• To power the appliance, use only the included adapter.
• To power the appliance, use only safe low voltage in accordance with the type plate.
• If the adapter is damaged, it must be replaced by the manufacturer, its service technician, or a similarly qualified person to prevent dangerous situations.
• Never use the appliance if its adapter or plug is damaged, if it does not work properly, or if it has fallen and been damaged. In such cases, take the appliance to a specialized service for safety and proper function checks.
• Always unplug the appliance from the power supply by pulling the adapter out of the socket when refilling the tank or installing it back onto the appliance.
• The appliance is intended for home use and similar environments (shops, offices, hotels, motels, B&Bs). It is not intended for commercial use.
• Never use or touch the appliance or adapter with wet hands or feet.
• Never immerse the appliance in water (even partially).
• Do not attempt to refill the humidifier without first unplugging the unit from the electrical outlet.
• Do not let water vapor escape directly onto a wall or other water-absorbing surfaces. Humidity may cause damage, especially to wallpaper.
• While in operation, never tilt or try to empty the appliance.
• When cleaning or putting away, switch off the appliance and always pull out the plug from the socket (pull the plug, not the cable) if the appliance is not being used.
• Never throw or place any objects into the openings. Do not place hands, face, or body on or near the water vapor outlet. Do not cover the water vapor outlet or place anything on it when the appliance is running.
• Always place the appliance on a hard, flat surface, at least 2 meters from furniture, water-absorbent surfaces, and electrical devices. Place a water-resistant pad under the diffuser. Never place the appliance on surfaces that could be damaged by water or moisture (e.g., wood, bamboo, painted surfaces).
• Do not direct the water vapor outlet towards walls or water-absorbent surfaces. Moisture can cause damage, especially to wallpaper.
• Do not tilt or attempt to empty the appliance while it is operating.
• Excessive humidity in the room can cause condensation on windows, furniture, walls, and cooler objects. If this happens, switch off the appliance.

• Never leave water in the tank when the appliance is not in use. Clean and dry the water tank before storing. Clean the humidifier thoroughly before the next use.
• For daily use, clean the tank regularly, at least every 3 days. Remove any deposits and limescale (see Chapter IV. MAINTENANCE).
• ⚠️ WARNING: Microorganisms present in water or the environment can multiply in the tank and, if dispersed into the air, can cause serious health risks if water is not changed and the tank is not regularly cleaned every 3 days.
• While the appliance is operating, do not touch the water (fragrant solution) or any components in the water with any part of your body.
• Do not scrape the transducer with hard objects.
• Do not use the appliance in high humidity environments, such as bathrooms.

• The power cord must not be damaged by sharp or hot objects, open fire, or be immersed in water or bent over sharp edges.
• If an extension cord is needed, ensure it is undamaged and complies with valid standards.
• For safety and proper function, use only original spare parts and manufacturer-approved accessories.
• Use this appliance only for its intended purpose as described in this manual. Never use it for any other purpose.
