viewing it from the outside. However, the majority of collected particulate will be on the inside of the element
and therefore requires disassembly for proper inspection.

Filter Disassembly/Reassembly
–
Replace/inspect the sample filter element as follows:
1.
Loosen bolt on bottom of filter until it is free of the top cap.
2.
Gently pull apart assembly and remove old element.
3.
Wipe surfaces clean.
4.
Prior to re-assembly, inspect o-rings on top and bottom caps and on center bolt for
any possible damage. Replace if necessary
5.
Place the new element into the groove in the bottom cap.
6.
Install glass shell onto bottom cap with a slight twisting motion to help the o-ring
seat properly.
7.
Be sure that element is seated correctly and parallel to glass shell.
8.
Carefully assemble the bottom assembly onto top cap while being sure the element
is properly aligned with the protrusion on the top cap that keeps the element
centered. A slight twisting motion will help the o-ring seat properly.
9.
Inspect the assembly for properly sealed o-rings. They will appear as lines that are
about 1mm wide inside the glass shell. Check for gaps, twists or inconsistencies of
the seal line.
10.
Replace bolt through hole in bottom piece and screw clockwise into top piece. Do
not over-tighten center bolt. It should be just tight enough so it does not vibrate
loose. Over-tightening will not help the filter to seal.

If there is visible condensate collecting at the bottom of the filter, the drain system is not operating properly.
•
Model PCD-3000-W. Remove the drain metering tube at the eductor and check for vacuum at the
eductor inlet.
o
If there is vacuum, it is likely that the metering tube is clogged. Clean with a fine wire or
replace.
o
If there is no vacuum, confirm that system instrument air pressure is present. Check for airflow
out of the eductor exhaust (drain port).
▪
If no flow, shut down the system, turn off the system instrument air supply and remove
the tubing from the nozzle of the eductor.
