Operation

1. Lift the water tank (p. 3, fig. A 9 ) off of base, holding the bottom of the tank with both hands.
2. NOTE: DO NOT hold the water tank by the handle when empty or full.
3. Turn the tank upside down and unscrew the water tank cap (p. 3, fig. A 10 ) by turning it counterclockwise.
4. Fill the water tank with cold water. Do not fill all the way to the rim.
5. NOTE: If you have hard water, it is recommended to use filtered or distilled water. While using the humidifier, if you see a film of white dust, it is because of hard water.
6. DO NOT add any medication or other additives into the water tank itself. For use of essential oils, see page 17.
7. Screw the water tank cap (p. 4, fig. E 10 ) back onto the tank by turning clockwise.
8. Place the tank onto the base (p. 4, fig. F 2 ). Make sure it is lying flush into the base. There should not be a space between the tank and base.
9. Place the mist lid on top of the water tank.
10. NOTE: DO NOT move the humidifier while the water tank is on base. Water may leak into the base, causing a malfunction.
11. Plug the power cord into an electrical outlet. DO NOT use an extension cord.
12. Turn the power on by turning the control knob (p. 3, fig. A 6 ) clockwise (to the right). You will hear a minor clicking noise when turning the unit on and off. The green power indicator light (p. 3, fig. A 7 ) will turn on.
13. In a few moments, the mist will start coming through the mist channel (p. 4, fig. B 11 ) . Use the control knob (p. 3, fig. A 6 ) to adjust the intensity of the mist output. Turning the knob clockwise will increase the moisture output, turning the knob counterclockwise will reduce the moisture output.
14. Note: When at maximum level, it is normal to hear a faint dripping sound.
15. When the humidifier runs out of water, the indicator light (p. 3, fig. A 7 ) will turn red, and the mist output will stop. This is a safety feature to prevent the humidifier from possibly overheating and damaging the mist chamber (p. 4, fig. D 1 ).
16. Turn the control knob to reset and refill the water tank. In a few moments, the green indicator light will turn on. Turn the control knob to “0” position for 2 minutes and then turn power on by turning the control knob clockwise (to the right).

Setting the correct humidity output

Adjust the mist control so that the mist rises up and gets absorbed by the room air. Do not turn on too high an output as the mist cannot be absorbed by the air and accumulates on the surface around the humidifier. If the humidifier is placed near a fan or air conditioning outlet, the mist may be forced down by the foreign air stream. Change the location of the humidifier or reduce the output of the other room conditioning appliances.

Using essential oils

Essential oils can be used on the aroma pad located in the aroma tray on the top of the mist channel (p. 4, fig. B 11 ). You can mix and match any oil scents you would like.

1. Place about 3 drops of desired scent on the aroma pad located in the aroma tray (p. 4, fig. C 12 ).
2. Push the aroma pad into the medicine cup, (p. 4, fig. B 8 ) .
3. Each pad should only be used per desired scent.
4. Before attempting to reuse aroma pad with a different scent, clean the aroma pad by lightly hand washing it in warm water and letting it thoroughly air dry.

Helpful hints

1. It is best to keep the humidity level at about 30-50 percent of relative humidity.
2. The comfort level of humidity will vary from room to room and with changing room conditions.
3. In cold weather, windows and even some walls may fog or develop frost from excessive indoor humidity. If this occurs, reduce the mist intensity setting to avoid damage from condensed water dripping on windowsills.
4. 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 and walls, especially wallpaper.
5. To eliminate excessive humidity, especially in small rooms, leave the room door open and adjust the mist intensity control setting.
6. Note: To avoid possible white dust due to hard water, it is recommended to use filtered or distilled water.
7. DO NOT use hot water. Use cool tap water.
8. DO NOT add any medication or other additives to the water.
9. DO NOT pour water into Vapor Outlet Channel (p. 4, fig. B 11 ).
10. Note: Do not attempt to move humidifier while water tank is placed on the water basin. Doing so may cause leakage of water. Also, do not place humidifier on the floor. Place humidifier on an elevated surface.

Troubleshooting

CAUTION! DO NOT attempt to repair the motor or nebulizer yourself. If the humidifier continues to not operate, please call customer service.

Cleaning and maintenance

Portable humidifiers require regular cleaning in order to reduce the risk of bacterial growth and also to remove any scale residue to maintain good operational performance. Follow the procedures below for healthy maintenance of your warm-mist humidifier.

CAUTION! NEVER PLUG OR UNPLUG A HUMIDIFIER WITH WET HANDS.

Always be sure that the humidifier is unplugged and switched OFF before cleaning or attempting to clean or store the item. DO NOT leave water in water tank (p. 3, fig. A 9 ) or water basin when the unit is not in use, as it may result in the buildup of mineral deposits and bacteria that can inhibit the output efficiency of the humidifier. PLEASE NOTE that if water remains in the water tank for more than a day or two, bacterial growth is possible.

NOTE: When removing the water tank, water may accumulate under the vapor lid and on the bottom of the water tank. It is recommended to have a dry cloth ready to dry wet surfaces.

Disinfecting the water tank and water basin

4. Let it stand for twenty minutes, shaking vigorously with two hands every few minutes.
5. Carefully empty the tank after 20 minutes, and rinse with warm water until you can no longer detect a vinegar smell.
   NOTE: It is recommended to clean the humidifier with water and a white vinegar solution as stated above after using the humidifier about once a week or if cleaning seems necessary.
   IMPORTANT: Failure to keep this humidifier clean from mineral deposits normally contained in any water supply will affect the efficiency of the operation. Customer failure to follow these instructions may void the warranty.

How to clean the heating element in the base

1. To remove the mist chamber, slide the mist chamber latch to the left and carefully lift the mist chamber off the water basin.
2. Fill the heating element with undiluted white vinegar.
3. Let it stand for 20 minutes. Dampen a soft, clean cloth or sponge with undiluted white vinegar and wipe out the heating element to remove scale. DO NOT use soap, detergents or abrasive cleaners.
4. Rinse the heating element using clean, warm water, being careful not to submerge the base in the water. Dry thoroughly. DO NOT IMMERSE THE WATER BASIN IN WATER.

6. To attach the mist chamber, slide the mist chamber latch to the left and place the mist chamber onto the water basin. Release the latch to secure the mist chamber
   to the water basin.

How to clean humidifier exteriors
