Rev. 6-12157. Operating Instructions (Getting Started)CAUTION Do not operate the pow er 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 w asher betw een the converter, probe or horn. Never apply grease to the mat ing surfaces or threads of the converter, probe orMicrotip. Should it become necessary to remove a probe, use the w renches supplied. Neverattempt to remove the probe by tw isting the converter housing or holding it in avice, as this may damage the electrical connections w ithin the housing.CAUTIONLOW SURFACE TENSION LIQUIDS – ORGANIC SOLVENTSThe probes (solid or w ith a replaceable tip) are tuned elements that resonate at a specific frequency.If the replaceable tip is removed or isolated from the rest of the probe, the element w ill no longerresonate at that frequency, and the pow er supply w ill fail. Unlike aqueous (w ater based) solutionsw hich rarely cause problems, solvents and low surface tension liquids are problematic. These liquidspenetrate theprobe/replaceable tip interface, and force the particulates into the threaded section isolating the tipfrom the probe. When processing low surface tension liquids, ALWAYS use a solid probe.Set-up:1. Connect the pow er cord into the receptacle on the rear of the ultrasonic processor.2. Make sure the unit is sw itched off. Plug the electrical line cord into the electricaloutlet.3. If the optional foot sw itch is used, insert the plug into the jack located on the rearpanel.4. For best results it is critical to use the appropriate size and type of accessory toprocess your sample. If you are not sure that you have the proper horn for your samplevolume please refer to the Accessories section of this manual or call the manufacturerfor assistance.5. Horns/Probes must be properly tightened. Depending on the accessories purchased,often the horn and the flat tip are attached to the converter at the factory. Check thetightness of the horn and flat tip by using the wrench set. Please refer to images in theMaintenance section of this manual. A loose horn or tip may cause damage to thegenerator circuitry or parts of the converter and horn. A loose horn may also show a
