Important notes
Information on the installation manual
This manual enables operating or service personnel
to correctly install the product described below and
to use it safely and efficiently.
It is essential that these individuals read and fully
understand this manual before starting any work.
The basic prerequisite for safe working is to comply
with the safety notes and all instructions in this
manual.
The local regulations for health and safety at work
and general safety regulations also apply.
Qualified staff
Specialist personnel
Specialist personnel are individuals who have sufficient professional or technical training, knowledge
and actual experience to enable them to carry out
their assigned duties, understand any potential hazards related to the work under consideration, and
recognise and avoid any risks involved.
Limitation of liability
The information in this manual has been compiled
with reference to the applicable standards and
guidelines, the state of the art, and our expertise
and experience of many years.
The manufacturer does not accept any liability for
damages resulting from:
Non-compliance with this manual
Incorrect use
Operation or handling by untrained individuals
Unauthorised modifications
The actual scope of delivery may differ from the
information in this manual for special constructions,
additional order options or as a result of recent
technical changes.
Personal protective equipment
Personal protective equipment must be worn for all
work in order to reduce health or safety hazards to
the minimum.
The appropriate protective equipment for a job must
be worn for as long as the job takes.
Industrial safety helmet
Industrial safety helmets protect the head from
falling objects, suspended loads, and the effects of
striking the head against stationary objects.
Protective gloves
Protective gloves protect hands from friction, abrasions, punctures, deep cuts, and direct contact with
hot surfaces.
Safety shoes
Safety shoes protect the feet against crushing,
falling parts, and slipping on slippery ground.
Correct use
Air terminal devices are used for the ventilation of
rooms in industrial and comfort areas. The air terminal devices are connected to a supply air or
extract air system (by others), which is typically
connected to an air handling unit.
Air terminal devices supply cold or warm air to
rooms (within the stated supply air to room air temperature differences).
Installation, operation and maintenance may have
to meet increased hygiene requirements for certain
areas of application.
Important notes
Air terminal devices Slot diffusers, Type VSD...2
The installation of air terminal devices in humid
rooms, areas with potentially explosive atmospheres or rooms with dust-laden or aggressive air
has to be assessed for each individual case.
Transport and storage
Delivery check
Upon delivery, carefully remove the packaging and
check the unit for transport damage and completeness. In case of any damage or an incomplete shipment, contact the shipping company and your supplier immediately. Put the product back into its
packaging after the delivery check to protect it from
dust and contamination.
Fixing and installation material
Fixing and installation material is not part of the
supply package (unless stated otherwise), but
has to be provided by others; it has to be suitable
for the installation situation.
Transport on site
CAUTION!
Danger of injury from sharp edges, sharp corners and thin sheet metal parts!
Sharp edges, sharp corners and thin sheet metal
parts may cause cuts or grazes.
– Be careful when carrying out any work.
– Wear protective gloves, safety shoes and a
hard hat.
If the device has to be moved:
Be careful when unloading or moving the
product, and pay attention to the symbols and
information on the packaging.
If possible, take the device in its transport
packaging up to the installation location.
Use only lifting and transport gear designed for
the required load.
Always secure the load against tipping and
falling.
Do not move bulky items just by yourself. Get
help to prevent injuries and damage.
Storage
Please note:
Store the unit only in its original packaging
Protect the unit from the effects of weather
Protect the unit from humidity, dust and con-
tamination
Storage temperature: –10 to 50 °C
Relative humidity: 95 % max., non-condensing
Packaging
Properly dispose of packaging material.

Installation notes:
Fix the device only to load-bearing structural
elements.
Load suspension systems only with the weight
of the device. Adjacent components and connecting ducts must be supported separately.
Use only approved and adequately sized fixing
material (fixing material is not included in the
supply package).
Refer to the technical leaflets for product
weights and dimensions.
The diffusers must remain accessible for
cleaning even after installation.
Installation and sealing material which the
manufacturer provides is usually supplied in an
extra bag.
Before you install the device, take suitable precautions to protect air distribution components from
contamination during installation (VDI 6022). If this
is not possible, at least cover the devices or take
other precautions to protect them from contamination. In this case you have to ensure that the
devices cannot be activated. Ensure that the components are clean before you install them. If necessary, thoroughly clean them. If you have to interrupt
the installation procedure, protect all openings from
the ingress of dust or moisture.
Installation
Air terminal devices Slot diffusers, Type VSD...4
Ceiling installation
If possible, install the unit before fixing the ceiling
tiles; if this is not possible, remove the adjacent
ceiling tiles.
Use only approved and adequately sized suspension systems (fixing material is not included in the
supply package). Dimensions and weights are
given in the technical leaflets.
Only work in pairs; preferably use a lift.
Fig. 2: Plenum box
1. Fix the suspension parts such as ropes,
cables or metal hangers (Fig. 2/1) to the
ceiling.
2. Use all of the available suspension points on
the plenum box.
Slot diffusers, linear run
Fig. 3: Linking slot diffusers
3. The supplied connecting pins (
Fig. 3/1) or
alignment plates (
Fig. 3/2) (only connecting
pins for VSD15) help to align slot diffusers
for a continuous linear arrangement.
Insert a connecting pin or fix an alignment
plate (2 each per diffuser) on one side, then
connect the next diffuser to it.

End seal (tubular)
Continuous linear runs require an end seal on
each end to ensure that no air leaks
End seals can be either factory fitted or fitted
by others
Single diffusers require end seals on both ends
End seals are suitable only for slot diffusers
without extended border

Slot diffusers with concealed screw fixing
The face of slot diffusers with concealed screw fixing (variant AS or DS) can be fixed to the plenum box
after the false ceiling has been completed.

Air connection
The diffuser has a spigot to connect it to the
ducting. Variants with a double lip seal allow for a
sufficiently tight connection; additional sealing is not
required.
Commissioning, maintenance and cleaning
Initial commissioning
Before you start commissioning:
Check that the air terminal devices are cor-
rectly seated.
Remove protective films, if any.
Ensure that all air terminal devices are clean
and free from residues and foreign matter.
Check that electrical connections (if any) have
been correctly made.
Ensure that the device has been correctly fixed
and connected to the ducting.
For commissioning see also VDI 6022, part 1 – 'Hygiene requirements for ventilation and air-conditioning systems and units'.
Volume flow rate balancing
When several diffusers are connected to just one
volume flow controller, it may be necessary to balance the volume flow rates.
Slot diffusers with plenum box and damper blade
(variant -M): The damper blade can be adjusted
even after the diffuser face has been installed.

Cleaning agents that contain chlorine must not
be used.
Equipment for removing stubborn contamina-
tion, e.g. scrubbing sponges or scouring
cream, may damage the surfaces and must not
be used.
