USE ONLY GENUINE REPLACEMENT PARTS

GENERAL POINTS

• Install the pump at a suitable distance from the pool to reduce the distance between the suction point and the pump as much as possible to avoid pointless excessive pressure drops on the hydraulic circuit. However, it is essential to comply with the safety distance required by the current installation standard (3.5 metres minimum). Install and use the product at an altitude less than 2000m
• Install the pump in a dry, well-ventilated place. The motor requires the air to circulate freely around it to allow natural ventilation. Check regularly that no objects, leaves or other debris are blocking the motor cooling system.
• The pump must be installed to ensure that the external disconnection switch incorporated into the fixed unit is visible and easily accessible. The switch must be located near to the pump.
• The pump must be permanently installed on a concrete base using 8mm lag screws suitable for concrete, screwed into drilled implantation holes. Lock washers must be used to prevent the installation lag screws working loose over time. If the pump has to be mounted on a wooden board, Ø 8mm hexagonal wood screws must be used combined with lock washers to prevent the screws working loose over time.
• The acoustic pressure of pumps is less than 70 dBA.

Necessary measures:

• Connect the pump to the earth: Never operate the pump unless it is connected to the earth.
• Connect the pump with a flexible cable 3G1.5mm² for single-phase pumps and 4G1mm² for three-phase pumps, type H07RN-F.
• Include a 30mA differential protection to protect people against electric shocks which may be caused by a breach of the equipment’s electrical insulation.
• Include short-circuit protection (the rating is determined according to the value given on the nameplate on the motor).
• Include a means of disconnection from the power supply having an opening distance on the contacts of all the poles ensuring the power supply is completely cut off under the conditions of a category III overvoltage.

Single phase electric motor:
The single phase motors fitted to our pumps are provided with thermal protection. This protection operates on an over-load or in the event of abnormal heating of the motor coil and is reset automatically when the winding temperature drops.

Three phase electric motor:
Check the running direction of the pump motor (a label is provided on the motor housing to indicate the motor running direction).
Whatever the motor type, in addition to the devices mentioned above, it is also necessary to install a thereto-magnetic protective device GV2ME or of similar features, calibrated in accordance with the indications on the motor name-plate. The table on page 28 indicates the various characteristics of the motors fitted to our pumps.

Electrical connection:

• Make sure that the power supply voltage required by the motor corresponds to that of the distribution network and that the power supply cables matches the power and current of the pump.
• All the electric connections of the pump and the possible change of power supply cable must be hand-led by a qualified professional so as to avoid all possible danger. When making these electrical connections, refer to the diagram given under the lid of the motor terminal box.
• Be sure to check the electric connections are tight and sealed before powering up.
• The pre-wiring that might be included on some of the pumps must be removed for final connection of the pump to the electric power supply. This pre-equipment is only used for works testing during the manufacturing phases.

INSTALLATION

• Install the pool pump so as to reduce pressure drops to a minimum whilst complying with the distances specified in the installation standard, namely 3.5m minimum between the pump and the pool. The suction pipe must be installed with a slight uphill incline towards the pump axis. Ensure that the connections are correctly tightened and watertight.
• However, avoid excessively tightening the pipes. For plastic materials, use Teflon only to ensure watertightness. The diameter of the suction pipe shall depend on that of the discharge pipe. Avoid damp or non-ventilated locations. The motor requires the cooling air to circulate freely.
• IMPORTANT: Check the direction of rotation before permanently connecting the motor.
• INSTRUCTIONS FOR START-UP AND PRIMING: Fill the body of the strainer with water up to the level of the suction pipe. Never run the pump without water, as the water is necessary for cooling and lubrication of the mechanical shutter. Open all the suction and discharge pipe valves, and the filter air purge valve if there is one. (Any air in the suction pipes must be eliminated). Start up the generator and wait a reasonable time for priming. Five minutes is not excessive for priming (this time depends on the suction head and the length of the suction pipe). If the pump does not start or does not prime, please refer to the troubleshooting guide.

MAINTENANCE

1. Completely disconnect the pump from the mains power supply before opening the cover and cleaning the strainer. Clean the strainer basket regularly. Do not bang on the basket to clean it. Check the seal on the cover of the strainer and replace it if necessary.
2. The motor shaft is mounted on self-lubricating bearings which do not require any subsequent lubrication.
3. Keep the motor clean and dry and ensure the ventilation openings are not blocked.
4. The mechanical seal occasionally starts to leak and must then be changed.
5. Apart from cleaning the pool, all repairs, servicing and maintenance must be carried out by approved agent or a qualified person.

Wear parts of the pump mentioned below should be maintained according to their estimated life:

Wear parts Estimated life

• Mechanical seal 2 years or 10.000 hours.
• Motor bearings kit 2 years or 10.000 hours.
• Set of gasket (strainer, housing, bulkheads, drain) 2 years or 25.000 hours.
• Capacitor 2 years or 10.000 hours.

WINTERING

1. Empty the pump by removing all the drain plugs and store them in the strainer basket.
2. Disconnect the pump, remove the pipe connectors and store the entire unit in a dry, well-ventilated place or at least take the following precaution: disconnect the pump, remove the 4 bolts attaching the pump housing to the motor bracket and store the unit in a dry, well-ventilated place. Then cover the pump housing and strainer to protect them.
   N.B.: Before recommissioning the pump, clean all the internal parts to remove dust, lime scale, etc.

TROUBLESHOOTING

1. The motor does not start:

2. Check the electrical connections, switches or relays, and the circuit breaker or fuses.

3. Ensure that the motor turns freely by hand.

4. The motor stops, check:

5. The cables, connections, relays etc.

6. Voltage drop on motor (frequently caused by cables that are too small).

7. That there is no seizing or overheating (by reading the absorbed current).

8. The motor growls but does not start, check that a phase is not cut, the capacitor is not damaged.

9. The pump does not prime:

10. Ensure the strainer housing is filled with water, that the cover seal is clean and correctly positioned and that no air can enter. If necessary, tighten the cover lock screws.

11. Ensure that all the suction and discharge valves are open and not blocked and that the suction outlets in the pool are fully submerged.

12. Check that the pump draws by freeing the suction as close as possible to the pump:

13. If the pump does not draw despite being sufficiently full of priming water

14. Tighten the bolts and pipe accessories on the suction side.

15. Check the voltage to ensure that the pump is rotating at the correct speed.

16. Open the pump and check that nothing is blocking it inside,

17. Replace the mechanical shutter.
    If the pump is drawing normally, check the suction pipe and strainer which may be blocked or be allowing air to enter.

18. Low flow – Generally, Check for:

19. Clogged or restricted strainer or suction line; undersized pool piping.

20. Plugged or restricted discharge line of filter (high discharge gauge reading).

21. Air leak in suction (bubbles issuing from return fittings).

22. Pump operating under speed (low voltage).

23. Plugged or restricted impeller.

24. Noisy pump, check:

25. That no air is entering the suction side and causing dull crackling in the pump.

26. That there is no cavitation caused by insufficient diameter or a restriction in the suction tube. An oversized discharge pipe can also cause cavitation. Use pipes of the correct size or purge the pipes if necessary.

27. That no vibration is occurring due to incorrect fitting.

28. That there are no foreign bodies in the pump housing.

29. That the motor bearings have not seized due to excessive clearance, rust or prolonged overheating.
