2.9 Vacuum Pumps

Two field-replaceable pumps provide a redundant vacuum source for the transport and sample
flow system. One pump in the system draws vacuum while the other is idle. The pump exhaust
connects to the manufacturing facility central toxic exhaust system.
Note: The exhaust line from the Vertex M should not exceed 50 feet.
The pumps are located in the bottom of the Vertex M system cabinet inside a sound-deadening
enclosure to reduce noise. Three cooling fans circulate air over the pumps.
The Vertex M system draws cooling air in through a filter mounted on the pump module access
door.

2.10 Multiple Gas Monitoring

A Vertex M system equipped with two or more types of Analyzer modules can monitor more
than one gas (or groups of gases such as hydrides or mineral acids) at a location. Each Vertex
M Analyzer module can monitor only one gas family (such as hydrides or mineral acids).
