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, 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, in traffic areas, or near heat sources.

3) Do not use the humidifier if the cord is damaged.

4) Always unplug the power cord before cleaning, servicing, or
when the unit is not in use.

5) Do not place the humidifier near loose drapes, combustible materials, or
heat-producing objects.

6) This humidifier is UL approved with Bemis by Essick Air brand evaporative
wicks in place. To maintain your UL rating, see your service center for all
repairs. Use only Bemis by Essick Air brand replacement wicks and chemi­cals. To order parts, wicks, and chemicals call 1-800-547-3888.

7) Regular cleaning is recommended. Refer to the CARE & MAINTENANCE
section in this manual.

8) It is very important that cleaning solutions and other liquids, such as
bleach, which may be used to clean the cabinet are not sprayed or
applied to the power pak/chassis assembly. These cleaning solu­tions can cause a serious electrical malfunction of the humidifier.

Introduction

Your Bemis by Essick Air evaporative humidifier adds invisible moistur
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, and no white dust, just clean and invisible
moist air.

As the wick traps accumulated minerals from the water, its ability to absorb
and evaporate water decreases. We recommend changing the wick at least
once a year, preferably disposing of the used wick at the end of the humidify­ing season and starting with a new one at the beginning of the next humidify­ing season. In hard water areas, more frequent replacement may be necessary
to maintain your humidifier's efficiency.

e to your

NOTICE: We recommend using Bemis by Essick Air Bacteria Treatment,

whenever you refill the water bottles to eliminate bacteria growth. Follow
the directions to determine the proper amount to be added to the 2.75 gallon
water bottles.

The evaporative wick does not require the use of chelating agent type water treat­ments that are intended for use in Rotobelt or Water Wheel type humidifiers.

Your humidifier is equipped with two water bottles. When both bottles have
emptied, the humidifier fan will automatically shut off and the "Refill Water
Bottles" message will light. The unit will start again automatically when the
water bottles are refilled. The right bottle will empty first. If it does not do so,
the humidifier may not be level.

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.

Locate your humidifier on an inside wall, near an electrical outlet. The humidifi­er should be at least 4" away from the wall for best results. Do not position the
unit directly in front of a hot air duct or radiator.

Assembly and Operation

1) Unpack humidifier from carton.

2) Remove all packaging materials. Check to see that you have all of the fol­lowing items before discarding packaging:

Fill hose Cord Set
Evaporative wick Two end covers
Two water bottles with caps Caster kit
Air Care filter if unit is an Air Care model

NOTICE: The wick and Air Care filter are packaged to prevent breakage

in shipping. They must be removed from the unit and correctly installed
according to these instructions prior to operation to prevent damage to
the unit.

CASTERS

3) Remove the water bottles, chassis and evaporative wick from the base of
the humidifier. Turn the base of the empty humidifier upside down. Insert
the caster stem into the large caster holes in the four corners of the humidifi­er bottom. The casters should fit snugly and be inserted as far as possible.
Do not force. When all four casters are in place, turn the unit right side up.

EVAPORATIVE WICK

4) The wick has a mounting rib on
the top edge which hooks over a rib
at the inside back of the cabinet. This
allows the wick to hang in the water
channel (see illustration). Hang evapo­rative wick into cabinet as shown.

AIR CLEANING FILTER (Models

4D7 800, 497 800, 497 300,
447 401, 447 301 & 427 300)

5) The Air Care filter has four tangs that
engage into four keyhole slots that
mount the Air Care filter onto the out­side of the back of the cabinet.

CHASSIS/POWER PAK

6) Place the chassis/power pak unit into the cabinet ensuring that
chassis/power pak seats correctly onto the front and back edges of the
cabinet.

BOTTLES

7) Fill the bottles with cool, fresh, preferably unsoftened water. If you
have only softened water available in your home, you may use it, but you
will notice a buildup of minerals on the wick much sooner. The bottles hold

2.75 gallons each. When filling the bottles, be careful not to pressurize
them by over filling. Bottle damage can result from this. To reduce carrying
weight, the bottle may be partially filled and unit will still operate properly.
A fill hose is provided with your humidifier which will fit most faucets.

8) We recommend using Bemis by Essick Air
Bacteria treatment whenever you refill the
water bottles to eliminate bacterial growth.

Add bacteriostat according to the instructions on the bot­tle and then tighten the valve caps on your water bottles.

9) Place water bottles into the humidifier with the valve cap
end down and to the back of the humidifier so that the
valve cap enters the water channel, aligning with the
“post” in the cabinet.

10) Place the end covers over the water bottles.

11) Plug cordset into interlock receptacle on back of unit.

12) Plug cordset into wall receptacle. Humidifier is now ready
for use.

CONTROLS (Models 497 800, 497 300, 496 800,

447 401, 447 301, 427 300)

FAN SPEED

13) Open control panel door by lifting with your finger under
the finger tab. Depending on which model you have, you
will have a choice of two, three, four or variable fan
speeds allowing you to use a low setting for the most
quiet operation or a high setting for maximum output.

HUMIDITY SETTING

14) All models have an automatic humidistat. The humidistat
will turn the humidifier on when the relative humidity in
your home is below the humidistat setting and will turn
the humidifier off when the relative humidity reaches the
humidistat setting. For initial operation set the humidistat
in the "comfort zone" and adjust up or down from there
to achieve the desired humidity level. Turning the varia­blespeed humidistat all the way counterclockwise will
turn the unit off regardless of the relative humidity. This
must be turned on again before the unit will work.

REFILL LIGHTS

15) The “Refill Bottles” indicator will light, and the motor
will turn off when the bottles are empty. The right bottle
will empty first, then the left bottle. If the “Refill Light”
comes on, and the right bottle has not emptied, raise
the right side of the unit until it is level.
