Turning connection

This is an optional procedure to attach the sound-insulation distributor to the WS 120 Trio symmetrically or more adapted to the environment:

  1. Loosen the 6 screws on the connection flange.
  2. Remove the connection flange and turn it 180° at the duct flange.
  4. Refit the connection flange in the new position.
  6. The sound-insulation distributor can now be mounted symmetrically.
