7. OPERATING INSTRUCTIONS
7.1. CAUTION
•
Do not operate continuously for more than 1 minute.
•
Do not operate the power supply unless it is connected to the converter.
•
Never allow liquid to spill into the converter.
•
Do not allow a probe to vibrate in air for more than 10 seconds.
•
Do not allow the vibrating probe to contact anything but the sample.
•
Never place a washer between the probe and the converter.
•
Never apply grease to the mating surfaces or threads of the converter or probe.
•
Should it become necessary to remove a probe, use the wrenches supplied. Never
attempt to remove the probe by twisting the converter housing, as this may dam-
age the electrical connections within the housing.
Note: The temperature of the converter front area (where the probe attaches) should never
exceed 60 º C (140 ºF). If this temperature is reached, shut the system off and allow to cool.
Do not allow the system to operate for more than 1 minute without a rest or pulse to prevent
overheating.
7.2. SETUP
1.
Ensure that the amplitude control knob is set to 0.
2.
Plug the electrical line cord into the electrical outlet.
3.
If the optional foot switch is used, insert the plug into the jack located on the rear
panel. Do not insert footswitch plug while the system is powered on.
4.
Probes must be properly tightened. If the convertor and probe assembly is not
already assembled; screw the probe onto the converter and using the wrenches
provided tighten it securely. Check the tightness of an already assembled probe
by using the wrench set. Please refer to images in the Maintenance section of this
manual for tightening instructions. A loose probe may cause damage to the gen-
erator circuitry or parts of the converter and probe. Always use the wrenches sup-
plied with the unit.
5.
Small Sonicators such as the Q55 should be operated in on and off pulses to pre-
vent the converter from overheating. Overheating the converter can cause perma-
nent damage, may crack the probe tip and will void the warranty.
6.
To prevent sample overheating, sonication can be manually pulsed on and off by
using the converter thumb switch, foot switch or by manually turning the ampli-
tude knob setting up/down as needed.
Important: Do not flip the main power switch on/off to pulse sonication.
7.
Probe tips wear after normal use. Using a severely worn probe tip can damage
internal generator components.
