1. Overview of REHAU-VACUCLEAN
1.1
System description
The REHAU-VACUCLEAN central vacuum
cleaner system consists of a central vacuum
unit and the sound insulating
RAUPIANO Plus pipe system laid in the
building.
You can conveniently vacuum with the
telescopic tube and the 6 m or 8 m suction
hose without having to move a heavy
appliance from room to room or over stairs.
You simply insert the suction hose into the
suction socket and switch on the central
vacuum unit with the remote radio control
system. The central vacuum unit starts
powerfully drawing in air without any
bothersome loud motor noises.
With the REHAU-VACUCLEAN central
vacuum cleaner system, exhaust air no
longer ends up in the room with you, as it is
directed outside through filters. This is
important for those with dust allergies and
asthma, who would immediately notice the
difference with common vacuuming
methods.
The air full of debris is transported from the
individual suction sockets to the central
vacuum unit through the sound insulating
RAUPIANO Plus pipe system.
This is installed in a lower room (e.g. cellar).
Using a special filtering technique (cyclonic
separation) and a downstream cartridge filter,
the air sucked in is cleaned before being
released outside.
Alternatively, a wall vacuum connection VacPan can be installed instead of a suction
socket for drawing in swept waste.
+ Easy handling, as just the suction hose
is moved
+ Strong and consistent suction
performance
+ Minimal noise generation
+ Diversion of microscopic dust into the
open
+ Smooth pipe interior
+ Maintenance-free, sound-insulating
RAUPIANO Plus pipe system
+ Resistant to abrasion
+ Low-pressure resistant

2. Planning
2.1
Planning information
Warning!
Risk of death!
Disregarding the fire-protection
regulations and measures risks death and
severe burns to users/tenants.
➜ Observe fire-protection regulations and
building codes of practice/regulations.
■ It is not necessary to provide each
room with a suction socket. The
required number is determined during
the planning phase.
■ The vacuum pipes may be mounted
on or inside the wall.
➜ Lay the pipe system as short and
straight as possible.
➜ Install the suction sockets near doors
so as to cover several rooms. This
installation location also ensures that
the suction sockets are not blocked by
furniture.
➜ For garages, install suction sockets
near the garage door so that you can
clean your car comfortably outside the
garage.
➜ Take an under-roof floor which can be
finished into account during planning
and execution.
2.2
Planning stages
1. Acquire correct-scale ground plot
diagrams of the building (scale 1:100).
Fig. 2-1: Drawing ranges
2. Draw the ranges (green lines) on the
ground plot diagrams (see Fig. 2-1):
- Determine the working radius: For this
purpose, deduct 1 m from the length of
the suction hose.
Length of the suction hose:
6 m for Item No. 242483-001,
8 m for Item No. 242473-001.
- Draw the working radius from the outer
corners of the ground plot with the
compass.
Fig. 2-2: Providing suction sockets
3. Provide suction sockets in the overlap
areas (shaded green) (see Fig. 2-2):
- If two circles overlap: Install a suction
socket in each overlap area.
For optimal use of the working radius of
the suction hose: Select the final
position of the suction sockets in such a
way that the non-shaded areas are also
covered with the suction hose.
- If all the circles in a common area
overlap, e.g. in small flats, a single
suction socket is sufficient for each flat:
Provide a suction socket in this area.
- If no overlap areas arise when planning
for larger structures: Provide additional
suction sockets.
Fig. 2-3: Drawing working radius
4. Draw the working radius from the planned
suction socket as a checking measure (see
Fig. 2-3):
- Check whether all areas to be cleaned
are within the working radii.
- Check whether partition walls limit the
working radius.
5. Determine the installation site of the central
vacuum unit:
- Always install the central vacuum unit
toward the bottom of the building.
- If suction occurs against the pull of
gravity in sections of the suction pipes:
Comply with the usage limitations (see
Chap. 4, Page 13).
6. Determine the design length to select the
unit type:
- The design length corresponds to the
pipeline length from the central vacuum
unit to the furthest suction socket plus
the length of the exhaust air pipe.
- Take the following equivalent lengths
into account with the design length for
each redirection (bend, branch):
45° bend: 0.5 m
90° bend: 1.0 m
Branch: 0.5 m
7. Select the central vacuum unit with the
appropriate performance using the
calculated design length (see Table 4-1,
Page 13).

3. Building types
Single family dwelling
We recommend implementing distribution in
the cellar when planning the pipe system.
If there is no cellar under the house, the
central vacuum unit can be installed in a
storage room.
The floors of the house are passed through
with vertical pipelines and connected up to
the suction sockets.
Multi-family dwelling
A pipe system and separate vacuum unit is
provided for each flat in a multi-family
dwelling. All central vacuum units can be
installed on the cellar level.
The exhaust air pipes of the individual central
vacuum units can be combined into a larger
collection pipe (e.g. DN 110) downstream of
the sound absorber and directed outside
(see Fig. 3-2).
If each individual flat contains a storage room
with the possibility to install an exhaust air
pipe to the outside, the central vacuum unit
can also be installed here.

