2. Setup and Installation
The CORNAT LI113 washbasin mixer is designed for deck-mount installation with two holes. It is not suitable for use with electric low-pressure accumulators.
2.1 Components Included
- Washbasin mixer body (brass, chrome-plated)
- Flexible connecting hoses (350mm length, KTW-A tested)
- Aerator (M22 x 1, noise class-tested)
- Retractable plug
- Fittings for installation
Note: A waste valve is not included in the scope of delivery.
2.2 Installation Steps
- Prepare the Installation Area: Ensure the washbasin has two appropriate holes for the mixer and that the water supply lines are accessible and shut off.
- Mount the Mixer Body: Position the mixer body onto the washbasin. The smart shaft-mount design allows for tool-free installation in seconds. Secure the mixer body using the provided fittings from underneath the basin.
- Connect Water Hoses: Attach the two flexible connecting hoses to the mixer body. Connect the other ends of the hoses to the hot and cold water supply lines. Ensure all connections are hand-tightened, then use a wrench for a final quarter-turn to prevent leaks. The 350mm hoses are tested according to current drinking water standards (KTW-A).
- Install Retractable Plug: Follow the instructions provided with the retractable plug for its installation into the washbasin drain.
- Check for Leaks: Slowly turn on the main water supply. Inspect all connections for any signs of leakage. If leaks are detected, tighten the connections further.

3. Operating Instructions
The CORNAT LI113 washbasin mixer features a two-grip design for precise control over water temperature and flow.
- Water Flow Control: Turn the left handle for hot water and the right handle for cold water. Rotate the handles to adjust the water flow from off to full.
- Temperature Adjustment: Mix hot and cold water by adjusting both handles simultaneously to achieve the desired water temperature.
- Swivel Spout: The pipe outlet can be swiveled to direct the water flow as needed, providing flexibility for various washbasin tasks.
- Aerator Function: The integrated, noise-class tested aerator provides a soft, air-enriched water stream, optimizing water usage.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your washbasin mixer.
- Cleaning: Clean the chrome-plated surfaces regularly with a soft cloth and a mild, non-abrasive cleaner. Avoid harsh chemicals, abrasive pads, or acidic cleaners, as these can damage the finish. Rinse thoroughly with water and dry with a soft cloth.
- Aerator Cleaning: If water flow becomes weak or irregular, the aerator may be clogged. Unscrew the aerator from the spout, clean any debris or mineral deposits, and rinse it under running water. Reattach the aerator securely.
- Seal Replacement: The inner upper section with rubber seals is easily replaceable. If you notice persistent dripping or leaks from the handles or spout, these seals may need replacement. Consult a qualified plumber or refer to specific replacement instructions if available.
- Hose Inspection: Periodically inspect the flexible connecting hoses for any signs of wear, kinks, or leaks. Replace damaged hoses immediately to prevent water damage.
5. Troubleshooting
