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 Hayward pumps is less than 70dB (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 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 overload
or in the event of abnormal heating of the motor coil and is reset automatically when the winding temperature drops.
Three phase electric motor:
On three phased motors the internal heat protection (screw terminal blocks ) is to be connected serially in the pump’s
power contactor command line.
Check the running direction of the pump motor (a label is provided on the motor housing to indicate the motor running
direction).
If so required by regulations and whatever the motor type, in addition to the devices mentioned above, it is also necessary
to install a thereto-magnetic protective device calibrated in accordance with the indications on the motor name-plate.
The table on page 108 indicates the various characteristics of the motors fitted to our pumps.
