6. Operating Instructions

Follow these steps for effective cleaning:

1. Prepare Items: Place the items to be cleaned into the cleaning basket. For heavily soiled items, pre-soaking may be beneficial.
2. Place Basket: Carefully lower the cleaning basket with items into the tank, ensuring items are fully submerged but not touching the bottom of the tank directly.
3. Set Temperature (if applicable): Use the temperature controls on the digital display to set the desired cleaning temperature. Allow time for the liquid to heat up.
4. Set Cleaning Time: Use the timer controls on the digital display to set the desired cleaning duration. Cleaning times vary based on the item and level of dirt.
5. Select Frequency (40kHz/33kHz): Choose the appropriate ultrasonic frequency for your cleaning task. 40kHz is generally suitable for delicate items and general cleaning, while 33kHz may offer more powerful cleaning for robust items.
6. Activate Degassing: If your unit has a degassing function, activate it before starting the cleaning cycle. Degassing removes dissolved gases from the cleaning solution, which can improve ultrasonic cleaning efficiency.
7. Start Cleaning: Press the start button to begin the ultrasonic cleaning cycle.
8. Monitor Progress: The digital display will show the remaining time and current temperature.
9. Completion: Once the cycle is complete, the unit will stop automatically.
10. Remove Items: Carefully lift the cleaning basket from the tank. Rinse the cleaned items with clean water and dry them thoroughly.

• Cleaning the Tank: Rinse the tank with clean water. Wipe the interior and exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or harsh chemicals.
• Storage: Store the unit in a cool, dry place when not in use. Ensure the tank is completely dry before storage.
