Safety notes
!
• The actuator is not allowed to be used outside the specified field of application, especially in
aircraft or in any other airborne means of transport.
• It may only be installed by suitably trained personnel.
All applicable legal or institutional installation regulations must be complied with.
• The cover of the protective housing may be opened for adjustment and servicing. When it is
closed afterwards, the housing must seal tight (see installation instructions).
• The device on the inside may only be opened up in the factory. It does not contain any parts
that can be replaced or repaired by the user.
• The cable must not be removed from the device.
• 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.
• The device contains electrical and electronic components and is not allowed to be disposed
of as household refuse. All locally valid regulations and requirements must be observed.

Safety notes (continued)
• The information on chemical resistance refers to laboratory tests with raw materials and
finished products and to trials in the field in the areas of application indicated.
• The materials used may be subjected to external influences (temperature, pressure,
constructional fixture, effect of chemical substances etc.), that cannot be simulated in
laboratory test or field trials.
• The information regarding areas of application and resistance can therefore only serve
as a guideline. In case of doubt, we recommend that you definitely carry out a test. This
information does not imply any legal entitlement. Belimo will not be held liable and will
provide no warranty. The chemical or mechanical resistance of the materials used is not
alone sufficient for judging the suitability of a product. Regulations pertaining to combustible
liquids such as solvents etc. must be taken into account with special reference to explosion
protection.
