Electrical Connection - Hayward SP1800 Serie Manual Del Usuario

GENERAL
All pool electric pump installations need to be carried out according to professional practice rules and in com-
pliance with the current standards (p 24).
Install the pump at the right distance from the base in to minimize the link at length between the suction point
and the pump so as to do away with pointless and excessive load losses in the hydraulic circuit.
However, it is mandatory to allow a safety distance as required by the current installation standard (p 24).
Install the pump in a ventilated and dry place. The motor requires air to flow freely around it to provide for
natural ventilation.
The pumps must be installed in a fixed station.
The acoustic level of the Hayward pumps is lower than 70 dB (A).
Warning:
This appliance is not intended for use by persons (including children) with reduced physical, sensory or men-
tal capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.
Necessary arrangements :
• Connect the pump to ground
• Fit a 30 mA differential protection device to protect people from electric shock caused by a possible break
in the electrical insulation.
•
Provide protection against short-circuiting (the definition of the rating will depend on the value indicated
on the motor name plate).
•
Provide a circuit separation device with a 3 mm opening on all the poles.
Single phase electric motor: The single phase motors fitted to our pumps are provided with thermal protec-
tion. 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: A protection has to be connected to the terminals of the motor and to the power
supply cutoff device of the pump.
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 23 indicates the various characteristics of the motors fitted to our pumps.

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.
