Installation Steps:
- Insert the Faucet: Place the main faucet body and handles into the corresponding holes on your sink deck. Ensure they are properly aligned.
- Screw the Plastic Nut: From underneath the sink, secure the faucet and handles by screwing on the plastic nuts provided. Hand-tighten initially, then use a wrench for a snug fit, but do not overtighten.
- Connect the Snap-on Connector: Attach the snap-on connector of the supply lines to the faucet's inlets. Ensure a secure, leak-free connection.
- Connect the Angle Valves: Connect the other end of the supply lines to your hot and cold water angle valves. The 3/8" female compression thread connects directly. If your angle valves are 1/2", use the provided 1/2" adapters with their matching rubber gaskets for a secure fit.

5. Operating Instructions

6. Maintenance
- Cleaning: Clean the faucet regularly with a soft cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Check for Leaks: Periodically inspect all connections for any signs of leaks. Tighten connections if necessary, but do not overtighten.
- Filter Maintenance: The 3/8" connector features a built-in filter to remove impurities. If water flow decreases, the filter may need cleaning. Turn off the water supply, disconnect the supply line, and clean the filter screen.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leakage | Loose connections, damaged washer, improper installation of supply lines. | Ensure all connections are tight. Check rubber washers for proper seating and replace if damaged. Verify supply lines are not kinked or improperly installed. |
| Low Water Flow | Clogged filter in supply line connector, kinked supply line, low water pressure from main supply. | Clean the built-in filter in the 3/8" connector. Check supply lines for kinks and straighten if found. Consult local water utility if main pressure is consistently low. |
| Faucet Handles Stiff | Mineral buildup, internal component issue. | Flush the system. If problem persists, contact customer support. |
