Need help cleaning filter

[AV8TOR]

I have an Aquatech FNS-48 DE filter and as I took over this home I never had equipment manuals. Am I supposed to be able to lift this assembly out of my filter? Or do I have to remove the two screw and remove the black plastic top cover and remove all plates individually?I have been just hosing this clean as it sits and collecting the junk from the drain. Thanks in advance

I don't know how that comes apart, but I clean mine the way you've been doing yours. Unless you think you need an acid wash, I see no reason to remove them.
