4. Setup

1. Unpacking: Carefully remove the ultrasonic cleaner from its packaging. Inspect the unit for any signs of damage.
2. Placement: Place the unit on a stable, level, and dry surface. Ensure there is adequate ventilation around the cleaner.
3. Filling the Tank: Open the lid and fill the stainless steel tank with an appropriate cleaning solution. Ensure the liquid level is between the MIN and MAX marks. Do not overfill.
4. Connecting Power: Plug the power cord into a grounded electrical outlet.
5. Loading Items: 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 directly.

5. Operating Instructions

Basic Operation:

1. Power On: Turn the main power switch to the 'ON' position.
2. Set Temperature: Rotate the 'TEMPERATURE' knob to set the desired cleaning temperature between 20°C and 80°C. The 300W heater will begin warming the solution. For faster heating, you may use pre-warmed water.
3. Set Timer: Rotate the 'TIME' knob to set the desired cleaning duration, from 1 to 30 minutes.
4. Start Cleaning: The ultrasonic cleaning will start automatically once the timer is set. The unit will stop when the timer counts down to zero.

Special Modes:

• Degas Function: Activate the 'DEGAS' toggle switch. This function expels air bubbles from the cleaning liquid, maximizing cavitation effectiveness for deeper cleaning. It is recommended to run Degas for a few minutes before starting a cleaning cycle, especially with fresh solution.

• Delicate (Half-Wave) Mode: Activate the 'SEMI-WAVE' toggle switch. This mode modulates the ultrasonic power, providing a gentler cleaning action suitable for fragile items such as delicate jewelry, PCBs, or lenses, preventing potential damage.

After Cleaning:

1. When the cleaning cycle is complete, turn off the unit.
2. Carefully lift the basket out of the tank.
3. Rinse the cleaned items with clean water and dry them thoroughly.
4. Draining the Tank: Place a suitable container under the drain valve. Open the drain valve to empty the cleaning solution. Close the valve once the tank is empty.

6. Maintenance

• Cleaning the Unit: After each use, especially after draining, wipe the inside of the tank and the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
• Basket Care: Clean the stainless steel basket regularly to prevent residue buildup.
• Storage: Store the ultrasonic cleaner in a cool, dry place when not in use. Ensure the tank is empty and dry.
• Regular Checks: Periodically inspect the power cord and plug for any damage. Ensure the drain valve operates smoothly.
