Important Notes:
- The integrated Silver Guard feature helps protect the disposer from falling metal items, such as silverware, by magnetically holding them in place.
- Avoid disposing of large amounts of fibrous materials (e.g., corn husks, artichokes), grease, oil, hot liquids, or non-food items.
- The disposer is safe to use with septic tanks.
