ELECTRICAL
Ground motor before
connecting to electrical
power supply. Failure to
ground motor can cause se-
vere 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 be-
fore working on electrical
connections.
Ground Fault Circuit
Interrupter (GFCI) trip-
ping 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 dam-
age motor and voids warranty. If in doubt consult a li-
censed electrician.
Voltage
Voltage at motor must be not more than 10% above or
below motor nameplate rated voltage or motor may over-
heat, causing overload tripping and reduced 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
3); 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 con-
ductor, size No. 8 AWG (8.4 sq.mm) or larger. Run wire
from external bonding lug (see Figure 3) to reinforcing
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 6). 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
manufacturer’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.
Risk of dangerous or fatal electrical shock.
Be sure that power to the motor circuit is off before
working on wiring, wiring connections, or motor. Re-in-
stall the motor end cover and all other wiring covers be-
fore turning on the power.
1. Turn off power.
2. Remove the motor end cover.
