READ ALL INSTRUCTIONS BEFORE
USING THIS HUMIDIFIER. SAVE THE
INSTRUCTIONS FOR EASY REFERENCE.
WHEN USING ANY ELECTRICAL APPLI-
ANCE, BASIC SAFETY PRECAUTIONS
SHOULD BE FOLLOWED INCLUDING:
1. This humidifier may not work properly
on an uneven surface. Always place
this humidifier on a firm, flat and level sur-
face.
2. Place this humidifier in an area where it
is not accessible to children.
3. Do not place the humidifier near any
heat sources such as stoves, radiators and
heaters.
4. Before using the humidifier, check the
power cord for any signs of damage.
If the cord is found to be damaged, DO
NOT USE and return the humidifier to
Duracraft under the warranty agreement
for repair.
5. This product is equipped with a
polarized AC-line plug (a plug having one
blade wider than the other). This plug will
fit into the power outlet only
one way. This is a safety feature.
NEVER connect the humidifier to any
power source other than a 120V AC
polarized outlet. If you are unable to insert
the plug fully into the outlet, try reversing
the plug. If the plug should still fail to fit,
contact an electrician to replace the obso-
lete outlet. DO NOT defeat the safety pur-
pose of the polarized plug.
6. The humidifier should always be
unplugged and emptied when not in oper-
ation or while being serviced or cleaned.
7. Never tilt or attempt to move the humid-
ifier while it is operating or filled with
water. UNPLUG the humidifier before mov-
ing.
8. This humidifier requires regular
cleaning. Refer to the CLEANING
instructions provided. Never clean the
humidifier in any manner other than as
instructed in this manual.
9. Turn the humidifier OFF if the relative
humidity exceeds 60%, or if you notice
moisture on the inside of your windows.
For proper humidity readings use a
hygrometer which is available in many
hardware and department stores, or
by ordering one from Duracraft (see
Replacement Parts and Care Products).
10. Do not touch the steam vapor.
Steam can cause burns.
IMPORTANT SAFETY INSTRUCTIONS

Thank you for purchasing a DURACRAFT®
NATURAL WARM MOISTURE™
HUMIDIFIER.
This humidifier produces warm moisture. It
automatically shuts off when the tank is
empty or removed, or when the Mist
Chamber is removed.
Before using your humidifier, we would like
to explain the benefits of maintaining your
home or office at the proper
humidity level.
HEALTH
Your body needs moisture to stay healthy
and comfortable. Dry air can be damag-
ing and irritating. The Duracraft®Natural
Warm Moisture™ Humidifier can help
relieve:
• Dry, itchy skin and chapped lips.
• Cold symptoms and congestion.
• Dry, scratchy throat and coughs.
For serious medical conditions, always
consult your physician prior to use.
ENVIRONMENT
Maintaining the proper moisture level in
your home or office with your Duracraft®
Natural Warm Moisture™ Humidifier will also
help to:
• Replace needed moisture in furniture.
• Keep indoor plants moist and healthy.
• Eliminate cracking and dryness in
wood furniture and fixtures.
• Minimize static electricity.
HOW DOES IT WORK?
Water passes into the Mist Chamber where
it is heated and purified. The Natural
Warm Moisture™ System then pulls the air
through the top vent and
disperses invisible, moisture-balanced
air into the room.
INTRODUCTION

• Select a firm, level, flat
location — at least six
inches from any wall for
proper air flow and conve-
nient to an electrical outlet.
• Place the humidifier on
a water-resistant surface,
as water can damage fur-
niture and some flooring.
Duracraft will not accept
responsibility for property
damage caused by water
spillage.
• We recommend that the
humidifier be disinfected
prior to first use.
Please see CLEANING
instructions.
• Remove the No Drip™
water tank by grasping the
handle and pulling straight
up (Figure 1).
• Turn the water tank
upside-down so that the fill
cap is facing up; unscrew
the fill cap by turning it
counter-clockwise and set
aside.
• Fill the tank with COOL
tap water (Figure 2). DO
NOT USE HOT WATER.
Distilled water is not neces-
sary as the water is puri-
fied by the heating ele-
ment.
• Replace the fill cap by
turning it clockwise. DO
NOT OVER TIGHTEN.
NOTE: WHEN CARRYING
THE FILLED WATER TANK,
PLEASE USE THE HANDLES
ON THE TOP AND
BOTTOM OF THE TANK
FOR ADDITIONAL
SUPPORT.
• Turn water tank right-
side up.
• Position water tank into
the humidifier and push it
into place.
• Some water will empty
into the reservoir base
when the filled water tank
is properly positioned.
• Once the filled tank has
been positioned, do not
attempt to move the humid-
ifier. If it has to be moved,
unplug the humidifier and
remove the water tank first.
NOTE: DO NOT POUR
WATER INTO THE GRILL
ON THE TOP OF THE
HUMIDIFIER. DOING SO
MAY DAMAGE THE
HUMIDIFIER OR CAUSE
PERSONAL INJURY.

