Installation Notes
Disconnect power and lock out the circuit before servicing. Remove the existing motor by unmounting the thru-bolt pump bracket, disconnect wiring, and extract the motor. Verify the shaft and mounting dimensions match. Install the new BN25V1 motor, connect wiring per the motor’s wiring diagram, secure the pump housing and shaft seal, restore power, prime the system, and verify correct motor operation without vibration or excessive heat.
Maintenance Tip
During each service interval inspect motor bearings for noise or vibration, check the shaft seal and mounting bolts for tightness, and verify current draw remains within spec. Replace the motor if you observe sustained high temperature, excessive noise or flow issues to maintain efficient pump system performance.
