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.
Correct use
Air terminal devices are used for the ventilation of
internal spaces 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 tem-
perature differences).
Installation, operation and maintenance may have
to meet increased hygiene requirements for certain
areas of application.
Installation in humid rooms, areas with potentially
explosive atmospheres or rooms with dust-laden or
aggressive air has to be assessed beforehand
because it depends on the actual conditions on site.
Qualified staff
Specialist personnel
Specialist personnel are individuals who have suffi-
cient professional or technical training, knowledge
and actual experience to enable them to carry out
their assigned duties, understand any potential haz-
ards related to the work under consideration, and
recognise and avoid any risks involved.
Personal protective equipment
Personal protective equipment must be worn for
any work in order to reduce health or safety haz-
ards to the minimum.

General information
Personnel:
Specialist personnel
Protective equipment:
Industrial safety helmet
Protective gloves
Safety shoes
Note:
Fix the product only to load-bearing structural
elements.
Load suspension systems only with the weight
of the product. Adjacent components and con-
necting ducts must be supported separately.
Use only approved and adequately sized fixing
material (fixing material is not included in the
supply package).
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 product, take suitable precau-
tions to protect air distribution components from
contamination during installation (VDI 6022). If this
is not possible, at least cover the product or take
other precautions to protect it from contamination.
In this case you have to ensure that the product
cannot be started. Ensure that all components are
clean before you install them. If necessary, clean
them thoroughly. If you have to interrupt the installa-
tion procedure, protect all openings from the
ingress of dust or moisture.
Safety notes regarding installation
CAUTION!
Risk of injury due to incorrect installation.
A ventilation grille can weigh up to 25 kg,
depending on size and attachments. If it falls
down, there is a high risk of personal injury or
damage to property. Make sure it cannot fall
down. Take suitable precautions.
If you install it at height or in the ceiling, be sure
to choose a suitable fixing type (screw fixing)
and, if necessary, take additional safety meas-
ures to prevent it from falling down.

Initial commissioning, maintenance and
cleaning
Initial commissioning
Before you start commissioning:
Check that the grilles are correctly seated.
Remove protective film, if any.
Ensure that all grilles are clean and free from
residues and foreign matter.
Ensure that the devices have been correctly
fixed and connected to the ducting.
For commissioning see also VDI 6022, part 1 – 'Hy-
giene requirements for ventilation and air-condi-
tioning systems and units'.
Volume flow rate balancing
When several grilles are connected to just one
volume flow controller, it may be necessary to bal-
ance the volume flow rates.

Maintenance and cleaning
Please note:
The cleaning intervals given in the VDI 6022
standard apply.
Clean surfaces with a damp cloth.
Use only common household cleaners, do not
use any aggressive cleaning agents.
Do not use cleaning agents that contain
chlorine.
Do not use equipment for removing stubborn
contamination, e.g. scrubbing sponges or
scouring cream, as it may damage the sur-
faces.

Ordering replacement filters
To ensure permanent protection from particulate
matter and other pollutants we recommend using
only original TROX filters.
Filter medium FMP-G4-C11, coarse dust filter to
EN779, classification G4, ISO 16890: Coarse 55%
To avoid downtime of the ventilation and air con-
ditioning system, we recommend you to always
have the required filters in stock.
