5.1 Routine Maintenance

Aside from normal cleaning and checking for leaks at the gas
connections, routine maintenance consists of recalibration and periodic
inspection of essential analyzer parts. For calibration procedures, refer to
Section 4.5.2. The periodic inspection of analyzer parts helps ensure
continuing high performance and reduces malfunctions that could lead
to analyzer downtime.

5.2 Routine Maintenance Schedule

Perform a routine calibration of the analyzer at least once every one to
two weeks. Keep a log of the percentage zero and percentage span
deviation settings. This ensures not only that accuracy is maintained; it
also may help in troubleshooting the analyzer if these settings vary
widely at each calibration or vary consistently up or down scale. If the
readings are stable from calibration to calibration, then the frequency of
routine calibrations can be decreased accordingly.
Check the sample flow rate at least every one to two weeks. Use the
Flow function from the System menu to check and adjust the sample
flow rate to approximately 100 ccm.
Check for excessive accumulation of dirt. In dusty locations, you may
need to wipe or gently blow off dust from the various sections at least
once a week. Any accumulation of dust or oil film hinders satisfactory
operation.
On an annual basis, check the gas lines for signs of leaks.
