HOW TO USE

Use your favorite essential oil to deliver aroma into the air.
NOTE: For use with the included HoMedics essential oil pads only.
NOTE: Do not leave a filled essential oil pad in the oil tray of the humidifier if it will be out of use for a long period of time.
ARE ESSENTIAL OILS SAFE TO USE AROUND PETS?
We should always exercise caution when using essential oils around our pets. Keep all essential oil and aromatherapy products (like diffusers) out of reach of pets. Keep open bottles away from pets to avoid internal consumption. We do not recommend the topical use of essential oils on pets, as they have a strong sense of smell and cannot get rid of the oil if they don’t like it or it is disturbing them. When diffusing essential oils around pets, always diffuse in a well-ventilated area and leave an option for them to remove themselves from the space, such as leaving a door open. Every animal is different, so carefully observe how each animal responds when introducing an essential oil for the first time. If irritation occurs, discontinue the use of the essential oil. We recommend seeking medical attention if ingestion of essential oil occurs.
ADDING ESSENTIAL OILS
WARNING: PUTTING OIL ANYWHERE BUT THE OIL TRAY WILL DAMAGE THE HUMIDIFIER.
- The oil tray is located on the back of the humidifier.
- Push to open and remove the tray. Place 1 essential oil pad (3 included) into the oil tray.
- Add 5-7 drops of essential oil to the pad. You may use more or less depending on personal preference.
WARNING: Only place essential oil on the pad and NOT directly into the tray.
- Place the oil tray back in its compartment and push to close. The scent will start automatically when the mist is turned on.
ABOUT WHITE DUST
Use of high mineral content hard water may cause a white mineral residue to accumulate on surfaces in the room near the humidifier. The 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 will help reduce the potential for white dust. 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 buildup. If white dust still forms around the humidifier after a new cartridge has been installed, consider using distilled water. If you live in an area with hard water or use a water softener, we recommend using distilled water for better results from your humidifier. Never use water-softening additives in your humidifier.
INSTALLATION INSTRUCTIONS
- Remove demineralization cartridges from packaging and let them soak in water for 10 minutes.
- Fill the tank with water as shown in the How to Fill section of the instructions.
- Add the soaked demineralization cartridge into the tank.
To purchase genuine HoMedics Replacement Essential Oil Pads (model #UHE-PAD1) or HoMedics Essential Oils, contact your local retailer or visit www.homedics.com (US), www.homedics.ca (CAN). To purchase new Demineralization Cartridges, Model # UHE-HDC4, go to the retailer where you purchased your humidifier, or visit www.homedics.com (US), www.homedics.ca (CAN).
CLEANING AND CARE
CAUTION: Before cleaning the unit, turn power off and unplug unit from the outlet.
CLEANING THE TRANSDUCER/ULTRASONIC MEMBRANE
The transducer/ultrasonic membrane must be cleaned to remove water mineral deposits when the clean transducer/ultrasonic membrane indicator is illuminated on the display. Failure to do so may cause reduced or no mist output.
- Remove the tank cover and set aside. Lift the tank from the humidifier.
- Remove the tank and pour out any water remaining in the tank.
- Pour out any remaining water inside the water reservoir.
- Clean the transducer/ultrasonic membrane with a 50/50 mix of white vinegar and water on a cotton swab. Wipe off with a damp cotton swab. NEVER touch the transducer/ ultrasonic membrane with your fingers; the natural oils in the skin can damage the surface. NEVER submerge the base in water or any other liquid.
- After cleaning, reassemble the humidifier, fill with water, plug in, and turn on.
- Press and hold the clean transducer/ultrasonic membrane button, until the clean indicator turns off.
TO CLEAN THE FLOAT
Clean the float hinge with a 50/50 mix of white vinegar and water to remove any calcified water minerals as necessary.
TO CLEAN THE TANK AND WATER OUTLET
Remove the tank cover and water tank from the humidifier base. Pour out any remaining water. Rinse inside the tank with clean water. Press
the plunger to let clean water run through the water outlet. Every day: Empty and rinse the tank and tank cover before refilling. Press the plunger and let water run through the water outlet. Every week: To remove any scale or buildup, use a 50/50 mixture of white vinegar and lukewarm water to clean the inside of the tank. Press the plunger to let the mixture run through the water outlet.
TO CLEAN THE OIL TRAY
Open the oil tray and remove the pad. Essential oil pads should be changed when switching to a different essential oil scent. If continuing
to use the same scent, set the essential oil pad aside for reuse. Wipe down the inside of the oil tray with a soft cloth. Place the essential oil pad back in the tray and close.
NOTE: Leave the essential oil pad out of the oil tray when storing.
TO CLEAN THE SURFACE
Clean the surface of the unit with a soft, damp cloth. Before storing: Clean the tank, water outlet, water reservoir, float, tank cover, and the transducer/ultrasonic membrane with a 50/50 mixture of white vinegar and water. Be sure to rinse and let all parts dry completely before storing. Clean the oil tray with a soft cloth. After storing: Rinse the tank with water prior to operating.
