5. Installation Instructions
Important: Before starting installation, ensure the main water supply is turned off. It is recommended to have a qualified plumber perform the installation.
- Prepare the Mounting Hole: Ensure your basin or countertop has a single mounting hole with a diameter of approximately 35mm (φ35mm).
- Insert the Tap: Place the tap body into the mounting hole from above the basin. Ensure the hot and cold water hoses are fed through the hole.
- Secure the Tap: From underneath the basin, slide the rubber gasket, metal washer, and then the mounting nut onto the threaded rod of the tap. Tighten the mounting nut securely using the provided installation tool to prevent movement.
- Connect Water Hoses: Connect the hot water hose (marked 'H' or red) to the hot water supply valve and the cold water hose (marked 'C' or blue) to the cold water supply valve. Ensure all connections are tight to prevent leaks.
- Test for Leaks: Once all connections are secure, slowly turn on the main water supply and check for any leaks around the tap base and hose connections.

- Water Flow: Lift the lever upwards to increase water flow. Push it downwards to decrease or stop the flow.
- Temperature Control: Move the lever to the left for hot water and to the right for cold water. Adjust the position between left and right to achieve the desired water temperature.

7. Maintenance and Care
Proper care will ensure the longevity and appearance of your Ibergrif basin tap:
- Cleaning: Clean the chrome finish regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome. Avoid using harsh chemicals, abrasive sponges, or acidic cleaners, as these can damage the finish.
- Aerator Maintenance: If water flow becomes restricted, the aerator at the end of the spout may need cleaning. Unscrew the aerator, rinse any debris, and reattach it.
- Ceramic Cartridge: The ceramic disc cartridge is designed for long-term, drip-free performance. If leaks occur from the handle, the cartridge may need inspection or replacement by a professional.
8. Troubleshooting
If you encounter issues with your tap, refer to the following common solutions:
- Low Water Flow: Check if the aerator is clogged (see Maintenance section). Ensure water supply valves are fully open.
- Leaks from Spout: Ensure the aerator is securely tightened. If the leak persists, the internal seals or cartridge may require professional inspection.
- Leaks from Handle Base: This often indicates an issue with the ceramic cartridge. Contact a qualified plumber for diagnosis and replacement.
- Difficulty Adjusting Temperature: Verify that both hot and cold water supplies are connected and fully open.
