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.
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.
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.
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.
