The principle of ultrasonic cleaning is that millions of tiny air bubbles are generated within a liquid by high frequency vibration. The air bubbles burst when in contact with an object and dislodge the debris to achieve the cleaning effect.

For most cases, using tap water is sufficient. Purified water or distilled water has the same cleaning effect as regular tap water. Special solutions are not necessary in most cases. However, when cleaning silver or copper items where oxidation has darkened them, special solutions such as SeaClean2 need to be added to the water to remove the oxidation.

Please observe the following child safety precautions:

• Keep it away from children!

• This appliance can be used by children aged from 8 years and above if they have been given supervision or instruction concerning use of the appliance in a safe way and if they understand the hazards involved.

• If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid a hazard.

Risk of fire and explosion!

• Never use flammable liquids or solvents directly in the ultrasonic cleaning bath. Alcohol, acids and solvents should be used in an In-direct tank.

• Ultrasonic activity increases the vaporisation of liquids and creates a very fine mist which can catch fire.

Caution!

• Avoid any acetone, acid, alcohol, ammonia or solvents from contacting the plastic housing and control panel to prevent corrosion. Use Indirect Cleaning and a glass or metal container for using such solutions.

Risk of damage to the ultrasonic tank!

• Do not use any acid cleaning agents (pH value < 7) directly in the stainless steel tank if the cleaning items or the contamination of the cleaning items contain halogenides (fluorides, chlorides or bromides). The same applies to NaCl solutions.

• The stainless steel tank can be destroyed by crevice corrosion in a very short time. Substances that cause crevice corrosion can be contained in household cleaners.

Other observations:

• Do not operate the product without filling the tank with water. Running dry will damage the unit.

• Do not plug in the power cord before adding water to the tank. To avoid overspill, do not fill the tank above the ‘Max’ line.

• Do not use solution containing abrasive substances or strong corrosive chemical solution not recommended by the manufacturer or the supplier.

• Place the device on a dry and flat surface for operation.

• When the device is subjected to severe electromagnetic interference, it may malfunction, stop operating or lose control functions. If this happens, unplug the power cord then re-insert it to restart the device.

When cleaning heavily soiled or greasy items, or items made of silver, copper or brass, chemical solutions are often added to the water. These solutions can form small droplets that take a long time to dissolve. Similarly, newly added water may have many air bubbles on the tank walls. Both droplets and air bubbles can reduce the cleaning effect in the initial phase of ultrasonic cleaning.

The Degas function is designed to address this. Turning on the degas function will dissipate the droplets and air bubbles, usually in about 90 seconds, which improves the overall cleaning efficiency.

This method only requires tap water and is suitable for jewellery makers, optical labs, biology/chemical labs, homes, and speech therapy clinics.

1. Put the items to be cleaned inside the basket and place the basket inside the tank.

2. Add water to the cleaning tank to a level between the “MIN” and “MAX” lines and ensure it covers the area to be cleaned.

3. Turn the power switch on. Press the Time button to set the timer to 5 – 10 minutes. Press the On/Off button to start cleaning.

Notes on using the basket:

1. The basket reduces friction between items and the tank, but a plastic basket absorbs about 30% of ultrasonic energy, which reduces the cleaning effect.

2. During cleaning, dirt will come off like smoke, and the water will become murky. When the “smoke” effect stops, the cleaning is generally complete.

Indirect cleaning involves putting items in a separate container within the main tank. It’s suitable for medical instrument sterilisation rooms, precision electrical parts manufacturers, watch service shops, and printing shops. Different fluids are used in the container depending on the application (e.g., watch oil, special solution, hexane, pure alcohol, acetone).

Cleaning Method:

1. Put the item inside a separate container. Add the proper fluid to submerge the area to be cleaned.

2. Place the container directly into the main tank. Add water to the main tank to a level between “MIN” and “MAX”, ensuring it does not overflow.

3. Turn the power switch on. Press the Time button to set the timer to 10 minutes. Press the On/Off button to start cleaning. The ultrasonic waves will penetrate the container and clean the items inside.

Selection of container:

• Plastic containers: Absorb about 30% of ultrasound energy and reduce cleaning effect.

• Aluminum containers: Absorb about 20% of ultrasonic energy.

• Stainless steel containers: Absorb about 8% of ultrasonic energy. An optional stainless steel indirect cleaning tank is available for this model.

