Help to disassemble

[welderwonder]

Hello,

DIY homeowner,

I have a DANBY DPAC 120068 portable AC cooling unit.  I want to clean the cooling unit, but access means removing all visible screws.  After I removed these screw, I tried to separate the front and rear covers.  No success and I don't want to force and probably cause damage.  There seems to be some obstacle to it separating.

Does anyone have a service document that shows the cooling unit as an exploded parts view document?

Thank you
