Installing a Moen Two-Handle Kitchen Faucet
To complete the project, you should first gather the tools and all the parts you will need. The basic steps to complete the installation are to prepare the mounting area, install the optional spray attachment, mount the faucet, connect the supply lines, and finally test and flush the faucet.
You should have the following tools available to you before you start: a flashlight, an adjustable wrench, pliers, safety glasses, a basin wrench, plumber's putty, flexible supply lines, Phillips head screwdriver, and a flat-head screwdriver.

Completely clean and dry the faucet mounting area.
For spray models, install the optional spray before installing your faucet. If you do not have a spray attachment, skip to step 6. Place a bead of putty underneath the edge of the spray escutcheon. Install spray escutcheon through the fourth hole in the sink (the right-most hole).
From under the sink, thread the locknut onto the shank of the spray escutcheon and tighten by hand. Make final tightening of locknut with the basin wrench, or by hand.
Feed the spray hose down through the spray escutcheon.
Place deck gasket over faucet shanks. For easy connection of spray hose, bring the spray hose up through the center hole on the deck. Connect the spray hose swivel nut to hose nipple on the faucet before installing faucet onto the sink. Tighten the swivel nut with a wrench being careful to not over tighten.
Most Moen kitchen faucets now feature a Hydrolock connection to attach the side spray hose to the underside of the faucet. The white clips on the adapter need to be in the full open position. Slide the hose into the Hydrolock connector as far as possible then push in the white clip. There will be a distinctive "click" sound. Repeat the process when attaching the Hydrolock connector to the faucet. Be careful to join these fittings as straight as possible.
Non-spray models should now attach the deck gasket. Place faucet in position on the sink with the hot side on the left, and with the deck gasket aligned. Turn the faucet to the side to keep it from tipping over. Be sure the o-ring is in place on the handle insert, thread handle insert into the handle hub. If property installed, lever handles should rotate forward toward spout.
From under the sink, thread plastic mounting nut onto faucet shanks – large side up. Check the faucet position on the sink top, and then hand-tighten.
To connect the supply lines, thread onto the faucet supplies finger tight. Then tighten with a wrench by rotating one half turn.
To avoid damages to your new faucet, do not turn on supply valves until following these instructions. Before using your faucet, make sure that the handles are in the "ON" position. Remove the aerator from the faucet. Open the hot and cold water shut off valves under the sink, and allow the water to run for 15 seconds. Turn the handles to the off position, reinstall the aerator. Your new Moen faucet is now ready for normal use.
