Installing a Moen Harlon Kitchen Faucet
The instructions for installing a Moen kitchen faucet, as with any faucet, will vary slightly based on the design of the model. The steps here show how to remove an old faucet and install a new Moen Harlon series faucet. The installation is similar to that of other Moen kitchen faucet models with a single handle. This faucet includes pre-attached flexible water supply lines with 3/8-inch compression (screw-on) fittings. If your shutoff valves under the sink are 1/2-inch instead of 3/8-inch,... connect the supply lines with 3/8-to-1/2-inch compression adapters.

- New Moen Harlon Single-Handle Faucet
- Tongue-and-groove pairs (two pairs)
- Basin wrench (optional)
- Plumber's tape (optional)
- 3/8-to-1/2-inch compression adapters (two; as needed)

Disconnect the Water Supply
Shut off the water to the old faucet by closing the shutoff valves on the hot and cold water supply pipes under the sink; turn the shutoff valve handles clockwise until they stop.
Disconnect the faucet's flexible supply lines from the shutoff valves, using two pairs of pliers. Hold the valve body in place with one pair of pliers, and loosen the compress nut on the supply line with the other pliers.Continue to 3 of 7 below.

Remove the Old Faucet
Remove the old faucet by loosening the mounting nut (or nuts) on the underside of the sink. It helps to have a basin wrench to work in this tight space, but otherwise you can use tongue-and-groove pliers. Once the nut is loosened, unthread it all the way by hand, then pull the faucet up and away from the top of the sink.
Clean the top of the sink to remove any stains left at the base of the faucet. Chances are the footprint of the new faucet will be different and the more you clean the top of the... sink the better it will look.Continue to 4 of 7 below.

Install the Faucet Body
Install the deck gasket onto the new faucet by fitting it over the flexible supply lines and sliding it up into the faucet body. Feed the supply lines through the sink hole, and center the faucet body over the hole. Position the faucet where you want it and make sure it fits well before going below the sink to secure it.
Note: If you are using the optional escutcheon kit to cover unused sink holes (for three- and four-hole sinks), position the plastic spacer and escutcheon onto the sink before... installing the faucet body.Continue to 5 of 7 below.

Secure the Faucet
Place the rectangular support plate into position on the underside of the sink, fitting it over the supply lines and the threaded tailpiece of the faucet body and up against the sink. Place the round plate under the rectangular plate, then thread the brass mounting nut onto the faucet tailpiece. The tailpiece is also the housing for the sprayer hose.
Use the installation tool provided with the faucet to tighten the mounting nut most of the way. Check the position of the faucet above the sink,... then finish tightening the mounting nut until the faucet is tight enough that it won't move.Continue to 6 of 7 below.

Install the Faucet Spray Hose
Continue to 7 of 7 below.
- Screw the spray hose housing nut onto the end of the faucet tailpiece.
- Attach the spray hose to the faucet spray wand by screwing it on.
- Feed the other end of the spray hose into the faucet spout until the end comes out under the sink.
- Remove the white cap from the end of the spray hose.
- Connect the spray hose to the body of the faucet by pushing the hose into position and using the white clip to hold it in place.
- Attach the weight onto the spray hose, positioning it near the white tape on the hose.... The weight must move up and down freely with the spray hose; test it by moving the spray wand in and out of the faucet spout. The hose should move easily without hitting anything under the sink.

Connect the Water Supply Lines
Connect the hot and cold supply lines of the faucet to the shutoff valves on the hot and cold water supply pipes, using the compression fittings. Thread the compression nut on each line onto the valve and tighten the nut with two pairs of pliers—one to hold the valve body and one to tighten the nut (if desired, apply plumber's tape to the valve threads before connecting the lines).
Make sure flexible lines won't interfere with the spray hose and are not kinked. Turn the water back on by... opening the shutoff valves all the way (turning counterclockwise). Check the faucet for proper operation and confirm there are no leaks in the flexible lines or the spray hose.
