Setup and Installation
Before installation, ensure all necessary components are present and that you have the required tools. This faucet is designed for installation through either a 1-hole or 3-hole sink configuration, utilizing the included optional deckplate.
Required Tools (Not Included):
- Adjustable Wrench
- Phillips Screwdriver
- Plumber's Putty or Silicone Sealant
- Safety Glasses
Installation Steps:
- Turn Off Water Supply: Locate the main water supply valves for your bathroom sink and turn them off. Open the existing faucet to drain any remaining water.
- Remove Old Faucet: Disconnect the water supply lines from the old faucet and remove any mounting hardware. Carefully lift and remove the old faucet from the sink. Clean the sink surface thoroughly.
- Prepare for Installation: If installing on a 3-hole sink, place the optional deckplate over the holes. Apply a thin bead of plumber's putty or silicone sealant around the base of the new faucet.
- Install Faucet: Insert the faucet body through the hole(s) in the sink or deckplate. From underneath the sink, secure the faucet with the provided mounting hardware, ensuring it is centered and tightened securely.
- Connect Water Supply Lines: Connect the hot and cold water supply lines from the faucet to the corresponding water supply valves. Hand-tighten, then use an adjustable wrench for a final quarter-turn. Do not overtighten.
- Install Drain Assembly: Follow the separate instructions provided with the included drain assembly for proper installation into your sink.
- Test for Leaks: Slowly turn on the main water supply. Check all connections for leaks. If leaks are detected, gently tighten the connections until they stop. Operate the faucet to ensure proper hot and cold water flow.

Operating Instructions
The Moen Halle faucet features a single lever handle for controlling both water temperature and flow.
- Turning On/Off: Lift the handle upwards to turn on the water. Push the handle downwards to turn off the water.
- Adjusting Water Flow: The further the handle is lifted, the greater the water flow.
- Adjusting Water Temperature: Move the handle to the left for hot water and to the right for cold water. The position between left and right will provide mixed temperatures.
The aerated flow is designed for daily bathroom tasks such as washing hands and brushing teeth, providing a consistent and splash-free stream.
Care and Maintenance
Proper care will help maintain the finish and performance of your Moen Halle faucet.
- Cleaning the Finish: Clean the Matte Black finish with a soft, damp cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish and void your warranty.
- Aerator Maintenance: If water flow decreases or becomes irregular, the aerator may be clogged. Unscrew the aerator from the faucet spout, clean any debris or mineral deposits, and then reattach it.
- Leak Checks: Periodically inspect all connections for any signs of leaks. Tighten connections gently if necessary.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Clogged aerator; partially closed supply valve. | Clean aerator (see Maintenance); ensure supply valves are fully open. |
