Maximum Pressure:
Ideally the maximum pressure of any gas at the sample inlet should
equal ambient atmospheric pressure and should NEVER exceed
1.5 in-hg above ambient pressure.
Venting Pressurized Gas:
In applications where any gas (span gas, zero air supply, sample gas
is) received from a pressurized manifold, a vent must be provided to
equalize the gas with ambient atmospheric pressure before it enters
the analyzer to ensure that the gases input do not exceed the
maximum inlet pressure of the analyzer, as well as to prevent back
diffusion and pressure effects. These vents should be:
• at least 0.2m long
• no more than 2m long
• vented outside the shelter or immediate area surrounding the
instrument.
Dust Plugs:
Remove dust plugs from rear panel exhaust and supply line fittings
before powering on/operating instrument. These plugs should be kept
for reuse in the event of future storage or shipping to prevent debris
from entering the pneumatics.

MPORTANT Leak Check
Run a leak check once the appropriate pneumatic connections have
been made; check all pneumatic fittings for leaks using the
procedures defined in Section 11.3.2.
See Figure 3-4 and Table 3-3 for the location and descriptions of the various pneumatic
inlets/outlets referenced in this section.
Note: Depending on the application, some instruments may include an internal pump. Refer
to any addendum that may accompany this manual for information pertaining to
custom configurations.
