CREWORKS 2L Digital Ultrasonic Cleaning Machine (Model JX-0101S) Instruction Manual

1. Introduction and Overview

The CREWORKS 2L Digital Ultrasonic Cleaning Machine (Model JX-0101S) is designed to provide professional-quality cleaning for a wide array of items. Utilizing advanced ultrasonic cavitation technology, this device generates high-frequency sound waves that create microscopic bubbles in the cleaning solution. These bubbles rapidly implode, producing a powerful scrubbing action that effectively dislodges dirt, grime, rust, tarnish, and other contaminants from even the most intricate and hard-to-reach surfaces. It is ideal for cleaning jewelry, watches, eyeglasses, dental appliances like dentures and retainers, small tools, circuit boards, and various household items.

Equipped with a digital control panel, a powerful heater, and an adjustable timer, this ultrasonic cleaner offers precise control over the cleaning process, ensuring optimal results for different materials and levels of soiling. Its durable 304 stainless steel construction ensures longevity and resistance to corrosion, making it a reliable addition to your home or workshop.

5. Setup

1. Placement: Place the ultrasonic cleaner on a stable, flat, and dry surface, away from heat sources and direct sunlight. Ensure adequate ventilation around the unit.
2. Power Off: Verify that the main power switch located at the back of the unit is in the 'OFF' position.
3. Fill Tank: Open the lid and carefully fill the stainless steel tank with water. For general cleaning, tap water is sufficient. For enhanced cleaning, a specialized ultrasonic cleaning solution or a small amount of mild detergent can be added. Do not exceed the 'MAX' fill line indicated inside the tank.
4. Insert Basket: Place the stainless steel cleaning basket into the tank.
5. Load Items: Gently place the items to be cleaned into the basket. Ensure items are not directly touching the bottom of the tank or overcrowded, as this can impede cleaning effectiveness.
6. Close Lid: Securely close the lid on the unit.
7. Connect Power: Plug the power cord into a grounded electrical outlet.

6. Operating Instructions

1. Turn On: Flip the main power switch at the back of the unit to the 'ON' position. The digital display on the front panel will illuminate.
2. Set Temperature: Use the TEMP+ and TEMP- buttons to adjust the desired cleaning temperature. The recommended temperature range is 20-80°C (68-176°F). Press the ON/OFF button under 'TEMP' to activate the heating function. The 'ACTUAL °C' display will show the current water temperature, which will gradually rise to your set temperature.
3. Set Time: Use the TIME+ and TIME- buttons to set the desired cleaning duration. The timer can be set from 1 to 30 minutes.
4. Start Ultrasonic Cleaning: Once the desired temperature is reached (or if you prefer to clean without heating), press the ON/OFF button under 'TIME' to start the ultrasonic cleaning process. You will hear a buzzing sound, and the 'MINUTES SECONDS' display will begin counting down.
5. Monitor Progress: Do not open the lid or place hands into the tank during operation. The lid helps contain the ultrasonic waves and reduces noise.
6. End Cycle: The unit will automatically stop the ultrasonic cleaning when the timer reaches zero. The heating function will continue to operate until manually turned off.
7. Power Off: After the cleaning cycle is complete, press the ON/OFF button under 'TEMP' to turn off the heater. Then, flip the main power switch at the back of the unit to 'OFF' and unplug the power cord from the outlet.

7. Cleaning Guidelines

General Cleaning (Light Soil)

• Temperature: 50°C (122°F)
• Time: 5-10 minutes
