Safety Instructions

Setup and Installation
The Franke Sirius 2.0 S2D 611-78 is designed for inset installation. Follow these steps for proper setup:
- Prepare the Worktop: Ensure the worktop is clean, dry, and level. Mark the cutout area according to the provided template (not included in this manual, refer to packaging).
- Cut the Opening: Carefully cut the opening in the worktop using appropriate tools. Ensure the edges are smooth and free of debris.
- Apply Sealant: Apply a bead of silicone sealant around the edge of the cutout opening to create a watertight seal.
- Position the Sink: Carefully lower the sink into the cutout opening, ensuring it is properly aligned. Press down firmly to engage the sealant.
- Secure the Sink: Use the provided fixing clips (if applicable) to secure the sink to the underside of the worktop. Tighten the clips evenly to ensure a snug fit.
- Connect Plumbing: Install the waste kit and connect the plumbing according to local regulations. Ensure all connections are watertight.
- Install Faucet: Mount the faucet onto the sink or worktop (if pre-drilled) and connect the water supply lines.
- Test for Leaks: Turn on the water supply and check all connections for leaks. Rectify any leaks immediately.

Maintenance and Care
To maintain the appearance and performance of your Tectonite sink, follow these care guidelines:
- Daily Cleaning: Clean the sink regularly with warm soapy water and a soft cloth or sponge. Rinse thoroughly and dry to prevent water spots.
- Stubborn Stains: For more stubborn stains, use a non-abrasive cream cleaner specifically designed for composite sinks. Apply with a soft cloth, rub gently, then rinse and dry.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, steel wool, scouring pads, or strong chemical agents (e.g., drain cleaners, paint removers, oven cleaners) as these can damage the Tectonite surface.
- Heat Resistance: While Tectonite is highly heat resistant, avoid placing extremely hot pans directly onto the surface. Always use a trivet or heat protection mat.
- Prevent Scratches: Although Tectonite is durable, avoid dragging heavy or sharp objects across the surface to prevent scratches.

Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
