Mini Advent II Inddor and Outdoor models

If you could show me how to open those up I’d be a friend for a few days. Or where I can find a video.

@FlakaSeaguls Sorry, for some reason I never got a notification for this comment. You have probably figured it out already, but you have to find a flat and wide tool to pry on the corner of the front grill. Pry from the side at one corner while applying pressure on the front of the grill, and it should start to pull off. The grill is not held on by glue or anything, it's just bent and held into a slot by friction. Once it comes off you can unscrew the outer screws on the baffle which will open up the cabinet.
