Replace the Analysis Port Filter
To avoid analysis problems, the new filter and O-ring must be clean. Wear gloves when performing this task. Do not touch the parts with bare hands. |
- Remove the dewar and sample tube (or plug).
- Close the sample valve.
- If the O-ring and filter are stuck in the port, use a fingernail or plastic instrument to remove them. Using a metal instrument may scratch the sealing surface, causing a leak.
- Replace the filter and the O-ring.
- Carefully reassemble the sample tube fitting, filter, O-ring, and manifold connector; then hand tighten. Then tighten with a wrench to prevent leaks when evacuated.
