Identification Labels
Labels on the gas lines identify their function in the system as follows:
SUPPLY (color coded red) Helium gas supply to the cold head from the

Separate labels are furnished by SCAI with standard gas lines for the customer to attach to the
gas lines. See the Installation section in the System manual.
