SAFETY INFORMATION

To reduce the risk of fire, electric shock, or other injury, follow all instructions and safety guidelines.

General Safety

• Only use the humidifier as described in this manual.
• Place the humidifier and cord so that it will not be knocked over. Do not place near large pieces of furniture or in high-traffic areas.
• When not in use, turn the humidifier off and disconnect from power by removing the plug from the outlet.
• Do not use the humidifier in wet environments.
• Keep the humidifier out of reach from children.
• To avoid risk of electric shock, always unplug the humidifier from the power outlet before cleaning it or detaching the water tank from the base.
• Always make sure the humidifier is placed on a flat, level surface before operation.
• Do not place the humidifier near sources of heat, such as stovetops, ovens, or radiators.
• Do not place the humidifier directly on floors, carpets, or rugs. Only place on water-resistant surfaces.
• Do not place foreign objects into the humidifier’s base or water tank.
• Do not use attachments that are not recommended by Levoit for the humidifier.
• Do not cover the mist outlet while the humidifier is on. Doing so may damage the humidifier.
• Do not allow water or other liquids inside the air vent.
• Remove the water tank from the base before moving the humidifier.
• Do not immerse the humidifier base, power cord, or plug in water.
• Always allow the humidifier to completely cool before cleaning.
• Do not use detergents to clean the humidifier. Only use distilled white vinegar.
• If the humidifier is damaged or is not functioning properly, stop using it and contact Customer Support immediately (see 14).
• Not for commercial use. Household use only.

Plug and Cord

• Do not handle the power cord or plug with wet hands. Keep the plug and power cord away from liquids.
• Ensure that the plug fits properly into a polarized socket.
• The humidifier has a polarized plug (one prong is wider than the other), which fits into a polarized outlet only one way. This is a safety feature to reduce the risk of electric shock. If the plug does not fit, reverse the plug. If it still does not fit, do not use the plug in that outlet. Do not bypass this safety feature.

GETTING STARTED

1. Remove all packaging. Choose a hard, flat location for the humidifier at least 6 in / 15 cm away from any walls, furniture, bedding, and appliances. The surface must be water-resistant.
   [Figure 1.1] Note: Do not place the humidifier on towels, carpets, rugs, floors, or any surfaces with fibers. This will block the air inlet at the bottom of the humidifier and cause overheating. [Figure 1.2]

2. Take the water tank off of the base and remove all tape. [Figure 1.3]

Filling & Refilling

1. Remove the top cover from the water tank. Fill the tank with room temperature water. Do not fill with warm or hot water.[Figure 1.4] Note:
   • We recommend using purified water.
   • Avoid using tap water, because
   the mineral content is too high and will create white dust around the humidifier.

2. Optionally, add 10–15 drops of essential oil into the base chamber. [Figure 1.5] Note: For best results, we recommend using pure essential oil.

3. Place the top cover back onto the water tank. Make sure the tank is properly placed on the base by aligning the indicator marks. [Figure 1.6]

4. Plug in the humidifier.

USING YOUR 2-IN-1 HUMIDIFIER & DIFFUSER

Note :

• If there is no water in the tank, the humidifier will not turn on and will blink. Fill the water tank (see Getting Started, 5).
• Keep the humidifier stable while using, or water may spill.
• Do not block the mist outlet. This will damage the humidifier. [Figure 2.1]

Mist Level

1. Press power button once. The humidifier will start on the low mist level. [Figure 2.2]
2. Press power button repeatedly to cycle through mist levels (low, medium, high) and to turn the humidifier off. [Figure 2.2]

Intelligent Sleep Mode

Intelligent Sleep Mode turns off all display lights and uses a humidity sensor to automatically adjust the mist level to maintain a 60% relative humidity (RH) while you sleep.

1. Press power buton  to turn on the humidifier. Note: The humidifier must be on to start Sleep Mode.

2. Press  moon to start Sleep Mode. After 5 seconds, all display lights will turn off.

3. Press moon a second time (or press power button) to cancel Sleep Mode. The humidifier will go back to the previously set mist level
   Note :

   • Excessive humidity can cause health issues and mold growth. If the relative humidity in your room is over 60%, use the low mist setting or turn off the humidifier.

Important Tips

• Never pour water directly into the base chamber. Only add water to the water tank. [Figure 2.3] The humidifier will automatically release the correct amount of water into the base chamber.
• Avoid moving or shaking the humidifier.[Figure 2.4] This may cause the water tank to release too much water into the base chamber.
• Before moving the humidifier, turn it off, unplug it, and remove the water tank.
• If your humidifier doesn’t produce mist correctly, check the max water line to see if there is too much water in the base chamber. [Figure 2.5] Pour out any extra water if water is over the max line
  Note: The max water line is only for this purpose. Do not pour water into the base.

