KWP-O-ES
INSTALLATION TECHNOLOGY
Prior to the installation, fire dampers should be checked whether there has been no damage to the dampers during
transportation or storage..
Check whether the damper baffle could be opened and closed (fully open and closed position). To open fire dampers
KWP-O-E use the actuator key.
The full opening and closing must proceed smoothly (not stepwise).
You must not pull by baffle to open or close fire damper, it could cause lead to permanent damage, not covered by the
warranty.
While testing KWP-O-S open it by key, placed on the damper.
The damper must be protected with covering material before montage, so it will be protected from soiling, and
consequently damaging the elements of the damper.
ATTENTION: Distance between fire dampers or fire damper and construction elements must be compatible with
standard 1366-2:
Minimal 200 mm between fire damper, which are installed in different ventilating wires,
Minimal 75 mm between fire damper and construction element (wall/ceiling).
Before installing fire dampers please read assembly technology recommended by the manufacturer. The way of
installing recommended by one manufacturer may not be the same for other dampers. Recommended material and
dimensions of the openings follow from experience from conducted research. In rectangular dampers, most of all
dampers with cross-sectional area more than 1 m2, it is recommended to use mounting wedge and spreader securing
the housing against squeezing during assembly.
Squeezing the housing can change the dimensions of slot between baffle and housing, correct dimensions of this slot is
needed to keep correct way of opening and closing the damper. Correct preparation of the damper for the installation
is presented on the figure 3 and 4.
