Frequently Asked Questions - BP 3 Home Kärcher

How to prime the BP 3 Home pump?

Unscrew the cover of the filling tube (filling neck) and fill with water until overflow, then close tightly. Open the shut-off valves on the pressure side before connecting the pump.

Why does the pump run but not deliver water?

This may be due to air in the pump (re-prime) or a closed valve on the pressure side. Also check the water level in the source.

What to do if the pump does not start or stops suddenly?

Check power supply (fuses, plug). If the thermal circuit breaker has tripped (overheating), unplug and let it cool for up to 150 minutes before restarting.

How to adjust the service pressure?

The service pressure is preset between 1.7 and 2.8 bar (depending on the model). Adjust the air pressure in the pressure tank to 2.0 bar (when empty) via the pneumatic valve under the cap.

What regular maintenance is required?

Every six months, check the air pressure of the pressure tank (2.0 bar when empty). After use with additives (pool), rinse with clear water. Before storage, drain completely.

How to store the pump in winter?

Drain all water from the pump (open the drain plug). Store in a frost-free location to avoid damage.

Why does the pump make a vibrating noise?

This may be due to the diaphragm of the pressure tank. Try reducing the air pressure in the tank to 2.0 bar to dampen the noise.

How to bleed the air from the system?

Open a tap on the pressure side and let the pump run until water flows without bubbles. Ensure the suction hose is properly submerged.

Is the check valve not closing properly?

Check the check valve on the pressure side: it must be clean and in good condition. A defect can cause pressure loss and frequent restarts.

What is the warranty and how to repair the unit?

The warranty covers material or manufacturing defects. For any repair or claim, contact the dealer or an authorized Karcher service center with proof of purchase.

Preparing the Appliance

→ Check max. air pressure in the storage tank prior to commissioning. If necessary, refill up to 2.0 bar with a commercially available air pump with the system switched off / zero-pressure state.
→ Secure device against slipping off (fix it with screws, if needed).
→ Remove the plug.
→ Screw the connection adapter in the suction connection of the pump (inlet). Tighten manually.
→ Screw check valve onto connector adapter at the suction connection. Tighten manually.
→ Connect the vacuum-proof suction hose with integrated backflow stop on the suction side. (available as optional accessory)
→ Screw the connection adapter in the delivery connection of the pump (outlet). Tighten manually.
→ Connect delivery line.

Illustration B

→ Unscrew the lid of the filling nozzle and fill in water till it overflows.
→ Screw on the lid on the filling nozzle.
→ Open existing shutoff valves in the pressure pipe.

Note

Even the smallest of leakage leads to malfunctioning.

→ In case of leaks, seal all connections with a suitable sealant (e.g. Teflon tape) to prevent malfunction due to leakage or air intake.

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 compensating 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 stopcock 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.
→ Insert the mains plug into the socket.

BP 5 Home:

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 system is ready for operation.

If there is a lack of supplied water, the switch-off pressure 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 appliance 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 accessories).

CAUTION

System is under pressure!

(For pressure details see chapter on technical specifications)

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.

Care

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 transport 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 (disconnect device, open the water cock).

Illustration C

The air valve is located under the cover. Turn in anticlockwise direction to unscrew the cover.

Transport

△CAUTION

In order to prevent accidents or injuries, keep in mind the weight of the appliance during transport (see Specifications).

When transporting in vehicles

→ Secure the appliance against shifting and tipping over.

Storage

△CAUTION

In order to prevent accidents or injuries, keep in mind the weight of the appliance when selecting a storage location for it (see Specifications).

Storing the Appliance

→ Fully drain the appliance prior to storing it.
→ Store the appliance in a frost free area.

Troubleshooting

△DANGERTo avoid risks, all repairs and replacement of spare parts may only be carried out by authorized customer service personnel.First pull out the plug from the mains before carrying out any tasks on the machine.
Fault Cause Remedy
Pump runs but does not transport	Air in the pump see chapter “Preparing the appliance”
	Air does not come out on the pressure side	Open tap on pressure side
	No water available. Check the water reservoir.
Pump does not run or suddenly comes to a standstill during operations	Power supply interrupted Check fuses and electrical connections
	Thermal protection switch in the motor has switched off the pump as it was over-heated.	Pull out the mains plug, let the pump cool down, clean the suction area, prevent dry runningNoteThe cooling down time until the motor starts up again can be up to 150 min.
Pump switches itself off and back on	Thermal protection fuse has switched the pump off to protect from overheating or turned it back on after it has cooled off.	In order to prevent a repetition, the system should be checked for leaks and sealed.
Motor starts up immediately after switch off	Pressure is not retained in the system Check connections including sealings and control the water outlet.The smallest of leakages can affect the operation adversely.
	Air pressure in the storage boiler is too low.	Fill storage boiler with 2.0 bar. See chapter “Maintenance”
	Backflow valve does not close properly Check backflow valve on suction side.
	Membrane in pressure tank is defective Replace membrane
Pump transports is reducing or transported quantity is too low	Suction filter or check valve (special accessories) contaminated	Clean suction filter or check valve (special accessories)
	The quantity transported by the pump depends on the transport height and the connected periphery	Keep max. flow height, see technical data. If necessary, select a different hose diameter or hose length.
Vibrating sound while taking out water	Membrane in pressure tank vibrates	Noise caused by operations and the noise can be reduced by reducing the pressure in the air filling of the storage tank.

Subject to technical modifications!

Operating pressure and transported quantity depends on the suction height and the connected periphery!

The possible delivery rate is even larger:

• the lower the suction and flow heights
• the larger the diameter of the hoses used,
• the shorter the hoses used are
• the lower the pressure loss caused by the connected accessories
