CAUTION: THIS INSTRUMENT IS NOT DESIGNED TO HANDLE
HAZARDOUS GASES.
OZONE EMISSIONS CAN OCCUR IF AIR OR
MOISTURE ARE IONIZED IN THE SAMPLING
SYSTEM. THE SAMPLE PATH MUST BE
RELATIVELY FREE OF AIR AND/OR MOISTURE
BEFORE APPLYING THE IONIZING VOLTAGE.
KEEP THE SERIES 1200 POWER OFF UNTIL THE
ANALYZER IS FULLY PURGED.
Note: Air leaking into the sampling system will cause erratic or
unsatisfactory analyzer operation. Even if air is admitted
into the system for only a few minutes, you must purge the
regulator and the system for at least 1 hour before the
readings stabilize. See Section 3.6.
