VI-Operation Instructions
1-Pour the cleaning solution into the cleaning tank (over 2/3 water level), and power on the ultrasonic
cleaner. Ensure that the device is securely grounded.
2-Press Time setting to set time, one minute each press (you can hold down this button to increase the
time continuously), 1-99mins cycle.
3-After time setting is complete, press Ultrasonic ON/OFF to turn on the ultrasonic. The time on the LED
window starts counting down. When the time runs up, it turns off, working light off.
4-Press Temperature setting to set the temperature, one degree each time(you can hold down this button
to increase the temperature continuously).The temperature is 0-80ºC cycle.
5 -After temperature setting is complete, press the Heating ON/OFF, the heating light is on, the LED
window shows the actual temperature, when the actual temperature reach to the setting temperature,
the heater stops work and the heating light is off, if the temperature of the cleaning solution in the tank
is higher than the preset temperature, the heater does not work.
VII - Factors Influencing Performance
1-Ultrasonic wave power density: Higher power density results in better cleaning performance and higher
cleaning speed. Higher power density is appropriate for cleaning ofwork piece with stubborn dirt, and
lower power density is suitable for any precision work piece (generally ultrasonic power density ranges
between 0,01 ~ 0,02w/ml).
2-Ultrasonic frequency: Lower frequency results in better cavitation performance. Higher frequency
contributes to better refraction/ reflection performance. Lower frequency should be applied for
cleaning of simple surface while higher frequency for cleaning of complex surface with deep or
inaccessible hole. (80 KHz, 130 KHz)
3 - Cleaning temperature: Ultrasound wave will present the best cavitation performance at a temperature
rangebetween 40 ~ 50 ºC. Higher cleaning temperature facilitates breakdown of dirt, while a
