ELECTRICAL
Ground motor before connecting to electrical power supply. Failure to
ground motor can cause severe or fatal electrical shock hazard.
Do not ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn OFF power to motor
before working on electrical connections.
Ground Fault Circuit Interrupter (GFCI) tripping indicates an electrical
problem. If GFCI trips and will not reset, have a qualified electrician
inspect and repair electrical system.
Exactly match supply voltage to nameplate voltage. Incorrect voltage
can cause fire or seriously damage motor and voids warranty.
If in doubt consult a licensed electrician.
Voltage
Voltage at motor must be not more than 10% above or below motor name-
plate rated voltage or motor may overheat, causing overload tripping and re-
duced component life. If voltage is less than 90% or more than 110% of rated
voltage when motor is running at full load, consult power company.
Grounding/Bonding
Install, ground, bond and wire motor according to local or National Electrical
Code requirements.
Permanently ground motor. Use green ground terminal provided under motor
canopy or access plate (See Figure 2); use size and type wire required by
code. Connect motor ground terminal to electrical service ground.
Bond motor to pool structure. Use a solid copper conductor, size No. 8 AWG
(8.4 sq.mm) or larger. Run wire from external bonding lug (see Figure 2) to re-
inforcing rod or mesh.
Connect a No. 8 AWG (8.4 sq.mm) solid copper bonding wire to the pressure
wire connector provided on the motor housing and to all metal parts of the
swimming pool, spa, or hot tub and to all electrical equipment, metal piping
or conduit within 5 feet (1.5 m) of the inside walls of swimming pool, spa, or
hot tub.
Wiring
Pump must be permanently connected to circuit. Match wire and circuit
breaker sizes to Table I (Page 5). If other lights or appliances are also on the
same circuit, be sure to add their amp loads to pump amp load. (If unsure how
to do this or if this is confusing, consult a licensed electrician.) Use the load
circuit breaker as the master on-off switch.
Install a Ground Fault Circuit Interrupter (GFCI) in circuit; it will sense a short-
circuit to ground and disconnect power before it becomes dangerous to pool
users. For size of GFCI required and test procedures for GFCI, see manufac-
turer’s instructions.
In case of power outage, check GFCI for tripping (which will prevent normal
water circulation). Reset if necessary.
NOTICE: If you do not use conduit when wiring motor, be sure to seal wire
opening on end of motor to prevent dirt, bugs, etc., from entering motor.
