SAFETY INFORMATION (CONT.)
Electromagnetic Fields (EMF)
Caution: Risk of Leaks and
Electric Shock
This humidifier complies with all standards
regarding electromagnetic fields (EMF).
If handled properly and according to
the instructions in this user manual, the
appliance is safe to use based on scientific
evidence available today.
•
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.
Power & 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.
•
•
If the power supply cord is damaged, it
must be replaced by Arovast Corporation
or similarly qualified persons in order to
avoid an electric or fire hazard. Please
contact Customer Support
(see page 27).
Unplugging the power cord will disable
remote control of the humidifier and
temporarily disconnect the humidifier
from VeSync and other third-party apps.

•
Do not place the humidifier directly
on floors, carpets, or rugs.
4. Mist should be directed away from walls,
furniture, bedding, and appliances. Avoid
letting too much mist fall on the side of
the humidifier with the aroma box, as this
may interfere with the sensor inside the
aroma box.
Note: The humidity sensor and an air
inlet are both located inside the aroma
box. Placing the humidifier away from
walls will also ensure that the inlet and
sensor function properly.

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.
•
•
Do not place the humidifier on an
inclined surface.
Never pour water directly into the
base chamber. [Figure 4.1] 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.
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.
Empty any excess water from the base
chamber.
Figure 4.1
CARE & MAINTENANCE
Note:
Note:
•
All maintenance should be done on
a water-resistant surface, such as a
kitchen counter.
•
Never immerse the base in water or
liquid. Do not place any part of the
humidifier in a dishwasher.
•
•
•
Change the water daily to avoid
bacteria growth.
•
Do not use detergents to clean the
humidifier.
Use a tissue or cloth to clean the
nozzles regularly.
1. Unplug the humidifier.
If not using the humidifier for 1 week or
longer, do not leave water inside. Clean
and dry the humidifier instead.
Note: If you’ve been using the warm
mist setting, allow the humidifier to cool
before cleaning.
Cleaning
You should clean your humidifier every
week, and when you’re ready to store it.

2. Remove and rinse the water tank cover.
3. Remove the water tank from the base,
and remove the mist channel and mist
tube. [Figure 5.1] Pour out any water from
the tank and base chamber. If you’ve
used the warm mist setting, use caution
in case the water is still hot.
6. Detach the mist tube from the
mist channel by twisting the tube
counterclockwise. [Figure 5.1]
7. Remove the float, noise silencer,
absorption pad, and aroma box from the
base. [Figure 5.4]
Note: When pouring out water, hold
down the float to ensure that it does
not fall out of the base chamber.
4. Remove the water filter from the tank by
rotating it counterclockwise and lifting it
out. [Figure 5.2]
5. Remove the water filter sponge from
the water filter if necessary for cleaning.

TROUBLESHOOTING
Problem
Possible Solution
Humidifier doesn’t
turn on, or turns off
unexpectedly.
Plug the humidifier into a working outlet and turn it on.
Add purified water to the water tank.
Turn the mist level to a higher setting.
Fill the water tank.
Little or no mist comes
out.
There may be too much water in the base chamber. Empty the base
chamber. Refill the water tank (not the base chamber) and place the water
tank properly onto the base.
Make sure the air inlets on the bottom of the base and in the aroma box
are not blocked. The humidifier should not be set on carpet or other
surfaces that may block the air inlets.
Clean the humidifier (see Care & Maintenance, page 16). Make sure
the nozzles are not blocked or clogged.
Make sure the humidifier is on a level surface.
If the water tank or base was washed with detergent, rinse thoroughly with
clean water to remove any detergent.
Clean the water filter (see page 16) or replace the water filter sponge
with a new one. One replacement water filter sponge is included with this
humidifier. For information on additional replacements, contact Customer
Support (see page 27).
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.
Using the warm mist function will use up water faster.
Humidifier produces an
unusual smell.
If the humidifier is new, unplug and rinse all parts, then place in a cool, dry
place for 12 hours.
If essential oils were placed on the aroma pad, rinse the pad under clean
water and allow it to dry.
Clean the humidifier (see Care & Maintenance, page 16).

TROUBLESHOOTING (CONT.)
Problem
Possible Solution
Humidifier makes a loud
or unusual noise.
Make sure the water tank is properly in place (see Getting Started, page
8).
Set mist level to a lower setting.
Empty the base chamber. Refill the water tank (not the base chamber) and
place the water tank properly onto the base.
When using the warm mist function, the heating element may make a
gurgling noise if the water level is low. Add more water to the water tank.
The humidifier may be malfunctioning. Stop using the humidifier and
contact Customer Support (see page 27).
Mist leaks from the base.
Make sure the water tank is properly in place (see Getting Started, page
8).
White dust appears
around or in the
humidifier.
We recommend using purified to fill the humidifier. Avoid using water with
high mineral content, such as tap water.
Clean the humidifier (see Care & Maintenance, page 16).
Avoid running the humidifier in a room with over 60% relative humidity.
Wipe any excess water off the top and bottom of the base.
Do not shake the humidifier.
Water visibly leaks from
the humidifier.
Make sure to place the humidifier on a flat, level surface.
Check the water tank for leaks. If there are leaks, contact Customer
Support (see page 27).
The area around the
humidifier is damp or wet
from condensation.
Humidity may be too high. Turn down the mist level, turn off the humidifier,
or open a door or window to the room.
Open a window to ensure proper airflow for the humidifier, or move the
humidifier to a more well-ventilated room.
Make sure the water tank is properly in place (see Getting Started, page
8).
When replacing the water tank, wipe off excess water from the water tank
and base.
