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

PRODUCT CONTAIN CHEMICALS, INCLUDING LEAD OR LEAD COMPOUNDS,
KNOWN TO THE STATE OF CALIFORNIA TO CAUSE CANCER AND BIRTH

(CALIFORNIA CODE OF REGULATIONS PROPOSITION 65)

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 portable air purifier has a polarized plug (one blade is wider than the other) as

a feature to reduce the risk of electric shock. This plug will fit into 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. Never use an extension cord unless the plug can be fully inserted. Do not alter the plug.

• 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.

WARNINGS

Failure to comply with the warnings listed below may

result in electric shock or serious injury.

•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.

•DO NOT place anything on top of unit.

•WARNING: To reduce the risk of fire or electric shock, do not use this fan with any solid-state

speed control device.
