Electrical Installation
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.

Wiring

1. Be sure all electrical breakers, switches and automatic
controls are turned off before wiring motor.
STORED CHARGE - Wait at least sixty
(60) seconds before servicing.
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.
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.
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.
