IMPORTANT SAFETY INSTRUCTIONS
READ AND SAVE THESE SAFETY INSTRUCTIONS BEFORE USING THIS HUMIDIFIER
When using electrical appliances, basic precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons, including the following:
- The humidifier should ALWAYS be placed on a firm, flat, waterproof surface at least four feet (1.2m) away from bedside, 12 inches (30cm) from the wall. KEEP OUT OF REACH OF CHILDREN AND PETS.
- Be sure the humidifier is in a stable position and the power cord is away from heated surfaces and out of the way to prevent the humidifier from being overturned.
- DO NOT leave the humidifier unattended in a closed room. The air can become saturated and leave condensation on walls and furniture. If room becomes saturated, open the door and turn the humidifier off or down.
- Before using the humidifier, extend the cord and inspect for any signs of damage. DO NOT use the unit if the cord has been damaged. DO NOT operate with power cord coiled or with twist tie in place.
- The humidifier has a polarized plug (one blade is wider than the other) as a safety feature. This plug will fit into a polarized outlet only one way. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. DO NOT attempt to defeat this safety feature.
- CAUTION: To avoid fire or electric shock hazard, plug the humidifier directly into a 120V AC electrical outlet. To avoid risk of fire, electric shock, or personal injury, DO NOT use an extension cord or power strip.
- he humidifier should ALWAYS be unplugged and emptied when not in operation or while being cleaned. Turn off and unplug humidifier before moving. DO NOT move or tilt humidifier while it is in operation. Plug and unplug unit with dry hands. NEVER pull by cord.
- DO NOT operate the humidifier without water. Turn off and unplug unit when tank is empty and the reset light is on.
- Humidifier requires regular cleaning. Refer to and follow cleaning instructions.
- DO NOT operate outdoors; this humidifier is intended for indoor residential use only.
- DO NOT cover or insert objects into any openings on the unit. DO NOT block intake or output vents.
- DO NOT attempt to repair or adjust any electrical or mechanical functions on this humidifier. Doing so will void your warranty.
- DO NOT add any essential oils or medications (e.g. Kaz Inhalant or Vicks VapoSteam®) into Water Tank/Reservoir.
- DO NOT touch the steam vapor. Steam can cause burns.
- DO NOT operate without the Top Cover in place on top of the Mist Chimney.
- For Residential Use Only
SAVE THESE INSTRUCTIONS.
GETTING TO KNOW YOUR WARM MIST HUMIDIFIER
How it Works
Water from the tank is released into the boiling chamber where it is heated to a steam vapor. The boiling action kills 99.9% of bacteria in the water.1 The steam vapor mixes with dry air in the mist chimney and warm moist air is released into the room. When the humidifier runs out of water, the reset light will illuminate and the unit will shut off. Be careful not to over-humidify; if condensation forms around the unit or on walls and surfaces, turn the humidifier off or to a lower setting.

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. This is not a diffuser – the oil does not come in contact with water but is passively evaporated into the air. Essential oil and inhalants are not included.
- Add a few drops of essential oil or liquid inhalant in the Cup.
WARNING: DO NOT pour any liquids into the Water Tank or Mist Outlet. DO NOT ADD LIQUID INHALANTS, ESSENTIAL OILS OR ANY ADDITIVES TO THE WATER. DOING SO CAN HAVE ADVERSE EFFECTS ON THE HUMIDIFIER AND VOID THE WARRANTY.

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
- Turn off and unplug humidifier. NEVER clean the humidifier when it is running. If the humidifier has recently been in use, wait at least 20 minutes for unit to cool before beginning cleaning process.
- Disassemble by removing Top Cover and internal components.
- Mist Chimney – twist left and pull straight up to remove.
- Heating Element Cover – pull red latch toward front of unit and lift straight up to remove.
- Water Level Float – pull red Float Tab straight up to remove.
Scale Removal
Keeping the Heating Element free of scale buildup will help the humidifier to run efficiently.
- Pour 3 cups (0.7L) of undiluted, distilled white vinegar into the Water Tank/Reservoir. Let soak for 20 minutes to loosen scale on Heating Element.
- Wet the bristles of a soft brush with vinegar and gently scrub the surface of the Heating Element to remove mineral deposits.
DO NOT USE HARD BRUSHES, STEEL WOOL OR OTHER HARD ABRASIVES ON THE HEATING ELEMENT. DOING SO WILL DAMAGE THE PROTECTIVE COATING AND CAUSE THE HEATING ELEMENT TO FAIL. - Empty vinegar by pouring from the side of the humidifier into the sink.
- Pour 3 cups (0.7L) of water into the Water Tank/Reservoir, lightly swish water and pour out. Repeat until the smell of vinegar is gone. To remove scale from other components, soak separately in vinegar or wash in top rack of dishwasher.
Disinfecting
Before starting the disinfecting process, follow steps 1-2 in the Before Cleaning section.
NOTE: Bleach may stain clothes. Rubber gloves are recommended to protect your hands.
- Add 1/2 teaspoon of bleach to 1/2 gallon (1.9L) of water.
NOTE: Using more than 1/2 teaspoon of bleach to 1/2 gallon of water may result in damage to the humidifier. - Pour the bleach solution into the Water Tank/Reservoir. Let soak for 20 minutes.
- Empty bleach solution by pouring from the side of the humidifier into the sink.
- Pour 3 cups (0.7L) of water into the Water Tank, lightly swish water and pour out. Repeat until the smell of bleach is gone.
