attached to the exhaust to capture NO

and low levels of ozone.
6.4.1 Particulate Filter Replacement
Contamination of the filter can result in degraded performance of the analyser, including slow
response time, erroneous readings, temperature drift, and various other problems.
1. Disconnect the external pump.
2. Slide open the lid of the analyser to access the particulate filter (located in front right hand
corner).
3. Unscrew the filter cap (bright blue) by turning it counter-clockwise.
4. Remove the filter plunger from the casing, place finger on tubing connector and pull to the side
(refer to Figure 52).
