High Efficiency Pool and Spa Pump Installation and User’s Guide
Electrical Installation
Wiring
1. Be sure all electrical breakers, switches and automatic
controls are turned off before wiring motor.
2. Become familiar with the wiring diagram, volts, hertz,
amps and phase of your particular pump motor. All of this
information is provided on the motor nameplate label found
on the side of the motor.
3. Be sure that the supply voltage meets the requirements
listed on the motor nameplate. If these requirements are
not met, permanent motor damage may occur.
4. For wiring sizes and general guidelines for proper electrical
installation, please follow the specifications defined in the
National Electrical Code and all other applicable national
or local codes.
5. 3-Phase motors require external overload protection. An initial
inspection is needed to ensure proper rotation of the pump.
Once installed, momentarily cycle the power on and then
off. Note the rotation of the motor fan or shaft as it comes
to a stop. If wired correctly the motor shaft and/or fan will
match the rotation arrow noted on the pump.
6. Use a strain relief and be sure all electrical connections
are clean and tight.
7. Cut the wires to the appropriate length so they do not overlap
or touch when connected.
Grounding
1. Permanently ground the motor using the green ground
screw, as shown below. Use the correct wire size and type
specified by National Electrical Code. Be sure the ground
wire is connected to an electrical service ground.
2. The pump should be permanently connected to either a
circuit breaker, 2-pole timer or 2-pole relay.
Note: If AC power is supplied by a GFCI circuit breaker,
the pump should be wired on its own independent circuit
unless the pump is operated in tandem with a Pentair
salt chlorine generator.
Bonding
1. Bond the motor to the structure in accordance with the
National Electrical Code and all other applicable national
or local codes. Use a solid copper bonding conductor not
smaller than 8 AWG. For Canadian installations, a 6 AWG
or larger solid copper bonding conductor is required. Run a
wire from the external bonding screw or lug to the bonding
structure.
2. Connect the wire from the accessible bonding lug on the
motor to all metal parts of the swimming pool, spa, or hot
tub structure and to all electrical equipment, metal conduit,
and metal piping within 5 feet (1.52 meters) of the inside
walls of the swimming pool, spa, or hot tub. Run a wire from
the external bonding screw or lug to the bonding structure.
Section P/N 350486 Rev. B 6/7/17
Note: When the pump is started and stopped by removing
power with a relay or timer, a two-pole device should be
used to apply and remove power to both POWER LINE
TERMINALS.
Pentair offers GFCI breakers which offer appropriate
personal protection while meeting 2008 to current NEC
Standards for Pool Pumps. See Pentair product catalog for
details.
STORED CHARGE - Wait at least sixty (60)
seconds before servicing.
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. This pump must be installed by a licensed or certified electrician or a qualified
service professional in accordance with the National Electrical Code (NEC) and all other applicable national or local codes and ordinances.
Improper installation will create an electrical hazard which could result in death or serious injury to users, installers, or others due to electrical
shock, and may also cause damage to property.
Always disconnect power to the pump at the circuit breaker before servicing the pump. Failure to do so could result in death or
serious injury to service people, users or others due to electric shock.
Read all servicing instructions before working on the pump.

Before establishing or restoring power to the
pump, be sure all electrical connections are tight
and all electrical and wiring compartment covers are properly installed.
