5. Operating Instructions
5.1 Using the Workstation Features
The workstation design allows for versatile use of the sink space. The overhanging lips on the front and back serve as a track for sliding the included accessories.
- Cutting Board: Place the wood cutting board on the tracks to create an integrated food preparation area over the sink.
- Colander: Slide the stainless steel colander onto the tracks for rinsing fruits and vegetables, allowing water to drain directly into the sink.
- Roll-up Drying Rack: Position the roll-up rack over the sink for air-drying dishes, pots, or pans. It can be easily rolled up and stored when not in use.
- Dish Grid: Place the dish grid at the bottom of the sink to protect the surface from scratches and allow water to drain underneath dishes.

The sink features an X-shape flow line and engineered drain grooves on the bottom to facilitate efficient water drainage and prevent pooling. The deep drain basket helps to catch food debris and prevent clogging of the drain pipe.

6. Maintenance and Care
6.1 Cleaning the Sink
- For daily cleaning, wipe the sink with a soft cloth and mild dish soap.
- Rinse thoroughly with water and wipe dry to prevent water spots.
- Avoid abrasive cleaners, steel wool, or harsh chemicals, as these can damage the stainless steel finish.
- For stubborn stains, use a non-abrasive stainless steel cleaner and follow the product instructions.
6.2 Preventing Scratches and Stains
- Use the included dish grid to protect the bottom of the sink from heavy pots and pans.
- Avoid dropping sharp or heavy objects directly onto the sink surface.
- Rinse the sink immediately after use to remove food particles and acidic liquids that could cause staining.
6.3 Sound Dampening and Condensation Protection
The sink is equipped with sound-proof rubber pads on the bottom to minimize noise from dishes and water flow. An anti-condensation spray undercoating is applied to prevent moisture buildup, protecting your cabinets from potential water damage.
