The exhaust from the analyzer must be vented outside the shelter or immediate area
surrounding the instrument and conform to all safety requirements using a maximum
of 10 meters of 1/4" PTFE tubing.

Pneumatic Connections–Basic Configuration–Using Bottled Span Gas
1. Attach a 1/4" exhaust line between the external pump and the EXHAUST port of the
analyzer.
2. Attach an additional 1/4" exhaust port of the pump.
3. Attach a sample inlet line to the SAMPLE inlet port. Ideally, the pressure of the
sample gas should be equal to ambient atmospheric pressure.
Maximum pressure of any gas at the SAMPLE inlet should not exceed 1.5 in-Hg
above ambient pressure and ideally should equal ambient atmospheric pressure.
In applications where the sample gas is received from a pressurized manifold, a
vent must be provided to equalize the sample gas with ambient atmospheric
pressure before it enters the analyzer.
The vented gas must be routed outside the immediate area or shelter
surrounding the instrument.
4. Once the appropriate pneumatic connections have been made, check all pneumatic
fittings for leaks using procedures defined in Section 7.5.1.
