3. Operating Instructions

The M-Press faucet features a metering mechanism designed to deliver a controlled amount of water per activation.

• Activating Water Flow: Push down the lever-style handle to activate water flow.
• Automatic Shut-off: The faucet is factory preset to automatically shut off after approximately 10 seconds at 80 PSI.
• Adjusting Cycle Time: The metering mechanism is adjustable. An installer can modify the cycle time from 5 to 60 seconds to suit specific requirements. This adjustment also allows compensation for supply line pressures between 20 and 80 PSI.
• Water Temperature: The faucet can deliver either tempered or ambient water, depending on the plumbing configuration.

4. Maintenance

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

• 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.
• Aerator Maintenance: The faucet features a vandal-resistant aerator that limits water discharge to a maximum of 0.5 GPM. Periodically check the aerator for mineral buildup or debris. If water flow is reduced, the aerator may need cleaning or replacement. Consult a professional for removal and cleaning if necessary due to its vandal-resistant design.
• Metering Mechanism: The metering mechanism is self-contained and separated from the potable water supply. No user maintenance is typically required for this component.

5. Troubleshooting

If you encounter issues with your faucet, refer to the following common troubleshooting steps:

• Reduced Water Flow:
  • Check if the water supply valves are fully open.
  • Inspect the aerator for clogs from debris or mineral buildup. Cleaning or replacing the aerator may resolve the issue.
• Water Leaks:
  • Ensure all connections to the supply lines are securely tightened.
  • If leaks persist from the faucet body or handle, contact Moen customer support or a qualified plumber.
• Incorrect Metering Cycle Time:
  • The metering cycle time is adjustable by an installer. If the cycle time is not as desired, a qualified professional may need to adjust the metering mechanism.
