Congratulations, you have joined the growing number of households
to enjoy the many benefits of owning an Aussie Vac ducted vacuum
cleaning system.
This kit contains all the materials that you will require to install the vacuum system
including Vaculine fittings. Vaculine fittings are manufactured to exacting standards
to provide positive seals, easy installation and superior air flow characteristics.
Installing a ducted vacuum system is a straight forward do-it-yourself project that doesn't
require special tools or skills. The procedure is quite simple if you take your time and
follow the instructions carefully. Always fully consider the implications before you cut into
a wall. Make sure you have chosen the right location and are not cutting into any hidden
electrical wires or plumbing.
P lan Ahead! Planning is the key to the successful installation of a ducted
vacuum system. A balance between the best locations
for the inlet valves and the practicality of servicing these
locations must be obtained. With a little ingenuity most
locations can be reached.

Power LJnit location
••• The power unit can be located in a garage
(preferably attached to the house), under the
house (with a minimum 15m clearance) or in
a plant room or store room. It should not be
located in an area having excess heat. A large
closet or closed area can be used as long as it
is well ventilated. Louvered doors on a closet
will enable air to circulate and exhaust freely.
It is best not to install the power unit inside
the house unless the exhaust can be
vented outside.
The power unit must be installed at least 200mm
off the ground to allow for air circulation. If youare running the pipe work directly through a
wall to the machine location the pipe should
be approximately 900mm above ground level.

The unit must be located within 1m of an electrical outlet. If you have no suitable undercover
areas to install your power unit, an Aussie Vac weather proof machine is available.
Constructed of galvanised steel, it needs no coverings or canopy.
In let Valve Locations
••• Correctly positioned inlet valves will ensure
trouble-free vacuuming over the may years
of service that will be received from a ducted
vacuum system. The hose must be able to
reach every corner of the house and go around
furniture to get there. Drapes, closets and
ceiling corners all must be reached. Central
locations such as hallways, beside doors and
adjacent to the bottom of staircases are ideal.
Areas such as behind furniture or behind doors
should be avoided. A 9m string or the hose
itself can be used to help plan the layout. If
working with 1:100 scale house plans, a 9cm
string can be used to represent the hose.

Planning the Tubing System• • • 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. Tight 90° fittings are to be used only at inlet valve
locations and sweep 90's used in all other applications.

Figure of Typical Installation
1. The Trunk Line 2. B ranch Lines
The trunk line connects the furthest inlet valve
to the power unit. All other inlet valves will
be serviced by branch line flowing into the
trunk line. The location of the trunk line will
greatly depend on the construction of the
house and the location of the power unit.
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. 45° fittings should
be used to avoid sharp corners when possible.
Airflow direction should always be considered
when installing branch lines.
Avoid G ravity D rops!••• A branch 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 following techniques should be used.

Cutting and Cementing PVC
Tubing and Fittings• •• Measuring: Measurements should be taken from the base
of the pipe-stop on the inside of the fitting when sizing tubing.
As each section of tubing is cut it should be dry fitted before
the next measurement is taken.
Cutting: The tubing should be cut as straight and square
as possible. A meter box should be used if available.
All rough edges must be removed with a utility knife
or coarse sand paper.
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 utilised to assure proper alignment.
Gluing: PVC solvent cement actually welds the fitting to the
tubing. A chemical reaction permanently joins the molecules
from each surface to produce an airtight seal.
Before cementing, both the tubing and the fitting must be
free of PVCburrs, dirt and grime. The components should
be wiped with a clean cloth if necessary. Cement should be
applied to the tubing only, as cement applied to the fitting will
be pushed ahead and create a rough bead on the inside of
the fitting. This bead will reduce airflow and could cause a
clog. The tubing should be inserted all the way into the fitting
and twisted a quarter turn to evenly distribute the cement.
All excess cement should be removed with a rag. The glue
should be allowed several hours to set before the vacuum
system is used.
Low Voltage W ire• •• One of the greatest benefits of ducted vacuum systems
is that the power unit is turned on and off automatically.
Every power unit has an on/off switch that is activated by
completing a circuit at the inlet valves. The power unit is
turned on by simply inserting the hose in the inlet valve.
The wiring used in an Aussie Vac system is 24 volt AC.
There is no polarity therefore you cannot get the wires mixed
up. Just make sure the bare wires do not touch each other.
Simply run the wires to follow the same lines as the pipe
work. Hold the wires in place with the clips on the pipe
saddles included in your kit. Leave about 1Ocm of excess
wire at each end point to connect when you fit off the system.

Insta llation in an Existing Home
Overhead••• If the house has no sub floor access, crawl
space, or is built on a concrete slab, the
ductwork will be run through the roof back
to the power unit location. The ductwork is
clipped to the rafters and dropped down
through cupboards or other floor to ceiling
joinery and bought out through the side or
rear to fit off.

Inlet Valves
••• If you are installing your system underneath the floor and
have no cupboards or other joinery which you can use to
run your pipes through, the inlet valves may be fitted directly
into the floor. The same inlet valve is used but you will need to
substitute the wall mounting plate for a floor reducer coupling.

I nsta Ilation
in a New Home• • • After the house has been wired and plumbed, but before plastering,
isthe best time to install a central vacuum tubing system. Locate the
inlet valve locations and nail the mounting plate to the nearest stud.
Make sure the middle of the mounting plate is at the same height as
the middle of adjacent electrical outlets.
It is best to offset the tubing using a combination of a tight
90° fitting and a 45° elbow. This will avoid problems of
mounting screws puncturing the tubing as well as allowing the
hole to be drilled further away from the stud where nails could
ruin the hole saw. Drill a 57mm hole in the centre of the top
or sole plate depending on the location of the trunk line.
Attach low voltage wire to the tubing and push the tubing
through from the floor below and cement it to the 45° fitting.
Leave 10cm of low voltage wire at the mounting plate for
valve installation when the house is completed.
If the house is being built on a concrete slab and the pipe work
can not be run through the roof, 50mm I.D plumbing pipe and
16mm electrical conduit for the low voltage wires can be buried
in the packing sand before the polythene is laid.
Fitting off the System• • • Once the house is completed or the pipes have all been
installed for an existing house, the inlet valves must be fitted.
Bare 10mm of the low voltage wire leads and wrap them in a
clockwise direction around the lugs on the back of the valve.
Tighten the lugs with a screw driver. Using a twisting motion
insert the valve into the hole with the hinge at the top of the valve.
Do not apply glue; the gasket in the mounting plate will provide
a positive seal. If the valve will not reach the mounting plate
ask your dealer for an inlet valve extension. Using the screws
supplied, attach the inlet valve to the mounting plate. Use the
extra short screw if the longer version is going to penetrate
the tubing behind.
Note: Do not over tighten. If a whistling develops during
operation slightly loosen the screws.
