Maintaining the Mainframe
The mainframe consists of everything that does not fit in the vacuum,
analyzer, interface, or electronics categories.
To remove the MS covers
Materials needed
• Screwdriver, Torx T-15 (8710-1622)
If you need to remove one of the MS covers (see Figure 4), follow these
procedures:
To remove the top cover
Remove the seven screws and lift the cover off.
To remove the front right analyzer window cover
1 Pull out from the top of the window and forward from the bottom. The
cover is held in place by magnets.
2 Lift the window forward and off the MS.
To remove the front bottom cover
Grasp the cover on both sides and pull the cover forward.
To open the left side panel
1 Remove the front right analyzer window.
2 Pull gently on the front left window and allow the left side panel to swing
forward and down.
The GC/MS interface, the analyzer parts, and the vacuum system operate at
temperatures high enough to cause serious burns. Give these parts enough time to
cool before accessing them or handling them.
