11.3. MAINTENANCE PROCEDURES
The following procedures need to be performed regularly as part of the standard
maintenance of the T100.
11.3.1. 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 11-1 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.
IMPORTANT
IMPACT ON READINGS OR DATA
Do not touch any part of the housing, filter element, PTFE retaining ring,
glass cover and the O-ring with bare hands, as contamination can
negatively impact accuracy of readings..
To change the filter according to the service interval in Table 11-1:
1. Turn OFF the analyzer to prevent drawing debris into the sample line.
2. Open the analyzer’s hinged front panel and unscrew the knurled retaining ring of the
filter assembly.
