GENERAL POINTS
Congratulations, you have just acquired a Hayward variable speed pump
®
.
Hayward variable speed pumps
®
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
• Programmable Timer function
• Current power usage displayed
• Partial and total power consumption displayed
• Running time of the pump displayed
• Low noise level
• 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

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 169 gives the various characteristics of the motors fitted to our pumps.
