Important Notes
- This is an ultra-fine filter basket intended for fine debris capture; it may load up faster in heavy leaf conditions than coarse filters.
- For best results, rinse the basket after each cleaning cycle (or more often during dusty or high-debris conditions).
- Confirm your cleaner uses the basket assembly style compatible with part 9991460-R1.
Use & Care Notes
- Remove the basket from the cleaner and rinse thoroughly with a hose after use.
- Do not allow debris to dry and harden inside the filter media.
- Inspect the basket frame, latches, and filter media regularly for cracks or wear.
- Reinstall the basket securely before operating the cleaner.
- Keep a spare basket on hand for faster swap-and-go maintenance.

Maintenance Tips
- Rinse the basket immediately after each cleaning cycle to prevent fine debris from packing into the media.
- Rotate between two baskets during peak season to reduce downtime.
- Inspect for debris bypass if you notice dirt returning to the pool, and confirm the basket is seated properly.
- Replace the basket if the frame cracks, latches fail, or filtration performance declines.
