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.
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, runs up
the garage wall and into the attic.
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
inlet tubing. Each inlet tube is
threaded vertically through an inside wall.
Located in hallways, and in large rooms, the inlets are placed to
provide maximum access to all cleaning areas. See Figure 1.

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.
As an aid in planning the installation in either new or existing
construction, look at the following examples. You should be able
to adapt the examples shown to your specific home layout.

INLETS
A double-trunk line system is commonly used in two-story houses.
INLET
In the installation shown at left, the power unit is mounted in the
LINE
basement. The intake tubing runs up the basement wall and
INLET
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 branch lines connect to inlet lines which are dropped

down through upstairs interior walls. See Figure 2.
Like the two-story house, the split level installation
commonly calls for a two-level trunk line. Here,
the power unit is located in the garage.
The intake tubing runs 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 interior walls. A
vertical branch line runs to the
upstairs attic, where the trunk

line branches into a T-shape.
LINE
This trunk line connects to two
upstairs inlet lines and to one
INLET
inlet line which drops through
an upstairs wall and down into
the third-level utility room to service
this entire level. See Figure 3.
