Preparing the GC
WARNING Hazardous voltages are present in the mainframe when the GC is plugged in.
Avoid a potentially dangerous shock hazard by unplugging the power cord
before removing the side panels.
1. Turn off the GC and unplug the power cord. Allow time for all heated
zones to cool and then turn off supply gases at their sources.
From the back of the GC (see the next figure):
2. Unsnap and lift off the pneumatics top cover.
3. Remove the RFI cover. Remove the screw with a T-20 Torx screwdriver,
slide the cover to the left until it disengages from the top rear panel, and
remove it.
4. If you are installing a nonEPC detector, remove the detector cover plate
from the front or back position by loosening the two screws with a T-20
Torx screwdriver and sliding the plate up and off.
