The pump capacity should be approx. 112,5 ln/h, and thus 25% above
the typical sample gas flow rate of 90 ln/h.
Connect a hose to the Sample gas outlet port (10), if no electrochemi-
cal sensor is installed.
If the "active VENT" option is installed, an internal gas pump feeds the
sample gas completely to the Sample gas outlet port (10) and no sam-
ple gas enters the enclosure. A discharge gas hose can be connected
to the Sample gas outlet port (10).
►
Ensure that pollutant-free ambient air can be drawn in at the fresh air
inlet (11). If necessary, connect a hose here to bring in such fresh air.
►
In the case the option active vent is installed, note that the sample gas
at the exit may be diluted with ambient air and is therefore not ade-
quate to be reused in the process
The flow rate of the gas should be within 90 ln/h.
Otherwise, please check probe and filter for clogging.
Check also whether there is a device alarm.
Temperatures of NDIR and heating hose should be within the specified
range in order to guarantee a sufficient measuring accuracy.

See Chapter 13 Specifications, S. 102.
Attach clip-on filter
If you operate the analyser without a heated hose, dirt may collect in the
gas inlet.
►
In this case, plug the supplied clip-on filter onto the gas inlet (12).
