Maintenance
3. Clean the inlet port. Use a cotton swab to clean the outside of the inlet
port. You may dampen the swabs with water or a light solvent (e.g.,
isopropanol). Clean the inside of the sample tube by using a small brush,
along with a light solvent. Dry the tube by blowing it out with compressed
air, or let it air-dry thoroughly.
Be careful not to blow particles into the DustTrak monitor
inlet port.

4. Screw (hand-tighten) inlet back into instrument.

Impactor and the impactor plate
using a clean brush and a light
solvent. Dry impactor parts by

the impactor plate. DO NOT over-
