MOUNTING
In opened position the blades do not overhang
the housing of the damper. Any part of the
element (ex. grid louver) connected to the
damper should not overhang in the housing of the
damper in order to not obstruct the free
movement of the blades. The
BSK-J/EI90
multi-
blade
fire
dampers can be built in independent
from the access direction of the motor. There is no
need of separately right or left hand version.
The servomotor is shipped with a connection
cable (approx. 1 m long, with free ends). The
servomotor is equipped with protection casing in
order to prevent damages. The thermal relay can
be fixed on the optionally ordered extension or on
the ductwork built before or after the damper.
It is
FORBIDDEN
to make a hole on the housing of
the damper in order to place the sensor!
Take care to avoid damages. If the connecting
surface is not flat or the connecting frame is not
rectangular, the damper can be stretched. When
installing even connecting surfaces and
perpendicular edges must be assured. After
installing the easy move must be controlled. T
he
damper must be installed with closed blades.
The contact with splashing or running water must
be avoided, therefore it must be protected (ex.
outdoors must be fitted with a protective roof
against rainwater). The special fireproof material
of the damper absorbs moisture. In case of
excessive moisture the material gets soft, cracks
can appear. These can cause the damage of the
damper.
If the damper gets wet after drying it can be
operated without any problem. The water
resistance can be increased if we coat the
fireproof insulation parts of the damper with
PROMAT 2000 impregnating material.
