WARNING
When using electrical appliances, basic precautions should always be followed to
reduce the risk of fire, electric shock, and injury to person, including the following:
• Use appliance only as described in this manual. Any other use not recommended
by the manufacturer may cause fire, electric shock, or injury to persons. The use
of attachments not recommended or sold by the manufacturer may cause hazards.
DO NOT use outdoors.
• To avoid fire or shock hazard, plug the appliance directly into a 120V AC electrical
outlet. DO NOT plug in the cord with wet hands.
• Keep the cord out of heavy traffic areas. To avoid fire hazard, NEVER put the cord
under rugs or near heat registers.
• DO NOT operate any appliance with a damaged cord or plug, if the appliance
malfunctions, or if it has been dropped or damaged in any manner. Return appliance
to manufacturer for examination, electrical or mechanical adjustment, or repair.
• 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.
• Humidifier should be unplugged when not in use.
• DO NOT place humidifier near heat sources such as stoves, radiators, and heaters.
DO locate your humidifier on an inside wall near an electrical outlet. The humidifier should
be at least 12 inches (30.5 cm) away from the wall for best results. DO NOT allow the mist
outlets to directly face the wall. Moisture could cause damage, particularly to wallpaper.
• NEVER place humidifier in an area where it is accessible to children. NEVER use
humidifier in a closed room, particularly where a child may be sleeping, resting,
or playing (a closed room may result in excessive humidity).
CAUTION
• This product is not a toy. DO NOT allow children to play with it.
