• WARNING – This appliance is not intended to be used by people (particularly children) with reduced physical, sensory or mental capabilities or by those lacking in experience or knowledge, unless they have been instructed in the use of the appliance or are under the supervision of a person responsible for their safety.

• WARNING – Do not allow children to play with the appliance.

• WARNING – Keep all foreign bodies, fingers and any other parts of the body away from openings and moving parts.

• WARNING – Only use genuine Hayward spare parts.

• WARNING – If the power cable is damaged, it must be replaced by the manufacturer, the manufacturer's after-sales service or persons with a similar qualification to avoid any danger.

• WARNING – Ensure the pump is connected to a 230V socket with short circuit protection. The pump must also be powered via an isolation transformer or a residual current device (RCD) for which the residual rated operating current does not exceed 30mA.

• WARNING – Completely disconnect the pump from the mains power supply before opening the cover and cleaning the strainer.

• WARNING – To disconnect the pump from the mains power supply, an external switch with contact separation on all the poles ensuring complete disconnection in the event of category III overvoltage must be integrated into the fixed unit in accordance with the rules applicable to wiring.

• WARNING – The pool pump must never be started if the power cord or the housing of the motor control unit are damaged, as there is a risk of electric shock. A damaged power cord or motor control unit must be replaced immediately by an approved technician or qualified person to prevent any risk.

• WARNING – This motor is NOT fitted with an SVRS (Safety Vacuum Release System). The SVRS helps to prevent drowning if people find themselves trapped against the outlet pipe under the surface of the water. In some swimming pool configurations, if the body of a person blocks the outlet pipe, the person risks being trapped by the suction. Depending on the configuration of your pool, local regulations may require the installation of an SVRS.USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Page 3 of 12 Pump Rev B GENERAL POINTS Congratulations, you have just acquired a Hayward variable speed pump

have a state-of-the-art permanent-magnet motor with AC electronic switching. This motor is controlled by a microprocessor combined with a frequency variator providing the following characteristics:

• Rotation speed is displayed on the control display

• 3 factory preset rotation speeds (buttons V1, V2, V3), as well as custom speeds set by the user

• Regular priming each time you switch on, with adjustable speed and duration

• Skimmer function, which skims the water's surface

• Partial and total power consumption displayed

• Construction standard TEFC IP55 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 m minimum). Install and use the product at an altitude less than 2000 m ZONE 2 ZONE 2 ZONE 0 1,50 m 2,50 m 2,50 m 1,50 m 2,00 m 2,00 m 1,50 m ZONE 1 1,50 m

ZONE 0 Install the pump in a dry, well-ventilated place. The motor requires the air to circulate freely around it to allow natural ventilation. Clear a space of at least 0.5m around the pump. 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 8 mm hexagonal wood screws must be used combined with lock washers to prevent the screws working loose over time. Install the pump under shelter to avoid the control unit being subject to heavy splashing. The acoustic pressure of Hayward pumps is less than 70 dB (A). Necessary measures:

• Connect the pump to the earth: Never operate the pump unless it is connected to the earth.

• Connect the pump with a H07RN-F 3G1mm² type cable (D max 7,8mm)

• Include a 30 mA 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.

WARNING: Wait 5 minutes after having totally disconnected the pump from the power supply before carrying out any

operation on the motor or the connection box: Danger of electric shock which may cause death. The electric motors fitted to our pumps have thermal protection. This protection reacts in the event of overload or abnormal temperature rise in the motor winding. This protection automatically resets when the winding temperature drops. Whatever the type of motor used, if the regulations require it, a magnetic thermal protection must be installed in addition to the measures described above, which must be calibrated according to the information on the motor's nameplate. The table on page 145 gives the various characteristics of the motors fitted to our pumps.USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Page 4 of 12 Pump Rev B Electrical connection: Ensure that the supply voltage required by the motor corresponds to that of the distribution network and that the section and length of the power cable are adapted to the power and current of the pump. All the electrical connections on the pump and any change of power cable must be done by a qualified professional to avoid any danger. When carrying out the electrical connections, comply with the identification under the connection terminals. Check that the electrical connections are correctly tightened and watertight before switching on the power. Ensure the cable runs correctly through the opening and ferrite provided for this purpose. The cable gland ensures watertightness around the cable, and the ferrite acts as a filter against electromagnetic disturbance. Any pre-wiring on our pumps must be removed when the pump is permanently connected to the power supply. This preparation is only used for testing at the factory 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. Install the pump under shelter to avoid the control unit being subject to heavy splashing. 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.

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 shutter 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 a Hayward-approved agent

or a qualified person. 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 A) The motor does not start

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

2. Ensure that the motor turns freely by hand.

3. Check that rotation speeds V1, V2 and V3 are not programmed at 0rpm. If they are, restore the factory settings (see

Err01 Constant low line voltage Err10 Internal problem with electrical supply Err02 Constant high line voltage Err20 Starting problems Err04 Power module overheating Err64 Internal short-circuiting problem Err05 Motor overheating Err97 Multiple problems Err07 Overload Err98 Communication problem B) The motor stops, check

1. The cables, connections, relays etc.

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

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

N.B.: The motor on your pump is fitted with a thermal protection which, in the case of overload, will automatically cut the circuit and avoid the motor being damaged. This triggering is caused by abnormal usage conditions which need to be checked and corrected. The motor will restart without any intervention as soon as normal operating conditions are restored. C) "OLOAD" appears on the display (overload or over-heating problem)

1. Check that the motor shaft turns freely

2. Check that no debris is preventing the turbine from rotating freely

3. Check that the motor is correctly ventilated

4. After correcting the problem, press the On/Off button

D) The pump does not prime 1. 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. 2. Ensure that all the suction and discharge valves are open and not blocked and that the suction outlets in the pool are fully submerged.USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Page 12 of 12 Pump Rev B TROUBLESHOOTING (CONTINUED)

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

a) if the pump does not draw despite being sufficiently full of priming water

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

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

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

4. Set a priming speed that is fast enough

5. Clean the filter and try again

6. Replace the mechanical shutter.

b) Try priming in re-circulation mode. If the pump is drawing normally, check the suction pipe and strainer which may be blocked or be allowing air to enter. E) Noisy pump, check

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

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

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

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

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