backflow stop directly on the pump
(suction or delivery side).
If sandy water is to be delivered, we strongly recom-
mend the use of an additional pre-filter (see optional ac-
cessories). Please install this filter on the suction side of
the pump, between the suction hose and the pump.
Please use original Kärcher suction pipes, filter compo-
nents and hose connections.

Operation
Settings
Description of the Appliance
When using components of other manufacturers, mal-
functions during drawing in the delivery fluid may arise,
especially when using bayonet connection systems.
Do not use quick couplings, but screwed connections
with domestic or permanent installations.
Illustration
 Screw the connection adapter in the delivery con-
nection of the pump (outlet).
Tighten manually.
 Connect delivery line.
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.
Illustration
 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.
Note
Even the smallest of leakage leads to malfunctioning.

Permanent installation

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 casing.
 Use suitable screws to screw it onto a level surface.
In case of a permanent installation the installation of a
flexible component such as a flexible pressure compen-
sating hose (see optional accessories) on the pressure
side is recommended. This has the following benefits:
 More flexibility during set-up and installation.
 Noise reduction, as no vibrations are transferred to
pipes in the domestic water system.
 In case of small leaks, the pump does not switch as
often.
Note
To facilitate subsequent emptying and pressure release
of the system, we recommend the installation of a stop-
cock between pump and pressure line.
(not included in delivery)
By closing the shut-off valve when emptying the pump you
can prevent water from escaping from the pressure line.
Install a pressure equalization container (see special
accessories) in case of increased pressure reductions
due to leakages in the domestic system (pump switches
on regularly without water removal).
 Insert the mains plug into the socket.
 Switch on the appliance using the ON/OFF switch.
 Optimum convenience with operation in the auto-
matic mode.
Illustration
 In order to reduce the suction time, lift the delivery
hose approx. 1m.
 Wait till the pump sucks in and transports water uni-
