Other risk
When the product is voltage fed, the damper will be
either open or close and there can be a certain risk
for pinch injuries, for example, on the fingers if these
are placed between the damper blade and ventilation
duct when the damper blade rotates. The product’s
actuator is equipped with a release button that permits
manual control of the damper blade, always ensure this
is activated before working on the internal parts of the
damper.
If the product is equipped with a spring return actuator there is
no release button, manual control is performed using the sup-
plied hex key where the damper blade is cranked to the required
position and then locked. Do not forget to disable the lock after
working on it.
