Chemex 821 000 User Manual

READ BEFORE USING YOUR HUMIDIFIER 
 

1)  This appliance has a polarized plug (one blade is wider than the other).  To reduce the risk of electric shock, this plug is intended to 

fit into a polarized 120-volt AC, 15 amp outlet, and only one way.  If the plug does not fit fully in the outlet, reverse the plug.  If it still 
does not fit, contact a qualified electrician.  Do not attempt to defeat this safety feature.  If an extension cord must be used, it should 
also accept the wide blade plug and meet this electrical rating. 

2)  Do not place the cord under rugs, near loose drapes, in traffic areas, nor near heat sources or combustible materials. 
3)  Do not use the humidifier if the cord is damaged. 
4)  Always unplug the power cord before filling, cleaning, servicing, or when the unit is not in use. 
5)  This humidifier is UL listed with Essick Air brand evaporative wicks in place.  To maintain your UL rating, see your service center for 

all repairs.   

6)  Regular cleaning is recommended. Refer to the CARE & MAINTENANCE section in the manual. 
 
INTRODUCTION 
 

Your Essick Air evaporative humidifier adds invisible moisture to your home by moving dry inlet air through a saturated wick.  As air 

moves through the wick, the water evaporates into the air, leaving behind any white dust, minerals, or dissolved and suspended solids.  
Because the water is evaporated, there is just clean and invisible moist air. 
 

As the evaporative wick traps accumulated minerals from the water, its ability to absorb and evaporate water decreases.  We 

recommend changing the wick at the beginning of every season.  In hard water areas, more frequent replacement may be necessary to 
maintain your humidifier’s efficiency. 
 

Use only Essick Air brand replacement wicks and chemicals.  To order parts, wicks and chemicals call 1-800-547-3888.  The 800 

Series humidifiers use Essick Air wick # 1043.  Only the Essick Air evaporative wick guarantees the certified output of your humidifier. 
Use of wicks other than Essick Air brand will void your warranty as well as the certification of output and may reduce the output of your 
humidifier. 
 
Dry air is drawn into the humidifier through the back and moisturized as it passes through the evaporative wick.  It is then fanned out into 
the room.
