Run PC Service App Vaporizer Test (Section 12.10.2) to verify hardware performance.
Replace and retest in the following order (Also see Section 7.10.):
• Proportional Valve
• ADB
This error can also be caused by the following:
• Liquid Flow Prevention Valve actuated. Look for occurrences of CONDENSATION CONDITIONS EXIST
and CASSETTE OVERFILL DETECTED errors preceding this error.
• Cassette held in place, but not latched, during agent delivery. It is possible to hold the cassette in a
position such that the cassette ID is recognized but the cassette valves are not open, preventing flow.
• Check cassette travel to ensure deformation or under sizing of cassette bay is not causing undue
restriction.
