An overview of all included components for installation, including the faucet body, mounting hardware (gaskets, nut, washer), and braided hot and cold water supply hoses.
Installation Steps:
- Prepare the Basin: Ensure the mounting hole in your basin is approximately 35mm in diameter. Clean the area around the hole.
- Insert the Faucet: Place the faucet body into the mounting hole from above the basin. Ensure the base gasket is properly seated.
- Secure the Faucet: From underneath the basin, slide the rubber washer, metal washer, and mounting nut onto the threaded shank of the faucet.
- Tighten the Mounting Nut: Hand-tighten the mounting nut, then use a screwdriver to firmly secure the screws on the mounting nut, ensuring the faucet is stable and centered.
- Connect Water Supply Lines: Attach the hot (marked 'H' or red) and cold (marked 'C' or blue) water supply hoses to the corresponding inlets on the faucet. Use sealant tape on the threads for a watertight seal.
- Connect to Water Supply: Connect the other ends of the supply hoses to your hot and cold water shut-off valves. Tighten securely with an adjustable wrench.
- Test for Leaks: Slowly turn on the main water supply and check all connections for leaks. If leaks occur, tighten the connections slightly.

- Water Temperature: 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 your desired temperature.
Maintenance
Cleaning the Faucet:
The stainless steel surface of your Ibergrif faucet is designed for easy cleaning and maintenance. To preserve its finish:
- Clean regularly with a soft cloth and mild soap or a non-abrasive cleaner.
- Avoid using abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the finish.
- Rinse thoroughly with clean water after cleaning and dry with a soft cloth to prevent water spots.
Aerator Cleaning:
Over time, mineral deposits can accumulate in the aerator, affecting water flow. The Neoperl aerator can be easily removed for cleaning.

- Unscrew the aerator from the end of the spout by hand.
- Rinse the aerator under running water to remove any loose debris.
- For stubborn deposits, soak the aerator in a solution of equal parts white vinegar and water for 15-30 minutes.
- Brush away any remaining deposits with a small brush (e.g., an old toothbrush).
- Rinse thoroughly and screw the aerator back into the spout.
Ceramic Cartridge:
The faucet is equipped with a superior ceramic disc cartridge, designed for long-lasting, drip-free performance, tested for up to 500,000 cycles. If you experience persistent drips or issues with temperature control, the cartridge may need replacement. Contact customer support for assistance.
