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 electri-
cal 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
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 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 or larger. Run wire from external bonding lug (see Figure 2) to rein-
forcing rod or mesh.
Wiring:
Pump must be permanently connected to circuit. Table I, Page 5, gives cor-
rect wire and circuit breaker sizes for the pump alone. If other lights or
appliances are also on the same circuit, be sure to add their amp loads to
pump amp load before figuring wire and circuit breaker sizes. (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 instruction.
In case of power outage, check GFCI for tripping (which will prevent normal
pump operation). 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.
