READ AND SAVE THESE INSTRUCTIONS

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.
• Do not open the base or remove the water level sensor for selfservicing.
• Always unplug your humidifier from the power outlet before cleaning your humidifier or detaching the water tank from the humidifier base.
• Always make sure to place the humidifier on a flat, level surface before operation.
• Only fill the water tank with clean water. Never fill the water tank with any other liquids.
• 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.
• Do not use other items as replacement parts for this product.
• Do not cover the nozzle while the humidifier is on. Doing so may damage the humidifier.
• Remove the water tank from the base before moving the humidifier.
• Do not immerse the humidifier base, power cord, or plug in water.
• If the humidifier is damaged or is not functioning properly, stop using it and contact Customer Support immediately.
• Not for commercial use. Household use only.

Risk of Leaks and Electric Shock

• Do not add essential oils, supplemental water treatment liquids, or water filters into the water tank or base chamber. This will damage the humidifier and cause leaks. Only add essential oils to the aroma pad.

Plug & Cord

• Ensure that the plug fits properly into a polarized socket.
• Do not handle the power cord or plug with wet hands. Keep the plug and power cord away from liquids.
• Your 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.

VESYNC APP SETUP

Note: Due to ongoing updates and improvements, the VeSync app may be slightly different than shown in the manual. In case of any differences, follow the in-app instructions.

1. To download the VeSync app, scan the QR code or search "VeSync" in the Apple App Store^® or Google Play Store.
   
   
   
   
   Note: For Android™ users, choose "Allow" to use VeSync.
2. Open the VeSync app. If you already have an account, tap Log In. To create a new account, tap Sign Up.
   Note: You must create your own VeSync account to use third-party services and products. These will not work with a guest account. With a VeSync account, you can also allow your family and friends to control your smart humidifier.
3. Follow the in-app instructions to set up your smart humidifier.
   Note: You can use the VeSync app to connect your smart humidifier to Amazon Alexa or Google Assistant™. Follow the in-app instructions to connect VeSync to your voice assistant.

USING YOUR SMART HUMIDIFIER

Note: Using the VeSync app allows you to control your smart humidifier remotely and access additional functions and features.

1. Plug in the humidifier. Press to turn your humidifier on.
   Note: If there is no water in the tank, will flash 10 times, and the humidifier will turn off. Fill the water tank (see Getting Started).
2. Tap repeatedly to cycle through mist settings: Auto Mode, Low, Medium, and High. [Figure 3.1]
   
   Note:
   • The humidifier will not mist in Auto Mode if the humidity level is above 50%. If you want the humidifier to keep misting, change the mist setting, or change the Auto Mode settings in the VeSync app.
3. Rotate the nozzle to adjust the direction of the mist. [Figure 3.2]
   
   
4. Optionally, use the controls to activate Sleep Mode, turn the night light on/off, and more (see Controls).
5. When your room has reached your preferred humidity level, turn the humidifier to a lower setting, or turn it off. A healthy humidity level is between 40% and 50%. [Figure 3.3]
   
   Note: You can also use Auto Mode to keep the humidity level between 40% and 50%.
6. Press to turn your humidifier off.
   Note: If there is no water in the tank or the tank is removed, the humidifier will stop misting, will flash 10 times, and the humidifier will turn off. Refill the tank and properly place it on the base to use your humidifier.

Sleep Mode

Sleep Mode changes the humidifier's mist setting to Auto Mode, turns off the display lights, and turns off the night light.

• When Sleep Mode is on, you can press to turn the night light on/off. The humidifier will stay in Sleep Mode.

Auto Mode

Auto Mode uses the humidifier's sensor to automatically adjust the mist level (or turn it off) to maintain a comfortable and healthy level of humidity.

• Auto Mode automatically adjusts the mist level to maintain 40–50% relative humidity. You can change the target humidity level in the VeSync app.
• By default, Auto Mode uses Automatic Stop. The humidifier will stop misting when the highest target humidity level is reached. If the humidity drops below the target humidity level, the humidifier will begin misting again.
• If Auto Mode is selected when the humidity is higher than the target humidity range, the humidifier will not start misting until the humidity lowers.
• In the VeSync app, you can turn Automatic Stop on/off. If Automatic Stop is off, the humidifier will keep running on Low mist level when the highest target humidity level is reached.

VeSync App Functions

The VeSync app allows you to access additional smart functions, including those listed below.

Remote Control

• Turn the humidifier on/off from your phone.
• Cycle through mist levels and turn on/off Auto Mode and Sleep Mode from your phone.
• Turn the display lights and night light on/off from your phone.
• Customize Auto Mode settings like target humidity and auto-off.

