Analysis Subsystem

3Flex Service Manual

2-12

Aug 2013

The vacuum valve (7) should be kept closed when dosing gas in the manifold to maintain cleanliness
of the gauge. Open Valve 7 only when the system is under vacuum.

Right-click on the vacuum gauge reading to view vacuum gauge details (you must be in Service Test
mode). The combined reading is what you see displayed on the schematic.
