SYSTEM CLEANING INSTRUCTIONS
The power supply and converter may be cleaned using an acid-free cleaning solution (i.e. glass
cleaner).
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.

TROUBLESHOOTING
The most probable causes for malfunction are listed below and should be investigated.
A connector or cable is damaged.
The unit was plugged into an electrical outlet that provides a different voltage from that
required. See
Electrical Requirements.
The probe is not tightened properly with the wrenches provided.
The converter and/or probe has been dropped.
A probe being operated is damaged or worn past its useful life.
A fuse(s) has failed. If a fuse(s) has failed, proceed as follows:
1. Turn the unit off by depressing the
O
key, and disconnect the line cord from the
electrical outlet.
2. Open the fuse holder cover using a small screwdriver and pull out the red fuse holder
from its housing.
3. Replace the fuse(s).
4. Reconnect the line cord to the electrical outlet, press the
I
key and set the amplitude
to 100. With the probe in air (out of the sample), the wattmeter should read below 10
watts. If the reading exceeds 10 watts, press the
O
key, and disconnect the probe
from the converter.
5. Press the
I
key. If the wattmeter reads below 10 watts, the probe has failed or is out
of tune due to excessive erosion and should be replaced. If the wattmeter reads
above 20 watts, either the converter or power supply has failed and the complete
Ultrasonic Processor should be returned for repair.
OVERLOAD CONDITION
If the Ultrasonic Processor stops working and an OVERLOAD indication is displayed on the
screen, check for possible causes as outlined in the above paragraph, then press the
O
key to
switch the unit off, and the
I
key to switch the unit back on.
If the problem persists after inspecting all of these, please contact Customer Service at
or 203-270-4600 for additional assistance or to replace a worn
microtip or damaged part.
