6. Maintenance
6.1 General Maintenance
A regular schedule of maintenance will help ensure continued operation of the MultiGard 5000 Gas
Sampling System. Calibration of sensor(s)/analyzer(s) should occur promptly after the indication of a
“sensor out of tolerance” event and otherwise periodically to ensure proper operation.
WARNING
The only absolute method to ensure proper operation of a
sensor/analyzer is to check it with a known concentration of gas
for which it has been calibrated. Consequently, calibration checks
must be included as part of the routine inspection of the system.
At regular intervals, depending on cleanliness of the area being monitored, all particulate filters
should be checked and changed if necessary. All sample lines should be checked for leaks to avoid
sample dilution and lower than actual erroneous readings. Exhaust lines should be checked for
obstruction.
Upon indication of any trouble by the MultiGard 5000 Gas Sampling System, the cause should be
determined and corrected promptly. The trouble shooting section may help in determining possible
causes of the trouble indication.
