The appliance is constructed and 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 +50°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 +50°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.
Flange and screw joints must be conductively connected to protect against dangerous contact. 2
galvanized fan shape pads that are placed under the head of one screw and a fastened nut are
used for conductive connection.
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.
Manual operation
Without power supply, the damper can be operated manually and fixed in any required
position. Release of the locking mechanism can be achieved manually or automatically
by applying the supply voltage (design 4Mx or 5Mx).
Assembly, maintenance and damper function check can be done only by qualified and trained
person, i.e. “AUTHORIZED PERSON” according to the manufacturer documentation. All works
done on the fire dampers must be done according international and local norms and laws.
