100 5977B Series MSD Troubleshooting and Maintenance Manual
4 General Maintenance
4 The foreline pump may be located on the floor, on the lab bench next to or
behind the MSD, or under the analyzer chamber at the back of the MSD.
Move it as needed to provide slack in the tubing and cables.
5 Slide the MSD backwards, and then away from the GC until you have
access to the GC/MSD cables. (See Figure 6.)
6 Disconnect the GC/MSD interface heater cables, and the LVDS cable.
Disconnecting the interface heater cables with the GC on can cause a fault
condition.
7 Continue to move the MSD until you have access to the part requiring
maintenance.
