Plug in the humidifier. Press to turn your humidifier on. The humidifier will automatically begin misting on high for 3 seconds, then change to the low mist setting.
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, page 9).
Tap repeatedly to cycle through mist settings: Auto Mode, Low, 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.
- For more information about Auto Mode, see page 13.
Rotate the nozzle to adjust the direction of the mist. [Figure 3.2]
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%.

Press to turn your humidifier off.
Note:
- If there is no water in the tank, 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.
- If the water tank is removed, will remain on until the tank is replaced.

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 from your phone.
Turn the display lights on/off from your phone.

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.

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.
For more safety information, see Maintenance Safety (page 5).

Cleaning
You should clean your humidifier water tank and base chamber every 3 days, and when you’re ready to store it.

Note:

Never immerse the base in water or liquid.
Do not use detergents to clean the humidifier.
The water tank, water tank cover, water filter housing, nozzle, float, and silencer are dishwasher safe.
Do not put the water filter in the dishwasher or it may become discolored.

Unplug the humidifier.
Remove and rinse the water tank cover. [Figure 4.1]
Remove the water tank from the base and pour out any water from the tank and base chamber. [Figure 4.2]
Note: When pouring out water, hold down the float to ensure that it does not fall out of the base chamber.
Remove the water filter assembly from the tank by rotating it anticlockwise and lifting it out. [Figure 4.3]
Cleaning (cont.)
Rinse the tank, water filter assembly, and base chamber with room-temperature water. [Figure 4.4]
To descale the humidifier: a. Remove the water filter from the tank. [Figure 4.5] Fill the tank with 710 mL / 3 US cups of distilled white vinegar. [Figure 4.6]
- Replace the tank cover and swish the vinegar around the tank. [Figure 4.7]
- 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 4.8]
  Cleaning (cont.)
