Install the Spout (cont.)
Thread the spout onto the mixer valve until the spout is fully
seated. If necessary, unthread the spout for alignment.
Slide the escutcheon away from the finished wall to access the
setscrew holes.
Using a 3/32" hex wrench, tighten the three setscrews in the wall
flange until the setscrews contact the spout. Fully tighten the
setscrews.
Slide the escutcheon back against the finished wall and onto the
wall flange.
With the escutcheon setscrew hole at the 6 o'clock position, use a
5/64" hex wrench to secure the escutcheon with a setscrew.
