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 tubing
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.
Hold the assembly in a place for a few minutes as the cement
sets; allow five minutes for the cement to completely dry.
Now, strip the ends of the two low-voltage wires, and then
connect the wires to the screw terminals on the back of the
inlet cover. Make sure the wires are tightly secured under the
terminal screws. When the wiring is complete, assemble the
inlet cover to the tube guard and mounting plate. Insert the
top screw through the entire inlet assembly until the screw
engages the mounting plate.
Completing the Inlet Assembly
Once you have attached the
mounting plate to the
flexible tubing, pull the
low-voltage wire through the
top wiring hole in the
mounting plate.
