3.1. System for one user
For systems for one user, lead the piping from the wall inlets to the central unit using the shortest possible route. The
wall inlets can be branched from one Ø 44 mm pipe. One suction pipe leading to the central unit and one exhaust air
duct leading outside are enough.
1. Usages
The Allaway Manta central vacuum cleaning system is intended for professional usage in places where large areas
need to be cleaned, with equipment that is used for longer periods than normal domestic use, and where the systems
have several simultaneous users. Typical usages include hotels, ofces, sheltered homes, passenger ships, daycare
centres, and schools. The Allaway Manta central vacuum cleaning system is also often used in libraries, theatres and
concert houses, and other public buildings. Industrial applications include ofces and other such spaces.
The Allaway Manta central vacuum cleaning system cannot be used in industrial production facilities where the
amount of dust and rubbish being cleaned is large, or the pieces being cleaned are large and heavy, such as chippings
from machine tools, pieces of metal thread, or oily pieces. The Manta system is also not suitable for places where the
objects to be vacuumed differ from normal household dust and rubbish, or for local extraction of welding ue gases,
soldering, etc.
Only durable wall-inlet-started cleaning equipment with steel handle pipes and telescopic wands may be used in the
Allaway Manta central vacuum cleaning system. Due to the control technology used in the Manta system, handle-
started cleaning equipment may not be used.
2. Legislation and regulations
There are no comprehensive re safety regulations or instructions for central vacuum cleaning systems. The construction
instructions and regulations for the installation country and the general quality requirements for HPAC construction
must be applied in the planning and installation of the system.
The heat insulation and airtightness of the exhaust air duct must be sufcient. This is the case when using sheet
metal ducts. In addition, the integration to any necessary protective appliances, such as re shutoff valves, must be
accounted for in the selection of the exhaust air duct. The locations of the exhaust holes are determined according to
the applicable construction regulations.
The noise level of the central unit must be considered when selecting its location.
TheAllaway suction piping is made of environmentally friendly recyclable plastic material (PP or PVC). The suction piping
is usually made using Allaway dust pipes, but other pipes may be used for special installation sites. The regulations
and instructions for plastic drains are applied for the leadthroughs in compartmentation doors.
3. The Manta central vacuum cleaning system

3.2. System for several users
Two basic points are used as the basis for the planning:
1) The amount of air vacuumed simultaneously by two users does not t to one Ø 44 mm dust pipe.
2) If larger pipes were used for the dust piping, the ow rate would be insufcient with only one user.
If the spaces to be cleaned are divided into cleaning areas according to the requirements of the usage situations, this
will guarantee a sufcient ow rate in the dust piping in all usage situations. Expensive and noisy by-pass systems
are not needed, and the central vacuum cleaning system is energy-efcient.
Cleaning areas can include the various parts or oors of the building. In hotels, the rooms can be divided into cleaning
areas of the same size based on the number of rooms or the side of the corridor that they are on. Only one user can
work on one cleaning area at any one time. A layout of the division of the cleaning areas must be made for the users
in systems with several users. Locate the layout in a visible place, such as next to the hose holder.

5
In buildings with several oors, the Ø 75 mm collector pipe of the central unit can be led vertically through the oors,
or the Ø 44 mm dust pipes from the cleaning areas can be joined on their respective oors. This requires the location
of the central unit to be directly below the collector pipe. The collector pipe must never under any circumstances be
designed to be horizontal. The largest angle allowed for the collector pipe is 45°.
The most important issue when planning a system for several users is to lead a separate Ø 44 mm dust pipe from
the cleaning area to the central unit. The pipes from the various cleaning areas must not under any circumstances be
connected before the Ø 75 mm central unit collector pipe.

