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 76.1 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 H07RN-F 3G1,5mm² type cable.
• 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.
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 17 gives the various characteristics of the motors fitted to our pumps.
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.
