Agilent 7820 GC Service
Hazardous voltages are present in the
mainframe when the GC power cord is connected.
Avoid a potentially dangerous shock hazard by
disconnecting the power cord before removing
any GC panels.
Components can be damaged by static electricity:
be sure to wear an ESD strap grounded to the GC
chassis while performing this procedure.
Disconnect all attached electrical connections to the FPD board.
Turn thumb screw counterclockwise, lift screw to disengage,
slide board down, and then lift out. (Note that the grounding point
for the board is at the thumbscrew).
Replace board if required. (Note that the FPD board is longer
than the FID board and is attached to the full length of the GC
board receptacle.)
Replace connections in reverse order of disassembly.
Reconfigure the modified GC from the software keypad
supplying requested information.
