Basic Operation:

1. Power On: Press the main power switch (usually located at the back or side) to turn on the unit. The digital display will illuminate.
2. Set Temperature: Press the 'TEMP' button and use the '+' and '-' buttons to set the desired cleaning solution temperature (0-80°C). Press 'SET' to confirm. The heating element will begin to warm the solution.
3. Set Timer: Press the 'TIME' button and use the '+' and '-' buttons to set the desired cleaning duration (1-30 minutes). Press 'SET' to confirm.
4. Place Items: Carefully place the items to be cleaned into the stainless steel basket. Lower the basket into the tank, ensuring items are fully submerged but not touching the bottom of the tank. Close the lid.
5. Start Cleaning: Press the 'ON/OFF' button to start the ultrasonic cleaning process. The timer will begin counting down.

Special Modes:

• Degas Mode: Press the 'DEGAS' button. This mode quickly removes dissolved gases from the cleaning solution, which can improve the efficiency of ultrasonic cavitation, especially with fresh solutions or porous items.
• Gentle Mode: Press the 'GENTLE' button. This mode reduces the ultrasonic power by half, providing a less intense cleaning action suitable for delicate items such as circuit boards, Invisalign aligners, or fragile jewelry, preventing potential damage.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your ultrasonic cleaner.

1. Empty and Clean Tank: After each use, especially with cleaning solutions, drain the tank using the drain valve (if present) or by carefully pouring out the liquid. Rinse the tank with clean water and wipe it dry with a soft cloth.
2. Exterior Cleaning: Wipe the exterior of the unit with a damp cloth. Do not use abrasive cleaners or immerse the unit in water.
3. Storage: Store the unit in a cool, dry place with the lid closed to prevent dust accumulation.
4. Solution Replacement: Replace cleaning solutions regularly, especially if they become visibly dirty or lose effectiveness.
