Adding Helium Gas
Use only 99.999% pure helium gas.
If the compressor helium pressure gauge reads 0, decontamination is required. Refer
to the Helium Circuit Decontamination on page 5-9, or contact the Product Service
Department.
1. A user-supplied helium charging line terminating in a 1/4-inch female flare fit-
ting, and a two-stage pressure regulator rated at 0-3000/0-400 psig is required
for this operation.
2. If you need to add helium more than once every several months, check for
leaks caused by improperly connected self-sealing connections or any mechan-
ical joint within the compressor.
Equipment Damage
To avoid damaging the cold head and other parts through contamination,
maintain pressure in the cold head.
