6.4.1 Particulate Filter Replacement
Contamination of the 5 micron filter can result in degraded performance of the instrument, including
slow response time, erroneous readings, temperature drift and various other problems. The frequency
which the filter needs to be replaced is heavily dependent on the environmental conditions the
instrument is sampling.
1. Turn OFF the external pump and allow the instrument to return to ambient.
2. Open the lid of the instrument to access the sample filter holder (located in front right hand
corner).
3. Remove the Kynar nut from the fitting.
