Shut off the water. Remove the old faucet supply lines (Image 1), which will expose the holes in the sink.
Use a pair of snips or scissors to cut the old plastic sprayer line from the faucet.
Use a basin wrench to loosen up both the hot and cold water supply lines (Image 2). Unscrew the lines from the faucet. Have a bucket handy to catch the water.
Keep a bucket and rag close by to clean up water left in the lines.
Remove the soap container and locking nut from the soap dispenser. Apply plumber's putty around the bottom edges, and then insert it into the farthest hole from the center.
Apply a generous amount of plumber's putty to the underside of the escutcheon cover, and then firmly place it over the three center holes on the sink.
Fit the faucet through the hole in the escutcheon cover, and then position the faucet so the handles face in the proper direction -- usually to the user's right.
Partially thread two screws into the threaded ring until they protrude from the backside of the threaded ring.
Slide the fiber washer, metal washer and ring over the supply lines. Screw them onto the threaded shank until the ring is about 1/4 inch away from the sink bottom and the screws are to the front and back. Tighten everything down.
Thread the plastic locking nut onto the shank of the soap dispenser, and then use the basin wrench to tighten it down. Screw the soap container over the shank, ensuring that it's tight.
Slide the weight onto the spray hose, and then connect the two ends making sure they are locked into place.
Position the hot and cold supply lines so they will not interfere with the other hoses, and then connect them to the existing supply lines and tighten.
