Sample inlet: | Attach clean, dry sample gas to the inlet port. |
| Note that the calibration gases ( zero and span) |
| also connect to this port. |
| Input gas flow t should be constant within the |
| range of 0.5 L/min ±0.2 L/min. |
Sample outlet: | Attach tubing for exhausting sample or calibration |
| gases. The exhaust line should be directed to an |
| appropriate safe vent depending on the nature of |
| the sample/calibration gas used. |
Purge gas inlet: | Used to connect a purge gas for purging the |
| internal housing of the analyzer. Use dry N2 or |
| instrument air for purge gas. (Flow rate is 1L/min |
| or more. Keep dust or moisture/mist from |
| entering the purge line. |
CAUTION: THIS INSTRUMENT IS DESIGNED TO HANDLE HAZARDOUS GASES. WHENEVER A FITTING IS OPENED, USE A NEW FERRULE AND CONE TO SECURE A GAS TIGHT SEAL. EACH FITTING MUST BE LEAK CHECKED WHENEVER A CONNECTION HAS BEEN OPENED OR DISTURBED IN ANY MANNER.
