• 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

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.

Figure 3.3
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 o. Refill
the tank and properly place it on the base to use
your humidifier.
Note: Using the VeSync app allows you to control
your smart humidifier remotely and access additional
functions and features (see page 13).
Note: You can also use Auto Mode to keep the
humidity level between 40% and 50%.
Note: If there is no water in the tank, will flash
10 times, and the humidifier will turn o. Fill the
water tank (see Getting Started, page 8).
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.

Auto Mode
Sleep Mode
Auto Mode uses the humidifier’s sensor to
automatically adjust the mist level (or turn it
o) 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.
• In the VeSync app, you can turn
Automatic Stop on/o. If Automatic Stop
is o, the humidifier will keep running on
Low mist level when the highest target
humidity level is reached.
• 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.
Sleep Mode changes the humidifier’s mist
setting to Auto Mode, turns o the display
lights, and turns o the night light.
• When Sleep Mode is on, you can press
to turn the night light on/o. The
humidifier will stay in Sleep Mode.
Note: The VeSync app is continually updated and
app features will expand.
The VeSync app allows you to access

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 o,
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.

15
Using the Aroma Box
1. Push the aroma box at the back of the
base and pull it out. [
Figure 3.7 ]
Your humidifier can be used for
aromatherapy.
Figure 3.8
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 diuse 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 diusing essential oils (see
Cleaning the
Aroma Pad
, page 20).
• The aroma is intended to be light. This
humidifier is not an aroma diuser.

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 nozzle
regularly.
• If not using the humidifier for 1 week or longer,
do not leave water inside. Clean and dry the
humidifier instead.
Note: When pouring out water, hold down the
float to ensure that it does not fall out of the base
chamber.
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.
