Agilent 7820 GC Service
25
Inlets, detectors, and the oven are insulated
with fibrous materials which may cause
irritation to skin, eyes, and/or mucous
membranes. Always wear gloves when working
with the insulation. Additionally, if the
insulation is flaky/crumbly, wear protective
eyewear and a suitable breathing mask and/or
respirator.
Inside the oven, remove interferences as needed: column(s), the
inlet insulating cup, and so forth.
Remove the split/splitless top weldment assembly. See
Replacing the split/splitless inlet top weldment assembly (
26).
At the top of the GC, remove screws from the injection port top
cover and remove the cover to expose the inlet assembly.
Disconnect the split vent line.
Disconnect the sensor/heater cable and work it back through any
interfering wiring, tubing, and/or GC frame members.
Remove 3 screws to release the inlet body assembly with its
insulation and cup and lift the assembly from the GC.
