REFILLING THE TANK 

When the tank is empty and the water reaches a minimum level in the tray, the unit 
will automatically shut down and stop producing moisture. The blue in-use indicator 
will turn to red color alerting that the tank is empty. Turn the humidifier off by rotating 
the Power/Mist Control Dial counter-clockwise to the OFF position and unplug the 
power cord. Remove 

water tank spring float cap, r

efill the tank with cool water, for 

best results, use distilled or filtered water. 

Do not use hot water or chemical 

additives

. Properly replace the tank on to the humidifier body. With dry hands, plug 

unit into an outlet and turn the humidifier ON. Comfortable, soothing, visible cool mist 
will be produced immediately. 

 
CLEANING THE HUMIDIFIER 

It is strongly recommended you clean your humidifier at least once a week or more 
often if you: 

 

Have hard water. 

 

Notice a buildup of impurities on or in the tray, etc. 

 

Notice an unpleasant odor. 

Always turn off and unplug the humidifier before cleaning. 
Periodically wipe the outside of the humidifier with a damp or wet soft cloth. Do not 
use harsh, abrasive cleaners on this humidifier. Never submerse the housing in liquid 
or pour liquid in or on the housing. Doing so may damage the humidifier and cause 
injuries. 

 
CLEANING THE TANK 

Put 1/2 teaspoon of chlorine bleach and 1/2 gallon of water in the tank. Let solution 
set for about 20 minutes swishing every few minutes. Empty the tank and rinse well 
with water until the bleach odor is gone. Be careful not to splash the solution on 
surfaces/clothing that may get damaged by the cleaning solution. Do not operate the 
humidifier with the chlorine bleach solution in the tank. 

 
CLEANING THE TRAY 

From time to time mineral deposits will accumulate in and on the water basin tray. 
When this occurs, the water basin tray should be cleaned.  
 

END OF SEASON CARE AND STORAGE 

Empty the tank and tray of water. Clean all surfaces with a damp, soft cloth. Allow the 
tank to dry completely without the spring float cap on. When entire humidifier is 
completely dry, store the humidifier in its original carton, in a cool, dry, clean location. 
Remember to clean and inspect your humidifier before using it the next season.
