In the name of spitballing and with admitting to no true knowledge?
I look at the parts drawings and see what "might/could/maybe" be clips that hold a front section to a back section?
Several unknown things but thought to point to what they show us and maybe it gives you a place to look for a plan?
Are these clips as marked that might release the front with motor and fan from the back, letting it slide up enough to clear the floor?
It looks like five total but I may be missing some, so approach with care!
These should show locations of something that looks like clips that might be flipped off---if there is room? Pictured clockwise, starting at about two o'clock ?
Click these snips for better picture!
