SYSTEM PLANNING AND LAYOUT
The NuTone central cleaning system consists of a power unit, PVC tubing and fittings, wall inlets, a flexible hose and various
cleaning attachments.
The power unit is designed to be wall-mounted away from the living area of the home and connected to the living area by means
of permanently installed in-wall tubing, fittings and inlets.
Generally, an installation will require 3 to 4 inlets and 16 to 20 feet of tubing per inlet. It is suggested that a floor plan be used to
more accurately determine the quantity of materials needed.
Use the following examples as an aid in planning the installation in either new or existing construction. You should be able to
adapt the examples shown to your specific home layout.

THE RANCH STYLE HOUSE

Here the power unit is mounted in the

garage. The intake and exhaust tubing,
the only exposed tubing in the installation,
EXHAUST
runs up the garage wall and into the attic.
INLET LINE
The trunk line runs horizontally through the
attic from the power unit to the farthest inlet
location. Branch lines spread throughout
the attic, connecting the trunk line to the
INLETS
inlet tubing. Each inlet tube is threaded
vertically through an inside wall. Located in
hallways and in large rooms, the inlets are

cleaning areas. See figure at right.

THE TWO-STORY HOUSE

ATTIC
TRUNK
LINE
A double-trunk line system is commonly used in two-story

houses. In the installation shown at right, the power unit

is mounted in the basement. The intake tubing runs up

INLET
LINE
the basement wall and connects to the main trunk line,
which runs along the unfinished basement ceiling. Two
first-floor inlets are connected to the basement trunk line
by vertical inlet lines run through interior walls. In the
center of the house, a vertical branch line runs from the
basement trunk line, through stacked closets, up into the
attic. A second trunk line runs across the attic and two
INTAKE
branch lines connect to inlet lines which are dropped

down through upstairs interior walls. See figure at right.

THE SPLIT-LEVEL HOUSE

BRANCH
Like the two-story house, the split level
LINES
VERTICAL
installation commonly calls for a two-level

trunk line. Here, the power unit is located
TRUNK
LINE
in the garage. The intake tubing runs
EXHAUST
exposed up the garage wall and into the
ground level section's attic. Two branch
lines connect this part of the trunk line
to inlet lines which are dropped inside
INLET
interior walls. A vertical branch line runs

to the upstairs attic, where the trunk line

branches into a T-shape. This trunk line

connects to two upstairs inlet lines and LINE INLET
to one inlet line which drops through an
upstairs wall and down into the third-level
utility room to service this entire level. See
