SAFETY INSTRUCTIONS
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, electric shock, and 
injury to people or property, including the 
following:
 1.   The appliance should always be placed 
on a firm, flat, waterproof surface at least 
four feet (1.2 m) away from bedside, 12 
inches (30 cm) from the wall and out of 
reach of patients, children and pets. Be 
sure the appliance 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.  
2.   The appliance should not be left  
unattended in a closed room since air 
could become saturated and leave  
condensation in front of unit, on walls  
and furniture. Leave room door partly 
open.   Do not aim mist nozzle directly 
at children, walls or furniture.
3.   Before using the appliance, extend the 
cord and inspect for any signs of damage. 
Do not use the unit if the cord has been 
damaged. Do not operate with power cord 
coiled or twist tie in place.
4.   The appliance 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.
5.   
 
CAUTION: To avoid fire or shock  
hazard, plug the appliance directly into a 
120V AC electrical outlet. To avoid risk of 
fire, shock or personal injury do not use 
an extension cord.
6.   The appliance should always be 
unplugged and emptied when not in  
operation or while being cleaned. Shut off 
and unplug humidifier before moving. Do 
not move or tilt humidifier while it is in 
operation. Plug and unplug unit with dry 
hands. Never pull by cord.
   7.   Do not operate the appliance without 
water. Turn off and unplug unit when  
tank is empty.
8.   Appliance requires regular cleaning. Refer 
to, and follow, cleaning instructions.
   9.   Do not operate outdoors; this appliance is 
intended for indoor residential use only.
 10.  Do not cover or insert objects into any  
openings on the unit.
 11.  Do not attempt to repair or adjust any  
electrical or mechanical functions on  
this appliance. Doing so will void  
your warranty.
