4.1. Required Tools (Not Included)

- Plumber's tape (PTFE tape)
- Basin wrench (optional, for tight spaces)
4.2. Installation Steps
- Prepare the Installation Area: Turn off the main water supply. Clear the area under the sink. Remove any existing faucet if applicable.
- Mount the Faucet: Insert the faucet body through the single mounting hole on the sink or countertop. Ensure any rubber gaskets are correctly positioned between the faucet base and the sink surface to prevent leaks.
- Secure the Faucet: From underneath the sink, slide the metal washer and mounting nut onto the threaded shank of the faucet. Tighten the nut securely with an adjustable wrench or basin wrench. Do not overtighten.
- Connect Water Supply Lines: Attach the flexible hot and cold water supply lines to the corresponding inlets on the faucet. Use plumber's tape on the threads for a watertight seal. Connect the other ends of the supply lines to the hot and cold water shut-off valves. Tighten connections firmly but avoid overtightening.
- Check for Leaks: Slowly turn on the main water supply. Check all connections for any signs of leaks. If leaks are present, tighten the connections slightly until the leak stops.
- Test Operation: Turn on the faucet and allow water to run for a few minutes to flush out any debris from the lines. Check for proper hot and cold water flow and temperature control.

5. Operating Instructions
The CORNAT LI91 Lisa Stand Faucet features a single lever handle for controlling both water flow and temperature.
- Water Flow: Lift the lever handle upwards to increase water flow. Push it downwards to decrease or turn off the water.
- Temperature Control: Move the lever handle 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.
- Swiveling Spout: The spout can be swiveled from side to side to direct water flow as needed.
6. Maintenance
Regular maintenance will help preserve the appearance and functionality of your CORNAT LI91 Lisa Stand Faucet.
- Cleaning: Clean the faucet regularly with a soft cloth and mild soap and water. Rinse thoroughly and dry with a soft cloth to prevent water spots.
- Avoid Harsh Cleaners: Do not use abrasive cleaners, scouring pads, ammonia-based cleaners, or any cleaners containing bleach or alcohol, as these can damage the chrome finish.
- Aerator Maintenance: If water flow becomes restricted, the aerator at the tip of the spout may be clogged. Unscrew the aerator, clean any debris, and rinse it before reattaching.
- Leak Checks: Periodically check all connections for any signs of leaks and tighten if necessary.
