6.2 Nozzle Reassembly
1. Hold your thumb or a nozzle strainer over the end of the tube to keep
the nozzle parts in the tube. Discard the cleaning solution according to
applicable statutes.
2. Inspect the nozzle parts. Remove any material in the swirl cone grooves by
sliding a piece of paper along each of the 4 grooves.
3.
Thread the nozzle orifice cleaning wire (REF: AC-059) through the back of
the disassembled nozzle housing.
4. Place the nozzle parts back into the tube and rinse them with water.
5. Rinse the parts again with alcohol.
6. Apply a small amount of silicone lubricant to the compression screw
threads.
7. Reassemble the nozzle by placing the compression screw on the nozzle
disassembly tool, then inserting the swirl cone into the compression screw.
NOTE:
Hold all the parts in a vertical position during reassembly.
8. Reinstall the nozzle housing over the swirl cone and compression screw.
9. Reinstall the nozzle insert.
10. Return the assembled nozzle to its original position in the instrument.
11. Repeat Steps 1 through 10 for each nozzle.
12. Perform a Hub Pattern Test (Section 4).
13. Perform a Volume Test (Section 6.4).
NOTE:
The Hub Pattern Test and Volume Test must be performed before
operating the instrument. If the results are incorrect, manually prime the
instrument.
