Installation Instructions

Fill the recess under the valve and spout escutcheons with plumber's putty (not included). Place spout with es- cutcheon and adapter in place down through the center hole. Put washer over spout shank. Screw on mounting nut and make hand-tight. Turn mounting nuts on valve bodies all the way down, for basin clearance, and drop on mounting washers.

With the valve bodies and supply tubing assembled under the sink, slide the bodies up through the holes. Screw top mounting nuts down until top of valve bodies are 3/8" to 7/16" from top of deck. (See illustration). Place a

3/8" bead of plumber's putty (not supplied) around the underside of handle escutcheons. Screw the escutch- eons onto valve bodies and hand-tighten them until they bottom out. Screw the mounting nuts and washers up against the bottom of the basin and hand-tighten. Hold the valve bodies from turning by using another wrench on valve body flats. Install supply tubing to spout "T". Hold back spout tee with wrench when tightening sup- ply tube.

Test the lift rod to make sure it operates freely. NOTE: If lift rod binds against spout union tee, carefully bend spout tube slightly outward to clear lift rod.
