To remove the Cooling Tray Base, the left side panel (when facing the front of the machine) must be removed. This is the side that DOESN'T have the control panel. There are two screws hidden behind the two rubber lugs as indicated in this picture. Use a suitable tool and pry the plugs out. The backside of the plugs is coated with a sticky substance that keeps them in place. Put them aside in a clean environment so as not to pollute the adhesive.
Remove the two screws behind the plugs and the side panel can be pulled away from the machine, freeing the Cooling Tray Base from the machine. The arrow indicates the slot and tab that held the Cooling Tray Base in place. Slide the Tray Base out of the machine.
When replacing the Cooling Tray Base, be sure to engage the tabs seen in step two, as well as the tabs that locate the side panel onto the machine.
Replace the screws in the following steps, but do not tighten.
a - Verify that the tabs on the Cooling Tray Base are properly engaged.
b- Replace the Base and verify that the various mounting tabs of the Side Panels are properly engaged with the base and metal framework.
c - Replace the Rear Cover.
Verify that all panels have been properly aligned, then tighten the various screws while holding the parts in alignment.
