Unique Features and Specifications

Unique Features

Ultrasonic Technology

This humidifier uses ultrasonic high frequency technology to convert the water into 1–5 million super particles that are dispersed into the air evenly.

Warm & Cool Mist Function

Choose either warm or cool mist for customized comfort.

Night Light

A useful night light feature is included for your convenience.

Auto Shut-Off Protection

When the tank is empty the unit will shut off automatically.

Specifications

Run time is calculated based on using cool water and setting the mist level between the low and medium settings. Based on the natural humidity level in your home, the temperature of water you use, and the mist level setting you choose, you may experience longer or shorter run times.

How to Use

Control Panel Description: The unit features a Power ON/OFF button, a Warm Mist button, a Night Light ON/OFF button, and a Mist Increase/Decrease Adjustment Knob. The Night Light illuminates a ring around the knob.

Power ON/OFF Button

Plug the unit into a 120-volt AC electrical outlet. Press the POWER ON/OFF button to turn the unit on. Press the POWER ON/OFF button again to turn the unit off.

ATTENTION: When the water in the tank is almost empty, the humidifying function will power off to indicate to the user to refill the tank.

Mist Adjustment Setting

Mist adjusts from lowest output to highest output. To increase the mist output, turn the MIST adjustment knob clockwise. To decrease mist output, turn the MIST adjustment knob counter-clockwise.

Mist Temperature Setting

When the humidifier is powered ON, it will be operating on the default setting—Cool Mist. To change the Mist Temperature from Cool Mist to Warm Mist, press the WARM MIST button. The mist temperature will change to Warm Mist, and the WARM MIST button will be illuminated red. To change the Mist Temperature back to Cool Mist, press the WARM MIST button again. The mist temperature will change to Cool Mist, and the light in the WARM MIST button will turn off.

NOTE: Once warm mist is selected, it will take 20 minutes before the mist becomes warm.

Night Light

Press the NIGHT LIGHT button to turn on the night light. The surround around the POWER/MIST knob will glow softly.

How to Fill

CAUTION: Before filling the unit with water, turn the power off and unplug the unit from the outlet.

NOTE: Always use two hands to carry the water tank.

1. Grasp the tank handle with both hands and lift it up from the humidifier base. Remove only one tank at a time.
2. Turn the tank upside down and remove the tank cap by turning it counter-clockwise.
3. Fill the water tank with clean, cool water (not cold). It is recommended to use distilled water if you live in a hard water area.
4. Replace the tank cap by turning clockwise until tight.
5. Install both tanks back on the base of the unit. Make sure the tanks are firmly seated.

NOTE: This unit uses water from one tank at a time. It will use all the water from one tank before beginning to pull water from the other tank.

NOTE: It is normal to have a small amount of water in the base during and after use.

About White Dust

The use of high mineral content hard water may cause a white mineral residue to accumulate on surfaces in the room near the humidifier. This mineral residue is commonly called “white dust.” The higher the mineral content (or, the harder your water is), the greater the potential for white dust. The white dust is not caused by a defect in the humidifier; it is caused only by minerals suspended in the water.

How and Why To Use Demineralization Cartridges

The HoMedics demineralization cartridge helps reduce the potential for white dust, a deposit of minerals left behind from using hard water in your humidifier. The cartridge should be replaced every 30–40 fillings. The cartridge may need to be replaced more often if you are using very hard water. Replace the cartridge when you notice an increase in white dust build-up. If white dust still forms around the humidifier after a new cartridge has been installed, consider using distilled water.

To purchase new demineralization cartridges, model # UHE-HDC4, visit your retailer or www.homedics.com.

If you live in an area with hard water, or use a water softener, it is recommended to use distilled water for better results from your humidifier. Never use water softening additives in your humidifier.

Installation Instructions (Demineralization Cartridge)

1. Remove the demineralization cartridge from packaging and let it soak in water for 10 minutes.
2. Remove the tank from the humidifier base and turn it over.
3. Unscrew the tank cap by turning the cap counter-clockwise.
4. Fill the tank with water as shown in the “How to Fill” section of the instructions.
5. Add the soaked demineralization cartridge into the tank.
6. Replace the tank cap by turning clockwise.
7. Place the tank back on the base.

Cleaning and Care

CAUTION: Before cleaning the unit, turn the power off and unplug the unit from the outlet.

To Clean the Tank

Remove the tank from the humidifier base by lifting it from the main unit. Unscrew the tank cap and rinse the inside of the tank with clean water. To remove any scale or build-up, use a 50/50 mixture of vinegar and lukewarm water to clean the inside of the tank. It is suggested to clean the water tank once every two to three weeks, depending on your water conditions.

To Clean the Ultrasonic Membrane

Pour a 50/50 mixture of vinegar and water onto the surface of the ultrasonic membrane, then soak for five minutes. Brush clean with a soft-bristle brush and rinse. NEVER touch the ultrasonic membrane with your fingers, as the natural oils in skin can damage the membrane. It is suggested to clean the membrane once every two to three weeks, depending on your water conditions.

NOTE: Never submerge the base in water or any liquid.

To Clean the Surface

Clean the surface of your humidifier with a clean, damp, soft cloth as often as needed.
