ULTRASONIC CLEANER KBUS2640
USER MANUAL

ULTRASONIC PRINCIPLE
PREPARATION:
1. Carefully unpack the cleaner, remove all packing materials and check whether any parts
have become loose or damaged during transit.
Contents: a: Main machine b: Sound proof lid c: Power cable
d: Outlet filter e: Mesh basket (Optional) f: Manual
2. Place the cleaner on a flat, clean surface and ensure that the cooling fan will get adequate
ventilation, and that all controls are set to off, and the drain tap is closed.
3. Ensure that the power cables are securely and correctly connected with the single phase
switch(220V) or three-phases switch(380V), and that no part of these cable is likely to
contact with moisture or water.
4. Carefully fill at least 1/2 of the tank with a solvent solution. Based on cleaning requirements,
we recommend to use a small amount of cleaning solution because this will help increase
the cleaning performance. Now the cleaner is ready for use.
Ultrasonic cleaning is based on the cavitation effect caused
by high frequency ultrasonic wave vibration signal in the
fluid. Microscopic bubbles are formed, and then implode
violently causing the cavitation which create an intense
scrubbing action on the surface of the item being cleaned.
The bubbles are small enough to penetrate microscopic
crevices, cleaning them thoroughly and consistently.
Ultrasonic cleaning is extremely effective at removing dirt
and grime which would normally require tedious manual
cleaning by hand. It has been used to clean a wide variety of
instruments and mechanical parts such as carburetors,
returning them to almost “like new” condition without
damage to delicate parts.

OPERATION Instructions
1. Fill the stainless steel tank with cleaning solution; turn the single phase switch or three
phases switch on; After power-on, the LED display of the temperature displays the actual
environmental temperature; while the LED display of time displays 3 minutes (default
ultrasonic time).
2. Time setting: Press the “TIME-/TIME+ ”shortly at a time means time increase/reduce
1min at a time, press and hold means time will increase/reduce by 10mins continuously. The
cleaning stops when the timer counts down to 00:00. If the unit needs to be stopped before the
timer runs up, press “Ultrasonic” button.
3. Temperature setting: Press “temperature-/temperature+”shortly at a time means
time increase/reduce 1℃ at a time, press and hold there means time will
increase/decrease by 10℃ .
Note: Usually, the best cleaning temperature is within 40℃ to 60℃. The temperature
displayed is the real temperature. The default value of the temperature is 0℃. When you set
temperature, the heating function can not be started unless the set temperature is higher
than the environmental temperature and the “Heating” button is pressed after the
temperature setting. When the real temperature is higher than the set temperature, the
indicator of heating will turn off. However, the heating function would not be turned off
automatically if the ultrasonic cleaning still works, it will start again when the water
temperature is lower than the set temperature. In this case, you can only press “Heating” to
turn off heating function. However, if the ultrasonic cleaning time runs out, the heating
function will stop automatically.
4. After time and temperature setting, press “Ultrasonic” or ”Heating” button to start both
functions. Press “Ultrasonic” or ”Heating” button again, the Ultrasonic or heating function
will stop.

5. Power Controller: the power can be adjusted among 0% and 100%. Users can adjust the
power value randomly based on the characters of the stuffs to be cleaned.
6. Empty the tank and clean both the outside and inside of the cleaner with a clean and dry
cloth for next use.
Attention
1) In the process of cleaning, any loose tesseras may fetch way.
2) Please don’t clean any cloth, leather, wooden stuffs which would fade easily via this machine.
3) Please don’t clean cellphones, watches which is not water-proof via this machine.
4) Please don’t clean any shells, glass brackets which is made with hawksbill etc via this
machine.
5) While the machine is working normally, the syntony of the ultrasonic wave and tank gives a
well-proportioned sound with no shudder on the surface of the water but sprays generated
by the tiny bubbles. If there are discontinuous surges, please add or reduce a little of
washing solution in the tank to stop the surges, which is good for get a better cleaning
effect.
6) Please don’t make the machine work for a continuous long time (not more than 24 hours) as
possible as you can because a long-time working will raise the temperature of the case,
accelerate the burn-in process of inner electronic components and parts.
7) Please don’t use flammable detergent.
8) This device can not be used by individuals with limited physical knowledge, or the mental
disabled, or those lacking experiences or knowledge, such as children, unless they are
supervised by an individual who can take charge of their safety or have received training in
operating the device .
9) DO NOT operate the unit without fluid in the tank. Always ensure that the fluid is no
higher than the max mark and no lower than the minimum depth of 7cm.
10) Please prevent the cleaning solutions or water from getting into the case or being
splashed on the transducers because it may cause electric leakage and short circuit
or damage the wafers inside the transducers.
11) If something gets into the case, please take it out immediately.
12) When you change or drain the liquid inside the tank, please ensure that the liquid is under
common temperature, and that the ultrasonic function is turned off, and that power switch
is turned off.
13) The more items you place in the cleaning bath, the less cleaning efficient you can
get. Leaving enough spaces among items rather than overlapping them is
recommended.
14) Do keep the lid on during use. This will prevent splashes and reduce evaporation of the
fluid.
15) DO NOT touch the power switch with wet hands.
16) DO NOT disassemble the machine if you are not professional.
17) DO NOT place the device on a soft surface where the vents can be blocked.
18) Take care when adding or removing items from the cleaning tank as the splashed fluid is
likely to be hot and damage the internal components. Any splashed fluid must be dried
immediately.

