lProtect your eyes whenever you are working around power tools
and construction debris - Wear Safety Glasses.
lBe careful when drilling to check for electrical wiring and
plumbing.
lCheck your local Building Code for any regulations governing any
of the phases of your installation.
lUse common sense.
lIf you are in doubt about any portion of the installation, call a
professional to have it done for you.
The CentralVac Built-in Cleaning System is designed and built for
years of use. Protect your investment by reading these instructions all
the way through. This will give you a basic understanding of the system
and you will know what to look for as you plan and complete your
installation.
Planning and Installing Your CentralVac Built-In Cleaning System
The secret to a successful installation is planning. Plan everything on
paper before you start cutting holes in your walls.
You should check the entire home, noting wall and basement construc-
tion details, such as joist direction, location of heating ducts, plumbing,
etc. This will help you determine the best path for the tubing system
and the best location for the power unit. Tubing can run overhead, in
the basement, and up into partition walls to inlet valves. It can also run
inside a wall to a crawl space or attic, and from this point over to
partition walls and down to the inlet valves.
1. Determine the location for the Power Unit and
Canister.
2. Determine the locations for the Inlet Valves.
3. Determine the location and path for the Tubing
System.
4. Gather the tools and materials.
5. Install the Power Unit and Canister.
6. Install the Inlet Valves.
7. Install the Tubing System.
8. Test the System.
Use a map wheel where blueprints (w/scale) are available.
One final tip to remember when planning, you can never have a power
unit that is too big, or have too many inlets in your home!
Warning
Before drilling any holes or making cuts in walls or
floors, take extreme care to determine the locations
of electrical wires, plumbing or other obstructions
that could create a hazard.
You can install the system yourself if you have some remodeling or con-
struction experience. Atypical installation takes about one weekend. If
you are ever in doubt about part of your installation, contract with a pro-
fessional.

The power unit and canister will mount in the basement,
garage, utility room, or other remote area, preferably on a
firm, outside wall away from heat-producing units, such as a
boiler, water heater, dryer, etc.
lLocate the power unit away from the general living
area.
lDo not install the power unit in the attic.
lDo not locate the power unit close to a source of
extreme heat (i.e., water heater) or in an area with
high ambient temperature (i.e., attic, furnace room).
lIt is important that you also plan the installation of an
exhaust tube to the outdoors if ventilation is not
adequate. It is usually best to exhaust out the rear of
the house avoiding patios, windows, and entrance
areas.
lLocate the power unit in an accessible area for ease in
changing the paper bag filter and periodically cleaning
the cloth bag filter.
lLocate the power unit within 4 feet of a grounded elec-
trical outlet. The power unit requires a 120 VAC power
source with sufficient capacity to service the unit.
lDo not use extension cords.
lIf the power unit is located in a closet or a small utility
room, make sure the area is well-ventilated (i.e., with
door louvers).
lThe power unit has an auxiliary inlet for a garage,
basement, utility room, etc. However, installing a
separate inlet is the preferred method. It is more
convenient to use a hose with an inlet valve which
uses a low voltage control circuit to start and stop the
power unit automatically, than to use the auxiliary inlet
which must be switched on and off manually.
Determine the Location of the Power Unit
Determine the Size of the Power Unit
There is not a simple formula for choosing the correct size power unit
for your cleaning system. If you live in a high altitude area (5,000 to
7,000+ ft. above sea level), you may need to move to the next larger
size power unit, or go with a double motor unit.
Remember, you can never have a power unit that is too big, or have
too many inlets in your home!

