Install the wall cover panels

Install the wall cover panels (4 pcs) with 4x30 screws (8 pcs each).
Note: Make sure that the grooves in the panels are on the outer edge of the panel. Use the existing screw holes.
Note: If you install for the first time, you need two extra screws per panel, in addition to the ones removed at the beginning of the installation. Install the two additional screws to the two vacant countersunk holes in the cover panels.
