Purge Analyzer After Each Use
The analyzer should be purged after performing a combustion test. After removing probe
from the stack, let the pump run for at least 10-minutes to remove any stack gases and dry
any condensate from inside the sensor chamber and probe assembly.
Remove Moisture from Water Trap Before Storing
When storing the analyzer, it is recommended that users empty the water trap and leave it
open to prevent damage associated with prolonged exposure to moisture. See Emptying
the Water Trap (Section 5.1) for more information.
Maintain Sensor Calibration
Calibrate the analyzer every 6-months to 1-year to ensure its accuracy. See Calibration
(Sections 5.5 and 5.6) for more information.
