Install NCT to 7820A FID (For old version detector)
1. Cut FID makeup+hydrogen tubing between the "T" connector
and FID body.
2. Cap the open end of the makeup+hydrogen tubing from the
FID body using union 0100-0124 and stainless rod
07680-81150.
3. Cut the nickel catalyst mix weldment from the NCT assembly.
4. Use a union, 0100-0124, to connect the open end of the NCT
input tubing to the open end of the makeup+hydrogen gas
tubing coming from the T fitting.
5. The mixed makeup+ hydrogen gases now flow from the FID
"T" fitting into the nickel catalyst. Only air flows directly from
the UEPC into the FID.
