Specification: Item Type: Ultrasonic Cleaner Model: 340HT Cleaning Tank Capacity: 4.5L Cleaning Tank Size: Approx 300x155x100mm / 11.81x6.1x3.94in Ultrasonic Frequency: 40KHz Ultrasonic Power: 180W Heating Power: 100W Number of Vibration Heads: 3 Working Time Range: 1-20min Temperature Range: 0-80℃ Liner Material: SUS304 Shell Material: Stainless Steel Net Basket: Equipped Noise Reduction Lid: Equipped FAQ: Q: What is an ultrasonic cleaner? A: 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. Q: Which products can this ultrasonic cleaner clean? A: Many products can be cleaned. Common such as glasses, necklace, earring, bracelet, electronic, watch, false tooth, printer ink head, shaver head, nib, coin, badge, nipple, etc. Q: Which detergents can be properly added for better cleaning during the cleaning process? A: You can add cleaning liquid or abluent, such as: cleanser essence, soapy water, disinfectant, etc. However, do not add acid or alkaline solution to the machine to prevent ABS from corrosion and damage. Package List: 1 x Ultrasonic Cleaner1 x English Manual1 x Power Cord Note: 1. When the ultrasonic wave is in normal operation, the uniform resonance sound of the ultrasonic wave and the tank body should be heard, and the surface of the cleaning liquid is not excited, only the ripple caused by the hole blasting. If there is intermittent oscillation, please add a little cleaning liquid or discharge a little cleaning liquid. Eliminating the oscillations helps to clean the objects;2. Under the premise of ensuring that the cleaning objects are clean, work as intermittently as possible and not heat, because the heating and long-time ultrasonic work will increase the temperature inside the chassis, and it is easy to accelerate the aging of the electronic device;3. Never use flammable and corrosive detergents;4. When there is no proper amount of cleaning liquid in the cleaning tank, the heating and ultrasonic wave must not be turned on;5. Prevent the cleaning fluid and water from entering the chassis, soaking the circuit board and the vibrator, which will burn the electronic components;6. If any foreign object falls into the bottom of the tank, it should be taken out immediately (not directly taken by hand to prevent injury);7. When changing liquid or draining, it should be carried out in the tank at normal temperature, and be sure to turn off the power and unplug the power cord (After cleaning, do not leave liquid in the cleaning tank )8. Keep the appearance of the machine clean when cleaning; clean the machine after stopping, keep the whole machine clean and dry;9. Everytime working time should not be too long. It should be stopped for five minutes after 15 minutes of power-on to better protect the machine and reduce the failure rate.
