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

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.
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
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
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.