4. Technical information for the central units
The temperature of the motor or turbine may rise to almost 80SDgrC. The turbine is
equipped with thermal protection at 80SDgrC, at which temperature the protection will
turn off the device.
Allaway Manta 3000
The Manta 3000 central unit is designed for one user with the maximum distance of
70 metres between a wall inlet and central unit.
Allaway Manta 6000
The Manta 6000 central unit is designed for two simultaneous users with the maximum
distance of 60 metres between a wall inlet and the central unit. It is intended for one user
per cleaning area.
The system for two simultaneous users also requires the piping to be divided into at least
two separate cleaning areas. If used for one user only, the maximum distance between a
wall inlet and the central unit is 100 metres.
Allaway Manta APC 3
The power of the Manta APC 3 central unit can be adjusted. It is intended for 1-3
simultaneous users. The Automatic Power Control (APC ) considers the number of users
in the system and ensures sufcient suction power, while saving energy if only one or two
users are using the system.
The system for three simultaneous users also requires the piping to be divided into at least
three separate cleaning areas. The maximum suction distance for three users is 60 metres
per user, 70 metres each for two users, and 80 metres for one user. The maximum suction
distance for one user is 100 metres when using the xed Preset frequency setting. The
collector pipe is not considered in the suction distance.

5. Selecting the central unit
Example:
- The oor area to be cleaned is 5,800 m²
- The time in use is 8 hours
- 6 simultaneous users are needed
Solutions:
1) 2 Manta APC 3 central units, if the structure of the building and the location of the central unit are such that the
maximum distance between the furthest wall inlet and the central unit is 60 metres, and that there can be three
simultaneous users per central unit.
2) 3 Manta 6000 central units, if the maximum distance from the furthest wall inlet is 60 metres. The central units can
be located on different sides of the building. There can be two simultaneous users per central unit.
3) 6 Manta 3000 central units, if the maximum distance from the furthest wall inlets is 70 metres.

6. Location of the central unit
Several factors affect the location of the central unit. The following section
discusses the situation for one central unit. The same principles can be
applied for solutions with several central units, if the total area to be cleaned
is divided into separate areas for each central unit. At least the following
issues must be considered when planning the system:
6.1. Length of the dust piping
The distance from the furthest wall inlet to the central unit must be within
the limits dened for each central unit. If at all possible, locate the central
units close to the centre of the area being cleaned, in order to regulate the
length of the dust piping. In addition to cost savings, a shorter dust piping
willl also achieve improved cleaning efciency.
6.2. Requirements for the location of the central unit
The central unit should not usually be attached to a oor, and under no
circumstances to a wall. There should be approximately 1 metre free space
in front of each central unit for maintenance purposes. Several central
units may be installed in the same space next to each other. Also reserve
space for the functional diagrams of the system and the operating and
maintenance instructions. The central unit is usually located on the ground
oor or a cellar, but it can just as well be located one oor higher than the
area to be cleaned. However, the maximum rise in the piping must not
exceed 6 metres.
The central unit must be located in a space where the exhaust air duct can
be led out. The temperature of the installation space of the central unit must
not be under +5°C or over +40°C.
The noise level from the central units is between 65 and 75 dB (A), which
must be considered in the surrounding wall structures The turbine does not
cause structure-borne noise that carries in the structure of the building, as
it rests on rubber legs.
6.3. Maintenance operations on the central unit
Locate the central unit in a space where it can be easily accessed
for maintenance. Good locations include cleaning rooms and storage
facilities in central locations. Avoid distant locations that are not easily
accessed, because this may cause the emptying of the dust canister to
be considered unpleasant, and to be left undone.
6.4. Ventilation of the location of the central unit
Part of the power of the central unit is transformed into heat. Most of the
heat is transferred outside with the exhaust air, but some of it will remain in
the installation space of the central unit when the vacuum cleaner is used.
The central unit produces heat in the installation space as follows:
Manta 3000 500–800 W
Manta 6000 800–1,500 W
Manta APC 3 600–1,500 W
The heat load greatly depends on the surface materials of the cleaned areas.
As an example, cleaning tted carpets produces more heat than cleaning
hard oor surfaces. The ambient temperature of the electric motor of the
central unit must not exceed 40°C, which is why the excess heat must be
removed from the space in question.
The amount of air to be exhausted depends on the length of the period of
use, the size of the installation space, and the wall materials. The general
guideline is that the need for ventilation in spaces of less than 20 cubic
metres is approximately 55-70 l/s per central unit. If this cannot be arranged
through the general ventilation system of the building, for example a
thermostat-operated exhaust fans can be used.

