3 Maintenance and Troubleshooting
Do not to scratch the metal surface of the chamber cap. Scratches could result in an
imperfect seal.
2. Clean the groove in the chamber cap using a small brush or clean, lint-free tissue
moistened with isopropyl alcohol.
3. Allow the chamber cap to dry thoroughly.
4. Use a small drop of Dow Corning high vacuum grease (or equivalent).
5. Grasp the O-ring with the two greased fingers. Distribute the grease evenly and completely
around the O-ring.
Apply the grease sparingly. Too much grease may alter cell volume while too little
grease results in an imperfect seal and leaks.
6. Place the O-ring back into the groove on the cap and, with the greased index finger, gently
press it back into position.
7. Ensure the O-ring groove is properly greased. See
vious page.
