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.

WATERFALL™ Specialty Pump Installation and User's Guide

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.
