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.
