To Move or Store the MSD when Connected to a 9000 GC
Materials needed
• Ferrule, blank (5181-3308)
• Interface column nut (xxxxx-xxxxx)
• 7/16-inch open-end wrench
Procedure
1 Separate the MSD and the 9000 GC. (See “To Separate the MSD from the
9000 GC” on page 99.)
2 Install a blank ferrule and interface column nut.
3 Tighten the vent valve.
4 Open the analyzer cover.
5 Finger-tighten the side plate thumbscrews. (See Figure 8 on page 106.)
6 Plug the MSD power cord in.
7 Switch the MSD on for 5 minutes to establish a rough vacuum.
8 Switch the MSD off.
9 Close the analyzer cover.
10 Disconnect the LAN, remote, and power cables.
Do not overtighten the side plate thumbscrews. Overtightening will strip the threads in
the analyzer chamber. It will also warp the side plate and cause leaks.
