Before cleaning, switch off the appliance and unplug it from the mains. Always unplug the unit before cleaning it. Remove the white plastic energy ring from the water tank. Remove the addresser from the water tank by turning it counterclockwise. Any part of the humidifier can be cleaned with a soft damp cloth and dried with a dry cloth. There may be limescale deposits on the ultrasound, particularly if the water in your area is hard. This deposit can reduce the performance of the humidifier; it is therefore recommended to clean it regularly to avoid significant build-up. Regularly clean the humidifier with kitchen degreaser: 1. Spray the kitchen degreaser and gently clean the ultrasound until the deposit disappears. 2. Wipe with a dry cloth and remove residue. 3. DO NOT scrub the ultrasound with hard or abrasive objects, as this can cause damage. 4. DO NOT clean the humidifier with other chemicals.
