8.2 Replacing the Sample Particulate Filter

The particulate filter should be inspected often for signs of plugging or contamination. It is also

common for dirt particles to absorb NO

, thus causing those readings to be low.

To check and change the filter:

Fold down the M200A front panel.

Locate the filter on the left side of the analyzer front panel. See Table 8-8-3 for an

exploded view of the filter assembly.

Visually inspect the filter through the glass window.

If the filter appears dirty, unscrew the hold-down ring, remove the teflon o-ring and then

the filter.

Replace the filter, being careful that the element is fully seated in the bottom of the

holder. Replace the teflon o-ring, then screw on the hold-down ring and hand tighten.
