1 Safety
1.1 General safety notes
Sharp edges, sharp corners and thin sheet metal
parts
CAUTION!
Danger of injury from sharp edges, sharp cor-
ners 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.
Electrical voltage
DANGER!
Danger of electric shock! Do not touch any live com-
ponents! Electrical equipment carries a dangerous
electrical voltage.
– Only skilled qualified electricians are allowed to
work on the electrical system.
–Switch off the power supply before working on
any electrical equipment.
1.2 Correct use
The fire damper is used as an automatic shut-off
device to prevent fire and smoke from spreading
through ducting.
The fire damper is suitable for supply and extract air
in HVAC systems.
The fire damper may be used in potentially explo-
sive atmospheres if appropriate special accessories
are used with it and if the product bears the CE con-
formity marking according to Directive 94/9/EC. Fire
dampers for use in potentially explosive atmos-
pheres are marked for the zones for which they
have been approved.
Operation of the fire dampers is allowed only in
compliance with installation regulations and the
technical data in this installation and operating
manual.
Modifying the fire damper or using replacement
parts that have not been approved by TROX is not
permitted.
If this fire damper is used in Germany:
Do not use it in extract air systems in commercial
kitchens.
Not to be used as an air transfer damper.
Do not use in combined penetration seal.
Do not use in fire protection block bulkhead.
Approvals under building regulations may be
required for the use of upstream shutters for air
transfer units. This must be checked and applied for
by others.
Flame-resistant, non-dripping building materials
(elastomeric foams) must at least correspond to fire
rating class C - s2, d0 according to the specifica-
tions of MVV TB (since 2019/1). The applicable local
building regulations must be observed.
Incorrect use
WARNING!
Danger due to incorrect use!
Incorrect use of the fire damper can lead to dan-
gerous situations.
Never use the fire damper
–without specially approved attachments in areas
with potentially explosive atmospheres
– as a smoke control damper
– outdoors without sufficient protection against the
effects of weather
– in atmospheres where chemical reactions,
whether planned or unplanned, may cause
damage to the fire damper or lead to corrosion

3 Supply package, transport
and storage
Supply package
If attachments and accessories are supplied from the
factory with the fire dampers, they are already taken into
account in the order code.
Depending on the installation situation, supplementary
materials for assembly and fixing may be needed to
ensure proper installation, e.g. mortar, screws, mineral
wool, etc.
Such materials are not included in the supply package,
unless they are expressly described as included in the
supply package.
The selection of additional attachments or accessories
as well as the identification and provision of materials
for assembly and fixing is the responsibility of those
involved in the building project and must be done taking
into account the required classification.
Delivery check
Check delivered items immediately after arrival for
transport damage and completeness. In case of any
damage or an incomplete shipment, contact the ship-
ping company and your supplier immediately.
Fire damper
– Attachments/accessories, if any
Operating manual (1 per shipment)
Colour hues on the damper blade
The blades of fire dampers are treated with a
greenish impregnating agent. Resulting colour hues
on the damper blade are due to technical reasons
and do not constitute a defect of any kind.
Transport on site
If possible, take the product in its transport packaging
up to the installation location.
Bearing
For temporary storage please note:
Remove any plastic wrapping.
Protect the product from dust and contamination.
Store the product in a dry place and away from
direct sunlight.
Do not expose the unit to the effects of weather (not
even in its packaging).
Do not store the product below -40 °C or above 50
°C.
Packaging
Properly dispose of packaging material.
