3. Carefully remove the retaining ring, PTFE o-ring, glass filter cover and filter
element.
4. Replace the filter, being careful that the element is fully seated and centered
in the bottom of the holder.
5. Re-install the PTFE o-ring (with the notches up), the glass cover, then screw
on the retaining ring and hand tighten. Inspect the seal between the edge of
filter and the o-ring to assure a proper seal.
6. Re-start the analyzer.
