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.
• A short power supply cord should be used to reduce the risk resulting from becoming entangled in or
tripping over longer cord.
• Extension cords may be used if care is exercised in their use and if they are of proper voltage and plug
• If extension cord is used:
1. The marked electrical rating of the cord set or extension cord should be at least as great as the
electrical rating of the appliance; and
2. The cord should be arranged so that it will not drape over the countertop or tabletop where it can be
pulled on by children or tripped over unintentionally.
If the electrical circuit is overloaded with other appliances, your appliance may not operate properly. It should be
operated on a separate electrical circuit from other appliances.
120V AC Power Supply Only
Place the humidifier on an elevated, non-metallic, lint-free, water-resistant, level surface at least 5 inches away
from walls, heat sources, and ledges.
DO NOT place on carpet, towel or fabrics. The fan vent is located on the bottom of the water basin. The fan vent
MUST NOT be obstructed.
DO NOT place the humidifier on a wooden surface or near furniture and electronics (laptop, cell phone, tablets,
etc) than can be damaged by moisture.
The fan vent is located on the bottom of the humidifier. The purpose of the fan vent is to blow the cool mist
through the mist outlet. It is important that this part be kept clean and free of any obstructions. We recommend
checking the fan vent before using this item (i.e. free of lint, paper, etc.).
Do not place the humidifier on top of a towel or carpeted surface. The fan vent on the bottom may
become blocked and overheat the humidifier.
CAUTION: DO NOT operate the humidifier without water in the water tank
DO NOT plug or unplug the power cord with wet hands as electric shock may occur.
It is best to keep the humidity level between 30~50 percent of relative humidity.
The comfort level of humidity will vary from room to room and with changing room conditions.
In cold weather, windows and sometimes walls may fog or develop frost from excessive indoor humidity. If
this occurs, reduce the mist intensity setting to avoid damage from condensed water drippings.
Too much humidity in the room may allow moisture to accumulate on surfaces where bacteria and fungi can
grow. Moisture that gathers may also damage furniture, walls and wallpaper.
To eliminate excessive humidity, especially in smaller rooms, leave the room door or window open and
adjust the mist intensity control accordingly.
NOTE: this is an ULTRASONIC COOL MIST humidifier. The mist is cool. There is no steaming or boiling of
1. Place unit on a smooth level surface that can support the unit when filled with water.
2. Make sure the unit is unplugged and in the off position.
3. Remove the adjustable misting outlet.
4. Lift the water tank and turn upside down.
5. Unscrew cap from water tank by turning the cap counterclockwise.
6. Fill with COOL tap water or DISTILLED water up to the max fill line. Do not overfill.
DO NOT use hot water
DO NOT add fragrance or oil in the water – it will cause malfunction of the unit!
DO NOT pour water into the misting outlet.
When carrying a filled water tank, place one hand under for support.
7. Screw the cap back on by turning cap clockwise. Do not over tighten.
8. Turn the water tank right-side up and carefully place the water tank onto the base, be sure tank is correctly
aligned with base and there is no gap between the tank and base.
NOTE: DO NOT attempt to move the humidifier while water tank is in place. Doing so may cause leakage of
water. Also, do not place humidifier on the floor. Place humidifier on an elevated, lint-free, waterproof, level
surface for best performance.
9. Place the adjustable misting outlet back in place, on top of the water tank. Plug the power cord into a 120V
wall socket.
10. Turn the mist dial clockwise to turn on unit. The indicator light will illuminate.
GREEN: There is enough water in the base and unit is in operation.
RED: Water tank is empty and needs to be refilled.
NOTE: It may take 15 to 30 seconds for the green indicator light to come on. As the water fills the basin,
that is the amount of time needed for the water sensor to sense the water level.
11. Turn the dial to adjust mist intensity, turn the dial clockwise to increase and counter-clockwise to decrease.
NOTE: When set at the max intensity, it is normal to hear a faint humming sound.
12. When the humidifier runs out of water, the indicator light will turn red and the mist output will stop. This is a
safety feature to prevent the humidifier from possibly overheating. Turn the mist dial counterclockwise to
“OFF”, unplug unit and refill water tank.
If the Red indicator light illuminates after powering on, either the unit is out of water or tank is not
properly aligned.
Once the water tank is in place, do not attempt to move the humidifier. If it has to be moved, unplug the
unit and drain water from the base before moving.
WARNING: When selecting the correct humidity output, make sure that the mist intensity is not set too high,
because the mist may not be fully absorbed by the air and may accumulate on surfaces around the
humidifier. If the humidifier is placed near a fan or air conditioning outlet, the mist may be forced in a
different direction, due to air pressure. Change the location of the humidifier or reduce the output of other
room conditioning appliances.
1. Always make sure the unit is unplugged and in the OFF position.
2. Carefully lift the water tank up and hold in upright position (over the base) for about 15 seconds to allow
excess water to drip into the water basin.
3. Turn the water tank upside down, with cap facing towards the ceiling, to refill.
WARNING: DO NOT leave water in the tank or basin when unit is not to be used as it may result in the build up
of mineral deposits and bacteria that can inhibit the output efficiency of the humidifier. If water remains in the
tank or basin for more than a day or two, bacterial growth is possible.
Turn off power and unplug unit before cleaning.
Never use a detergent or any cleaning chemicals to clean the tank or base. Detergent dissolved in the water
supply can interfere with the mist output.
If water tank or base is extremely dirty, soak with a mild bleach (or vinegar) and water solution and rinse
clean. Never use detergent.
Wipe the exterior of the body with a damp cloth.
Do not spray water or any liquid onto the control.
Never immerse the base in water or let water enter the air outlet or other openings.
Clean and rinse the water tank and mist nozzle with lukewarm water frequently to avoid mineral build up.
Keep the nebulizer (silver plate in the base) and water sensor free of mineral deposits. Remove the water
tank and empty the reservoir. Clean the nebulizer and sensor with a soft brush (old toothbrush). Do not
scrape the nebulizer or water sensor. Do not clean with tools that have metal parts.
NOTE: always empty the tank and base if not planning to use the unit for a few days.
Save the box for off-season storage.
Clean the tank, base and all parts thoroughly and dry completely before storage. Make sure the interior of
the tank is completely dried before returning capping.
If water is left in the unit during storage, it may harden and leave deposits that may affect the unit from
operating properly.
Leave the cap of the water tank loose. This will prevent the cap and gasket from sticking together and
prolong the life of the gasket.
Store the humidifier in a cool, dry place. Do not place any items on top of the humidifier as this may result in
possible damage. Keep the cord away from metal objects. Always check the plug before use .
