Refer to Section 2.2, Identification of Unit Controls and Components, prior to system
installation.
Helium Pressure Regulator Installation
Connecting the helium pressure regulator to a tank of pressurized helium.
Components needed:
• Pressure regulator for helium cylinder (with 0.45 micron in-line filter), provided with
unit (Figure 3.1).
• Cylinder of grade 4.5 to 5.0 helium (minimum 99.995% pure); maximum pressure of
2,600 psi, user supplied.
• 1 1/8" open-end wrench or a 10" or 12" adjustable wrench, user supplied.
Note: The regulator is intended for use only with helium gas under a maximum of 2,600 psi
of pressure. The outlet on pressurized helium cylinders used in the United States (maxi-
mum 2,600 psi) is compatible with the fitting supplied on the pressure regulator with the
PDS-1000/He unit (CGA 580, female fitting). Outside of the US, contact your local Bio-Rad
office for information regarding the proper cylinder/regulator fitting in your area.
