Re-assemble the cartridge. Align the two halves of the alcohol cartridge
and press firmly until they snap together. The cleaning/replacement
procedure is complete.
Cleaning Inlet Screen Assembly
The inlet screen assembly protects the instrument from contamination by
coarse particles and/or fibers. When the inlet screen is clean, it has almost no
affect upon the instrument particle counting. However, if the screen becomes
plugged with lint or fibers, it may cause a reduction in particle
counting efficiency.
The screen should be cleaned on a regular basis to prevent the build-up of
fibers or contamination. The intervals between cleaning will be determined
by the amount of use and the conditions of use. As a general rule-of-thumb,
whenever there is any noticeable contamination on the screen, it should
be cleaned.
To clean the inlet screen assembly, do the following:
1. Disconnect the inlet screen assembly from the instrument by depressing
the quick-connect fitting button and pulling the assembly away from
the instrument.
2. Unscrew the two halves of the assembly and remove the inlet screen.
3. Clean off any accumulations with compressed air.
4. Reassemble the inlet screen assembly, taking note of the screen
orientation. See Figure 4.4. Screw the two halves securely together
(finger-tight only). Failure to properly tighten the inlet fitting halves
may result in a particle leak and the inability to “zero check”
the instrument.

5. Install the inlet screen assembly into the quick-connect fitting and attach
the sample tubing.
