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 and all applicable 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, pool users or others due to electric shock and/or property damage.
Read all servicing instructions before working on the pump.

Electrical Wiring Installation

1. Be sure all electrical breakers and switches are turned
off before wiring motor.
2. Be sure the supply line voltage matches the motor
voltage listed on the motor plate (example 230 VAC
or 115 VAC). If they do not match, permanent motor
damage may occur.
3. Use strain relief and be sure all electrical connections
are clean and tight.
4. Cut wires to the appropriate length so they don't
overlap or touch when connected to the terminal
board.
5. Permanently ground the motor using the green ground
terminal located on the inside of the motor canopy or
access plate, see Figure 1. Use the correct wire size
and type specified by National Electrical Code. Make
sure the ground wire is connected to an electrical
service ground.
6. Bond the motor to the pool structure in accordance
with the National Electrical Code. Use a solid No. 8
AWG or larger copper conductor. Run a wire from
the external bonding to the pool bonding structure.
7. 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. For Canada, a 6 AWG or larger solid
copper bonding conductor is required.
8. The pump should be permanently connected to
either a circuit breaker, 2-pole timer or 2-pole relay.
If AC power is supplied by a GFCI circuit breaker,
use a dedicated circuit breaker that has no other
electrical loads.

Pentair offers 2-Pole 20 Amp GFCI breakers
(P/N PA220GF) which offer 6 milliamp personnel
protection while meeting 2008 to current NEC
Standards for Pool Pumps.
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.
