 To reinstall the vacuum manifold's top cover
1. Remove and discard the tissue from the vacuum manifold's top opening.
2. Check the vacuum manifold's split chamber O-ring for signs of wear, and replace it if
necessary. Enure that the O-ring is positioned properly.
3. Carefully lift the top cover plate up by its two handles and turn it over.
4. Orient the top cover plate so that the one or two electron multipliers, as applicable, are
over the conversion dynodes.
5. Carefully insert the four guide posts on the bottom of the top cover plate into the holes in
the vacuum manifold.
6. Hold the top cover plate parallel to the opening in the vacuum manifold and carefully
lower it onto the opening in the vacuum manifold.
CAUTION Do not damage the O-ring or the components on the bottom of the top
cover plate.
7. Reconnect the following:
• Three cables to the top cover PCB
• One or two electron multiplier HV coaxial cables, as applicable
• One electrometer cable
