GETTING TO KNOW YOUR COOL + WARM MIST HUMIDIFIER

How it Works

• A. Water drains into the Reservoir.
• B. On cool mist setting, a Nebulizer vibrates at an ultrasonic frequency and produces cool, ultrafine mist that travels up the Mist Chimney where it enters the room.
• C. On warm mist setting, water in the Boiling Chamber is boiled to create a steam vapor.
• D. On warm mist setting, the steam vapor mixes with a small amount of cool mist to produce soothing, warm (not hot) comforting mist.

WAY MIST OUTLET

This humidifier features a 2-Way Mist Outlet that allows you to direct mist in in two directions. Positioning both openings in the same direction results in a strong mist plume into the room. Separating the mist outlets allows for pointing the mist in two directions for wider distribution.

USING THE ESSENTIAL OIL CUP

This humidifier features an Essential Oil Cup that can be used with your favorite essential oil or liquid inhalant (like Vicks VapoSteam®) for added enjoyment. The cup is heated to help evaporate the oil. This is not a diffuser the oil does not come in contact with the water but is passively evaporated into the air. Essential oil and inhalant are not included.

1. Add a few drops of essential oil or liquid inhalant in the Essential Oil Cup.
   WARNING: DO NOT ADD ESSENTIAL OILS, LIQUID INHALANTS OR ANY ADDITIVES TO THE WATER. DOING SO CAN DAMAGE THE HUMIDIFIER AND VOID THE WARRANTY.

2. To clean the Essential Oil Cup, wait 5 minutes for it to cool. Then gently wipe residue from the cup with a soft cloth

HARD WATER AND YOUR HUMIDIFIER

High mineral content in your water, also known as hard water, may cause a white mineral residue to accumulate on surfaces in the room near the humidifier. This mineral residue is commonly referred to as white dust. The higher the mineral content (hardness) of your water, the greater the potential that an ultrasonic humidifier may produce white dust.

With warm mist humidifiers, the minerals can cling to the heating element which can prevent it from running efficiently. It is important to clean the Heating Element and Nebulizer regularly.

White dust is not a result of a defect or flaw in the humidifier. It is a result of the amount of minerals suspended in the water you are using. Tap water can be diluted with distilled water to reduce white dust.

CLEANING YOUR HUMIDIFIER

To keep your humidifier running efficiently, clean it regularly. Weekly cleaning is recommended. All maintenance should be done in the kitchen or bathroom on a water-resistant surface near a faucet.

To properly clean your humidifier, we recommend the separate processes of Scale Removal and Disinfecting. These two processes must be performed separately.

Before Cleaning

If the humidifier has recently been in use on the warm setting, wait at least 20 minutes for unit to cool before beginning the cleaning process.

1. Turn off and unplug the humidifier. Never clean the humidifier when it is running.
2. Remove the Water Tank and empty it completely. Remove any accessories from the water tank.
3. Ensure Chimney is removed (See Disassembly below), then pour water from the Base into the sink. Be sure to pour out of the side of the Base, as indicated by an arrow, to avoid leaking into the Control Panel. Replace Chimney and Chimney Cover before beginning the cleaning process.

Disassembly

1. Mist Chimney Cover – a) slide red latch and b) remove.
2. Mist Chimney – grasp Chimney and pull straight up.
3. Mist Outlet – pull out of Mist Chimney Cover (optional).

Reassembly

1. Replace Mist Chimney.
2. If removed, replace Mist Outlet on top of Mist Chimney Cover.
3. Slide the red latch a) and place the Mist Chimney Cover in place b); secure the latch

Scale Removal (Mineral Buildup)

Follow steps 1-3 in Before Cleaning section, then follow the additional steps below.

1. Pour 2.5 cups (.6 liters) of undiluted distilled white vinegar into the Water Tank.

2. Replace Tank Cap and swish vinegar in Tank to coat the inside of the Water Tank.

3. Place Tank on Base, allowing vinegar to drain into the Water Reservoir. The vinegar will loosen mineral buildup on the Nebulizer, Heating Element, Float, Chimney bottom, and in the bottom of the Tank. Soak for 20 minutes.

4. Remove Water Tank and empty vinegar into sink.

5. Remove Mist Chimney Cover, Mist Chimney and Mist Outlet to access Reservoir area (see Disassembly instructions). Use Cleaning Brush to loosen mineral buildup in corners of Reservoir, Water Path and Boiling Chamber.

6. Gently wipe Nebulizer, Heating Element and Reservoir area with a soft cloth or paper towel to remove loosened minerals.
   NOTE : Nebulizer is fragile. DO NOT apply extreme pressure.

7. Pour vinegar from the Base into the sink. Be sure to pour from the side as indicated by an arrow to avoid leaking into the Control Panel. Rinse the Tank and Reservoir with clean water until the smell of vinegar is gone.

CAUTION : DO NOT SUBMERGE BASE IN WATER. DOING SO WILL DAMAGE THE HUMIDIFIER AND VOID THE WARRANTY.

Disinfecting

Before starting the disinfecting process, follow Steps 1-3 in the Before Cleaning section.

NOTE : Bleach may stain clothes. It is recommended to wear rubber gloves during this process to protect your hands.

1. Add 1 teaspoon of bleach to 1 gallon (3.8L) of water and add to Water Tank.
2. Replace Tank Cap and swish bleach solution in Tank to coat the inside of the Water Tank.
3. Place Tank on Base, allowing solution to drain into the Water Reservoir. Soak for 20 minutes.
4. Remove Water Tank and empty solution into sink.
5. Ensure Chimney is removed, then pour solution from the Base into the sink. Be sure to pour out of the side of the Base, as indicated by an arrow, to avoid leaking into the Control Panel.
6. Rinse Tank and Reservoir area with clean water until the smell of bleach is gone

CAUTION: DO NOT SUBMERGE BASE IN WATER. DOING SO WILL DAMAGE THE HUMIDIFIER AND VOID THE WARRANTY.

END-OF-SEASON CARE AND STORAGE

Follow the cleaning instructions when the humidifier will not be used for at least one week, or at the end of the season. At the end of the season, remove any accessories from the humidifier. Dry the humidifier completely before storing.
