80 Troubleshooting and Maintenance Manual
4 General Maintenance
3 The foreline pump may be located on the floor, on the lab bench next to or
behind the MS, or under the analyzer chamber at the back of the MS. Move
it as needed to provide slack in the tubing and cables.
4 Carefully pull the GC away from the MS until you have access to the
GC/MS interface cable (Figure 11). The GC is guided as it slides by the
spacer bracket underneath both instruments.
5 Disconnect the GC/MS interface cable. Disconnecting the cable with the
GC on can cause a fault condition.
6 Continue to move the GC until you have access to the part requiring
maintenance.
