Danger!
When using the equipment, a few safety pre-cautions must be observed to avoid
injuries and damage. Please read the complete operating instructions and
safety regulations with due care. Keep this manual in a safe place, so that
the in-formation is available at all times. If you give the equipment to any
other person, hand over these operating instructions and safety regulations as
well. We cannot accept any liability for damage or accidents which arise due
to a failure to follow these instructions and the safety instructions.
Safety regulations
Danger!
This equipment is not designed to be used by people (including children) with
limited physical, sensory or mental capacities or those with no experience
and/or knowledge unless they are su-pervised by a person who is responsible
for their safety or they have received instructions from such a person in how
to use the equipment safely. Children must always be supervised in order to
ensure that they do not play with the equipment.
- Please read the directions for use carefully and observe the information provided. It is important to consult these instructions in or-der to acquaint yourself with the machine, its proper use and safety precautions.
- Suitable measures must be taken to keep the equipment out of the reach of children.
- The operator is responsible for the safety of third parties present in the work area.
- Before starting, a test must be carried out by a specialist to ensure that the required electrical safety measures are in place.
- There must be no personnel in the transport medium while the pump is operating.
- Caution! In stagnant water, garden ponds, swimming ponds and their surrounding areas the pump may only be used with an earth-leakage circuit breaker with an actuating ra-ted current of up to 30mA (according to VDE 0100 part 702 and 738).
- Always inspect the equipment visually before using it. Do not use the equipment if safety devices are damaged or worn. Never disable safety devices.
- Use the equipment only for the purposes indicated in these directions for use.
- You are responsible for safety in the work area.
- If the plug is damaged by external influences, the cable may not be repaired. The cable must be replaced by a new one. This work may only be carried out by a trained electrician.
- The voltage of 230 V alternating voltage specified on the rating plate must be the same as the mains voltage.
- Ensure that the electrical plug connections are in areas that are not at risk of flooding or protect them from moisture.
- Pull the mains plug before starting any work on the equipment.
- Do not expose the equipment to a direct jet of water.
- The operator is responsible for complying with local safety and installation regulations (ask an electrician if you are in any doubt).
- Consequential damage caused by flooded rooms in the event of the pump suffering faults must be prevented by the user by means of suitable measures (for example installing alarm systems or a reserve pump, etc.).
- Should the tool experience problems beyond those mentioned above, let only an authorised professional or a customer service shop perform an inspection.

Proper use
Suitable for use for the domestic water supply in a house or garden. Ideal for
converting irrigation pumps into an automatic domestic water system. The
electronic fl ow switch with dry running guard switches on the pump
automatically when water is needed. When the water supply has been stop-ped,
the pump switches off again. Easy to fi t to any garden pump with a 33.3 mm (R1)
connector. Easy to connect due to its ready-fi tted mains lead and socket.
Please note that our equipment has not been de-signed for use in commercial, trade or industrial applications. Our warranty will be voided if the machine is used in commercial, trade or industrial businesses or for equivalent purposes.
Technical data
Mains voltage: …………………………. 230 V~ / 50 Hz
Max. current strength: ……………………………..10 A
Protection type: …………………………………….. IP 44
Max. operating pressure:…………1.0 MPa (10 bar)
Max. temperature: …………………………………. 55°C
Installation and start-up
Switch off the pump and pull the pump’s mains plug. Remove the existing output line on the actu-al pump. Ensure that you bleed the pump correct-ly (refer to the pump’s manual for further details). Screw the connection adapter (Fig. 1 / Item 4) to the output line connector on the pump (Fig 3). Fit the fl ow switch (Fig. 1 / Item 1) with the con-nection thread (Fig. 2 / Item 5) to the connection adapter and secure it to the connection adapter using the union nut (Fig. 4 / Item 10) (Fig. 4). The fl ow switch must be in an upright position, in other words the connector for the pump (Fig. 2 / Item 5) must be at the bottom and the connector for the output line (Fig. 2 / Item 6) must be at the top. If it is in any other position, the fl ow switch cannot work correctly. Raise the non-return valve at the handle (Fig. 2 / Item 7) (Fig. 5) and carefully fi ll the fl ow switch with the transport fl uid up to the bot-tom end of the thread on the pressure connector (Fig. 2 / Item 6) to prevent the system running dry. Now screw the output line to the connector pro-vided for it (Fig. 2 / Item 6) on the fl ow switch and ensure that you seal the connection properly, for example with Tefl on tape (not supplied). Connect the pump’s mains plug to the socket (Fig. 1 / Item 2) on the rear of the fl ow switch. After checking all the connections and lines, connect a consumer to the output line and open it so that any air in the output line can escape when the transport process is started. Connect the mains lead (Fig. 1 / Item 3) on the fl ow switch to an adequately fused (at least 10 A) 230 V ~ 50Hz safety mains socket with a ground contact. The flow switch is now ready for use. Switch on the pump if it is fi tted with a switch, otherwise the pump will now start automatically and will start to transport the medium. The consumer can be closed as soon as the transport fluid is emitted from it. The fl ow switch will now switch off the socket (Fig. 1 / Item 2). To dismantle, proceed in reverse order. If you place it into storage, ensure that the flow switch does not contain any transport fluid so as to avoid frost damage.
Operation
The flow switch cannot be adjusted or switched, it is fully automatic. There are only 3 LEDs (Fig. 2 / Item 8) to indicate its operating status.
Green LED:
The flow switch is connected to the power supply
Yellow LED:
The flow switch has tripped, the socket (Fig. 1 / Item 2) is live.
Red LED:
The fl ow switch has detected a fault
The following operating statuses are indicated:
Green is lit:
The flow switch is ready for use, no transport fluid is required. The pump is
not running.
Green and yellow are lit:
The pump is operating, a consumer for dischar-ging transport fl uid is open.
Green and red are lit:
The pump is running dry without transport fl uid. The fl ow switch will attempt
to rectify the dry running three times before the dry running guard finally
trips.
Green is lit, red is flashing:
The dry running guard has tripped, it is no longer possible to draw in the
transport fluid. Find the cause of the fault using the pump’s operating manual
(for example leaking intake line) and rectify it. Then restart the pump by
pressing the Reset button (Fig. 2 / Item 9) on the flow switch.
Replacing the power cable
Danger!
If the power cable for this equipment is damaged, it must be replaced by the
manufacturer or its after-sales service or similarly trained personnel to
avoid danger.
Maintenance
The flow switch requires no maintenance. The only requirement is for regular checks on the screw connections and line to ensure that they are correctly positioned, secure and not leaking so that error sources can be identified and rectified as soon as possible.
