Read these instructions carefully. Installation of the central vacuum
system is easy and can be performed with regular hand tools. The
system can be installed both in new and existing buildings. When
using a central vacuum system, it is important to make sure there is
a sufficient compensation air supply. Normal ventilation ensures that
there is enough compensation air. This central vacuum system is very
useful, and you can enjoy it for years to come.
Location of the Power Unit
Place the power unit preferably in a heated area like the utility room,
garage, storage room, or laundry room. If the power unit is installed in a
cold storage room, the vacuum tubing and the exhaust pipe should be
insulated in order to avoid condensation.
In buildings with two or more stories, it is recommended to always place
the power unit on the lowest floor. If the equipment is placed on the upper
floor, the power unit must be more powerful so that even the heaviest
dust particles can be vacuumed and transferred into the dust container.
When selecting the installation location, it is recommended that you
ensure that the placement does not disturb your neighbors or interfere
with your own comfort and activities. Make sure that there is a wall outlet
nearby for connection to the electrical network. If you are not sure about
the placement, contact your local building inspector or fire authority for
more information.
Location of Wall Inlet Valves
Wall inlet valves can be placed in the wall or in the floor. Place the inlets
preferably so that you can reach every corner of the room with a vacuum
hose that is 27 to 33 feet long (8m to 10m). There is a utility valve in the
power unit, which allows you to conveniently clean the space where the
vacuum is located and close-by areas, thus eliminating the need to install
another inlet valve and tubing route.
Marking the Placement of the Inlet Valves
Mark the installation points of the inlet valves in the layout drawings using
wire of the same length as the actual vacuum hose. When using drawings
scaled 1:1000 the wire length is 3 1/4” (8 cm), and when using drawings
scaled 1:50 the wire length is 6 1/2” (16 cm). Suitable places for inlet
valves are entrance halls, hallways, etc.

Tubing System Design
The main principle for designing the layout of the tubing system is to
keep it as short as possible. This will give the highest possible vacuum
performance. However, the main tube can be routed in different ways.
The outside diameter of the tubing system is 2” (50.08mm) and is 2 1/8”
(56mm) at the extension. The through-holes in the walls must be 2 3/16”
to 2 1/2” (55mm to 60mm) in diameter so that the extension and the lowvoltage cable can also go through the opening. The minimum diameter of
the exhaust tube is 2 1/8” (56mm).
New One-Story Houses
The horizontal main tube is placed in the under-house crawl space or in
the attic. In the under-house crawl space, the tubing should be insulated.
Tubes to the inlet valves are routed in the partition walls or between
secondary spaces, such as closets. In a cold attic, the tubes should be
covered with insulation in order to avoid condensation.
In a typical house only two inlet valves are needed. In such cases, the
utility valve of the power unit can
be used for cleaning the basement
because it often covers the whole
basement area.
In this example, the main tube has
been routed under the house. However, the tube in the under-house
crawl space should be insulated to
avoid condensation.
In the house of the same size, the
power unit is in the garage, where
the utility valve serves as a third
inlet valve allowing you to clean
your car, for example.
In this example, the simplest
solution is to route the tubing in
the attic. If the space is cold, the
main tube should be insulated.
Two- or Multi-Story Houses
The main tube is placed in the under-house crawl space, attic, closet,
between walls, etc.
Existing Houses
The main tube can be installed on the surface in existing secondary
spaces, such as a garage or storage room. The tube can also be routed
through the attic and then vertically inside the partition walls and closets
all the way to the inlet valves. A lowered ceiling and closet footings can
also be used for routing of the tubes.
The whole floor area can often be
vacuumed from one single inlet valve. The light, broken line indicates
an alternative installation type.
It is recommended to place the
inlet valves in between different
levels. In such cases, you can easily clean two levels from one inlet
valve. The power unit is placed in
the storage room.

Installation of the Wall Inlet Valves
For the installation, you will usually need the following parts:
Inlet valve
Mounting bracket
90° elbow
Wall Installation of the Inlet Valve
A typical wall inlet valve installation is shown in the figure on the right.
A 90° inlet elbow is used in the wall installation to prevent long objects
entering into the tubing system, protecting it against blockages.
A 90° steep elbow can be fitted in two different ways. In practice, the
partition wall can be as narrow as 2 3/4” (65mm).
Note! A 90° inlet elbow must not be installed anywhere else in the tubing
system.

