WARNING: Do not use a cable with broken end connections, exposed wires or
frayed insulation. High voltage is present in the cable and will pose a shock
hazard. Do not touch the converter assembly until the power switch is off and the
unit is unplugged.
Probe Maintenance
Ultrasonic processors vibrate probes at a high intensity. While operational, the converter-
probe assembly should be supported properly and the probe tip should be suspended to
vibrate freely in a liquid. The sides and end of the probe must
never
be allowed to come
in contact with anything but the solution.
Proper care of the probe is essential for dependable operation. The intense cavitation
will over time will cause the tip of the probe to erode. For that reason,
it is
recommended that a Preventative Maintenance (PM) schedule be adopted to
examine the unit at regular intervals.
The PM schedule should depend on frequency of use. Weekly maintenance schedules
are recommended for units used frequently or monthly for those used infrequently. The
tip must be examined for excessive wear and to ensure that the threaded connection is
clean and attached properly to the convertor. Use a cotton swab and alcohol (i.e.
ethanol, isopropyl, etc.) to clean the threaded mating surfaces.
When excessive wear (corrosion/pitting of the probe tip) is detected the probe
should be replaced before performance is diminished.
Note:
A loose converter-booster-probe assembly will usually generate a loud piercing or
squealing sound.
WARNING: Hand-tightening horns onto the convertor is not sufficient; properly
tighten them with the appropriate Wrench Set.
See the
steps on pages 10-18 for
attaching and detaching probe assemblies.
System Cleaning Instructions
The generator and converter may be cleaned using an acid-free cleaning solution (i.e.
glass cleaner) and a soft cloth.
Probes should be cleaned using isopropyl alcohol. Probes are made from titanium and
can be autoclaved (the converter is an electrical part and cannot be sterilized in this
manner). Before each procedure place the probe tip in water or alcohol and turn the
power on for a few seconds to remove residue. The tip also can be sterilized using
alcohol with the power on.
