Maintenance And Care - Kärcher BP 3 Home Mode D'emploi

Permanent installation
With a permanent installation the pump can be screwed
onto a suitable surface.
 Use suitable screws to screw the bases 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, 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 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.
Operation
BP 3 Home:
 Insert the mains plug into the socket.
 Switch the appliance on at the appliance switch.
BP 5 Home:
 Insert the mains plug into the socket.
Note
Pump starts running immediately. Wait till the pump
sucks in and pumps uniformly, then shut the gate valve
in the pressure pipe. The pressure switch deactivates
the motor when the shut-off pressure is reached. The
storage boiler is now full; the domestic water supply sys-
tem is ready for operation.
If there is a lack of supplied water, the switch-off pres-
sure is not reached; the pressure switch cannot shut off
the appliance. The water in the pump head will then
heat up.
In case of overheating, the power supply is interrupted
by a thermal switch, to avoid damage to the pump from
overheating.
The supply of power is switched back on after the appli-
ance has cooled off.
Note
The cooling down time until the motor starts up again
can be up to 150 min.
We recommend installing a dry run protection unit to
regulate the lack of water situation (see special acces-
sories).
CAUTION
System is under pressure!
(For pressure details see chapter on technical specifica-
tions)
Finish operation
BP 3 Home:
 Switch the appliance off at the power switch.
 Disconnect the main plug from the socket.
BP 5 Home:
 Disconnect the main plug from the socket.

Maintenance and Care

DANGER
Turn off the appliance and remove the mains plug prior
to any care and maintenance works.
Open the connected shutoff valves to relief pressure
and reclose them. The system is free of pressure.
 Rinse the pump after every use if you use to trans-
port water with additives.
Maintenance
 Check the pressure of the air filling in the storage
boiler every six months. If necessary, refill up to 2.0
bar in switched off / zero-pressure state (discon-
nect device, open the water cock).
Illustration
The air valve is located under the cover. Turn in anti-
clockwise direction to unscrew the cover.
CAUTION
In order to prevent accidents or injuries, keep in mind
the weight of the appliance during transport (see Spec-
ifications).
When transporting in vehicles
 Secure the appliance against shifting and tipping
over.
CAUTION
In order to prevent accidents or injuries, keep in mind
the weight of the appliance when selecting a storage lo-
cation for it (see Specifications).
Storing the Appliance
 Fully drain the appliance prior to storing it.
 Store the appliance in a frost free area.
