Power & Cord
Electromagnetic Fields (EMF)
• Ensure that the plug fits properly
into a polarized socket.
• 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.
• Do not handle the power cord or
plug with wet hands. Keep the plug
and power cord away from liquids.
• 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 26).
• Unplugging the power cord
will disable remote control of
the humidifier and temporarily
disconnect the humidifier from
VeSync and other third-party apps.
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.

Note:
•
Never
immerse the base in water or liquid.
Do not
place any part of the humidier in a
dishwasher.
•
Do not
use detergents to clean the humidier.
Cleaning
You should clean your humidifier water tank
and base chamber every 3 days, and when
you’re ready to store it.
1. Unplug the humidifier.
2. Remove and rinse the water tank cover.
[
Figure 6.1
]
3. Remove the water tank from the base.
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.
4. Remove the water filter from the tank by
rotating it counterclockwise and lifting it
out. [
Figure 6.2
]
5. Remove the water filter sponge from
the water filter if necessary for cleaning.
[
Figure 6.3

Problem Possible Solution
Humidifier doesn’t turn on,
or turns o unexpectedly.
Plug the humidifier into a working outlet and turn it on.
Add purified or distilled water to the water tank.
Little or no mist comes out.
Turn the mist level to a higher setting.
Fill the water tank.
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 15). 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 17) 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 26).
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 15).
TROUBLESHOOTING
21
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 26).
Mist leaks from the base.
Make sure the water tank is properly in place
(see Getting Started, page 8).
White dust appears around
the humidifier.
We recommend using purified or distilled water to fill the humidifier.
Avoid using water with high mineral content, such as tap water.
Clean the humidifier (see Care & Maintenance, page 15).
Water visibly leaks from the
humidifier.
Avoid running the humidifier in a room with over 60% relative humidity.
Wipe any excess water o the top and bottom of the base.
Do not shake the humidifier.
