Product Features

- Dimensions: 33" L X 22" W X 9.5" D, designed to fit a minimum 33" cabinet base.

- Installation Versatility: Suitable for both undermount and drop-in installations.
- Optimized Drainage: Rear-positioned drain location maximizes usable bowl and cabinet storage space.
Installation
The BLANCO Diamond Silgranit sink can be installed as either an undermount or a drop-in unit. It is recommended that installation be performed by a qualified professional to ensure proper fit and function.
Required for Installation:
- Installation instructions (included with product)
- Template (included with product)
- Appropriate tools for cutting countertop and securing sink (not included)
- Drain and tailpipes (not included, must be purchased separately)
Ensure your cabinet base is a minimum of 33 inches to accommodate the sink dimensions. Follow the provided template for accurate countertop cutout. Proper sealing and support are crucial for both undermount and drop-in installations to prevent leaks and ensure stability.
Operating Instructions
Your BLANCO Silgranit sink is designed for everyday kitchen tasks. The 60/40 double bowl configuration allows for versatile use, such as washing dishes in one bowl while preparing food in the other. The rear-positioned drain maximizes the usable space within each bowl and provides more storage under the cabinet.
Ensure that the drain type (Lift and Turn) is correctly installed and functioning to prevent water accumulation. Always use appropriate strainers to catch food particles and prevent drain clogs.
Maintenance and Care
Maintaining your BLANCO Silgranit sink is simple due to its durable and non-porous surface. Regular cleaning will preserve its appearance and hygienic properties.
Daily Cleaning:
- After each use, rinse the sink thoroughly with water.
- Wipe the sink dry with a soft cloth to prevent water spots, especially in hard water areas.
- For general cleaning, use a mild dish soap and a soft sponge or cloth.
Deep Cleaning / Stain Removal:
- For tougher stains, a mixture of baking soda and water can be used to create a paste. Apply the paste, let it sit for a few minutes, then gently scrub with a soft brush or sponge and rinse thoroughly.
- Avoid abrasive cleaners, steel wool, or harsh chemicals (e.g., drain cleaners containing sulfuric acid, paint removers, oven cleaners) as these can damage the Silgranit surface.
- The Hygienic+Plus surface actively resists bacteria, but regular cleaning is still recommended for optimal hygiene.
Troubleshooting
While BLANCO Silgranit sinks are highly durable, occasional issues may arise. Here are some common concerns and general solutions:
Water Spots/Mineral Deposits:
If you notice white spots or mineral deposits, especially in hard water areas, these are typically calcium buildup. Use a solution of equal parts white vinegar and water, or a specialized descaling agent. Apply, let sit for 15-30 minutes, then scrub gently and rinse thoroughly.
Scuff Marks:
Although highly scratch-resistant, heavy metal objects can sometimes leave superficial scuff marks. These are usually metal residue on the sink surface, not actual scratches to the Silgranit. Use a non-abrasive cleaner like Bar Keepers Friend or a specialized Silgranit cleaner with a soft cloth to remove these marks.
Drainage Issues:
If water is draining slowly, check the sink strainer for accumulated food particles. For persistent clogs, use a plunger or a plumber's snake. Avoid chemical drain cleaners that contain harsh acids, as they can damage plumbing and potentially the sink surface over time.
