IMPORTANT SAFEGUARDS
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 draperies, 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 ETL listed with Essick Air brand evaporative wicks in place.
6. It is very important that cleaning solutions such as bleach, anti-bacteria treatment or descaler,
which could be used to clean the cabinet, are not sprayed or applied to the chassis assembly.
These solutions can cause serious electrical malfunction of the humidifier.
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 no messy mist or spray, 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 400 and 600 Series humidifiers use Essick Air wick # 1041 and
accommodate air filter #1051. 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 efficiency of your humidifier.
CAUTION: Do NOT position the unit directly in front of a hot air duct or radiator. Do NOT
place on soft carpet.
HOW YOUR HUMIDIFIER WORKS
Dry air is drawn into the
humidifier though the
back and moisturized
as it passes through the
evaporative wick. It is
then fanned out into the
room.
