Instructions / Assembly

Use an awl or icepick to punch pilot holes where you
marked the two hole locations. Now, drill two 3⁄8”
diameter holes, using the pilot holes as the centers.
Locate and drill these holes exactly as marked with
the template.
Also drill four pilot holes in the four corners of the marked
area. Make sure these holes are located inside the
marked line. Then, using a utility knife, score along the
inside of the marked line. For plaster walls, score the
plaster deeply, being careful to stay inside the marked line.
Next, use a keyhole
saw or a sabersaw
to make the cutout.
Again, be extremely
careful to cut along
the inside of the
marked line.
Attaching the Inlet Mounting Plate
Reach through the inlet hole and locate the inlet tubing.
Raise it up inside the wall until you locate the inlet
tubing. If the inlet is connected from the basement, have
a helper insert the inlet tubing into the access hole until
you can see the flexible tubing. Then, pull the flexible tub-
ing through the inlet hole and remove the low
voltage wiring from inside the tube. If the end of the
flexible tubing is not even, trim it so that it is exactly even.
Now, remove the nail flange (used for new construction)
from the inlet mounting plate. Use pliers to bend this flange
along the scored lines until you can break it off.
Apply cement to both the
inside of the flexible tubing
and to the outside of the
mounting plate’s tube ring.
Insert the mounting plate’s
tube ring in the flexible
tubing and twisting the
pieces as you join them to
spread the cement, and
align the mounting plate in
a vertical position.
