13. Using the extraction tool, remove the cable connectors from J1, J2 and J3 jacks. Do not pull the
connectors from the board by the wires.
14. Using a 9/64” hex wrench, loosen the mounting screw inside the center of the assembly. When
loose, lift the assembly from the manifold assembly. Set aside on a clean, lint-free surface.
15. Verify that the manifold heater plate gasket is in place and in good condition.
16. Carefully insert the replacement module onto the manifold assembly, rotating the module to
ensure that the key holes line up and the module rests on the base. The device should not turn
once it is seated correctly.
17. When the GC module is in place, tighten the mounting screw.
18. Carefully restore the cable connectors to J1, J2 and J3 jacks, being careful to not press against
the wires attached to the connector head.
19. Replace the oven wall onto the GC module, being careful to not pinch or bind any of the cables.
When fully on, turn the oven wall clockwise to tighten.
20. Replace the thermal flask over the GC module. When the flask reaches the mounting bracket,
turn clockwise to tighten.
21. Follow the instructions in section
to Replace the digital controller complete assembly.
22. Plug the termination panel to the digital controller ribbon cable and then into the digital
controller assembly, if disconnected.
IMPORTANT NOTE:
Note that the termination panel to the digital controller ribbon cable pin 1
wire is not red. On the digital controller board, the red edge (pin 1) of the cable should plug onto
pin 50, the right side of the plug. The plug is “keyed”; do not force the plug into the connector.
23. Insert the lithium battery pack into the enclosure between the enclosure and the thermal flask.
24. Turn on all sample streams, calibration gas and carrier gas.
25. Once the device is reassembled, apply power to the analyzer.
26. Follow the Cold Start procedure in section
27. Reinstall the front and rear end caps.
IMPORTANT NOTE:
Note that since power was removed from this device, the analyzer will
perform startup diagnostics and stabilize. If the user has disabled the startup diagnostics, they
should be enabled and power cycled to the device. If power has been withheld from the device for
an unknown or lengthy period of time, a complete startup should be performed.

10.18 Replace the termination panel
This section presents the procedures for removal and installation of the power termination panel. This
panel is located in the rear of the analyzer. Read all procedural steps before removing the assembly.
