Installation Information

Installation requires proper three-phase electrical service and correct motor wiring for the available supply voltage. Wiring configuration must match the motor nameplate and applicable electrical codes.

Electrical installation and pump servicing should be performed by a qualified pool professional or licensed electrician. Always disconnect and lock out electrical power before servicing the pump.

Inspect the mechanical seal, impeller, seal plate, O-rings, and related pump components when replacing the motor. Worn sealing components should be replaced as necessary to help prevent water leakage into the new motor.
