8. The function testing of the motorized model can be performed
de-energized by means of the hexagon wrench delivered with
the product, and energized by using the switch of the thermal
trip. Note! If you open the damper with the hexagon wrench,
be sure to release the damper back to the closed position
before switching on the current.
9. Connect ducts to the damper according to the instructions
provided by the designer or manufacturer. Each damper is
equipped with a flange joint.
10. The fastening of the fire damper must have a fire resisting ca-
pacity that is at least as high as the fire classification of the
penetrated building element (the fire resistance rating of a
class EI 60 element is
R 60, etc.).
11. If the fire damper is used as an air transfer or air terminal de-
vice, it must be equipped with a protective grille. The distance
between the grille and the damper blade in the open position
must be at least 30 mm. In case of large fire dampers, an
extension piece must be installed between the grille and the
damper blade.
12. Only a trained electrician is allowed to perform the electrical
wiring according to separate drawings and wiring diagram.

1. Firstly, mount the installation frame ER2 into the fire-separat-
ing building element. Make sure that the wider flange of the
frame is on the side of the fire damper. Make sure that the
frame is mounted into the correct position, so that the actua-
tors of the fire damper end up on the intended side of the
building element.
2. The dimensions of the building element penetration must be
at least: bxh =(B+80mm) x (H+80mm).
3. Insert the frame ER2 into the penetration.
4. Cast in the gap throughout the thickness of the building ele-
ment. Use incombustible, rock-based, fine-grained gypsum or
concrete. Protect the damper for the time of casting.
5. Place the fire damper inside the frame and fasten it by using
the fixing plates and bolts delivered with the damper.
6. Check the functioning of the fire damper and proper mov-
ing of its blade. Clean the damper, if necessary. Place plastic
covers on the openings and keep them covered, until ducts
are connected to the damper.
7. Tensioning the spring of damper with thermal fuse: Turn the
blade into the open position, until you hear the retaining clip
snap. After this, you can check the closing function of the
damper by pressing the red testing lever.
