3. Package Contents
Verify that all items are present and in good condition:
- CREWORKS 15L Ultrasonic Cleaner Unit
- Stainless Steel Cleaning Basket
- Stainless Steel Lid
- 34 fl oz Ultrasonic Cleaning Solution (1:10 Dilution)
- Power Cord
- User Manual (This document)
4. Setup
- Placement: Place the ultrasonic cleaner on a stable, level, and dry surface. Ensure adequate ventilation around the unit.
- Fill the Tank: Open the lid and fill the stainless steel tank with water. For optimal cleaning, use distilled or deionized water. Do not exceed the "MAX" fill line.
- Add Cleaning Solution: Dilute the provided 34 fl oz Ultrasonic Cleaning Solution with water at a 1:10 ratio. For example, for every 1 part of cleaning solution, add 10 parts of water. Pour the diluted solution into the tank.
- Connect Power: Plug the power cord into a grounded electrical outlet.

5. Operating Instructions
- Prepare Items: Ensure items to be cleaned are suitable for ultrasonic cleaning. Remove any loose debris or large particles before placing them in the basket.
- Place Items: Carefully place the items into the stainless steel cleaning basket. Lower the basket into the tank, ensuring items are fully submerged in the cleaning solution but not touching the bottom of the tank directly.
- Set Temperature: Turn the "TEMPERATURE" knob to set the desired cleaning temperature. The unit can heat up to 176°F (80°C). Heating helps to loosen grime and improve cleaning efficiency. The "HEATING" indicator light will illuminate.
- Set Time: Turn the "TIME" knob to set the desired cleaning duration. The timer can be set for up to 30 minutes. The "CLEANING" indicator light will illuminate when the ultrasonic function is active.
- Start Cleaning: The unit will begin the ultrasonic cleaning process once the timer is set. The cavitation bubbles generated will dislodge dirt, grime, and other contaminants from the items.
- Monitor Progress: For heavily soiled items, multiple cleaning cycles or pre-soaking may be necessary.
- End Cycle: Once the set time has elapsed, the unit will automatically stop. The indicator lights will turn off.
- Remove Items: Carefully lift the basket out of the tank. Rinse the cleaned items with clean water to remove any residual solution or dislodged debris. Dry thoroughly.
5.1. Understanding Ultrasonic Cleaning (Cavitation)
The CREWORKS Ultrasonic Cleaner utilizes high-frequency sound waves (40 kHz) to create microscopic bubbles in the cleaning solution. These bubbles rapidly form and collapse (cavitation), generating powerful scrubbing action that dislodges contaminants from surfaces, even in intricate areas. This process is highly effective for removing dirt, tarnish, carbon, and other residues without harsh chemicals or abrasive scrubbing.

5.2. Using the Cleaning Solution
The included CREWORKS Heavy Duty Cleaner & Degreaser is a concentrated solution designed for use with ultrasonic cleaners. It is suitable for most metals, alloys, and plastics. Always dilute it with water at a 1:10 ratio (1 part solution to 10 parts water) before use. This ensures effectiveness and extends the solution's lifespan.

6. Maintenance
- Draining the Tank: After each use, especially when the solution is visibly dirty, unplug the unit. Allow the water to cool to room temperature. Use the built-in drain valve (if available on your model) or carefully pour out the used solution.
- 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 scouring pads.
- Storage: Store the ultrasonic cleaner in a cool, dry place with the lid closed to prevent dust accumulation.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | No power supply; unit not plugged in. | Check power cord connection and outlet. Ensure unit is properly grounded. |
| No ultrasonic action. | Insufficient fluid in tank; timer not set. | Ensure fluid level is above MIN mark and below MAX. Set the timer. |
| Poor cleaning results. | Incorrect solution dilution; items too dirty; incorrect temperature/time. | Verify 1:10 solution dilution. Pre-clean heavily soiled items. Adjust temperature and time as needed. Use appropriate cleaning solution for item type. |
| Unit is overheating. | Running without sufficient fluid; prolonged use. | Ensure proper fluid level. Allow unit to cool down between extended uses. |
