What's in the Box
Upon unpacking, verify that all components are present and undamaged:
- 1 x Ultrasonic Cleaner Unit
- 1 x Stainless Steel Basket
- 1 x Power Cord
- 1 x User Manual (this document)
Setup
- Placement: Place the ultrasonic cleaner on a firm, level, and dry surface, away from direct sunlight and heat sources. Ensure adequate ventilation around the unit.
- Power Connection: Connect the power cord to the unit and then to a grounded electrical outlet. Ensure the power switch on the back of the unit is in the OFF position before plugging in.
- Filling the Tank: Open the lid and fill the stainless steel tank with an appropriate cleaning solution. The liquid level should be between the MIN and MAX marks, ensuring items to be cleaned are fully submerged but not overflowing. Do not operate the unit without liquid in the tank.
- Inserting Items: Place items to be cleaned into the stainless steel basket. Lower the basket gently into the tank. Avoid direct contact of items with the tank bottom to ensure optimal cavitation.

Operating Instructions
- Power On: Flip the main power switch located on the back of the unit to the ON position. The digital display will illuminate.
- Set Temperature: Press the "TEMP" button to adjust the desired cleaning solution temperature. Use the up/down arrows to set the temperature between 68°F and 176°F (20°C and 80°C). The unit will begin heating automatically.
- Set Timer: Press the "TIME" button to adjust the desired cleaning duration. Use the up/down arrows to set the timer for up to 30 minutes.
- Start Cleaning: Once temperature and time are set, the ultrasonic cleaning process will begin. The display will show the remaining time.
- During Operation: The unit will produce a slight humming sound and visible cavitation bubbles. This is normal. Avoid touching the tank or solution during operation.
- End of Cycle: The unit will automatically stop when the timer reaches zero.
- Remove Items: Carefully lift the basket out of the tank. Rinse the cleaned items under clean water and dry them thoroughly.

Maintenance
- Draining the Tank: After each use, especially if the solution is dirty, unplug the unit and drain the liquid using the built-in drain valve. Tilt the unit slightly towards the drain for complete emptying.
- Cleaning the Tank: Rinse the stainless steel tank with clean water. Wipe the interior and exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or immerse the main unit in water.
- Storage: Store the unit in a cool, dry place when not in use. Ensure the tank is completely dry before storage.
- Fuse Replacement: In case of power issues, check the fuse located near the power inlet. Replace with a fuse of the same rating if necessary. (Note: Refer to the product's electrical specifications for fuse type and rating).
