Is there anything complicated about removal of this unit? What's the step-by-step procedure for removal? There are only 3 screws that attach the unit to the main frame, but are there any other attachment points, like springs, that would complicate its removal for a thorough cleaning? The exploded view in the manual shows all the parts but does not show if it is attached somewhere else, except for the 3 screws at the frame.
Thanks,
Steve.
