Replacing the scrubber and scrubber efficiency indicator
1. Close the sample supply shut-off valve. Allow all residual gas to dissi -

2. Unscrew the compression nuts on the inlet end of the scrubber and
scrubber efficiency indicator assembly.
3. 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, as
shown below.
4. Tighten all new fittings 1-1/4 turns with a wrench from finger tight.
For connections with previously swaged ferrules, thread the nut to the
previously pulled up position, then tighten slightly with a wrench.
5. Reset the scrubber lifetime monitor with the New Scrub Installed
parameter and the General Fault Alarm with the Reset option for the
General Alarm DO parameter (see “To change parameters in Mode
2” in the Description of Device Parameters for your analyzer).
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
