READ AND SAVE THESE SAFETY 
INSTRUCTIONS BEFORE USING  
THIS HUMIDIFIER
When using electrical appliances, basic 
precautions should always be followed to 
reduce the risk of fire, electrical shock and 
injury to persons, including the following:
1.  The humidifier should always be placed on a 
firm, flat, waterproof surface at least four feet 
(1.2 m) away from bedside, twelve inches  
(30 cm) from the wall, and out of reach of 
patients, children and pets.
2.   Be sure the humidifier is in a stable position 
and the power cord is away from heated 
surfaces and out of the way to prevent the 
humidifier from being tipped over.
3.   Before using the humidifier extend the cord 
and inspect for any signs of damage. Do not 
use the unit if the cord has been damaged.
4.   The humidifier has a polarized plug (one blade 
is wider than the other) as a safety feature.  
This plug will fit into a polarized outlet only 
one way. If the plug does not fit fully into the 
outlet, reverse the plug. If it still does not fit, 
contact a qualified electrician. Do not attempt 
to defeat this safety feature.