Determine the Locations of the Wall Inlets
Inlets are usually located centrally in the
house in hallways, near doorways and near
the bottom of stairways. It is important to
overlap areas covered from each inlet valve to
assure thorough cleaning of the entire home.
Inlet valves placed in halls and near doorways
provide the maximum amount of cleaning
coverage from the minimum number of valves
frequently making it possible to clean three or
four rooms from one inlet. Valves in these
locations are seldom if ever obstructed by
furniture placement. An inlet located near the
bottom of the stairway permits easy,
convenient cleaning of the stairwell and sur-
rounding areas.
lStart with the area of the house farthest
from power unit and tentatively select an
inlet location that will provide maximum
cleaning coverage.
lIf possible, locate the inlet close to an electrical outlet, to be able
to use electric power heads.
lUsing a 30 foot length of cord, check to be sure all adjacent areas
of the house can be cleaned from this location.
lAllow sufficient slack in cord to provide for furniture placement
and wall offsets. Be certain all areas can be cleaned including
walls and ceilings.
lMark the location of the first inlet valve and proceed toward the
power unit, locating additional inlet valves until all parts of the
house can be comfortably reached with the hose.
It is preferable to plan on using wall inlets, however, the same inlet can
be placed in the floor if tubing cannot be installed in the wall. Wall
inlets should be installed to match the height of electrical outlets.
Airflow Rules
l90oSweep Tees should always be installed in the direction of air
flow toward the power unit.
l90oSweep Tees should never be installed with the sweep pointing
down, because the dirt will fall to a lower level, and not be carried
to the power unit.
l90oShort Tees should be installed only on inlet valves.
lUse no more material (tubing, fittings, etc.) than is necessary. Less
tubing and fittings means more performance.
lIt is important to have a sealed system. Cut and glue your pvc
joints carefully.
lThe total distance from the power unit to the furthest inlet should
be less than 200’.
lThe length of the exhaust pipe should be less than 30’.
lAslight amount of slope toward the power unit will help your
system carry dirt and debris and avoid plugs.
lUse only CentralVac 2” plastic pipe. Do not use any other type.
CentralVac plastic pipe is much thinner and lighter, .06” wall
thickness, and is designed for vacuum applications.
lAbranch line located directly below an overhead trunk line will
accumulate dirt due to the effects of gravity. The result will be a
pile of dirt at the base of the inlet valve every time it is opened.

The amount of airflow that reaches the hose is dependent on the
efficiency of the layout of the tubing system. Lines are to be kept
as straight as possible.
The Trunk Line
The trunk line connects the furthest inlet valve to the power unit.
All other inlet valves will be serviced by branch lines flowing into
the trunk line. If the basement is unfinished, the trunk line is best
run beneath the joists in the basement ceiling. The upper floors
can be serviced through closets, cold air return ducts, or in
partition walls. The trunk line could also run straight up to the
attic and service the floors beneath by branch lines dropping
through closet ceilings or partition walls. The location of the trunk
line will greatly depend on the construction of the house and the
location of the power unit.
Branch Lines
Branch lines join the remaining inlet valves to the trunk line. As
with the trunk line these lines should be kept as straight as
possible. Forty-five degree fittings should be used to avoid sharp
corners when possible. Airflow direction should always be
considered when installing branch lines.
Abranch line located directly below an overhead trunk line will
accumulate dirt due to the effects of gravity. The result will be a
pile of dirt at the base of the inlet valve every time it is opened.
To avoid this situation the illustrated techniques should be used.
Planning the Tubing System

The Two or Three 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. Asecond trunk line runs across the attic and two branch lines connect to inlet lines, which are dropped
down through upstairs interior walls.
The double-trunk line system is commonly used in two or three story houses. Finding the “Key” to an accessible vertical area is the most important
step in this kind of installation.
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. The inlets located in hallways,
next to doorways, and in large rooms, provide maximum access to all cleaning areas.
Tubing System Planning Examples

Cutting and Cementing PVC Tubing
and Fittings
Measure Twice, Cut Once
1. Measuring: Measurements should be taken from the base of the
pipe-stop on the inside of the fitting hub when sizing tubing. As
each section of tubing is cut, it should be dry fitted before the next
measurement is taken.
2. Cutting: The tubing should be cut as straight and square as
possible. Aplastic pipe cutter or a miter box can be used. All rough
edges must be removed with a utility knife or coarse sandpaper.
3. Dry Fitting: Once all the pieces are cut they should be dry fitted to
check for correct fit. The markings on the fittings can be utilized to
assure proper alignment.
4. Cleaning: Before gluing, both the tubing and the fitting must be
free of plastic burrs, dirt and grime. The components should be
wiped with a clean cloth if necessary.
