7. TRANSPORT AND STORAGE CONDITIONS
Fire dampers are packaged in cardboard boxes or placed on pallets. Dampers are protected against damage by film
or another covering material. Damper shipping may take place using any means of transport, under the condition
they are protected against weather factors. Dampers placed on means of transport should be secured against shifting
of position during transport. Before installing dampers, control each of them visually. Do not move the damper by
holding by the connection cable or put a device on a release and control mechanism. Do not hit or drop the damper.
When moving and installing, support the damper on the sides or edges of the body.
Dampers should be stored in closed rooms that provide protection against external weather conditions. In the case
dampers are stored on the ground, place them on protection pads in order to protect them against damage. Storage
should take place in rooms where:
• there is no access to dust, gases, caustic vapors and other aggressive chemical vapors that can destroy
insulating elements and structural elements;