Hotels, offices and commercial
use
Two suction sockets can be employed
simultaneously if unit type 4000 is used.
Cleaning zones
The building can be divided into so-called
cleaning zones. A cleaning zone represents
the area cleaned by one person.
The suction sockets of a cleaning zone are
linked with a pipeline and connected to the
desired unit type.
With unit type 4000, two cleaning zones can
be connected (see Fig. 3-3).
Only one suction socket may be used at a
time without a drop in performance with unit
types 2000 and 3000.
Cleaning personnel
The number of required cleaning persons (R)
is calculated from the average cleaning
performance (A = 200 m
2
/h), the area to be
cleaned (F) and the specified cleaning time (t):
R = F / (t x A)
➜ Select central vacuum units, taking into
account the distance to the furthest
suction socket (design length) and the
number of simultaneous users.
Example:
R = 800 / (1.5 x 200) = 2.7
Result:
Three cleaning persons are required.
Cleaning zones 1 and 2
(two simultaneous users)
Design length up to 80 m:
Unit type 4000
Cleaning zone 3 (one user)
Design length up to 80 m:
Unit type 2000
➜ We recommend unit types 3000 and
4000 for commercial use (see Chap. 4,
Page 13).

4. Areas of use
4.1
Radio remote control system
Operation of the remote radio control system
may be limited or fully impeded by cellar
floors made of reinforced concrete or if radioblocking materials (e.g. metal rib mesh, floor
heating with metal pipes, metal wall or ceiling
cladding) are used.
Remote radio control of the central vacuum
unit can be made possible in buildings with
radio-transmission limiting properties by
carrying out the following measures:
■ Place the radio receiver unit of the central
vacuum unit in the cellar hallway or
stairway. A 5 m connection cable is
available for this purpose.
■ If this is not possible or insufficient on the
customer side, the remote radio control
system can be supported by the use of a
repeater (see Chap. 5.8, Page 27).
The repeater can also be used when
upgrading existing systems.
■ Working frequency: 434 MHz, rolling-code
method
The REHAU-VACUCLEAN central
vacuum cleaner system was designed for
vacuuming household dust in buildings.
When using REHAU-VACUCLEAN in
commercial buildings or multi-family
dwellings with larger areas or several

Vacuum pipe
■ Laying pipes in adjacent rooms (e.g. cellar,
garage) can be done via mounting on the
surface under the ceiling or on the wall.
Use a surface mounted suction socket for
this.
■ Laying in screed is not permissible, as it
can shorten due to the temperature and
impact sound insulation. This could cause
leaks at the transition point of the vacuum
pipe from the screed to the masonry.
■ Laying in the outer insulation of a building
is not permissible.
➜ Install vacuum pipes DN 50 in wall slots of
at least 80 x 80 mm.
➜ Take static requirements of the masonry,
especially for horizontal slots, into account
during planning and execution.
➜ Make wall slots in such a way that the
pipeline can be laid without being
tensioned.
➜ Before plastering in, surround pipes and
fittings on all sides with flexible materials
such as corrugated cardboard, mineral or
glass wool or commercial insulation tubes.
➜ Protect pipes and fittings from the effects
of high temperatures with appropriate
measures (insulation) at points where
temperatures over 100 °C are reached
due to external influences.
➜ When laying the pipes and fittings, ensure
that the sleeves point against the direction
of flow.
➜ If installed in a suspended ceiling, check
whether it runs through an inhabited area.
If this is the case, attach additional
insulation.
Laying in concrete
The static condition may not be impaired by
laying in concrete.
➜ Ask a professional for advice before
starting the work.
➜ If cementing in is permissible, secure the
pipe sections in such a way that a change
in position is prevented during cementing.
➜ To prevent penetration of cement slurry,
close the sleeve gaps with tape.
➜ Close pipe openings.
The total weight of the cement may not be
supported by the pipeline. We strongly
advise being very careful when committing
the pipes and fittings to a position, e.g. during
cementing.
➜ Make provisions for the dissipation of the
load in accordance with technical
guidelines, e.g. spacers for reinforced
steels, carrying boxes (folded sheet-metal
edges), consoles etc.

