5. Maintenance
ISM-3 requires for a minimum of maintenance and as the oxygen-sensor itself is very long
term stable, no calibration of the analyser in a normal application situation is needed
between the obligatory 12 months service control intervals.
See "Recommendations" on page 7 for details.
If ISM-3 is installed in places with more dust than normal, it may be necessary to change the
cooling air filter between the obligatory 12 months service control intervals.
When cleaning the front panel, use only water or a mild soap lather.
