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 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 Series humidifiers use Essick Air wick # 1041
and accommodate optional 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.
