- Filling Basins: Use the appropriate faucets (not included) to fill the basins with water as needed for washing, rinsing, or soaking.

- Hygiene: Always maintain high hygiene standards. Clean the basins and surrounding areas regularly, especially after use with food products.
6. Maintenance
Proper maintenance will extend the lifespan of your stainless steel sink and ensure continued hygienic operation.
- Daily Cleaning: After each use, clean the sink with warm water and a mild detergent. Rinse thoroughly and dry with a soft cloth to prevent water spots.
- Avoid Abrasives: Do not use abrasive cleaners, steel wool, or harsh chemicals (e.g., bleach, strong acids) as these can scratch or damage the stainless steel surface.
- Stubborn Stains: For stubborn stains, use a specialized stainless steel cleaner and follow the product instructions. Always rub in the direction of the grain.
- Drain Maintenance: Periodically check the drains for blockages and clear any food debris. Ensure the overflow pipe is also clear.
- Structural Check: Regularly inspect the legs and shelf for stability. Tighten any loose fasteners as needed.

7. Troubleshooting
This section addresses common issues you might encounter with your sink unit.
- Water Leaks:
Possible Cause: Loose plumbing connections.
