  1. Shorten the inner sound insulation element by the same dimension used before for the wall sleeve.

  1. Place the storm protection in the sound insulation element approximately in the middle.

The storm protection is already fitted in the centre ex-works. With the sound insulation element shortened, move the storm protection approximately to the middle. Ensure that the installation position is vertical. The silicone slats must not hang down under their own weight. If you remove the storm protection completely, make sure that the “UP” arrow is still pointing upwards when you put it back in.

  1. Push the sound insulation element into the wall sleeve from the inside.
