When using electrical appliances, basic precautions
should always be followed to reduce the risk of fire,
electric shock, and injury to persons, including the fol­lowing:

1. Always place this humidifier on a firm, flat and level surface. This humidifier may not
work properly on an uneven surface.

2. CAUTION: To reduce the risk of burns, 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 the manufacturer
under the warranty agreement for repair.

5. This appliance has a polarized plug (one blade is wider than the other). To reduce the
risk of shock, this plug is intended to fit only one way in a polarized outlet. 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.

6. To disconnect the humidifier, first turn controls to the OFF position, then grip the plug and
pull it from the wall outlet. Never pull by the cord.

7. A loose fit between the AC outlet (receptacle) and plug may cause overheating and a
distortion of the plug. Contact a qualified electrician to replace loose or worn outlet.

8. The humidifier should always be unplugged and emptied when not in operation or while
being serviced or cleaned.

9. Never tilt or attempt to move the humidifier while it is operating or filled with water.
UNPLUG the humidifier before moving.

10. 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.

11. When a humidifier is used in a closed room or small rooms, check periodically for prop­er ventilation, as excessive humidity can cause condensation stains on walls.

12. Do not direct moisture flow directly at individuals, walls or furniture.

13. Turn the humidifier OFF if you notice moisture on the inside of your windows. For proper
humidity reading use a hygrometer, which is available in many hardware and depart­ment stores.

14. DO NOT touch the steam vapor. Steam can cause burns.

15. DO NOT BLOCK THE MIST GRILLE. THIS WILL DAMAGE THE HUMIDIFIER.

HOW DOES IT WORK?

Water passes into the Power Unit where it is heated and purified. The Warm Moisture
system then pulls the air through the top vent and spreads

invisible

moisture-balanced air

into the room.

SETUP

• Remove the water tank by grasping the handle and pulling

straight up. Set aside (Fig. 1).

• Turn the Water Tank upside down so that the Fill Cap is fac-

ing up; unscrew the Fill Cap by turning it counter-clockwise

and set aside.

•

Fill the Water Tank with COOL tap water (Fig. 2). Distilled
water is not necessary as the water is purified by the heating
element.

DO NOT USE HOT WATER. Doing so may damage

the humidifier.

• Replace the fill cap by turning it clockwise .

DO NOT OVER TIGHTEN.

NOTE: WHEN CARRYING THE FILLED WATER TANK,
PLEASE USE THE HANDLE AND PLACE YOUR OTHER
HAND UNDER THE TANK FOR ADDITIONAL SUP­PORT.

•

Turn the Water Tank right side up. Position the tank into the
humidifier and push it into place (Fig. 3).

• Some water will flow into the Removable Tray when the filled

tank is properly in place.

• Once the filled tank has been positioned, do not attempt to

move the humidifier. If it has to be moved, unplug the humidifi­er and remove the water tank first.

CAUTION: DO NOT POUR WATER INTO THE GRILLE
ON TOP OF THE HUMIDIFIER (Fig. 3). DOING SO
MAY DAMAGE THE HUMIDIFIER OR CAUSE PER­SONAL INJURY.

NOTE: We recommend that the humidifier be disinfected prior to first
use. Please see WEEKLY CLEANING instructions.

• Select a firm, level, flat location - at least six inches (15 cm) from any wall for proper

air flow (Fig. 1). Place the humidifier on a water-resistant surface, as water can dam­age furniture and some flooring.

Kaz will not accept responsibility for property damage caused by water spillage.

NOTE: THE USE OF OTHER WATER
TREATMENT PRODUCTS, CHEMICALS,
SOAPS, DETERGENTS OR ABRASIVE
CLEANSERS NOT RECOMMENDED IN
THE MANUAL MAY CAUSE DAMAGE
TO THE HUMIDIFIER OR AFFECT PER­FORMANCE.

We recommend cleaning the humidifier weekly, more often if you have hard water or
notice a build-up of impurities or detect unpleasant odors.

Cleaning involves two steps SCALE REMOVAL and DISINFECTING. Be sure to perform
these in the proper order to avoid harmful chemical interactions.

• First, turn off and unplug the humidifier. Wait at
least 10 minutes for the unit to cool.

• Remove the Water Tank.

• To remove the Power Unit, pull the Latch to
release (found under the Water Tank) and lift the
Power Unit (Fig. 6). Turn upside-down to check
condition of heating element. If build-up of min­erals is heavy, follow the CLEANING THE HEAT­ING ELEMENT instructions. Set the Power Unit
aside.

• Empty any water from the Base and Removable Tray.

Note: If tank appears to be damaged in any way discontinue use to
avoid water overflow.

If the unit stops producing mist, even while there is water in the tank, the mineral build­up may need to be removed from the heating element of the Power Unit.

How often you perform this special maintenance depends upon the hardness of the
water you are using and how quickly mineral deposits form on the interior surfaces of
the humidifier.

DO NOT clean the heating element under running water. Doing so may cause damage
or personal injury.

1. Unplug the humidifier. Allow at least 10 minutes for the unit to cool.

2. The heating element is on the bottom of the Power Unit. To

access it, remove the Power Unit by pulling on the Latch
(found under the Water Tank) and lifting the Power Unit
(Fig. 6).

3. Turn it upside down. BE SURE IT HAS COOLED SUFFI-

CIENTLY.

4. Use a non-metallic brush or a soft, dry cloth to wipe the

outer surfaces of the heating element (Fig. 7). Some deposit
may remain, but should not interfere with the operation of the unit.

END-OF-THE-SEASON CARE AND STORAGE

• Follow WEEKLY CLEANING instructions when the humidifier will not be used for at
least one week or more, or at the end of the season.

• Dry the humidifier completely before storing. DO NOT store with water inside the
Removable Tray, Base, or Water Tank.

• Pack the unit in its original carton and store in a cool, dry location.

• Before next use, remember to clean the humidifier.
