READ AND SAVE THESE INSTRUCTIONS • Only use your air purifier as described in this manual. • Do not use without removing the plastic wrap from the filter. The air purifier will not filter air, and may overheat, causing a fire hazard. • Do not use the air purifier outdoors. • Keep the air purifier away from water, and wet or damp areas. Never place in water or liquid. • Do not use in excessively humid areas. • Keep the air purifier away from heat sources. • Do not use where combustible gases, vapors, metallic dust, aerosol (spray) products, or fumes from industrial oil are present. • At least keep 5 ft / 1.5 m away from where oxygen is being administered. • Supervise children when they are near the air purifier. Do not allow children to play with the air purifier. • Do not place anything into any opening in the air purifier. • Do not sit on or place heavy objects on the air purifier. • Keep the inside of the air purifier dry. To prevent moisture buildup, avoid placing in rooms with major temperature changes or underneath air conditioners. • Always unplug your air purifier before servicing ,cleaning or any other General Safety maintenances(such as changing the filter). • Do not use the air purifier if it is damaged or not working correctly, or if the cord or plug is damaged. Do not try to repair it yourself. Contact Customer Support (see page 22). • This appliance is not intended for used by persons (including children) with reduced physical,sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. • Children should be supervised to ensure that they do not play with the appliance. • Cleaning and user maintenance shall not be made by children without supervision. • WARNING: To reduce the risk of fire or electric shock, do not use this air purifier with any solid-state speed controls (such as a dimmer switch). • Not for commercial use. Household use only. • WARNING:To Reduce The Risk Of Fire, Electric Shock Or Injury To Persons, Do Not Use Replacement Parts That Have Not Been Recommended By The Manufacturer (e.g. Parts Made At Home Using A 3D Printer). 4 • Keep the air purifier near the outlet it is plugged into. • Never place the cord near any heat source. • 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. Place the cord where it will not be tripped over. • If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard. • This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit in a polarized outlet only one way. lf the plug does not fit fully in the outlet, reverse the plug. lf it still does not fit,contact a qualified electrician. Do not attempt to defeat this safety feature. • This air purifier uses standard North American 120V, 60Hz outlets. If using outside the US or Canada, check for compatibility.
