The inlet should be cleaned based on the schedule in Table 4–1.

USTTRAK™ monitor off.
2. Unscrew the inlet nozzle from the instrument (Figure 4-2).
Figure 4-2: Unscrew Inlet Nozzle
3. Clean the inlet port. A cotton swab can be used to clean the outside of
the inlet port. The swabs can be dampened with water or a light solvent
(e.g., isopropanol). The inside of the sample tube can be cleaned 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.
Note
Be careful not to blow particles into the DUSTTRAK™ monitor
inlet port.

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