KARCHER BP 3 Home Booster Pump Instruction Manual

KARCHER BP 3 Home Booster Pump

Product Information

The BP 3 Home and BP 5 Home are domestic water pumps designed for use in private households. They are not intended for commercial use and are only to be used indoors. The pump is not suited for increasing the existing line pressure.

The product is meant for use as a house water tank. It can be used with different types of water such as used water, well water, water source, rainwater and water from swimming pool (provided the dosing of additives is proper).

Product Usage Instructions

Vorbereiten
To prepare the pump for operation, remove the closure plug and connect the adapter to the suction connection of the pump.

Festinstallation
For permanent installation, secure the pump to a flat surface using screws and mount it in an upright position.

Betrieb
Before operating the pump, ensure that the system is under pressure (refer to technical specifications). To start the pump, turn on the power supply. To stop the pump, turn off the power supply.

Pflege, Wartung
Clean the pump regularly to ensure its proper functioning. Unscrew the cover in an anti-clockwise direction to access the air valve. The membrane in the pressure vessel may need to be replaced if it is defective. Refer to the maintenance section for more details.

Transport
When transporting the pump in a vehicle, ensure that it is secured properly to prevent damage. For storage, keep the pump in a dry and cool place.

Troubleshooting

If the pump does not function properly, refer to the ‘Vorbereiten’ and ‘Wartung’ sections for possible solutions. If the problem persists, contact a qualified technician.

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 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 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 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 (disconnect device, open the water cock).

Illustration C
The air valve is located under the cover. Turn in anti-clockwise 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 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.

Troubleshooting guide

DANGER
To 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 running Note

The 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 de- pends on the transport height and the connected periphery| Keep max. flow height, see technical data. If nec- essary, 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.

Our Kärcher branch will be pleased to help you further in the case of questions or faults. See address on the reverse.

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
