Mounting instruction for actuators size M on air dampers
Specification
Actuators size M are equipped with a 16 × 16 mm (double square) shaft connection. The form-fitting shaft connection is the securest connection between damper shaft . The actuator
will be connected firmly by means of four screws M 8 × 140 mm (scope of supply) to the damper.

For damper shafts 14 × 14 or 12 × 12 mm reducing bush are optional available.
Mounting instructions form-fitting shaft connection
It is to be considered that the actuators have a total angle movement of approx. 95° in
order to realize a pre-tention on the damper. Therefore the actuator sits tilted on the
damper shaft. In order to prevent this and to assure pretention to the damper the driving
shaft has to be adjusted mechanically before connecting to the damper shaft.
The provided socket wrench serves for the mechanical adjustment over the hand-operated
control socket HV. The actuators are axially symmetrically developed. In case of spring
return function the safety postion must be selected by turning the actuator 180°.

Mounting:
1. Affix tap hole M8 (in accordance with drill template) on the damper or to a mounting
bracket.
2. Adjust drive shaft of the actuator with the socket wrench that the drive stands
perpendicular to the damper before pluging actuator on to the damper shaft.
3. Plug actuator onto damper shaft and fix diagonally with 2 screws.
4. Remove the socket wrench.
5. Pivot and tighten the remaining screws.
Note: the drive shaft is selflockingly produced and may only be mechanically adjusted
either with the provided socket wrench or the optional accessory „HV-M" manual override.
External applied force to the shaft can lead to mechanical damage of the actuator.
