Well it looks like the filter (#26) is under the cover (#29).
You need to look at the cover to see how it is held on, I can't tell from
the diagram.
Remove the 4 main case screws (15) at the corners to remove it. Note there
are 4 that actually hold it and a few that hold other parts.
Lift cover far enough to get to the screw that holds the filter
Remove screw and slide cover forward.
Mind you it's a best guess based on what I can see from the dia,