5
19) Clean the contaminants in the tank and keep the surface of the machine clean after use.
20) In case of emergency or failure to follow the aforementioned items, turn the power switch
off and contact the maintenance staffs.

Ultrasonic cleaning is not recommended to be used to clean the following gemstones: Opal,
Pearl, Emerald, Tanzanite, Malachite, Turquoise, Lapis and Coral.
DIFFERENT WAYS OF CLEANING
Gennral Cleaning—use only water to clean under the temperature of about 50℃;
Enhanced Cleaning—add few drops of standard cleaning solutions, liquid soap, or
detergent, or any other non-acidic cleaning agents.
Extensive Cleaning--removing tarnish, carbon & rust from non-plated metals, it is
recommended to use specific cleaning solution associated with ultrasonic cleaners.
WARNING : Strong acid or alkaline cleaning solution will cause corrosion, rust and
even puncture of tank or machine body. To solve this problem, please dilute the solution
to mild PH or use a special tank made of a specific-graded stainless steel, like SUS304.

6
The cleaning solution will deteriorate in effectiveness over time and use. It is important to
regularly change the fluid and carefully wash the inside of the cleaning tank in order to preserve
the effectiveness and longevity of the cleaner. Do not use corrosive or abrasive cleaning tools
to clean the tank which must be wiped down and dried before it can be re-connected to the
electrical supply.
NOTE: If the machine starts to spark, smoke, smell of burnt electrics or displays any other fault
the operator must immediately stop the machine, and isolate it from the electrical supply and
contact the supplier. It is dangerous to use it after that.
Advantage
Ultrasonic is widely used throughout industries to remove difficult contaminants from the parts
during or after manufacturing process which might require a stage of cleaning before the next
process. In general, if an item can be cleaned with liquid, it can be cleaned much faster and
more thoroughly with an ultrasonic cleaner. Compared with traditional solvent/scrubbing, our
ultrasonic cleaners:
•Are more effective at removing contaminants;
•Are quicker to get a good cleaning effect;
•Save labor time of employees (and subsequent labor cost);
•can heat the cleaning solutions to a suitable cleaning temperature so as to enhance the
cleaning efficiency;
•Have a digital controller of high-precision and a long service-life;
•reduce chemicals in the cleaned stuffs;
•Are environment friendly because of its recyclability.
For Better cleaning effect:
●Make the machine have a proper power density: The higher the power density is, the
better cavitation effect the machine can make, the better cleaning effect we can get, the
faster the cleaning can be finished. For big workpieces, better to choose a big power
density; while for high precision workpieces, better to choose a small power density.
Generally most ultrasonic cleaners have a power density among 12~20W/L.
●Choose a suitable frequency: The lower frequency we choose, the better cavitation we
can get; the higher frequency we choose, the better refraction and reflection we can get.
So for simple surfaces, better to choose a low frequency; while for complicated surfaces
with deep and blind holes, better to choose a high frequency. The common frequencies
are 20KHz, 28KHz, 40KHz, 80KHz, 0.8MHz.

7
●Immerse the cleaned stuffs well into into the water (below the “MAX” mark).
●Add a small amount of cleaning solution.
●Make sure that there is enough space around each stuff in the tank. The more stuffs you
place in the tank, the less efficiency you can get. It is not advised to overlap stuffs
because the ultrasonic cleaning system can not work well with layered stuffs.
●Use a basket. Do not put stuffs directly into the bottom of the tank because that is
harmful for the inner tank. So it is better to use a suitable basket. Especially a metal
basket only absorbs about 8% ultrasonic energy.
●Choose a suitable leaning temperature: The cavitation effect can be the best when the
water is under 40℃～50℃. Generally, the higher the temperature is, the easier the
contaminants get resolvent. However, when the temperature reaches 70℃～80℃, the
cleaning effect also will be affected.
●Set a suitable cleaning time: the longer, the better. (except for stuffs made with special
materials).