• When you are finished
using the humidifier, turn
the power switch to OFF.
• ALWAYS be sure to dis-
card any unused water in
the base each time you

• Turn the Humidity Level
knob to the HIGH position
(the darkest raindrop).
Press the RESET button
located on the front of the
unit.
This will start the humidifier
and the power light will
illuminate.
NOTE: IF THE HUMIDIFIER
WILL NOT RUN, THE
HUMIDISTAT MAY BE SET
TOO LOW. MOVING THE
HUMIDITY LEVEL KNOB
TO A HIGHER SETTING
(CLOCKWISE) SHOULD

• When a comfortable
humidity level is reached,
lower the Humidity Level
(Humidistat) setting slowly
until the heating element
shuts off. The DESIRED
HUMIDITY light will illumi-
nate, indicating that the
desired humidity setting
has been reached. The
Humidistat will automati-
cally restart the heating
element each time the
humidity level falls below
this setting. This
"ON/OFF" cycle will con-
tinue periodically while the
humidifier is in use.
NOTE: When the DESIRED
HUMIDITY light illumi-
nates, the power light will
shut off.
• If condensation forms on
walls or windows, lower
the Humidistat.
• When you are finished
using the humidifier, turn
the power switch to OFF.
• ALWAYS be sure to dis-
card any unused water in
the base each time you
refill the water tank or
finish using the humidifier.
OPERATION

REFILLING THE
HUMIDIFIER
• The humidifier will auto-
matically shut off when it is
empty. Refill when the tank
is empty or when the
REFILL light glows
(DH-911/DH-912).
• ALWAYS be sure to dis-
card any unused water in
the water tank or base
before refilling.
IMPORTANT: AFTER FILL-
ING THE TANK AND
REPOSITIONING IT INTO
THE HUMIDIFIER, THE
“RESET” SWITCH MUST BE
PRESSED ONCE THE
HUMIDIFIER HAS BEEN
TURNED TO AN “ON”
POSITION. IF THE “RESET”
SWITCH IS NOT PUSHED,
THE UNIT WILL NOT

We recommend that you
clean the humidifier once a
week, or more often if you:
• have hard water,
• notice a build-up of
impurities, or
• detect unpleasant odors.
It is normal for deposits
from tap water to collect in
the Remove and Rinse™
tray.
DO NOT USE SOAP,
DETERGENTS, OR
ABRASIVE CLEANSERS.
Cleaning involves two
steps: SCALE REMOVAL
and DISINFECTING. Be
sure to perform these in the
proper order to avoid
harmful chemical interac-
tions.
• First, turn off and
unplug the humidifier. Wait
at least ten minutes for the
humidifier to cool.
• Remove the No Drip™
water tank by grasping the
handle and pulling straight
up.
MODELS DH-909/DH-910
• Remove the Mist
Chamber by pushing the
locking tab and lifting up
from the Base (Figure 5).
Never remove the Mist
Chamber until the humi-
difier has cooled.
MODELS DH-911/DH-912
• Remove the Mist
Chamber by pulling out the
locking knob and
lifting up from the base
(Figure 6). Never remove
the Mist Chamber until the
humidifier has cooled.
• DO NOT clean the Mist
Chamber or heating ele-
ment under running water.
Doing so may cause dam-
age or personal injury.
• Use a dry, soft cloth to
wipe the outer surfaces.
Step One: WEEKLY
SCALE REMOVAL
(Remove and Rinse™ Tray)
• Lift the Remove and
Rinse™ tray out of the unit.
• Fill the Remove and
Rinse™ tray with
DuraRinse™ Humidifier
Cleaner (#AC-816), follow-
ing bottle instructions, or
one 8-oz. cup of undiluted
white vinegar. Let solution
stay for 20 minutes.
• With DuraRinse™ or
vinegar still in the tray,
clean all interior surfaces
of the tray with a soft
brush or cloth to remove
scale.

• Flush the Remove and
Rinse™ tray thoroughly
with clean, warm water to
remove scale and cleaning
solution.
NOTE: Remove and
Rinse™ tray is dishwasher-
safe. If you choose to clean
it this way, instead, you
may skip the Weekly
Disinfecting Step.
Step Two: WEEKLY
DISINFECTING
(No Drip™ Water Tank
and Remove and Rinse™
Tray)
• Be sure the water tank is
empty. Fill with 1 teaspoon
chlorine bleach in 1 gallon
water. Let solution stay 20
minutes, swishing every
few minutes to wet all sur-
faces.
• Empty tank after 20 min-
utes. Rinse with water until
bleach smell is gone.
• Repeat for the Remove
and Rinse™ tray if you
have not cleaned it in the
dishwasher.
AFTER
DISINFECTING…
• Reposition the medicine
cup, tray, power unit (lock-
ing securely), and water
tank in the base.
Special Maintenance —
Heating Element
• If the output drops, or if
the REFILL light illuminates
while there is water in the
tank (DH-911, DH-912),
scale buildup needs to be
removed from the heating
element.
• The heating element is
located on the bottom of
the Mist Chamber. To
access it, pull out the lock-
ing knob and lift the Mist
Chamber directly up off the
base. Turn it over.
BE SURE YOU TURN
OFF AND UNPLUG
THE UNIT AND ALLOW
THE HUMIDIFIER TO
COOL SUFFICIENTLY
BEFORE CLEANING THE
HEATING ELEMENT.
• Use a non-metallic brush
or a dry, soft cloth to wipe
the outer surfaces.
•DO NOT clean the heat-
ing element under running
water. Doing so may cause
damage or personal injury.
How often you perform this
special maintenance
depends upon the hardness
of your water and how
quickly mineral deposits
form on the interior surfaces
of the humidifier.
END-OF-SEASON
CARE AND STORAGE
• Follow weekly CLEAN-
ING instructions at end of
humidification season or
when humidifier will not be
used for at least one week
or more.
• Let humidifier dry com-
pletely before storing. Do
not store with water inside
the reservoir base or water
tank.
• Pack the unit in its origi-
nal carton and store in a
cool, dry location.
• Remember to clean the
humidifier at the start of
the next humidification sea-
son.
