5. Setup and Installation
The Pyramis ET33 Fork sink is designed for inset installation into a countertop. It is suitable for cabinets from 45 cm wide.

- Measure the available space to confirm compatibility with the sink dimensions.
- Mark the cutout area on the countertop using the provided template or the dimensions below.

Figure 5.2: Recommended Countertop Cutout Dimensions (W x D: 840mm x 415mm).
5.2. Installation Steps
- Cut the Countertop: Carefully cut the opening in the countertop according to the marked dimensions. Ensure clean edges.
- Apply Seal: Apply the polyurethane foam seal around the edge of the sink cutout on the underside of the sink flange. This creates a watertight seal.
- Position Sink: Carefully lower the sink into the cutout opening, ensuring it is properly aligned.
- Secure Sink: From underneath the countertop, attach the provided installation clips and screws to secure the sink firmly in place. Tighten evenly to ensure a snug fit.
- Install Faucet and Drain: Install your chosen faucet and connect the drain assembly, including the large strainer plug, according to their respective manufacturer's instructions.
- Connect Plumbing: Connect the water supply lines to the faucet and the drain pipe to the household drainage system. Ensure all connections are tight and leak-free.
- Test for Leaks: Turn on the water supply and check all connections for any leaks. Address any leaks immediately.
6. Operating Instructions
The Pyramis ET33 Fork sink operates like any standard kitchen sink. Use the faucet to control water flow and temperature. The large strainer plug in the drain prevents food particles from entering the plumbing system. To drain water, simply open the strainer plug. To retain water in the bowl, close the strainer plug.
7. Maintenance and Care
Proper care will ensure the longevity and appearance of your stainless steel sink.
- Daily Cleaning: After each use, rinse the sink thoroughly with water to remove food particles and soap residue. Wipe with a dry, soft cloth to prevent water spots and maintain shine.
- Regular Cleaning: For more thorough cleaning, use a mild dish soap or a specialized stainless steel cleaner with a soft sponge or cloth. Always rub in the direction of the grain of the stainless steel.
- Avoid Abrasives: Do not use abrasive cleaners, steel wool, wire brushes, or harsh chemicals (e.g., bleach, strong acids) as these can scratch the surface or cause discoloration.
- Prevent Stains: Avoid leaving acidic foods (e.g., citrus, tomatoes) or corrosive substances in contact with the sink surface for extended periods. Rinse immediately if contact occurs.
- Hard Water Spots: For hard water spots, use a solution of vinegar and water, then rinse and dry thoroughly.
8. Troubleshooting
- Slow Drainage: Check the strainer plug for blockages. If clear, inspect the P-trap and drain pipes for obstructions.
- Water Leaks: Re-check all plumbing connections for tightness. Ensure the polyurethane foam seal is properly seated around the sink's edge.
- Water Spots/Dull Finish: Ensure the sink is dried thoroughly after each use. Use a stainless steel cleaner to restore shine.
- Scratches: Stainless steel can scratch. Minor scratches can sometimes be blended with specialized stainless steel scratch removal kits, following the grain of the steel.
