Figure 9-1: Sample Particulate Filter Assembly
Carefully remove the retaining ring, glass window, PTFE O-ring and filter element.
Replace the filter element, carefully centering it in the bottom of the holder.
Re-install the PTFE O-ring with the notches facing up, the glass cover, then screw on the
hold-down ring and hand-tighten the assembly. Inspect the (visible) seal between the
edge of the glass window and the O-ring to assure proper gas tightness.
Re-start the analyzer.
