This appliance is equipped with a polarized plug. This type of plug has one
blade wider than the other. The plug will fit into an electrical outlet only one way.
This is a safety feature intended to help reduce the risk of electrical shock.
If you are unable to insert the plug into the outlet, try reversing the plug. If the
plug should still fail to fit, contact a qualified electrician to replace the obsolete
outlet. Do not attempt to defeat the safety purpose of the polarized plug by
modifying the plug in any way.
If a longer cord is necessary an approved extension cord may be used. The
electrical rating of the extension cord must be equal to or greater than the
rating of the humidifier. Care must be taken to arrange the extension cord so
that it will not drape over the countertop or tabletop where it can be pulled on
by children or accidentally tripped over.
Choose a flat, level, water-resistant location for the humidifier that will allow for
good air circulation and that is not accessible to children.
Do not place the humidifier where it or its cord presents a tripping or stumbling
hazard, or where the air vents are blocked.