If the Structures of the House Prevent Tubing Routing
This can be avoided by making slots as shown in the figure below.
Supporting structural elements of the house should not be slotted. If you
cannot attach the mounting bracket properly to the batten wall, you can
install a separate mounting board.

Inlet Hole
Make a hole in the board material for the inlet valve as shown in the figure.
The size of the rectangular opening should be 2 3/8” x 4 3/4” (60mm x
110mm). In existing houses where tubes are routed underneath, a hole can
be drilled for the tube using a guide hole as a template. Glue the 90° inlet
elbow onto the sleeve of the mounting bracket. Leave a gap of approximately 5/8” (15cm) for the low-voltage cable to be connected to the inlet
valve. Then the dust tube is glued into the inlet elbow.
Do not disconnect the mounting screws
completely. Loosen them enough to fit
the low voltage cable around them and
then tighten.

Installation in a Brick or Concrete Wall
When installing the inlet valve, sink the pipes, the inlet elbow, and the
mounting bracket in the wall so that the highest surface of the mounting
bracket is approximately 1/4” (5mm) deeper than the final inner surface.
For the tubing system, make a 3 1/8” x 3 1/8” (80mm x 80mm) channel
in the brick or concrete wall independent of the final thickness of the wall.
The tubing installation must be sturdy enough so that tubes and parts
do not move out of their positions later during the installation work. It is
recommended to cover the opening of the inlet valve to protect it from cast
material.

Strip off approximately 1” (2cm to 3cm) of the insulation from the end
of the low-voltage cable. Roll the end of the cable two turns around the
screws in the inlet valve and tighten the screws.
Screw the inlet valve into the mounting bracket and make sure that the
screw does not extend through the tube. If necessary, use shorter screws.
In a complete wall structure, the mounting bracket is held in place by a
hook as shown in the figure.

Choose a location and make a 2 1/8” x 2 3/4” (55mm x 70mm) opening
for the inlet valve. For the tube, a 2 3/8” (60mm) diameter hole is needed.
Drill a hole for the tube also in the floor of the closet. Cut the tube to the
proper length and glue it into the rebuilding sleeve.

For a floor installation, it is recommended to use the method shown in the
figure, if applicable. It is the same as for the wall installation. The 90° inlet
elbow prevents long objects from accessing the tubing system. For this
method to be successful, the allowance under the floor should be at least
2 2/3” (65mm).
For floor installation, it is possible to use the floor sleeve or rebuilding sleeve. In such cases, the mounting bracket is not needed.

Tubing System Installation
Begin the main tube installation with the farthest inlet valve and place the
tubes temporarily at first. Do not glue the joints yet until you have made
sure that the tubing routing is correct. The glue will dry quickly; therefore,
Important notes for installation!
1) The 90° inlet elbow may be installed only together with the mounting
bracket and the inlet valve. Anywhere else in the tubing system, 90°
sweep elbows and 45° elbows should be used. (Fig. A and B)

the joints have to be fitted right after applying the glue.
When measuring the tubes, take into account that the tube goes approximately 2/3” (18mm) into the sleeve and approximately 7/8” (20mm) into
the extension tube.
The tubing system can also be installed in a floor that will be concrete
casted later on (Fig. F). In such cases, the low-voltage cable must be
protected by a conduit pipe. The conduit pipe should be attached to the
vacuum tube or the casting net. For the vacuum tube, the routing channel
has to be 2” wide (51mm). The ends of the vacuum tubes and the conduit pipes should be plugged before concrete casting.

2) Tubes are cut straight so that the cutting line is not slanted. Use a miter
saw if possible. Cut edges can be finished with a knife (to remove burrs).
3) For tubing joints, use suitable PVC glue to make the fittings secure and
tight. Apply a thin and even layer of glue only to the end of the tube – not
to the sleeve. This will prevent the glue from overflowing to the end face
of the tubing. Close the glue can carefully immediately after use and make
sure to have adequate ventilation during installation. Avoid inhaling glue
vapors. Insert the tube all the way into the sleeve while turning it at the
same time (Fig. C).

Notes!
Minimize Condensation
If the tubing installation is carried out in winter, a large amount of condensation may be generated. To reduce the amount of condensation, close all pipe holes and inlet openings using duct tape during installation. Before starting to use the central vacuum system for the first time, let the system vacuum and circulate fresh air for a few minutes, and
make sure that there is no water in the dust container. If there is water in the container, drain it and continue vacuuming until no more water is accumulated.

to change it afterwards. In these installations, only certified electrical
components may be used.
