WARNING High pressures and extremely low temperatures make Liquid Nitrogen a
hazardous material. High concentrations of liquid nitrogen in the air can be an
asphyxiation hazard. To avoid injury, always follow the safety precautions and delivery
system design recommended by your gas supplier.
To connect the cryogenic system to the liquid nitrogen 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 Auxiliary Temperature/Cryo must be powered at the same line voltage
of the main GC system.