CARE & MAINTENANCE

Note:

• All maintenance should be done on a water-resistant surface, such as a kitchen counter.
• Change the water daily to avoid bacteria growth.
• Use a tissue or cloth to clean the mist outlet regularly.
• If not using the humidifier for 1 week or longer, do not leave water inside. Dry and store instead.

Cleaning

Clean your humidifier every week, and when you’re ready to store it.

Note:

• Never immerse the base in water or liquid. Do not place the base in a dishwasher.
• Do not use detergents to clean the humidifier.

1. Unplug the humidifier. [Figure 3.1]
2. Remove and wash the top cover. [Figure 3.2]
3. Remove the water tank from the base. Pour out all water from the tank and base. [Figure 3.3] Note: Do not let water inside the air outlet or near the control panel. [Figure 3.4]
4. Rinse the tank and base chamber with room temperature water. [Figure 3.5]
5. To remove any scale buildup inside the water tank or base chamber, soak with distilled white vinegar and wipe with a cloth and cotton swab.
6. If you used essential oils in the humidifier, fill the water tank and the base chamber with distilled white vinegar and allow to soak.
7. To remove the mist tube for cleaning, flip the tank over. Push in the tab on the mist tube and pull out the mist tube.[Figure 3.6 – Figure 3.7] To replace, see Installing the Mist Tube.
8. Rinse all parts and pour out remaining water.
9. Dry all parts with a cloth. Make sure all parts are completely dry.

Installing the Mist Tube

Make sure the mist tube is in place. If it is not, the humidifier will not create mist.

1. Put the mist tube into place inside the water tank, then align the top of the mist tube with the mist outlet. [Figure 3.8]
2. Press the mist tube down until the tab snaps into place. [Figure 3.9 – Figure 3.10]

Storing
Follow the cleaning instructions (see 9) and allow all parts to dry completely before storing. Store in a cool, dry location.

TROUBLESHOOTING

Problem                            Possible Solution

Humidifier doesn’t turn on, or the buttons do not work.| Unplug the humidifier and plug it back in. Press            to turn the humidifier on.
Fill the water tank if it is empty.
Little or no mist comes out.| Press     to use a higher mist setting.
Make sure the mist tube is correctly installed (see Installing the Mist Tube , 10).
Make sure the water level in the base is not too high.
Water may be dirty, and there may be mineral buildup inside the base. Clean the transducer with a cleaning brush and white vinegar and make sure all parts are properly installed (see Care & Maintenance, 9). Fill with clean water.
Make sure the mist outlet and air inlet are not blocked (see

Getting to Know Your 2-in-1 Humidifier & Diffuser, 4).

Humidifier is hot (or the water inside is hot), and little or no mist comes out.| Make sure the air inlet at the bottom of the humidifier and the mist outlet at the top of the humidifier are not blocked. Do not place the humidifier on floors, carpets, rugs, or surfaces with fibers that may block the air inlet.
Make sure the mist tube is correctly installed (see Installing the Mist Tube , 10). If the mist tube is not in place, the humidifier

will not create mist, and the water temperature will rise. This is not dangerous, but the humidifier will not work correctly until the mist tube is put in place.

Humidifier uses water too quickly.| The humidifier uses up water based on the environmental temperature and humidity. If your environment is cold and/or dry, the humidifier will run out of water faster.
Problem                            Possible Solution

Humidifier produces an unusual smell.| If the humidifier is new, remove the top cover, and place the water tank in a cool, dry place for 12 hours.
Water may be dirty or has been sitting in the tank for a long period of time. Clean the humidifier (see Care & Maintenance,

9. and refill with clean water.

If essential oils were diffused, clean with white vinegar (see Care & Maintenance, 9), and allow the humidifier to dry.
White dust appears around the humidifier.| This is caused by using water with high mineral content. Use purified water to fill the humidifier.
Clean the humidifier (see Care & Maintenance, 9).
Water leaks from the humidifier.| Make sure the tank is properly placed on the base by aligning the indicator marks (see 5).
Make sure the sealing ring inside the water tank is securely in place. If necessary, clean the sealing ring and make sure it can open and close normally.
Make sure the mist tube is correctly installed and securely in place (see 10).
Make sure the float is correctly installed and securely in place.
When humidity is too high, water may condense on the surface of the humidifier or surrounding area. Turn down the mist level or turn off the humidifier.
Water outlet may be blocked by mineral buildup. Clean the water outlet valve assembly with vinegar.
Essential oils have little or no smell.| Make sure you’ve added 10–15 drops of oil into the base chamber. For best results, we recommend using pure essential oil.
