 To connect the cryogenic system to the carbon dioxide supply
1. Connect the proper end of the cryo supply tube to the 1/8-in. NPT connection of the
solenoid valve using the proper nut and ferrule. Use a 7/16-in. wrench to tighten the
fittings. See Figure 21.

2. Connect the other end of the cryo supply tube to the coolant container using the
appropriate nuts and ferrules.
3. Connect the cryo valve to the Aux Temperature/Cryo Module.
IMPORTANT The Aux Temperature/Cryo module must be powered at the same line
voltage of the main GC system.
a. Connect the 2-pin connector marked Cryo Valves - Front Inlet or Cryo Valves-Back
Inlet to the cryo solenoid valve using the cable provided. See
Figure 22. Cryo Valves: Front/Back Inlet
b. Using the cable provided, connect the 15-pin female connector marked GC Bus on
the module to a Bus interface on the back of the GC.
