Note Keep all manifold parts you remove covered on a clean work surface so they will not
accumulate dust.
10. Disconnect the filament board and wires from the source interface board.
11. Remove the bottom left screw holding the metal heat shield to the manifold.
12. Remove the heat shield and wedge it between the source interface board and the wall of
the manifold to disconnect the board from the 20-pin feedthrough.
13. Remove the bottom right screw holding the tray to the manifold.
14. Detach the reagent gas and calibration gas tubes from the gas mixing chamber and
remove from the manifold.
15. Move the large tab on the analyzer tray to the left, moving the ion source away from the
transfer line, and then carefully pull the tray toward you through the manifold door.
CAUTION - INSTRUMENT DAMAGE Do not scratch any of the sealing surfaces. Be
especially careful when the source interface board reaches the o-ring surface.
