Installation Notes
Disconnect power and lock out the circuit. Remove the pump and old motor, ensure the new motor matches frame, shaft and mounting configuration. Mount motor to the pump housing using square flange, align coupler or impeller as required, connect wiring based on voltage label, restore power and monitor current draw, flow and vibration during startup.
Maintenance Tip
During annual pump service, check motor bearings for smooth rotation, inspect for excess vibration or heat, verify wiring connections and ensure proper cooling. Replacing the motor when symptoms begin—rather than waiting for failure—helps avoid unscheduled downtime and protects associated equipment.
