In this application is often preferred that the sample gas and the source gas for the O
3
generator and internal zero air be the same chemical composition.

SAMPLE GAS & DRY AIR SOURCES
For instruments located in the same room, being monitored there is no need to attach the
gas inlet lines to the SAMPLE inlet or the dry air inlet.
EXHAUST OUTLET
Attach an outlet line to the EXHAUST outlet fitting.
In order to prevent the instrument from re-breathing its own exhaust gas (resulting in
artificially low readings) the end of the exhaust outlet line should be located at least
2 feet from the back panel of the instrument.
Once the appropriate pneumatic connections have been made, check all pneumatic
fittings for leaks using the procedures defined in Section 11.3.4.
