Removing the rear covers
There are two covers on the rear of the 6890 GC. The top cover shields the
EPC board and any inlet, detector and auxiliary pneumatics modules. The
bottom cover shields the oven fan motor, oven damper, the transformer and
the AC power board.
Removing the top rear cover
1. Remove the plastic pneumatics top cover and the metal RFI shielding
cover over the auxiliary and detector pneumatic slots as described in this
section.
2. Loosen the four Torx T-20 screws on the top, rear cover.

the cover down and away from the GC. Carefully guide any installed inlet
plumbing out of the slots in the top of the cover.
