Flow Never Becomes Ready
If the gas flow never becomes ready, check for the following:
• Check the supply gas for sufficient delivery pressure.
• Check the restrictors installed in the Aux EPC module. See
Restrictors in the Advanced User Guide.
• Check the configured gas type. The configured gas type must
match the actual gas plumbed to the GC.
• Check for leaks in the gas delivery plumbing and the GC. (See
“Checking for Leaks”.)