Monitor Humidity Levels

• Check current humidity levels in the humidifier's environment.

Set Timers & Schedules

• Program individual timers or create a schedule for your smart humidifier.

Third-Party Voice Control

• Compatible with Amazon Alexa and Google Assistant for voice commands.

Note: The VeSync app is continually updated and app features will expand.

Important Tips

Your humidifier must have the correct level of water in the base chamber to work properly. If there is too much water in the base chamber, the humidifier cannot create mist.

• Never pour water directly into the base chamber. [Figure 3.4] Only add water to the water tank. The humidifier will automatically release the correct amount of water into the base chamber.
  
  
• Avoid moving or shaking the humidifier. [Figure 3.5] 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. Pour out extra water if water is over the max line. [Figure 3.6]
  

Note: The max water line is only for this purpose. Do not pour water into the base chamber.

Using the Aroma Box

Your humidifier can be used for aromatherapy.

1. Push the aroma box at the back of the base and pull it out. [Figure 3.7]
   
   
2. Put 8–10 drops of essential oil on the aroma pad. [Figure 3.8]
   
   
3. Place the aroma box into the humidifier.
4. Turn on the humidifier. The humidifier will automatically diffuse aroma when used.

Note:

• Do not add essential oils, water treatment liquids, or third-party water filters into the water tank or base chamber. Only add essential oils to the aroma pad.
• The aroma pads can be cleaned and reused after diffusing essential oils (see Cleaning the Aroma Pad).
• The aroma is intended to be light. This humidifier is not an aroma diffuser.

CARE & MAINTENANCE

Note:

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

Cleaning

You should 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 any part of the humidifier in a dishwasher.
• Do not use detergents to clean the humidifier.

1. Unplug the humidifier.
2. Remove and rinse the water tank cover. [Figure 4.1]
   
   
3. Remove and rinse the dust cover if necessary. [Figure 4.2]
   
   
4. Remove the water tank from the base and pour out any water from the tank and base chamber. [Figure 4.3]
   Note: When pouring out water, hold down the float to ensure that it does not fall out of the base chamber.
   
   
5. Rinse the tank and base chamber with room temperature water. [Figure 4.4]
   
   
6. To descale the humidifier:
   1. Fill the tank with 3 US cups / 710 mL of distilled white vinegar. [Figure 4.5]
      
      
   2. Replace the tank cover and swish the vinegar around the tank. [Figure 4.6]
      
      
   3. Place the tank on the base and soak for 15–20 minutes. Vinegar will drain into the base chamber and loosen scale (mineral buildup) in the tank and in the base chamber (including the transducer and float). [Figure 4.7]
      
      
   4. Remove the tank, remove the tank cover, and pour out any vinegar. [Figure 4.8]
      
      
   5. Flip the tank over and remove the noise silencer. To remove the noise silencer, press the release tab and gently pull away from the humidifier. [Figure 4.9]
      
      
   6. Remove the float from the base chamber by pulling up the larger side of the float [Figure 4.10] and pulling the shaft out from the float brackets. One side of the float brackets is open (U-shaped) to allow the shaft to be removed. [Figure 4.11]
      
      
   7. Place the float and noise silencer in a small container. Fill with enough vinegar to cover them. Soak for 15–20 minutes. [Figure 4.12]
      
      
   8. Use a soft cloth and the included cleaning brush to remove scale from all parts. [Figure 4.13]
      
      
   9. Rinse all parts until any vinegar smell is completely gone. [Figure 4.14]
      
      
7. Dry all parts with a cloth. Make sure all parts are completely dry before reassembling or storing.

Cleaning the Aroma Pad

1. Press the aroma box to release it from the base, and pull it out. [Figure 4.15]
   
   
2. Remove the aroma pad and rinse under warm, running water. [Figure 4.16]
   
   
3. Dry with a clean cloth and place it back into the aroma box. [Figure 4.17]
   

Note: Do not pour liquid cleaners or detergents into the aroma pad or box.

Reassembling

1. Flip the water tank over and place the noise silencer back into the tank. [Figure 4.18]
   
   
2. Place the float back into the base chamber:
   1. Make sure the correct side of the float is facing up. [Figure 4.19]
      
      
   2. Insert the smaller prong into the closed side of the float brackets. [Figure 4.20]
      
      
   3. Place the larger prong into the open (U-shaped) side of the float brackets.
3. Place the tank back on the base. Refill the tank, if necessary.
4. Place the tank properly on the base and place the tank cover on the water tank.

Storing

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