CONDITIONS OF TRANSPORT AND STORAGE
Fire dampers KWP-L should be stored in cardboard boxes and/or on pallets. KWP-LE should have a pre-protected
actuator cardboard box. Fire dampers should be stored indoors, providing protection against atmospheric agents, at a
minimum temperature of +5°C.
Do not allow mechanical damage of damper, that may be caused e.g. blows or dropping.
After each transport, visual inspection of each fire damper must be carried out.

INSTALLATION TECHNOLOGY
Before installing the fire dampers, make sure that there are no damage, during transport or storage, that could block
the baffle.
Check that the baffle 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 baffle 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.
To be able to preserve the declared resistance, insulation and smoke leakage EIS120, EIS90, EIS60, EIS30, dampers
should be installed on wall, which was classified as EIS120, EIS90, EIS60, EIS30.
The KWP-L fire dampers may also be installed in buildings partitions with a lower fire resistance rating. In this case,
the damper fire resistance rating is equal to the partition fire resistance rating, subject to the smoke leakage criterion.
Ducts made of flammable and non-flammable materials can be connected to the damper. Ducts should be installed
that they can not load the damper during fire. Ducts lengthening during fire can be compensated by support and knee.
ATTENTION: Distance between fire dampers or fire damper and construction elements must be compatible with
standard 1366-2:
a.
Minimal 200 mm between fire damper, which are installed in different ventilating ducts,
b.
Minimal 75 mm between fire damper and construction element (wall/ceiling).
