The appliance is constructed and preset by the manufacturer, its operation is dependent on
proper installation and adjustment.
Dampers are transported by box freight vehicles without direct weather impact, there must not
occur any sharp shocks and ambient temperature must not exceed +40°C. Dampers must be
protected against mechanic damages when transported and manipulated. During transportation,
the damper blade must be in the "CLOSED" position.
Dampers are stored indoor in environment without any aggressive vapours, gases or dust. Indoor
temperature must be in the range from -30°C to +40°C and maximum relative humidity 95 %
(avoid condensation on the damper body). Dampers must be protected against mechanic
damages when transported and manipulated.
All effective safety standards and directives must be observed during fire damper assembly.
The damper body should not be deformed in the course of bricking in. Once the damper is built
in, its blade should not grind on the damper body during opening or closing.
To ensure reliable fire damper function it is necessary to avoid blocking the closing mechanism
and contact surfaces with collected dust, fibre and sticky materials and solvents.
