Thank you for purchasing this ultrasonic cleaner. Please take some time to
read these operating instructions before use and keep them for future
reference. Failure to follow these instructions may lead to serious damage to
the product.
ULTRASONIC PRINCIPLE
Ultrasonic cleaning is based on the cavitation effect caused by high frequency
ultrasonic wave vibrations in the fluid. Microscopicbubbles are formed, and
then implode violently causing the cavitation which create an intense
scrubbing action on thesurface 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. 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
components.
PREPARATION:
-
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 lead
d: Outlet filter
e: Mesh basket (Optional)
f: Manual -
Place the cleaner on a flat, clean surface and ensure that the cooling fan will get adequate ventilation, that all controls are set to off, and the drain tap is closed.
-
Ensure that the power lead is securely plugged into the cleaner, and that no part of the lead is likely to contact with moisture.
-
Carefully fill at least 7cm depth of the tank with a solvent solution. Based on cleaning requirements, we recommend using a small amount of cleaning solution because this will help increase the cleaning performance. Now the cleaner is ready for use.
Attention
A) 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 spraysgenerated 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 achieve a bettercleaning effect.
B) Please don’t use the machine for a continuous long period (not more than 60
minutesas this can raise the temperature of the case and accelerate the burn-
in process of internelectronic components.
Keep away from children!
This device cannot 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.
Please read the following items very carefully as failure to comply with
them may invalidate your warranty.
- DO NOT run the cleaner continuously for more than one hour at a time because it can damage the internal components.
- 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.
- DO NOT drop any item into the tank because it may damage the transducer. Always place items gently into the tank and use the basket whenever possible.
- The more items you place in the cleaning bath, the less cleaning efficiency you can expect. Leaving enough space between items rather than overlapping them is recommended.
- Do keep the lid on during use. This will prevent splashes and reduce evaporation of the fluid.
- Never immerse the machine or power cord in water or other liquid.
- DO NOT touch the power plug with wet hands, especially when inserting or removing the plug.
- DO NOT touch the unit if the machine has fallen into water during operation. Remove the power plug from the socket first.
- DO NOT disassemble the machine if you are not a professional repairer.
- UNPLUG the power source while filling or emptying the tank.
- DO NOT spray water or liquid over the device and the control panel.
- DO NOT operate the cleaner without proper grounding.
- DO NOT place the device on a soft surface where the vents can be blocked.
- Always turn the heater off after using as leaving it on can make the fluid evaporate and damage internal components.
- Take care when adding or removing items from the cleaning tank as the splashed fluid is likely to be hot and may damage internal components. Any splashed fluid must be dried immediately.
- In case of emergency or failure to follow the aforementioned items, disconnect the mains supply by removing the plug from the mains socket.

OPERATION
-
Fill the stainless steel tank with cleaning solution; Plug the power lead into grounded outlet; After power-on, the temperature displays the actual environmental temperature, LED displays 3 minutes (default ultrasonic time).
-
Time setting: Press the “TIME+/TIME- ”shortly at a time means time increase/reduce 1min at a time, press and hold time switch continuously will increase/reduce by 10mins. The cleaning stops when the timer counts down to 00:00. If the unit needs to be stopped before this, press the “Ultrasonic frequency” button.
NOTE: Do not run the cleaner continuously for more than one hour -
Temperature setting: Press “temperature+/temperature-” shortly at a time means time increase or reduce 1℃ at a time, press and hold time switch continuously will increase/reduce by 10℃ . Usually, the best cleaning temperature is within a 40℃ to 60℃ range.
-
After time and heat setting, press “Heating” or “ultrasonic” button to start both function. If press the “ultrasonic “ again , the ultrasonic function will stop , and the heating function will stop at the same time. If you want to keep heating, press the “ heating” button again.
-
Degas mode: work intermittently，i.e., 6s “ON” + 2s “OFF” working mode. It can clean items deeply and efficiently.
-
Empty the tank and clean both the outside and inside of the cleaner with a clean and dry cloth for the next use.
NOTE: Do not pour water out until it’s cooled, because of hot water may injure you and also empty burn will damage the machine itself.
DIFFERENT WAYS OF CLEANING
General 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.
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,
isolate it from the electrical supply and contact the supplier. It is
dangerous to use it after that.
WARNING : Strong acid or alkaline cleaning solution will cause corrosion,
rust and even puncture the 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, For example: use SUS304 tank.
Advantages
Ultrasonic cleaning is widely used throughout industry 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,
ultrasonic cleaners:
- Are more effective at removing contaminants;
- Are quicker to achieve a good cleaning effect;
- Save labour 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;
- Are environment friendly because of its recyclability.
For Better cleaning effect:
- Immerse the items to be cleaned well into the water.
- Add a small amount of cleaning solution. To remove grease, a degreaser is ideal. For carbon deposits, we recommend a specialized ultrasonic cleaning powder.
- Make sure that there is enough space around each item in the tank. The more items you place in the tank, the less efficiency you will achieve. It is not advised to overlap items because the ultrasonic cleaning system cannot work well with layered items.
- Use a basket. Do not put items directly into the bottom of the tank because that is harmful for the inner tank. Especially a metal basket as it only absorbs about 8% ultrasonic energy.
- Choose a suitable temperature: Generally, the higher the temperature is, the better cleaning effect of the ultrasonic cleaner. However, when temperature exceed 70℃～80℃, cleaning effect will be reduced. So the best temperature range we suggest is 40℃～60℃.
