4. Setup and Installation

The Cornat FAB535 faucet is designed for single-hole deck mount installation. Ensure you have all included mounting accessories before starting.

4.1 Pre-Installation Checks

• Verify that your water heating system uses an electric low-pressure accumulator. This faucet is not compatible with high-pressure systems.
• Confirm that the mounting surface is clean and stable.
• Gather necessary tools (e.g., adjustable wrench, screwdriver, sealant tape).

4.2 Installation Steps

1. Shut off Water Supply: Locate and turn off the main water supply to your sink.
2. Prepare Mounting Hole: Ensure the sink's mounting hole is clean and appropriately sized for a single-hole installation.
3. Install Faucet: Insert the faucet base into the mounting hole. From underneath the sink, secure the faucet using the provided mounting accessories (washer, nut). Tighten firmly but do not overtighten.
4. Connect Water Lines: Attach the flexible connection hoses (350 mm length, KTW-A standard) to the corresponding hot and cold water supply valves. Ensure a watertight seal using sealant tape if necessary.
5. Connect Spray Hose: Connect the extendable spray hose (1200 mm length) to the designated port on the faucet body.
6. Check for Leaks: Slowly turn on the main water supply and check all connections for any signs of leakage. Tighten connections as needed.
7. Test Operation: Operate the faucet to ensure proper water flow and temperature control. Test the extendable spray head and its switch-over function.

5. Operating Instructions

The Cornat FAB535 features a single lever handle for controlling water flow and temperature, a swivel spout, and an extendable spray head.

• Water Flow and Temperature: Lift the single lever handle to increase water flow. Move the handle left for hot water and right for cold water.
• Swivel Spout: The faucet's spout can be rotated to direct water flow as needed within the sink area.
• Extendable Spray Head: Pull the spray head from the spout to extend it for greater reach. The spray head includes a switch-over function (2.1 inch) to change between different spray patterns. Push the spray head back into the spout when finished.

6. Maintenance

Regular cleaning and maintenance will ensure the longevity and optimal performance of your faucet.

• Cleaning: Clean the chrome-plated surfaces with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome finishes. Avoid harsh chemicals, abrasive pads, or acidic cleaners, as these can damage the finish.
• Cartridge Replacement: The faucet features an easily replaceable, KTW approved cartridge with durable ceramic sealing discs. If you experience persistent drips or difficulty controlling water temperature, the cartridge may need replacement. Consult a professional if unsure.
• Sieve Flow Regulator: The M 24 x 1 sieve flow regulator (Made in Germany) can be removed and cleaned periodically to maintain optimal water flow.

7. Troubleshooting

If you encounter issues with your faucet, refer to the following common problems and solutions:

• Low Water Flow: Check if the sieve flow regulator is clogged. Clean or replace it if necessary. Ensure water supply valves are fully open.
• Leaking from Spout: This often indicates a worn-out cartridge. The KTW approved ceramic cartridge is replaceable.
• Leaking from Connections: Ensure all hose connections are securely tightened. If leaks persist, check the condition of washers and seals.
• No Hot/Cold Water: Verify that the hot/cold water supply is active and that the low-pressure accumulator is functioning correctly.

For problems not listed here or if solutions do not resolve the issue, contact customer support or a qualified plumber.
