4. Use a standard flathead or a Phillips screwdriver and loosen the four detector block

thermistor wiring screws (Item B).

Figure 2-7: Detector Block Wiring

A. Detector block screw

B. Thermistor wiring screws

C. Thermistor wires

D. Thermistor nuts

5. Use a standard flathead screwdriver and remove the two detector block screws

(

Figure 2-7

, Item A) and remove the detector block.

6. Remove the two 

-in. thermistor nuts (

Figure 2-7

, Item D).

7. Remove the thermistors and the PTFE seals from the detector block.
8. Replace the thermistor seals and the thermistors (Kit P/N 2-3-0500-521) that

shipped with the retrofit kit.

9. Thread the thermistors through the two 

-in. thermistor nuts and tighten the nuts.

Using the proper wrench, apply 20 ft.-lb. of torque.

10. Reattach the detector block using the two flathead screws.
11. Attach the terminal wires for the thermistors and tighten the four screws (see

Figure 2-7

).

12. Install the upper enclosure cover (

Figure 2-6

). Make sure that the cover is correctly

seated and tightly closed.

13. Install the insulation cover.
14. Turn on the gas chromatograph power.

Adjusting the carrier pressure

This section describes the carrier pressure adjustment after performing the helium to
hydrogen gas conversion.

Procedure

1. Adjust the carrier pressure to approximately half of what it was with the helium.
