NOZZLE MAINTENANCE AND PERFORMANCE
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 edgewise 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 (REF: AC-103) 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 Replace the o-ring if it was removed earlier.
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 4.1).
13 Perform a Volume Test (Section 6.4).
NOTE:
You must perform the Hub Pattern Test and Volume Test before
operating the instrument. If the results are incorrect, manually prime the
instrument.
