Setup and Installation
The Moen Lindor 84505BL faucet is designed for either 1-hole or 3-hole deck mount installations. For 3-hole installations, use the included deck plate.
Step 1: Prepare the Sink Area
Turn off the water supply at the shut-off valves under the sink or at the main water supply. Clear the area under the sink for access.
Step 2: Install the Faucet
Insert the faucet body through the hole(s) in the sink or countertop. If using the deck plate, ensure it is properly seated before placing the faucet. Secure the faucet from underneath the sink using the provided mounting hardware (washer and nut).

Step 3: Connect Water Supply Lines
Connect the hot and cold water supply lines from the faucet to the corresponding shut-off valves. Hand-tighten first, then use a wrench for a quarter turn. Do not overtighten.
Step 4: Install the Drain Assembly
Follow the instructions provided with the pop-up drain assembly to install it into the sink drain hole. Ensure a watertight seal using plumber's putty or silicone sealant as directed.
Step 5: Test for Leaks
Once all connections are secure, slowly turn on the main water supply. Check all connections for leaks. Run the faucet for a few minutes to flush out any debris and check for proper operation.
Operating Instructions
The Moen Lindor 84505BL features a single handle for controlling both water flow and temperature.
- Water Flow: Lift the handle upwards to turn on the water and increase flow. Push the handle downwards to decrease flow and turn off the water.
- Temperature Control: Move the handle to the left for hot water and to the right for cold water. Adjust the handle position between left and right to achieve the desired water temperature.
- The faucet provides an aerated flow, which is suitable for daily bathroom tasks such as washing hands and brushing teeth.

Maintenance
Proper care will help maintain the finish and performance of your Moen faucet.
- Cleaning the Finish: Clean the matte black finish regularly with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or polishes, as these can damage the finish. For matte black finishes, daily cleaning may be required to remove water spots, soap residue, and toothpaste.
- Aerator Maintenance: If water flow decreases, the aerator may be clogged. Unscrew the aerator from the spout, clean any debris, and rinse thoroughly before reattaching.
- Handle Material: The handle is made of plastic. Clean gently with a soft cloth.
