System Planning And Layout; Examples - NuTone VX1000C Installation Instructions Manual

SYSTEM PLANNING
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.
THE RANCH STYLE HOUSE
Here the power unit is mounted in the
garage. The intake and exhaust tub-
ing, 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 loca-
tion. 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 left, 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.
