Maintenance
It is recommended to periodically inspect the unit, both visually and physically, to insure
optimum and safe performance. This inspection should be scheduled as a routine
maintenance procedure, done with the unit power OFF and with the unit unplugged from
the AC power source.
Long exposure to acids or caustics results in corrosion of metal parts or components.
Check the generator, converter, and cables periodically for any signs of rust or
discoloration. If discoloration is found, move the ultrasonic processor away from the
source of the contaminant.
Examine the condition of the high voltage cable that attaches the converter to the
generator. Inspect the wire insulation for damage, such as wear, burning from hot plate
contact or breakage from extended use or rough handling. In general use, the cable
assembly should not be used to carry the converter or pull it toward the user. Make
certain the cable always has slack and is never tensioned. If necessary, move the
generator or converter assembly closer to one another to accomplish this. If this is not
possible, contact your Customer Service Representative to obtain a longer cable.
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
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 liquid solution.
Proper care of the probe is essential for dependable operation. During normal use 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 less often. The tip
must be examined for excessive wear and to ensure that the threaded connection is
clean and attached properly to the convertor. See probe tightening instructions if
necessary.
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.
