Transport and delivery
The transport is performed by common transport means. Components that are free loaded should be
secured in such a way that any deformation and damage to the components will be eliminated. The trans-
port vehicle must be covered to prevent dust, debris and humidity to damage the components.
Components are delivered without an acceptance at a supplier´s as default. If an acceptance at a
supplier´s is required, it is necessary to state this requirement in the orderpurchase contract.
A buyer or his/her representative is obliged in terms of good acceptance to on site check these according
to the delivery documentation. Visible defects and amount shortages are to be noticed in the transporter’s
transport sheet immediately.
Storage
The goods should be stored inside and protected to prevent dust, debris and humidity to damage the
goods.
Before mounting
Before starting the mounting of the damper it is necessary to inspect all components to make sure that
they are correct according to the project documentation and to make sure they have not been damaged
during transport or storage. When handling the products on site it is important to be careful so that they
don’t get damaged and their properties change.
Mounting of the damper should only be done by trained professionals equipped with the correct protec-
tive equipment and tools. The mounting of the damper should always be performed according to valid
documentation from the manufacturer.
The damper should never be used as a supporting part of the building.
In order to achieve a good result, ensure you have:
• A well-organised and protected storage site for components and other parts that are to be assemb-
led.
• A properly planned assembly sequence in accordance with the instructions.

Preparations:
• Cut ducts at right angles.
• Carefully remove any burrs from cut edges. Installation is
easier and the risk of damaging the gasket is reduced if there
are no burrs.
• Cut away the needles created from the fold.
Assembly
• Start by inserting the turned-over edge of the damper into
the duct.
• Check that the  rst lip of the gasket is in contact with the
edge of the duct all the way around and sticks straight out so
that the lip is not twisted in one direction or the other.
• Push the end of the damper into the duct. Twisting the
damper slightly aids insertion.
• Secure the damper in the duct using self-tapping screws
Ø4,2×13.
• Fasteners should be positioned on the duct close the damper
(minimum 10-15 mm) to support itself weight and to prevent
damage to the gasket.
• The damper must be installed on certi ed and CE marked
smoke control system.

Electric cables and system
For Manual Activation version (MA), the electric cables and system must be protected and designed to
have at least 30 minutes circuit integrity.
Operation
All smoke dampers have a electrical actuator. They are designed to be installed indoor in a smoke evacua-
tion and reversable HVAC system.
Before starting the system it is necessary to check the system for damages and that it is consistent to the
re expert design.
Checking and Maintenance
Following features shall be checked up during a revision of the damper at least once every six months:
• All parts are to be installed according to this mounting instruction.
• The damper must not be damaged in any way, the cross-section of the casing, the motor and the
covering box of the motor must not be damaged in any way.
• All connections with the smoke evacuation system are to be tightened and properly connected.
• The ducts connected to the damper must be suspended or supported in order to bear the damper’s
weight too.
• There must not be any ammable bodies on the damper surface and 50 mm away from the system
itself.
Periodic inspection and cleaning
Periodic inspection shall be performed in accordance with the requirements of the law or by the building
regulations or other local regulations.
In the absence of specic regulations (or to their complement), in accordance with point 8.3 of the EN
12101-8 standard, it is recommended to carry out the following controlactivities at intervals of no more
than 6 months: execute an opening and closing test and check the correct movement of the blade and the
correct functioning of the microswitches (limit switches). Blade opening time shall be not more than 60
seconds. Blade closing time shall be not more than 60 seconds.
Together with the control activities, it is recommended to visually verify the absence of corrosion, the
integrity of the electrical wiring and the sealing of the construction support. Damper cleaning is included
in the ordinary maintenance activities of the ventilation ducts. Smoke control dampers can be cleaned
with a dry or wet cloth. In the case of resistant dirt, it is possible to use normal household detergents. If
prescribed for the type of building, it is possible to use disinfectant detergents. The use of detergents or
mechanical abrasive cleaning systems is not permitted. These indications comply with the standards EN
12101-8 annex B and EN 15423 annex C.
