3 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. Before wiring the pump, ensure all power on the pump's circuit is turned off at the circuit breaker. STORED CHARGE - Wait at least 60 seconds before servicing. 2. Become familiar with the wiring diagram and electrical specifications of your particular pump motor. This information is provided on the motor nameplate label found on the side of the motor. 3. Ensure the supply voltage meets the requirements listed on the motor nameplate label. If these requirements are not met, permanent motor damage may occur. 4. For wiring sizes and general guidelines for proper electrical installation, 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 ensure all electrical connections are clean and tight. 7. Cut all 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. Use the correct wire size and type specified by National Electrical Code. Ensure 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 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 pump's bonding screw or lug to the bonding structure. 2. Connect the bonding wire to all metal parts of the pool structure and to all electrical equipment, metal conduit and metal piping within 5 ft. (1.5 m) of the inside walls of the pool. 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.
