I have installed everything correctly.
Also pulled the protective film from the red plastic.
But even then it smokes a bit at the part where the fan is installed.
Does someone had this problem as well and / or knows how to fix this?
I don’t have the PRO with the rigid enclosure, but I got the “soft” enclosure separately when I bought my 22W Falcon. In my case, the fan on the enclosure is way too weak to be usefull.
Also, make sure there is a way for the air to enter if you want proper air flow - what goes out needs to be able to come in some way. This being said, I don’t know how your encolsure is built, so I can’t really say that is the issue.
Can you try to trace it with a flashlight where light shines through to find any gaps?
Mine does not have this problem, so it should be possible to get it air tight there.
