1. Important Safety Instructions
Please read and understand all safety instructions before operating the CREWORKS Ultrasonic Cleaner. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Do not disassemble: Never attempt to open or repair the unit yourself. Refer all servicing to qualified personnel.
- Do not use unattended: Always supervise the unit during operation.
- Always use sufficient fluid: Ensure the cleaning tank is filled with an appropriate amount of cleaning solution before turning on the unit. Operating without fluid can damage the transducer.
- Unplug before filling & draining: Always disconnect the power cord from the outlet before adding or removing cleaning solution from the tank.
- Electrical Safety: Do not immerse the main unit in water or other liquids. Keep the power cord away from heated surfaces.
- Heat Safety: The heating function can make the tank and solution hot. Exercise caution to prevent burns.
- Ventilation: Operate the unit in a well-ventilated area, especially when using certain cleaning solutions.

2. Product Overview
The CREWORKS 2L Digital Ultrasonic Cleaner utilizes high-frequency sound waves to create cavitation bubbles in a liquid, providing thorough cleaning for various items. It features a digital control panel for precise settings, a heating function, and specialized modes for optimal cleaning.
2.1 Components
- Main Unit: Houses the ultrasonic transducer, heating element, and control circuitry.
- Stainless Steel Tank: 2-liter capacity, made from durable 304 stainless steel.
- Lid: Helps contain sound and prevent evaporation.
- Cleaning Basket: Designed to hold items during cleaning, preventing them from resting directly on the tank bottom.
- Power Cord: For connecting the unit to an electrical outlet.
2.2 Key Features
- Digital Control Panel: Intuitive interface for setting time and temperature.
- Degas Mode: Removes dissolved gases from the cleaning solution, enhancing cavitation efficiency and preventing oxidation.
- Gentle Mode: Reduces ultrasonic power for cleaning delicate items, protecting fragile surfaces.
- Heating Function: Accelerates the cleaning process by warming the solution (adjustable from 68°F to 176°F).
- Timer: Adjustable cleaning cycles up to 99 minutes.
- Durable Construction: 304 stainless steel tank and basket for longevity and corrosion resistance.

This image illustrates the key internal and external features of the ultrasonic cleaner, including the user-friendly digital control panel, the robust stainless steel tank, safety fuses, and ventilation holes for reliable performance.

This graphic demonstrates the robust construction of the cleaning tank, highlighting the use of food-grade 304 stainless steel for durability, corrosion resistance, and a thickness of 0.04 inches.
3. Setup
- Unpack: Carefully remove the ultrasonic cleaner and all accessories from the packaging. Inspect for any damage.
- Placement: Place the unit on a stable, level, and dry surface. Ensure adequate ventilation around the unit.
- Fill Tank: Ensure the unit is unplugged. Fill the stainless steel tank with an appropriate cleaning solution. The liquid level should be between the MIN and MAX marks (if present), or at least cover the items to be cleaned. Do not overfill.
- Connect Power: Plug the power cord into a grounded electrical outlet.
4. Operating Instructions
The digital control panel allows for precise control over cleaning parameters.
4.1 Control Panel Overview
The control panel features digital displays for temperature and time, along with buttons for power, temperature adjustment, Degas mode, Gentle mode, and time adjustment.
- Power Button: Turns the unit on/off.
- TEMP Button: Activates/deactivates the heating function. Use the up/down arrows to adjust the target temperature.
- DEGAS Button: Activates the Degas mode.
- GENTLE Button: Activates the Gentle mode.
- TIME Button: Activates/deactivates the ultrasonic cleaning function. Use the up/down arrows to adjust the cleaning duration.
4.2 Basic Operation
- Prepare Items: Place items to be cleaned into the cleaning basket. Ensure items are not touching each other or the bottom of the tank directly.
- Place Basket: Carefully lower the basket with items into the cleaning solution.
- Power On: Press the Power button to turn on the unit.
- Set Temperature (Optional): If heating is desired, press the TEMP button and use the up/down arrows to set the target temperature (68°F to 176°F). The unit will begin heating. Allow time for the solution to reach the desired temperature.
- Degas the Solution (Recommended): For optimal cleaning, especially with fresh solution, press the DEGAS button. This removes air bubbles from the solution, improving cavitation. Run Degas mode for 5-10 minutes.
- Set Cleaning Time: Press the TIME button and use the up/down arrows to set the desired cleaning duration (1 to 99 minutes).
- Start Cleaning: The ultrasonic cleaning will start automatically after setting the time. The timer will count down.
- Gentle Mode (Optional): If cleaning delicate items, press the GENTLE button to reduce the ultrasonic intensity. This can be activated before or during a cleaning cycle.
- End of Cycle: The unit will stop automatically when the timer reaches zero.
- Remove Items: Unplug the unit. Carefully lift the basket out of the tank. Rinse cleaned items with clean water and dry them thoroughly.

This image illustrates how Degassing Mode removes gases from the tank to prevent oxidation and enhance cleaning, and how Gentle Mode effectively reduces cleaning intensity to protect delicate items by modifying sound pressure waves.
5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your ultrasonic cleaner.
- Draining: Always unplug the unit before draining the cleaning solution. Use the drain valve (if present) or carefully pour out the solution.
- Cleaning the Tank: After each use, rinse the stainless steel tank with clean water. Wipe the interior and exterior with a soft cloth. Do not use abrasive cleaners or scrubbers.
- Exterior Cleaning: Wipe the exterior of the unit with a damp cloth. Avoid getting water into the control panel or electrical components.
- Storage: Store the unit in a cool, dry place with the lid slightly ajar to allow for air circulation.
- Solution Replacement: Replace cleaning solution regularly, especially if it becomes visibly dirty or its cleaning effectiveness diminishes.
6. Troubleshooting
