Replacing the Bellows on the 20 cm Survey Chamber
If the bellows on the 20 cm Survey Chamber is punctured or is otherwise damaged
and develops a leak, it will not operate properly. If the chamber fails to raise or
lower when the bellows pump is operating, the bellows and/or the Bev-a-line
tubing on the bellows air path may be damaged. Check the Bev-a-line tubing first
to see if it has developed a leak, and replace if necessary. If you have determined
that the bellows is damaged, you can replace it using the
LI-8100A Bellows Kit (p/n 8100-623).
Follow these steps to replace the 20 cm Survey Chamber bellows:
1. Remove the survey chamber hoses and chamber connector from the Analyzer
Control Unit side panel.
2. Remove the four nuts from the bottom of the chamber supports, as shown
below.
Remove the 4 nuts
from the support legs
3. Bend the supports out slightly to remove the bottom plate assembly.
4. Remove the four screws from the inside of the chamber as shown below, and
remove the chamber bowl from between the chamber supports. This will
expose the manifold and bellows assembly.
