TECHNICAL INFORMATION

1. Intended use
   The appliance is designed to pump clean water from wells or rainwater cisterns for gardening or for use in household water supply systems; these appliances may not be used for pumping drinking water. Dirt, sand and sediments are abrasive and damage the impeller. Fit suitable filters to trap these particles upstream of the pump. Chemically aggressive substances in the pumped liquid damage the appliance.
   The minimum permitted hourly flow rate is 80 l/h (1.3 l/min). These appliances are not suitable for drip irrigation systems, since the water flow rate is too low, meaning that the pumped liquid is unable to cool the appliance as required.
   The appliance must be installed in a dry, well ventilated place, protected from frost and weather, with an ambient temperature not exceeding 35°C. It must never be installed or used in the rain, in damp locations or in wells.
   The appliance conforms to the EN 60335-2-41 European standard.

2. Improper use
   Use by unskilled persons or those who have not read and understood the instructions in the manual is forbidden.
   Supplying the appliance with flammable, explosive, toxic or chemically aggressive liquids is forbidden.
   Use of the appliance in a potentially flammable or explosive atmosphere is forbidden.
   All modifications to the appliance are prohibited. Any modifications made to the appliance render the warranty null and void and relieve the manufacturer of all liability under civil and criminal law.
   Grinding and polishing substances, or other substances which attack materials, damage the appliance. These appliances are not suitable for pumped liquids containing abrasive sand, mud or clay. These appliances are suitable for pumping water for sanitary purposes, but not for pumping drinking water!
   Faecal substances may not be pumped with these appliances.

INSTALLATION

Warning – danger!
All installation and assembly operations must be performed with the appliance disconnected from the mains power supply (fig. 3).

Warning – danger!
Before use, always perform a visual check on the appliance, and especially the plug (A12) and power cable (A8), for damage. A damaged appliance must not be used; in the event of damage, have the appliance inspected by the Service Centre or an authorised electrician.

Warning – danger!
If the power cable (A8) is cut, the warranty becomes null and void and a replacement genuine power cable (A8) must be installed during the repair, at the customer’s expense (even in case of repair under warranty). If it is necessary to extend the power cable (A8), only use an extension with gauge at least equal to that of the original power cable (A8). Never lift the appliance or remove the plug (A12) from the socket by means of the power cable (A8).

Assembling the appliance
Before the appliance is put into operation, the suction and delivery hoses must be connected. Place the appliance in a stable position on a flat surface, in a location protected from flooding (fig. 4).

To prevent the transmission of vibrations to the pipes or walls, place the appliance on a rubber mat and use lengths of hose (which must be resistant to suction and pressure) immediately upstream and downstream of the appliance (fig. 5) to dampen the vibrations.

Fitting the suction hose
Warning – danger!
If your device does not have an integral pre-filter, a check valve must be installed between the suction hose and the suction fitting (A1): this valve ensures that the suction hose is not pressurised, which could cause leaks or bursts.
The suction hose conveys the water from the suction point to the appliance. Connect the suction hose to the threaded fitting (A1). Check that the suction hose fitted is airtight, since any leaks may reduce the appliance’s flow rate or completely prevent it from drawing in water. The suction hose must be at least 25 mm (1”) in diameter and must be resistant to crushing and vacuums.
Use of a suction hose with foot valve is recommended. To ensure an airtight connection, use Teflon tape (12 – 15 layers) (fig. 6). Make sure that there is sufficient water in the suction point and that the hose suction zone is permanently below the water level.

Since the maximum suction lift of self-priming pumps is 8 metres, the appliance must be no more than 8 m above the water level in the suction point. The horizontal part of the suction hose must rise continually from the suction point to the appliance, to prevent the formation of air bubbles in the hose, which could impair operation of the appliance (fig. 7).

A pre-filter must be installed between the suction hose and the suction fitting (A1), unless the appliance has an integral pre-filter (A1 b).

Filling the appliance
Before fitting the delivery hose, completely fill the pump body (A4) and the suction hose with water through the delivery fitting (A2). The pump can also be filled through the filler cap (A2 b), if present (fig. 8).
Bubbles form during filling of the pump body (A4) and must be discharged by tilting the appliance slightly in various directions. Fill again and repeat this procedure until
the water level is just below the filling hole.
If the appliance has an integral pre-filter, more water must be added through the cap of the pre-filter (A1 b). Open the cap, fill with water to the rim and screw the cap back on by hand (fig. 8).

Fitting the delivery hose
The delivery hose fitting is on the top of the appliance (A2). The hose should be connected to a hose or pipe with the largest possible diameter (at least 19 mm, ¾”). Smaller diameters drastically reduce the appliance’s flow rate. To ensure an airtight connection, use Teflon tape (12 – 15 layers) (fig. 9).

