WARNINGS

Failure to comply with the warnings listed below may result in electric shock or serious injury.

This product should be used only in accordance with the specifications outlined in this manual. Usage other than what has been specified here may result in serious injury.

When using electrical appliances, basic precautions should always be followed to reduce the risk of fire, electric shock and injury to persons, including the following:

Read all instructions before using appliance.
IMPORTANT – 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. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat this safety feature.
To avoid fire or shock hazard, plug the appliance directly into a 120V AC electrical outlet.
Keep the cord out of heavy traffic areas. To avoid fire hazard, NEVER put the cord under rugs, near heat registers, radiator, stoves or heaters.
To protect against electrical hazards, DO NOT immerse in water or other liquids. Do not use near water.
Children cannot recognize the hazards associated with the usage of electrical appliances. For this reason, always supervise children when they are near the unit.
Always unplug the air purifier before moving it, opening the grill, changing filters, cleaning or whenever the air purifier is not in use. Be sure to pull by the plug and not the cord.
NEVER drop or insert any object into any openings.
DO NOT run cord under carpeting.
DO NOT cover cord with throw rugs, runners, or similar coverings.
DO NOT route cord under furniture or appliances. Arrange cord away from traffic area and where it will not be tripped over.
DO NOT operate any appliance with a damaged cord or plug, if motor fan fails to rotate, after the appliance malfunctions, or if it has been dropped or damaged in any manner. Call Customer Service at 1.866.603.5900 for assistance.
Use appliance only for intended household use as described in this manual. Any other use not recommended by the manufacturer may cause fire, electric shock or injury to persons.
DO NOT use outdoors.
DO NOT place anything on top of unit.
NEVER block the air openings, grills/outlets or place on a soft surface such as a bed or sofa, as this could cause the unit to tip over, blocking the air intake or outtake opening.
DO NOT attempt to repair or adjust any electrical or mechanical functions on this unit. Doing so will void your warranty. The inside of the unit contains no user serviceable parts. All servicing should be performed by qualified personnel only.
WARNING: To reduce the risk of fire or electric shock, do not use this fan with any solid-state speed control device.
WARNING: Skin or eye damage may result from directly viewing the light produced by the lamp in this apparatus. Always disconnect power before replacing lamp or servicing. Replace Lamp With Lamp Manufactured by Guardian Technologies.
