Installation Steps:

- Apply a thin bead of plumber's putty or silicone sealant around the base of the faucet body.
- Insert the faucet body into the mounting hole.
- From underneath the sink, secure the faucet using the provided mounting washer and nut. Hand-tighten first, then use an adjustable wrench to snug it securely. Do not overtighten.
- Connect Water Line:
- Connect the cold water supply line from your filtration system to the inlet on the bottom of the faucet. Ensure a watertight seal using a wrench.

- Slowly turn on the main cold water supply.
- Inspect all connections for leaks. If leaks are present, gently tighten the connections until they stop.
Operating Instructions
The Waterstone 1455C-MB faucet features a single lever handle for simple operation.
- To Turn On: Lift the lever handle upwards. The further you lift, the greater the water flow.
- To Turn Off: Push the lever handle downwards to its original position.
- Spout Swivel: The U-spout can swivel 360 degrees for convenience.
Maintenance and Care
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 Matte Black finish.
- Rinse thoroughly after cleaning and dry with a soft cloth to prevent water spots.
Aerator Maintenance:
- If water flow decreases, the aerator may be clogged. Unscrew the aerator from the tip of the spout.
- Rinse any debris from the aerator screen under running water.
- Reattach the aerator, ensuring it is securely tightened.
Troubleshooting
| Problem | Possible Cause | Solution |
