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 may 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
ASSEMBLY
UNPACKING AND SETTING UP THE UNIT
1. Remove the two inserts from the top of the humidifier.
2. Lift off the water bottle covers. Remove the water bottles, lift off the
chassis/power pack and then remove the humidifier cabinet from the carton.
3. Remove the evaporative wick and all of the remaining packaging materials
from the cabinet. Check to see that you have all of the following items
removed from the boxes, accessory kit, and cabinet before discarding the
packaging:
♦ Filler Hose
♦ Evaporative Wick
♦ Caster kit
♦ Top lid (696 & 697) (Two end covers (447)
♦ Bacterial treatment sample
♦ Optional Air Care® filter (included on 697 and
447 models; sold separately on 696 model)
♦ Two Water Bottles
CASTERS
4. Turn the emptied cabinet upside down. Insert each caster stem into a caster
hole on each corner of the humidifier bottom. The casters should fit snugly
and be inserted until the stem shoulder reaches the cabinet surface.
5. Turn the cabinet right side up.
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.
