Maintenance and care
• Switch off the unit and disconnect the power plug before each cleaning and maintenance.
• After ultrasonic cleaning, rinse the cleaned parts with running water. Tubes and holes must be blown through well and dried.
• Simple cleaning is done with clear water. For intensive cleaning, a cleaning concentrate is recommended as an additive or a splash of
mild detergent.
• If you touch the sensor button for longer than 3 seconds during ultrasonic cleaning, you can manually switch the unit to stand-by.
• To clean your u-sonic 3, we recommend wiping it with cleaning damp cloths.
