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 qualied 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 nal 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
specied 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 Teon
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 lter 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 a HAYWARD-
approved agent or a qualied person.
Wear parts of the pump mentioned below should be maintained according to their estimated life:
Wear parts Estimated life
Mechanical seal 1 year
Motor bearings kit 1 year
Set of gasket (strainer, housing, bulkheads, drain) 2 years
Capacitor 2 years
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
