Constant Pressure Cylinder
18.
Ensure that the pre-charge and product inlet valves on the constant pressure cylinder are closed.
19.
Tube from the pre-charge pressure supply to the pre-charge inlet valve on the constant pressure cylinder.
If the GSS-4PM is equipped with the standard probe and process gas will be used to pre-charge the constant pressure cylinder,
remove the plug from the probe base, and then tube from this port to the pre-charge valve on the constant pressure cylinder.
Welker recommends first installing a valve to the port on the probe base.
If the GSS-4PM is equipped with the optional LE-2SSKO and process gas will be used to pre-charge the constant pressure
cylinder, remove the plug from the back of the regulator, and then tube from this port to the pre-charge valve on the constant
pressure cylinder.
If the optional auxiliary instrument air supply will be used to pre-charge the constant pressure cylinder, remove the plug from
the back of the regulator, and then tube from this port to the pre-charge valve on the constant pressure cylinder.
20.
Tube from the sample outlet on the base of the GSS-4 to the product inlet valve on the constant pressure cylinder.
21.
Pre-charge the constant pressure cylinder. Refer to the
