Testing and Certification
Suction outlet covers must have been tested by a
nationally recognized testing laboratory and found to
comply with the latest ASME/ANSI Specifications for
Suction Fittings For Use in Swimming Pools, Spas, Hot
Tubs, and Whirlpool Bathtub Applications.
Fittings:
Fittings restrict flow; for best efficiency use fewest
possible fittings (but at least two suction outlets).
Avoid fittings which could cause an air trap.
Pool fittings must conform to International Association
of Plumbing and Mechanical Officials (IAPMO)
standards.
Use only non-entrapping suction fitting or double suction.
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 nameplate 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 all
current local or the current National Electrical Code
requirements.
Permanently ground motor. Use green ground terminal
provided under motor canopy or access plate (See
Figure 4) ; 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 4 ) to reinforcing
rodormesh.
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
NOTICE: 3 phase models require magnetic motor
starters and external overload protection. If in doubt
about the procedure, consult a licensed electrician.
Pump must be permanently connected to circuit. Table
I, Page 6, give correct 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.
