General Maintenance 4
Troubleshooting and Maintenance Manual 111
Reinstallation
1 Unpack the new source heater assembly (G3170-60177). The heater,
temperature sensor, and heater block are already assembled.
2 Reinstall the repeller, repeller insulators, washer, and repeller nut
(Figure 13). The resulting assembly is called the repeller assembly.
3 Connect the repeller assembly to the source body with the two screws and
washers.
4 Reinstall the filaments.
5 Reinstall the ion source in the analyzer chamber.
6 Reconnect the wires from the feedthrough board to the ion source.
7 Reconnect the heater and temperature sensor wires to the feedthrough
board.
8 Close the analyzer chamber.
9 Pump down the MS. See the Agilent 7000 Series Triple Quad GC/MS
Operation Manual.
Always wear clean gloves to prevent contamination when working in the analyzer
chamber.
Do not overtighten the repeller nut or the ceramic repeller insulators will break when
the source heats up. The nut should only be finger-tight.
The analyzers, GC/MS interface, and other components in the analyzer chamber
operate at very high temperatures. Do not touch any part until you are sure it is cool.
Make sure you use an antistatic wrist strap and take other antistatic precautions
before touching analyzer components.
