Operating Instructions
The Moen Chateau faucet set is designed for ease of use, providing precise control over water temperature and flow.
Temperature and Flow Control:
- Turn On/Off: Lift the single lever handle to turn on the water. Push down to turn off.
- Adjust Temperature: Rotate the handle counter-clockwise for hotter water and clockwise for colder water. The Posi-Temp valve ensures a consistent temperature by compensating for pressure fluctuations in the water lines.
- Adjust Flow: The flow rate is controlled by how far the handle is lifted.
Tub Spout Diverter:
- To divert water from the tub spout to the showerhead, pull up the knob on the tub spout.
- To return water flow to the tub spout, push the knob down.
Maintenance
Regular maintenance will help preserve the finish and functionality of your Moen Chateau faucet set.
Cleaning the Finish:
- Clean the chrome finish with a soft, damp cloth and mild soap.
- Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Rinse thoroughly after cleaning and dry with a soft cloth to prevent water spots.
