pressurize sample inlet.
CAUTION:
If the analyzer contains an optional internal sample pump, the introduction
of a sample gas with pressure in excess of 2.0 PSIG will damage the pump.
The optional pump is capable of drawing a sample through a ¼-inch heated sample line of
approximately 85 feet.
Sample Gas Bypass Outlet and Vent
A sample gas bypass outlet connector is located on the analyzer’s rear panel (¼-inch