In a household pumping system, the connected pipes are permanently pressurised. Therefore, we recommend the use of a reinforced hose, capable of withstanding this permanent pressure, when connecting to a permanent distribution system.

Warning – danger!
The use of garden hoses or suction hoses on the appliance’s delivery side is not permitted if the pipes are permanently pressurised, since the continuous pressure combined with wear and fatigue of the materials may cause them to burst or tear even after only a short time. Garden hoses may only be used when not permanently pressurised, e.g. when they are installed downstream of a stop valve or a water supply tap, and only ever outdoors.

Safety Measures
The user must prevent damage arising from the flooding of premises or other causes in the event of a failure of the appliance or external components by adopting suitable measures (e.g. installation of an anti-flooding protection circuit, alarm system, backup pump, collection tank or similar features), which must be connected to a separate, fail-safe electrical circuit. The safety measures must be suited to the specific conditions of use and must be able to reduce and/or prevent the damage caused by water leaks.

The user must also install a spray guard to prevent water leaks or splashes due to a pump failure from causing damage. A backup pump or a floor drain must be installed to ensure that any water from leaks is promptly removed. Otherwise, an alarm system can be installed to trigger an alarm and/26 or an emergency shut-down of the appliance and water supply in the event of a water leak, before damage to the equipment or property can occur.
We also recommend raising all equipment in appliance installation rooms about 5-10 cm above the floor so that any water leaks will not cause immediate damage. The manufacturer accepts no liability for damage caused by failure to comply with this recommendation.

Warning – danger! Dry operation
If the appliance runs for more than 5 minutes with the water suction point closed, it may be damaged due to overheating. Switch off the appliance when the normal water flow is obstructed.
Dry operation will damage the appliance beyond repair, so never allow it to run dry for more than 10 seconds.

ADJUSTMENTS

Preliminary adjustments
Our appliances are preset in the factory and users must not modify these settings.

START-UP

Warning – danger!
All installation and assembly operations must be performed with the appliance disconnected from the mains power supply (fig. 3).

1. Start-up
   Once all the pipes have been connected and the pump body (A4) is full of water, the plug (A12) can be connected and the ON/OFF switch (A5) turned to ON. During the priming phase, the delivery pipe must be open to allow the air in the system to escape and to enable the water pressure to build up. If the suction hose is not completely full of water, it may take the appliance up to 7 minutes to become fully operational. If the water has not pressurised after the maximum priming time stated, switch the appliance off and proceed as described in the troubleshooting plan (chapter 11).

2. Technical information
   The appliance’s stated flow rate values are maximum values, which are reduced if external components (e.g. delivery hose, elbows, pre-filter, etc.) are used. This should be borne in mind when choosing the appliance. The actual flow rate for specific installation conditions is stated in the flow rate graph (fig. 11)
   

MAINTENANCE

Warning – danger! The system is pressurised!
Before any maintenance procedure and/or during troubleshooting, disconnect the power cable (A8) from the socket.
Check that the connection hoses or the appliance’s tank (A10) are not still pressurised. To ensure this, turn on a user (water supply tap) and drain all the water from the system. All maintenance and cleaning work can then be carried out.

Checking the pressure in the tank (A10)
To ensure that the appliance operates correctly, the pressure in the tank (A10) must be checked at regular intervals (3-4 times a year); it must be 1.5 bar. To check the pressure, unscrew the valve cap (A9 b) on the tank (A10) and check the pressure by connecting an air pump with pressure gauge to the valve (A9) (fig. 10). If the pressure is less than 1.5 bar, restore it to that value.

Insufficient air pressure causes the appliance to malfunction and leads to wear of the rubber diaphragm in the tank (A10). Any damage to the appliance caused by incorrect pressure in the tank (A10) is not covered by the warranty.

STORAGE

Warning – danger! The system is pressurised!
Before any maintenance procedure and/or during troubleshooting, disconnect the power cable (A8) from the socket.

Check that the connection hoses or the appliance’s tank (A10) are not still pressurised. To ensure this, turn on a user (water supply tap) and drain all the water from the system. All storage procedures can then be carried out.

It is essential to protect the appliance from frost, and in case of temperatures of +5°C or below it must be uninstalled and stored in a dry place, protected from frost. After disconnecting the suction and delivery hoses, unscrew the drain plug (A3) and tilt the appliance to drain out all the water in the tank (A10). To empty the pump body (A4) turn the appliance upside down to drain the water from the delivery fitting (A2).
