13. Assembly
13.1.
Assembly, maintenance and damper function check can be done only by qualified and trained person, i.e.
“AUTHORIZED PERSON” according to the manufacturer documentation. All works done on the fire dampers must be
done according international and local norms and laws.
13.2.
All effective safety standards and directives must be observed during damper assembly.
13.3.
To ensure reliable smoke exhaust damper function it is necessary to avoid blocking the closing mechanism and
contact surfaces with collected dust, fibre and sticky materials and solvents.
13.4. Manual operation
Without power supply, the damper can be operated manually and fixed in any required position.
13.5.
For electrical connection of the actuator use the prefabricated slot in the protection boxon the top side of the box.
13.6.
If it is necessary to use other position of the connecting holes, then make two holes to the protection boxto pull in
connecting cables (heat resistant cables) to the cables of damper´s actuator. Protection boxis made of calcium silicate
plates.

maintenance and revisions
12. Logistic terms
12.1.
Dampers are delivered on a pallets. Another required packaging system should be approved and agreed by manufac-
turer. Packaging material is not returnable in case that another packaging system ( material ) is required and used and it is not
included into final price of damper.
12.2.
For unloading and further manipulation with the damper is necessary to use appropriate tooling ( forklifts ) due to
damper weight. Dampers are fragile.
12.3.
Dampers are transported by boxfreight vehicles without direct weather impact, there must not occur any shocks and
ambient temperature must not 50°C. Dampers must be protected against mechanic damages when transported
and manipulated. During transportation, the damper blade must be in the "CLOSED" position.
12.4.
Dampers are stored indoor in environment without any aggressive vapours, gases or dust. Indoor temperature must be
in the range from -30°C to +50°C and maximum relative humidity 95 % (avoid condensation on the damper body). Dampers
must be protected against mechanic damages when transported and manipulated.
Fig. 50 Connecting holes
Procedure
• use drill
Ø
10 and make two holes (see fig. 50). It is possi-
ble to make 2 holes in any wall of the box.
• pull the heat resistant cable through the calcium silicate
plate (wall) and connect with cables from actuator
according to above mentioned electrical diagram.
• seal up the space in the hall with fire resistant mastic or
sealant
• let the sealant harden
