NuTone CV556 System Planning and Layout, Ranch Style House, TWO-STORY House, SPLIT-LEVEL House

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.

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.

Here the power unit is mounted EXHAUST
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	UNIT

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.

INLET

LINE In the installation shown at left, the power unit is mounted in the

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
INLET	line branches into a T-shape.
LINE	This trunk line connects to two
INLET	upstairs inlet lines and to one
	inlet line which drops through

an upstairs wall and down into the third-level utility room to service this entire level. See Figure 3.
