6.2 Replacing the Sample Particulate Filters

The particulate filter should be inspected often for signs of plugging or contamination. It is also common for dirt particles to cause instrument drift, and affect accuracy.

To check and change the filter:

1.Fold down the Bypass Pump Module front panel.

2.Locate both filters on the left and right side of the Pump Module front panel. See Figure 2 for an exploded view of the filter assembly.

3.Visually inspect the filter through the glass window.

4.If the filter appears dirty, unscrew the hold-down ring, remove the Teflon o-ring and then the filter.

5.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.

NOTE:

Handle the wetted surfaces as little as possible and clean with cloth prior to assembly
