GENERAL INFORMATION

The NuTone Central Cleaning System consists of a Central Power Unit, PVC Tubing, PVC Fittings, automatic switch operated 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 and fittings.

LAYOUT AND PLANNING EXAMPLES

As an aid in planning the installation, look at the following examples.

THE RANCH STYLE HOUSE

Here the power unit is mounted in the

garage. The intake and exhaust tubing,				TRUNK LINE
the only exposed
tubing in the	EXHAUST
installation, runs up						INLET LINE
the garage wall and
into the attic.
The trunk line runs
horizontally through
the attic from the

power unit to the

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

In this installation, the power unit is mounted in the basement, conveniently located for shop use and messy cleaning jobs. 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 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 double-trunk line system is commonly used in two-story houses. Finding the “key” to an accessible vertical area is the most important step in this kind of installation.
