The humidifier will not filter water and may overheat, causing a fire hazard. • Do not use your humidifier outdoors. • Keep your humidifier away from water, and wet or damp areas. Never place in water or liquid. • Do not use in excessively humid areas. • Keep your humidifier away from heat sources. • Do not use where combustible gases, vapors, metallic dust, aerosol (spray) products, or fumes from industrial oil are present. • Keep 5 ft / 1.5 m away from where oxygen is being administered. • Children should be supervised to ensure that they do not play with the humidifier. • Do not allow children to play with the plastic packaging. Immediately discard the plastic after unwrapping the wick filters. • Do not place anything into any opening on the humidifier. • Children should be supervised to ensure they do not insert fingers or objects into the vent openings. • Do not sit or place heavy objects on the humidifier. • Do not add essential oils, supplemental water treatment liquids, To reduce the risk of fire, electric shock, or other injury, follow all instructions and safety guidelines. General Safety READ AND SAVE THESE INSTRUCTIONS or water filters into the water tank. This will damage the humidifier and cause leaks. • Always unplug your humidifier before servicing (such as changing the filter). • Do not use your humidifier if it is damaged or not working correctly, or if the cord or plug is damaged.

Power Adapter & Cord • Keep the humidifier near the outlet it is plugged into. • Your humidifier’s adapter has a polarized plug (one prong is wider than the other), which fits into a polarized outlet only one way. This is a safety feature to reduce the risk of electric shock. If the plug does not fit, reverse the plug. If it still does not fit, do not use the plug in that outlet. Do not bypass this safety feature. • Never place the adapter near any heat source. • Do not handle the power adapter or plug with wet hands. Keep the plug and power adapter away from liquids. • Do not cover the cord with a rug, carpet, or other covering. Do not place the cord under furniture or appliances. • Keep the cord out of areas where people walk often.
