Identify Carrier Gas Controls and Turn on Flow
Gases are plumbed at the factory through the rear bulkhead fittings into the
inlet manifold, then to the pneumatic controls in the pneumatics compartment.
The pneumatic controls can be either electronically controlled (EFC) or
manually controlled and are different for each Injector system.

•
Carrier gas flow is adjusted at the user interface for EFC or at the
pneumatics panel for manual pneumatics. For manual pneumatics carrier
gas systems, identify the controls for carrier gas flow at the pneumatics
panel for your Injector system. These pneumatic controls are identified by
their location, i.e. front, middle, rear.
•
Turn on carrier gas flow by adjusting the manual flow controller or setting a
positive pressure or flow on the EFC system.
•
Verify that there is a positive pressure on the pneumatics panel pressure
gauge or FLOW/PRESSURE page Press .
