7. Operating Instructions
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 microtip to vibrate in air.
Do not allow the vibrating microtip 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 microtip.
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 damage the electrical connections
within the housing.
Note:
Overheating will damage the converter.
Standard probes/horns can operate at a maximum
temperature of
140
0
F
.
Set-up:
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.
4.
Probes must be properly tightened.
If the convertor and probe assembly is not already
assembled; screw the probe onto the convertor 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 generator circuitry or parts of the converter and probe. A
loose probe may also show a fluctuation in wattage readings.
Always use the wrenches
supplied with the unit.
5. Small sonicators such as the Q55 should be operated in a pulse mode to prevent the converter
from overheating. Overheating the converter can cause permanent damage and void the warranty.
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 amplitude knob setting
up/down as needed.
Important:
Do not flip the main power switch on/off to pulse sonication.
6. Overheating the sample and converter/probe assembly could potentially crack the tip.
7. If using a laboratory stand, mount the convertor /probe assembly using a clamp. Be sure to secure
the clamp to the upper section of the convertor housing only. Do not secure the clamp to any other
portion of the convertor/probe assembly.
8. Connect the convertor cable to the power supply.
