extract air system (by others), which is typically
connected to an air handling unit.
Important notes
Air terminal devices Ceiling diffusers2
Air terminal devices supply cold or warm air to
rooms (within the stated supply air to room air temperature dif
ferences).
Installation, operation and maintenance may have
to meet increased hygiene requirements for certain
areas of application.
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.

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 air terminal devices must remain acces-
sible 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 all components are clean before you install them. If necessary
, clean them thoroughly. If you have to interrupt
the installation procedure, protect all openings from
the ingress of dust or moisture.
Ceiling diffusers
If possible, install the device 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.

Installing the diffuser face
In order to protect the surface of the diffuser face,
unpack and install it only after all other construction steps have been completed.
If there is a lengthy break between installation
and commissioning, cover all openings of the
casing (e.g. with plastic) to protect the interior
and avoid cumbersome cleaning procedures at
the time of commissioning.
Fig. 9: Installing the diffuser face
1. Glue the seal (Fig. 9/5) onto the reverse
edge of the plenum box.
2. Fix the dif
fuser face (Fig. 9/2) with the central fixing screw (Fig. 9/3) to the cross bar
