so you got the CS-X3 unit (the rectangular one)? If so, you just take the plastic wrap off of the insert, adjust the little slider on the top of it to open or close the slits, and then put it inside of the plastic housing. that's all there is to it. the smell is pretty strong, so if you can't smell it then there's definitely something wrong.
