Cleaning Procedure

1. Add Items: Place the items to be cleaned into the cleaning basket. Ensure items are fully submerged in the cleaning solution but do not overcrowd the basket.

   • For delicate items (e.g., circuit boards, Invisaligns, fragile jewelry), press the GENTLE button to reduce the ultrasonic intensity.
5. Set Time: Use the TIME ▲/▼ buttons to set the desired cleaning duration. The recommended cleaning time varies depending on the item and level of dirt.
6. Start Cleaning: The unit will automatically start the ultrasonic cleaning process once the temperature and time are set. The timer will count down.
7. Completion: Once the timer reaches zero, the ultrasonic cleaning will stop automatically.
8. Remove Items: Carefully lift the basket out of the tank. Rinse the cleaned items under clean water and dry them thoroughly.
