If scrubber replacement is necessary, follow the procedure below. Replacement
scrubbers, scrubber efficiency indicators, and other replacement parts can be
ordered by the part numbers listed in Appendix A.
To replace the scrubber and scrubber efficiency indicator
1. Close the sample supply shut-off valve.
2. Allow all residual gas to dissipate as indicated by no flow on the
sample bypass flow meter.
3. Unscrew the compression nuts on the inlet end of the scrubber and
scrubber efficiency indicator assembly.
4. To install the new scrubber and indicator, insert the inlet and outlet
tubes into the compression fittings of a new scrubber and scrubber
efficiency indicator assembly, ensuring each are oriented correctly,
according to the flow pattern shown in Figure B–19 on page B–24.
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
