7) If the filters appear soiled, it will be necessary to remount the external plate, and
remove the input lines. To remove the input lines, continue to the next step;
otherwise, move to step 8.
8) Using a ¼" open end wrench, loosen the Valco nut, and remove the input line.
Repeat for all sample, carrier and calibration gas lines.
9) Remove the 8–¼" hex socket mounting screws.
10) Remove the used filters from the filter sockets. Using an edged instrument or
fingernail, put pressure on the outermost edge of each filter to pop them out.
11) If replacing filters due to clogging, use compressed air to blow out the input holes
in the external plate. It may also be necessary to wipe clean the gasket located
on the internal plate; otherwise, move to the next step.
12) Using the replacement filter, carefully lay the filter into the filter socket, applying
uniform pressure to the filter. Do not use any pointed instrument to push the filter
into place. Repeat for each input stream, carrier and calibration gas input. Vents
do not require filters.
13) Reseat the external plate, aligning the mounting pins on the internal plate to the
corresponding holes on the external plate.
14) Replace the 8–¼" mounting screws, using a star pattern when tightening the
screws.
15) If the sample, carrier and calibration gas lines were removed, purge the air from
the transport tubing, and reconnect to the corresponding ports.