The diameter of the dust pipes in the Allaway Manta
system is 44 mm. With a smaller diameter, the loss of
pressure caused by the ow resistance would be too
great, causing decreased cleaning power. With a larger
diameter, such as 50 mm, the ow rate of air in the piping
would be too small, and the ow of heavy rubbish, such
as stones and sand, would be insufcient. The shape of
the bends and the smoothness of the inside surface are
critical for achieving excellent ow properties. The parts of
the Allaway piping that are particularly exposed for wear,
such as the elbow and branch pieces, are strengthened.
The sleeve joints in the Allaway dust pipes are always
adjusted according to the ow direction, minimising the
risk of blockage.
7. Dust piping
7.1. Features of the dust pipes
The design of the dust piping is crucial for the operation of the entire system. The size and ow properties of the
Allaway dust pipes are developed to ensure a ow rate in the piping of at least 20 m/s in normal use. However, this
requires that the equipment-specic maximum line lengths and numbers of users are not exceeded. At a ow rate of
20 m/s, the dust and even any heavier rubbish will be transferred all the way to the dust canister.
The diameter of the dust pipe must be in line with the power of the central unit, cleaning hose, and cleaning equipment.
8. Installing the dust piping
The dust piping can be installed even in narrow spaces, because the diameter of the pipes is only 44 mm (51 mm
in sleeve joints). However, we recommend installation in easy-to-access places, where the risk of damage during
construction and maintenance is minimised. Enter the pipes and low-voltage leads from each cleaning area in the
plan. he piping should be installed as direct and short as possible, avoiding unnecessary bends and corners.
8.1. Attaching the pipes
Ensure that all parts are in good condition both on the inside
and outside, and clean if necessary. Install the yellow locking
seal inside the sleeve. Push the pipe directly into the sleeve,
rotating the pipe slightly, until the end of the pipe is sealed
to the bottom of the sleeve. The pipe is sufciently extended
when the point of connection of the pipes is over the white
marking line. If you cut the pipe, draw the marking line at the
correct point using another marked pipe. The locking seal
ensures and locks the joint. Branches must always join the
body pipe from above or one side. The joints must be situated
in the correct way, ensuring that there are no collision surfaces
in the piping where shards of glass, toothpicks, nails, etc. could
catch. The arrows in the parts of the piping show the direction
of the ow. When installing the piping, the sleeve must always
be on the wall inlet side of each part. On the exhaust side,
the sleeve must be towards the central unit.

Always connect the elbow coupling to a dust pipe without a sleeve. The sleeve can be cut from an intact dust pipe
using a ne-toothed saw or a pipe cutter. Carefully remove any cutting burr using a sharp knife or le. Chamfer the
outer edges of the cut pipe end.
8.2. Supporting
Support the pipes with pipe clamps or metal clamps. Support the pipes to the framework of the wall, oor, and ceiling.
Select the supporting distance according to the structures. If the distance between the studs is 600 mm, the distance
between the pipe supports should be 1,200 mm or 1,800 mm. Each pipe should be supported. Support the pipes
steadily to ensure that later maintenance near the building’s piping system is possible. Follow the general instructions
and construction regulations in the work specication.
During installation, ensure that the temperature of the piping stays close to room temperature when it is used. Otherwise,
use thermal insulation in the ceiling, for example.
Stretches of piping that are exposed to extreme changes in temperature at the installation phase must be supported
as follows:
Only use Allaway pipe clamps to support the piping (please refer to the picture below).•
Install the pipe clamp in a way that allows the pipe to move freely in the axial, i.e. longitudinal, direction.•
Support the piping in a manner that allows axial thermal expansion and contraction. Sleeve joints in particular should•
not be subject to extension strain as the piping contracts.
Only install the pipe clamps in stretches of pipe without bends, and at a sufcient distance from the sleeve joints to •
enable thermal expansion and contraction. The thermal expansion coefcient is approximately 0.1mm/m/CSDgr.
In order to allow for the movement of the pipe, only one pipe clamp is allowed near an elbow piece, as shown in the•
picture below. The pipe clamp on the other side of the elbow piece must be at least 70 cm from the elbow piece. No
pipe clamps are installed on direct stretches of pipe shorter than 70 cm.
