Installation & Compatibility Notes
Verify that your existing pump motor uses a 48Y square-flange mounting pattern and square-flange bolt‐hole layout. Ensure voltage compatibility (115 V or 230 V) with the motor wiring configuration. When replacing this motor, inspect the pump seal and shaft alignment, and follow lock-out/tag-out procedures for electrical safety. Adequate ventilation is required for the ODP enclosure; do not install in fully enclosed spaces without proper airflow.

- Inspect shaft seal and pump housing clearance at motor interface when performing pump maintenance.
- Clean motor ventilation louvers and keep area free of debris to maintain cooling flow.
