To keep your eta AIRCO 162990000 Ultrasonic Humidifier running smoothly, regular cleaning is key. For frequent use, aim to clean the water tank and the ultrasonic converter at least once a week, as recommended in the user manual. A dirty converter can hinder the humidifier's performance. For routine upkeep, wipe down the exterior surfaces with a damp cloth, rinse the aromatic additive vessel with warm water, and wash the water tank with warm, soapy water. If you choose to use disinfectants, always adhere to the instructions on the product packaging. Avoid harsh cleaning agents like gasoline, glass cleaner, furniture polish, paint thinner, or any solvents, as these can damage the unit. After cleaning, make sure all parts are completely dry before reassembling. For more complex or internal repairs, consulting a professional service provider is advisable. Neglecting the manufacturer's maintenance guidelines may void the warranty.
