Cut a piece of low voltage
wire which is long enough
for the complete inlet line,
allowing 6” for connections
to the inlet wall plate.
Secure the wire to the
tubing with electrical tape.
Tuck the 6” wire lead inside
the flexible tubing so that
it will not snag inside the
wall.
If space permits, you
can assemble the entire
inlet line by joining two
sections of tubing with
a stop coupling before
dropping the assembly
into the access hole.
(Remember to only glue
the outside of the tubing
when joining two pieces of
PVC tubing.) Oftentimes,
tight attic spaces require
you to begin your drop and
then join the second section of tubing. Of course, the order of
assembly, and the length of tubing required depend on your
attic space and your wall height.
Whatever the case, insert
the completed inlet line
into the access hole and
thread it down inside the
wall. The inlet line should
be long enough so that it
extends above the joists
in the attic; at this height, it
can be easily connected to
the branch and truck lines.
When cutting the inlet
tubing to length, remember
that your inlet will be placed at 18” above the floor.
For a basement installation,
assemble the tubing to
the inlet flexible tubing in
the same way and insert
it into the access hole.
A basement inlet line
is necessarily shorter
because it must only reach
18” from the floor to the
inlet. Most of the time,
basement inlet lines are
more easily installed by
two people after the inlet
hole has been cut in the
interior wall. See “Wall Inlet
Installation.”
Complete all your inlet lines, and then proceed to your inlet
installations.
WALL INLET INSTALLATION
The wall inlet design allows you to work outside the wall—
where assembly is easy and all the parts you need are
accessible. First, you make a cutout into the wall and locate the
flexible tubing attached to the inlet line which you previously
threaded into the wall. Then, you attach the flexible tubing to
the inlet mounting plate, assemble the other inlet parts, and
make the wiring connections. You place the inlet assembly into
the wall cutout, sandwiching the wall between the inner and
outer parts, and secure the inlet tightly to the wall with two
screws.
Assemble and install the wall inlet as shown in the illustrations
and as explained in the next few pages. Be careful and patient
as you make your first cutout and install your first inlet by
following the procedure step by step—the other inlets will be
easy to install in very little time.

The wall inlet should be
located 18” on-center from
the floor and directly in line
with the attic or basement
inlet tubing hole you have
already drilled in the wall
plate or header. the wall
inlet cutout must be exactly

is crucial that you make an
accurate cutout, and we
have supplied a template
to help you.
