•t The actuator is not allowed to be used outside the specified field of application, especially in
aircraft or any other form of air transport.
•t Assembly must be carried out by trained personnel. Any legal regulations or regulations
issued by authorities must be observed during assembly.
•t The device may only be opened at the manufacturer‘s site. It does not contain any parts that
can be replaced or repaired by the user.
•t When calculating the required torque, the specifications supplied by the damper manufactur­
ers (cross section, design, installation site), and the air flow conditions must be observed.