Warning!
Risk of death!
Disregarding the fire-protection
regulations and measures risks death and
severe burns to users/tenants.
➜ Observe fire-protection regulations and
building codes of practice/regulations.
➜ Observe the national regulations for
cut-outs and slots in the masonry.
REHAU recommend acoustically
decoupling the line from the main
structure with commercially available,
moisture-protective impact-sound
insulation (S > 4 mm).
➜ Use joints for the transition into the wall

Other installation sites
The following are also suitable installation
sites for suction and exhaust air pipes:
■ Unused chimney flues
■ Wall slots
■ Hollow-beam ceilings
■ Compensating ballasts
■ Spaces between layers of insulation
■ Elevated floors
■ Lightweight walls
Sweat water formation
Sweat water will form in the pipelines in nonstainless areas.
For this reason, provide all pipelines in the
building in which sweat water will form with
diffusion-proof insulation material.
Closed-cell materials with high water vapourdiffusion resistance are suitable for this. If
open-cell of fibrous insulation materials are
used, they must have an impermeable outer
layer that is firmly attached to the insulation
material.
➜ Close off impact, groove, cut and end
points with a permanent seal.
➜ Cut out insulation in the area of
attachment.
➜ Pull insulation material over the attached
section and permanently seal it to the
neighbouring insulation material with
adhesive.
Installation information
➜ Avoid narrow radii with changes in
direction; 90º bends only immediately
behind the suction sockets.
➜ Along the rest of the pipe, use two 45°
bends or 45° branches with less flow
resistance (see Fig. 5-15).
Fig. 5-15: Installation example
➜ Shorten pipes with a fine-tooth saw and a
mitre box for a right-angle cut.
➜ Deburr the cut area and lightly bezel it to
get rid of edges which could catch debris,
dust or threads.
➜ In unheated rooms, insulate the pipelines
to prevent condensation water from
forming.
➜ Clean the O-ring, sleeve interior and
pointed end before connecting the pipes.
➜ Apply a sliding agent to the pointed end to
facilitate installation.
➜ When installing the vacuum pipes, ensure
that the sleeve is always pointing against
the direction of flow.
➜ To protect against penetrating debris, e.g.
when plastering, vacuum pipes laid under
plaster are to be covered with a protective
sheath or the sleeve gaps are to be closed
with tape.
➜ Install branches upward or to the side only,
so that debris in transit does not fall into
the suction pipe below (see Fig. 5-16 and
Fig. 5-17).
Fig. 5-16: Downward branch – installed
properly
Fig. 5-17: Downward branch – installed
incorrectly
➜ If a suction socket must be installed below
the suction pipe, first install the branch
horizontally and then lead it downward
with two 45° bends (see Fig. 5-16).
A gradient need not be provided for
horizontal sections of the suction pipe.
23
Implementing pipe cleaning openings
➜ Install a branch instead of a 45° bend at
redirection points.
➜ Provide additional outlet with a dummy
plug (see Fig. 5-18).
➜ Remove dummy plug for cleaning.
Fig. 5-18: Cleaning opening
Connecting central vacuum unit to
vacuum pipes
➜ Connect vacuum pipes to the central
vacuum unit with RAUPIANO Plus double
sleeve.
Securing vacuum pipes
Recommended spacing of pipe brackets:
■ for horizontal pipes: up to 0.5 m
■ for vertical pipes: up to 1.0 m
➜ Secure vacuum pipes with fixed brackets
or guide brackets mounted to the wall with
hanger bolts and plastic plugs.
➜ Attach fixed brackets directly after the
sleeve.
➜ For lengths of 1 m or longer, use guide
brackets as well.
5.6

5.8
Repeater
Unit description
The repeater extends the range of the remote
radio control system.
Installation site
After programming the repeater is to be
plugged into a socket within the area within
which the remote radio control system still
functions without the repeater (preferably
about in the middle of the area).
Example
The radio receiver unit is positioned in the
house cellar. The central vacuum unit can no
longer be switched on and off using the radio
sender unit as from the 2nd floor. The remote
radio control only functions between the
cellar and the 1st floor without a repeater. A
repeater in to be plugged into a socket about
in the middle of the area from the cellar to the
1st floor, for example in the ground floor.

Installation information
5.9.2.1
Control cable
The central vacuum unit is switched on and
off via a control cable (that is laid parallel to
the pipes). The control cable of the suction
sockets is linked to the central vacuum unit
by means of a parallel connection.
➜ Let the control cable project approx.
20 cm at the mounting site of the suction
socket.
➜ Connect the control cable at the suction
socket. Connect with common lamp-wire
connectors at branches and tape with
insulating tape.
➜ Fasten the control cable with at least
2 cable ties per meter of pipe or with
adhesive tape.
At 24 V the control voltage lies within the lowvoltage range. The control cable can
therefore be laid by a layperson. REHAU
nevertheless recommends that a qualified
person be consulted.
5.9.2.2
Vacuum pipe
■ Laying pipes in adjacent rooms (e.g. cellar,
garage) can be done via mounting on the
surface under the ceiling or on the wall.
Use a surface mounted suction socket for
this.
■ Laying in screed is not permissible, as it
can shorten due to the temperature and
impact sound insulation. This could cause
leaks at the transition point of the vacuum
pipe from the screed to the masonry.
■ Laying in the outer insulation of a building
is not permissible.
➜ Install vacuum pipes DN 50 in wall slots of
at least 80 x 80 mm.
