3.2
Electrical Installation
3.2.1 Voltage Checks
The correct voltage, as specified on the pump data
plate, is necessary for proper performance and long
motor life. Incorrect voltage will decrease the pump's
ability to perform and could cause overheating, reduce
the motor life, and result in higher electric bills.
It is the responsibility of the electrical installer to
provide data plate operating voltage to the pump by
ensuring proper circuit sizes and wire sizes for this
specific application.
CAUTION
Failure to provide data plate voltage (within 10%)
during operation will cause the motor to overheat
and void the warranty.
3.2.2 Bonding and Grounding
1.
The motor frame must be bonded to a reliable
grounding point using a solid copper conductor,
No. 8 AWG or larger. In Canada, No. 6 AWG or
larger must be used.
2.
Bond the motor using the provided external
lug.
WARNING
Always disconnect the power source before
working on a motor or its connected load.

WARNING
Ensure that the control switch or time clock is
installed in an accessible location so that in the
event of an equipment failure or a loose plumbing
fitting the equipment can be turned off. This
location must not be in the same area of the pool
pump, filter, and other equipment.
CAUTION
The pump must be permanently connected to a
dedicated electrical circuit. No other equipment,
lights, appliances or outlets may be connected
to the pump circuit.
3.2.3 Electrical Wiring
1.
The pump motor must be securely and adequately
grounded using the green screw provided.
Ground before attempting to connect to an
electrical power supply. Do not ground to a gas
supply line.
2.
Wire size must be adequate to minimize voltage
drop during the start- up and operation of the
pump. See Table 2 for suggested wire sizes.
3.
Insulate all connections carefully to prevent
grounding or short-circuits. Sharp edges on
terminals require extra protection. Tape wire
nuts to prevent loosening. For safety, and to
prevent entry of contaminants, reinstall all
conduit and terminal box covers. Do not force
connections into the conduit box.
4.
To configure the pump motor internal wiring for
the correct voltage, refer to the diagram on the
motor data plate.