This method is for debris accumulated over a long period, or for greasy or heavily soiled items. It is suitable for metal processing, jewellery makers, hardware manufacturers, shooting clubs, homes, golf clubs, and automotive repair shops.

1. Large items can be put in the tank directly. Small items can be put in the basket then in the tank. Do not stack items on top of each other to avoid rubbing.

2. Add water to a level between “MIN” and “MAX” and above the area to be cleaned.

3. Add 50 ml (3 tablespoons) of dishwashing liquid.

4. Turn the power switch on. Press the Temp button to set the water temperature to 45°C (113°F). Press the Heater button to turn on the heater. Close the lid. The heater will turn off when the set temperature is reached.

5. Press the Time button to set the timer to 15 minutes. Press the On/Off button to start cleaning. Grease will dissipate and appear like black smoke in the water.

6. When the cycle stops, open the drainage valve to release the dirty water. Close the valve afterwards.

7. Clean the tank and add fresh water. Wash the items for another 3 minutes to remove the residual debris and detergent.

This method is for silver, copper, or brass items with oxidation that has darkened them. It is suitable for silver/copper/brass product manufacturers, homes, and shooting clubs.

1. Put the items in the basket and then in the tank. Add water to a level between “MIN” and “MAX” and above the area to be cleaned.

2. Add a special solution (like SeaClean2) according to the recommended ratio (typically 1:10).

3. Turn the power switch on. Press the Temp button to set the water temperature to 50°C (122°F). Press the Heater button to turn on the heater. Close the lid. The heater will turn off when the set temperature is reached. The heater has dual protection and will turn off automatically after 50 minutes.

4. Press the h/min button to set the solution usage time. A common time is 0:40 or 1:00. Refer to the solution manufacturer’s instructions.

5. Press the Time button to set the timer to 15 minutes.

6. Press the Function button to select the degas function. Press On/Off to start degassing. After 90 seconds, it will automatically switch to normal cleaning.

7. When it is done, remove the basket and the items. Rinse the items with tap water or follow steps 6 and 7 in the Enhanced Cleaning section.

1. Remove the cover and place it on the cover holder vertically. Put items in the basket then put them in the cleaning tank. Add water to a level between “MIN” and “MAX” and above the area to be cleaned. If the unit is turned on without water for over 15 seconds, it may be damaged.

2. Connect the power cord to an outlet and turn the switch on. The LED display will show 05:00. Adjust the timer if needed using the Time button. Common cleaning times are 5, 10, or 15 minutes.

3. Press the On/Off button to start cleaning. A buzzing sound will be heard. Closing the lid reduces noise. The digital timer will count down. When it displays 00:00, cleaning is done. To stop at any time, press On/Off. The unit has overheating protection; if the red light is on, allow it to cool for about 20 minutes until the green light comes on.

4. Select one of the 4 cleaning methods. If heating is needed, press the TEMP button to select a temperature and press the Heater button. The unit has dual protections and the heater will turn off automatically after 50 minutes. The thermometer lights will indicate the percentage of the set temperature reached.

5. When cleaning is complete, switch off the power, open the lid, and retrieve the basket and items. Connect the hose to the drainage pipe, open the drainage valve to drain the dirty water, clean and wipe the tank dry, then close the drainage valve.

1. Do not turn on the unit without water in the tank. Even with multiple protections, running it for over 30 seconds without water may damage the unit or severely reduce its life. Heating for over 3 minutes without water will damage the heater.

2. Do not run the unit for extended time or continuously. The unit has overheat protection. If it has been running for 45 minutes, it is recommended to stop it for about 20 minutes to prolong its life.

3. Do not keep water in the cleaning tank for a long time. After cleaning is complete, open the drainage valve to drain the dirty water. Clean and wipe the tank dry.

4. Do not spray water over the housing. Use a towel to wipe the tank and the housing dry. Avoid contact with acetone, acid, alcohol, ammonia, or solvents on the plastic housing and control panel to prevent corrosion.

5. Do not expose the unit under direct sunshine for a long time. Keep the unit in a dry, cool, and ventilated area.

PLASTIC BASKET

The basket has foldable handles. After cleaning, it can be raised and suspended above the water using the handles to allow items to drain.

BEAKER AND BEAKER HOLDER – INDIRECT CLEANING

Put the beaker holder and beaker(s) (optional accessory) across the main cleaning tank. Add water to the main tank so the water level reaches the beaker(s). Add the required solution into the beaker(s). This can be used to clean small items such as dental burs, files, and nozzles.
