Before installing the fire dampers, make sure that there are no damage, during
transport or storage, that could block the damper blade.
Check that the damper blade can be opened and closed (full opening and closing
position). To open fire dampers KWP-LE use the actuator key.
The opening and closing must proceed smoothly (not stepwise).
Do not pull by damper blade to open or close fire damper, it may cause permanent
damage, not covered by the warranty.
To opening fire dampers KWP-LS use a key, mounted on damper casing.
Before installing, secure the fire damper, by dust and dirt, using a foil or other
screening material. It can prevent components of fire damper by damage.

1.
Make an opening in the ceiling with the dimensions 120 mm greater than the nominal
dimensions of the fire damper, i.e. B+120 and H+120.
2.
Put the closed fire damper into the installation opening and support or suspend, in this
way that an axis of the fire damper blade matches the axis of the ceiling, and ensure a
concentricity of fire damper and mounting hole.
3.
After setting the fire damper as described, mounting the mounting brackets, fill the gap
between the fire damper and the ceiling with cement, cement-lime mortar or concrete.
4.
After the mortar has dried (about 48 hours), remove the supports or suspenions, check
the fire damper correct operation and leave it in open position.
