Safety instructions

⚠️ Danger of death

Violating these safety instructions may result in death through electrocution.

■ Check the power cord with mains plug for damage before every use. If the power cord is damaged, please arrange immediately for the exchange by an authorized customer service or a skilled electrician.
■ All electrical sockets should be fixed in an area that is protected against floods.
■ To separate the machine from the mains, pull the plug and not the power cord.
■ Do not scrape the power cord across sharp edges and ensure that it does not get pressed.
■ Install the appliance in a safe position at a place protected against flooding.
■ The voltage indicated on the type plate must correspond to the voltage of the electrical source.
■ To avoid risks, all repairs and replacement of spare parts may only be carried out by the authorised customer service personnel.
■ The pump does not switch off if there is no water supply. The water in the pump gets heated and can cause injury when it comes out!
The pump may be operated for maximum 3 minutes in this operating status.
Tip: Dry run protection ((6.997-355.0), swimmer switch (6.997-356.0) are available as options!
■ Do not use this pump as an immersion pump.
■ When using the pump near to pools, garden ponds or fountains, observe a minimum distance of 2m and safeguard the device against slipping into the water.
■ Follow the rules for electrical safety of equipment:

Only operate pumps near to pools, garden ponds or fountains, if they are equipped with an earth leakage circuit breaker with a nominal error current of max. 30 mA. It is not permitted to activate the pump, if persons are in the pool or garden pond.

For safety reasons, we recommend that you operate the appliance only via a earth-leakage circuit breaker (max. 30 mA).

The electrical connection of the system may only be performed by a qualified electrician. Please follow the respective national regulations!

In Austria pumps to be used in swimming pools and garden ponds should be equipped with a fixed connection line according to ÖVE B/EN 60555 Part 1 to 3; power supply should be via a ÖVE-tested isolating transformer whereby the secondary nominal voltage should not exceed 230V.

The appliance may be used by children over the age of eight and individuals with limited physical, sensory or cognitive abilities or lack of experience and knowledge if they are under supervision or were instructed regarding the safe use of the appliance and understand the resulting risks.
■ Supervise children to prevent them from playing with the appliance.

Prerequisites for the appliance's stability

Caution

Create stability for the appliance prior to all work on or with the appliance to prevent accidents or damage.

- The stability of the appliance is warranted when it is placed onto an even surface.

Operation

Please follow the safety instructions before start-up!

Description of the Appliance

1 Power cord with plug
2 Connection G1(33.3mm) Suction pipe
3 Connection G1(33.3mm) Pressure pipe
4 Filling nozzle with pre-filter
5 Pressure display
6 Drain opening
7 Backflow valve

Preparing the Appliance

Illustration A

→ Before start-up, check the pressure of the air filling in the storage boiler. If necessary, refill up to 2.0 bar in switched off / zero-pressure state.

Illustration B

→ Secure device against slipping off (fix it with screws, if needed).

Illustration C

→ Install the non-return valve.

→ Connect the vacuum-proof suction hose with integrated backflow stop on the suction side. (available as optional accessory)

→ Connect the pressure side for noise reduction to the pressure pipe via flexible hose.

Illustration D

→ To simplify the subsequent discharge and pressure release of the system, we recommend that a release cock be installed between pump and suction hose / non-return valve. (not included in delivery)

Illustration E

→ 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 leakages leads to malfunctioning.

Operation

→ Insert the mains plug into the socket.

Caution

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 enough to damage the appliance. In models BPP 4000/48 and BPP 4500/50, the supplied power is interrupted by a thermal switch if there is an overheated condition. The supplied power is switched back on after the appliance has cooled off.

We recommend installing a dry run protection unit to regulate the lack of water situation.

Caution

System is under pressure!

(For pressure details see chapter on technical specifications)

Finish operation

→ Disconnect the main plug from the socket.

Maintenance and Care

⚠️ Danger

Pull out the mains plug before doing any maintenance or cleaning jobs.

System is under pressure!

After opening the filling or drain lid or before separating the pipes, open the locking valve on the pressure side and empty the system via the drain tap (available in plumbing stores).

Care

Illustration F

→ Check pre-filter regularly for dirt. If it is visibly dirty, proceed as follows:
→ Unscrew the lid of the filling nozzle.
→ Remove the pre-filter and clean it under flowing water.

Maintenance

Illustration A

→ Check the pressure of the air filling in the storage boiler annually. If necessary, refill up to 2.0 bar in switched off / zero-pressure state (disconnect device, open the water cock).

Transport

Caution

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

When transporting by hand

→ Lift appliance by the carrying handle and carry it.

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).

Troubleshooting

⚠️ 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	Refer to Chapter "Preparation" Figure E
	Air does not come out on the pressure side	Open tap on pressure side
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 overheated.	Pull out the mains plug, let the pump cool down, clean the suction area, prevent dry running
Pump switches itself off and back on (BPP 4000/48 and BPP 4500/50)	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. Refer to Chapter "Maintenance" Figure A
	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 backflow valve contaminated	Clean suction filter or backflow valve
	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.
	Pre-filter is dirty	Remove the pre-filter and clean it under flowing water.
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 feed volume 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
