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.
THE TWO-STORY HOUSE
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 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 branch lines connect to
inlet lines which are dropped down through upstairs
interior walls. See Figure 2.

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.
