Thank you very much for the details! Finally I was able to remove the top cover: I started to pull it and after several minutes it suddenly popped out of the groove! Next challenge was the black rounded cover, on this one I forced too much and the thinner part of the larger clip broke but it doesn't compromise the whole cover.
The pre filter support has a tight fit, maybe I didn't aligned it correctly on the pins and it needed some effort to fit into the right place.
The top cover was again a P.I.T.A but since it entered correctly on the groove everything went well. For the DIY guys it can be easier but is not my case lol
I would like to thank you for your patience to detail all these steps, Sandman!
