How Your Humidifier Works
Your new MoistAIR® Evaporative
humidifier is designed to satisfy home
humidity requirements through the
principle of evaporation of water in the
air.
Once the wick becomes saturated, air
is drawn in, passes through the wick
and moisture is absorbed into the air.
All evaporation occurs in the
humidifier so any residue remains in
the wick. This natural process of
evaporation creates no white dust like
some other humidifiers.

IMPORTANT: Water damage may
result if condensation starts to form
on windows or walls. Humidity SET
point should be lowered until
condensation no longer forms. We
recommend room humidity levels do
not exceed 50%.
Set Up and Location
1) Unpack humidifier from carton and remove all packaging material, wick, etc. from box.
REMOVE THE PLASTIC WRAP AROUND WICK
2) Place humidifier on a flat level surface. Position the humidifier where the most
humidity is needed or where the most air will be circulated throughout the house such
as near a cold air return. If the unit is positioned close to a window, condensation may
form on the window pane. If this occurs the unit should be repositioned in another
location.
WARNING:
For your own safety, do not use humidifier if any parts are damaged or missing.
NOTE: Due to release of cool, moist air from humidifier, it is best to direct air away
from thermostat and hot air registers, and to position humidifier next to an inside wall.
Unit should not be placed where cold air from outside walls or warm air from a hot air
register blows directly on it. If humidifier is not placed on a level surface, leakage may
occur.
3) Place the humidifier at least 4 inches from the wall.
.
CAUTION: Do NOT position the unit directly in front of a hot air duct or radiator.
Do NOT place on soft carpet. We suggest placing the unit on a table or on a
bookshelf.

Filling
CAUTION: Disconnect power before filling, cleaning or servicing unit.
Keep grille dry at all times.
1) Remove water bottle and unsc r ew cap on bottom. Fill bottle with unsoftened water.
Replace cap and tighten securely. Use both hands to carry the bottle to the base.
NOTE: If only softened water is available, it can be
used; however you will notice a build up of minerals
on the evaporative wick much sooner.
2) While the bottle is removed from the unit, make
sure wick is resting all the way into the water
channel.
3) Return bottle to its upright position using the
handle on the top of the bottle. Set the bottle
in the recessed area with the top of the bottle
flush with the top of the humidifier. When
positioned properly, the valve will open and
water will flow into the water channel.
Wick Placement
CAUTION: Do not spill water on fan motor. Electrical components must be kept
.

4) We recommend using only EPA registered bacteriostat treatment such as Essick Air
Bacteriostat, Part Number 1970 whenever you refill the humidifier to eliminate
bacterial growth. Add bacteriostat according to the instructions on the bottle.
5) Plug cord into wall receptacle.
Controls & Operation
The humidifier should be placed at least FOUR inches away from any walls and away
from heat registers. Do not place on soft carpet. Unrestricted airflow into the unit will
result in the best efficiency and performance.

Fan ON/OFF and
Fan Speed Button
1) For initial operation, plug the unit in (the display will show 00). Press the speed
button once. The fan speeds cycle from high to low. The unit will initialize and begin
reading the room humidity.
2) The built-in hygrometer reads the current room humidity and displays the percentage
on the right bar graph.
3) To set the desired humidity, press the HUMIDITY button and observe the left bar
graph climb with each pressing. Each successive push increases the humidity in 10%
increments. Once it reaches the maximum, it cycles back to the beginning.
4) Press the SPEED button to adjust the fan setting. Use low setting (01) for the quietest
operation and the high (04) for maximum output.
5) TO STOP the unit, press the SPEED button for two seconds
NOTE: If excessive condensation occurs, reduce fan to a lower speed setting.
Auto Humidistat
Once the unit is on, the automatic humidistat function allows you to set the desired
humidity level and the fan speed (01 through 04), and the unit will operate until the desired
humidity level is reached. When reached, the fan will turn off.
When the humidity level drops below the set humidity, the fan will turn on automatically.
Care and Maintenance
Cleaning your humidifier regularly helps eliminate o dors, bacterial and fungal growth.
Ordinary household bleach is a good disinfectant and can be used to wipe out the
humidifier base and bottle after cleaning.
We recommend cleaning your humidifier at least once a week to maintain optimum
environmental conditions from your humidifier.
We also recommend using Essick Air Bacteriostat Treatment each time you refill
your humidifier to eliminate bacterial growth. Add bacteriostat according to the
instructions on the bottle. Please call 1-800-547-3888 to order Bacteriostat Treatment
reference part number 1970.
Cleaning Instructions
1) Turn off unit and unplug from outlet.
2) Remove water bottle from the
humidifier and place it in a secure
place. Locate the two internal spring
latches on the front and rear of the
base. Releasing these latches will
allow removal of the top housing.
Flex the rear latch and lift the back of
the top housing off the base far
enough to clear the latch. Flex the
front latch and lift the complete top
housing away from
the base. Place the top housing
on a flat surface. See illustration.
Removing Scale
3) Once separated from the chassis, place the base of the unit in the top rack of a
dishwasher, or hand wash by filling with water and adding 8 oz. of white vinegar. Let
solution set for 20 minutes, then empty and rinse thoroughly.
4) Similarly, clean the bottle by filling with water and 8 oz. of white vinegar, then allow to
set for 20 minutes. Rinse thoroughly.
5) Lift the wick from the unit and let excess water drain. Rinse wick under fresh water
only. Do not use soap, detergent, or any other cleaners on the wick. Leave in sink to
drain.
