Applications & Compatibility
This motor is ideal for replacing older or worn motors on pool pumps that use a 56Y square flange motor mount. It’s especially suited for in-ground pump systems that call for a two-speed option—high speed for full flow and low speed for quieter, energy-saving operation. Before purchase, verify mounting type, shaft configuration, electrical rating and pump model compatibility.
Installation Instructions
- Turn off main power to the pool pump and lock out the circuit before servicing.
- Drain or relieve pump housing pressure, disconnect the wiring according to motor wiring diagram.
- Remove the old motor, keeping the same mounting configuration and note shaft spacing and alignment.
- Mount the new B2983 motor using the square flange holes, ensure shaft engages pump coupling correctly.
- Wire the motor per label instructions for desired speed (high or low), restore power and test operation in both modes.
Troubleshooting
- Motor fails to start: Verify correct wiring, check capacitor (if applicable), ensure correct voltage supply.
- Pump vibration or noise: Confirm shaft alignment, pump impeller clearance, tight mounting bolts and balanced rotor.
- Low flow on low speed mode: Ensure plumbing and filter are clean, pump impeller is sized appropriately for low-speed operation.
Maintenance Tip
Check motor mounting bolts, pump alignment and cleanliness annually. Lubricate any required parts if applicable, ensure motor is ventilated and free of debris. Replacing worn bearings or coupling during motor changeover helps protect the new B2983 from premature wear.
