Sample Filter Replacement
Inspection Frequency: Inspect the sample filter before and after each use of the
instrument.
What to Look For: When inspecting the sample filter, look around the entire outside
diameter of the white filter element located inside of the plastic housing. Look for red
spots or the beginnings of discoloration on the white outside diameter of the element.
Do not look into the round ends of the white element for red spots or discoloration—
the round ends of the filter may always appear red. If red spots or discoloration are
discovered, the sample filter requires replacement to prevent the influx of particulate and
oil mists into the instrument.
Sample Filter Replacement Procedure:
1. Obtain replacement filter No. 16912.
2. Remove the existing filter from the retaining clip of the instrument by pulling
straight up and out.
3. Carefully remove the flexible, black, rubber tubing connections from both ends of
the existing filter. Do NOT allow the tubes to slip back into the internal portion of
the case.
4. Discard the existing filter according to local, state, and federal requirements.
5. Install the tube ends onto the barbs of the replacement filter, aligning the flow arrow
of the filter with the flow arrow on the instrument.
6. CAREFULLY slide the tubing back into the internal portion of the instrument, and
seat the new filter into the retaining clip.
7. Inspect the sample hoses for signs of oil entrapment. Replacement of the sample
filter usually requires cleaning or replacement of the sample hoses.
