Clean the Nozzle
1.
Turn the fluid air OFF.
2.
Remove the flushing syringe.
3.
Use the 3 mm driver to remove the nozzle plate.
4.
Remove the diaphragm from the heater block.
5.
Inspect if the diaphragm or nozzle plate requires
further cleaning. Normally, the flushing process
achieves 90% clean.
6.
Hand-clean the diaphragm with a mild solvent
such as rubbing alcohol and a brush. A suitable
cleaning brush, pictured above, can be ordered from Advanjet (P/N CLB-01).
7.
The nozzle plate can be cleaned with a stronger solvent than the one used for
the diaphragm. If necessary, insert the nozzle plate in a small container of
acetone or isopropanol alcohol and immerse the container in an ultrasonic
cleaner for 5-10 minutes. If necessary, repeat a second time. Do not submerge
the nozzle plate for extended periods of time.
NOTICE
Diaphragms can be cleaned successfully with
a small amount of solvent and a soft brush and cotton swab.
Never submerge the diaphragm in solvents as it might result in damage.
Do not submerge the diaphragm into the ultrasonic cleaner because
it will deteriorate the diaphragm and shorten its life.
8.
When the ultrasonic cleaning is finished, remove the nozzle from its container
and wrap it in a paper towel, making sure the barb is still exposed. Use an air
hose to cover the barb and blow air through the plate for about three seconds as
shown in Figure 4-5.
9.
Using the tools in the Advanjet cleaning kit (P/N CL-XXX; XXX = nozzle size),
pass the cleaning drill through the nozzle plate barb to scrape out excess
material (see below center). Use the air hose again to blow out loosened material.
10.
To make sure the nozzle is absolutely clean, run a cleaning wire through the
nozzle (photo below). Make sure it is the correct size and that it is able to pass
through the hole. If not, either the wire is too big or the nozzle is still clogged.
Repeat ultrasonic cleaning, blowing out, and cleaning with the drill and wire.
