Remove the 15 sheet metal screws that hold the perforated cover in place and remove this along with the top rear plate cover. Save the screws in a safe place. Be careful not to remove the screw that supports the insulating spacer that shorts to ground the positive high voltage, for safety reason, when the top cover is removed. The photo shows the small isolating spacer tied up the cover.
