9.3. Maintenance Procedures
The following procedures need to be performed regularly as part of the standard maintenance of
the Model 6200E.
9.3.1. Changing the Sample Particulate Filter
The particulate filter should be inspected often for signs of plugging or excess dirt. It should be
replaced according to the service interval in Table 9-1 even without obvious signs of dirt. Filters
with 1 and 5 µm pore size can clog up while retaining a clean look. We recommend handling the
filter and the wetted surfaces of the filter housing with gloves and tweezers. Do not touch any
part of the housing, filter element, PTFE retaining ring, glass cover and the O-ring with bare
hands.
To change the filter according to the service interval in Table 9-1:
1. Turn OFF the analyzer to prevent drawing debris into the sample line.
2. Open the M6200E’s hinged front panel and unscrew the knurled retaining ring of the filter
assembly.

3. Carefully remove the retaining ring, glass window, PTFE O-ring and filter element.
4. Replace the filter element, carefully centering it in the bottom of the holder.
