What is the Ultrasonic Cleaning?
8
Ultrasonic cleaning is faster, more effective method for reducing the cleaning time
and cost than any other method - scrubbing soaking, steam and so on.
Ultrasonic sound is sound transmitted at frequencies beyond the range of human
hearing. As the sound waves from the transducer radiate through the liquid in the
bath, they alternate high and low pressures in the liquid.
During the low pressure stage, millions of bubbles form and grow. This process is
called Cavitation. During the high pressure stage, the bubbles collapse, or implode,
releasing enormous amounts of energy. They work in all directions, attack every
surface and invade all recesses and openings.

Cleaning Method
Operating Method
1. Fill the bath with warm water. The liquid should come to within 3 Cm from the top of the bath
when the tray and items to be cleaned are submerged.
2. Add the cleaning solution to the water, if necessary.
3. Plug the cleaner into its power source and press POWER button to ON.
4. Slowly lower the tray into the bath.
5. Select the SONIC by MODE button and control the strength of sonic.
6. Select TIME by MODE button and set the operating time by UP/DOWN button.
7. Select the TEMP by MODE button and set the temperature by UP/DOWN button.
8. After inputting all parameters, push the START/STOP button to start cleaning.

There are two methods of cleaning - direct and indirect.
Each has advantages and disadvantages. when in doubt, run test samples using both methods to
decide which one produces best results.
(1) Direct method
The advantages of this method are simplicity of operation and cleaning effectiveness.
ㆍAll removed soil remains in the bath.
ㆍOnly one solution can be used at a time.
ㆍHighly acidic or caustic solutions can erode the bath surface.
▶Fill the bath with warm water and cleaning solution.
▶Place the items to be cleaned in a tray and lower them into the bath.
You can also suspend items on a wire and then immerse them in the solution.
(2) Indirect method
The advantages of this method are
ㆍRemoved soil stays in the beaker or tray so you can easily examine, filter or discard it.
ㆍYou can use also one or more solutions at the same time.
ㆍCleaning solution in your bath needs to be changed less often.
▶Fill the bath with warm water and a cleaning solution.
▶Pour your solution medium into one or more beakers or into a solid tary.
▶Place the beakers in a beaker positioning cover or a solid tray to fit your cleaner.
Beakers should not touch the baths bottom.
