Air that is too dry can cause or aggravate sinus and respiratory problems, lead to dry skin,
nose and throat and dry out plants and furniture.
Your humidifier is an effective device for diffusing water vapor in the surrounding air.
Humidity, which is expressed as Relative Humidity (HR), is the quantity of vapor present in the
air expressed as a percentage of the maximum quantity of vapor that the air can hold at the
same temperature without causing condensation.
Relative Humidity is measured with a hygrometer.

OPERATING PRINCIPLE

Your humidifier uses two complementary humidifying systems:

• A cold vapor system: a piezo disc that vibrates at an ultrasonic frequency to create tiny water
droplets.

• Heated mist system for anti-bacterial and turbo effects.
It can thus be used to automatically increase the level of humidity of the surrounding air and it also
has an electronic hygrometer for precise control of the Relative Humidity.

LOCATION

The use of a humidifier is particularly recommended in winter but the house should still be
regularly aired.
First, place the humidifier in the room requiring priority treatment. It is suitable for a room up
to 577 sq ft. (53,6m2).

Please read this instruction manual carefully as well as the instructions on safety and cleaning
before you start using the appliance. Please keep this instruction manual in a safe place.

device starts directly in AUTO mode.

SMART OPERATION MODES:

Selection of operating modes using button B. Select one of the three modes by repeatedly pressing
the button B.

1 - AUTO COMFORT MODE:

The appliance will automatically adapt the humidity level according to the room temperature for
optimal comfort at home.
In order to reach the optimal comfort in the room you are in, this setting takes in account the room
temperature and calculates the optimal humidity level.
When the humidity in the room is lower than the program, the appliance operates at maximum speed.
When the humidity in the room is reached, the appliance stops working and re-starts at maximum
speed as soon as the humidity in the room is lower than the program.
The humidity and the temperature in the room are measured every 60 seconds.

You can select the warm mist function with Auto comfort mode.

2 - CONTROL MODE:

• Humidity level: Button B for adjusting the required (target) humidity level;

Select the required humidity level by pressing button B several times.
The humidity level displayed is the required level that you have set (between 45% and 90% RH).
You can select the warm mist function with Control mode.

• Mist volume: Button C

Select the required mist volume by pressing button C several times. There are three speeds available.
You can adjust the mist volume in order to reach faster the required level of humidity.
PLEASE NOTE: This setting cannot be used for AUTO COMFORT mode.

3 - CONTINUOUS MODE:

Press the Button B, until the continuous mode, “Co” appears on the digital screen.
The appliance operates until reaching 90% RH (safety limit) or until the reservoir is empty. The mist is
permanently emitted and you can adjust the mist volume.
The appliance will stop working automatically when the humidity level of the room is over 90% RH and
it will re-start when the humidity level of the room measured is 80% RH.

WARNING: In the continuous operating mode, the humidity in the room can reach very high levels
that are not beneficial to health and can damage certain objects. The recommended optimal humidity
level is between 50 and 60% RH.

• Mist volume: Button C

Select the required mist volume by pressing button C several times. There are three speeds available.

ADDITIONAL FUNCTIONS:

• TIMER: Button D for programming the automatic stop of the appliance.

operating modes and allows you to increase the humidity output by 20%. As soon as the level of
humidity of the room is lower, the warm mist re-starts (on the screen the red pictogram appears).

* Removes up to 91% of Escherichia Coli and Staphylococcus Aureus bacteria representing most of the bacteria

• APPLIANCE(S) WITH REMOTE CONTROL (HU523x) :

The remote control uses 1 x 3V button cell (CR2025) which is not included.
Place the batteries in their compartment making sure that you put them in with the positive and
negative ends the right way round as shown in the battery compartment.

IMPORTANT: You are advised to switch off and unplug the appliance when not in use. When storing
the appliance for a longer period of time, please remove the batteries from the remote control.

• EMPTY TANK INDICATOR: red light N and sound indicator

If the water level is too low or if the water tank is removed, the three beeps are activated along with
the red pictogram (N) blinking on the screen. If the water tank is not filled or replaced after 15 minutes,
the appliance will stop automatically. Fill the tank and replace the water tank on the base, the appliance
will work normally.

MAINTENANCE

IMPORTANT: this type of appliance requires regular and thorough maintenance. Like for any
humidifiers with stagnant water, we recommend to give the appliance a complete clean once a
week (depending on use) to avoid bacteria proliferation.
You must always switch off and unplug your appliance before undertaking any maintenance on it.

Never put the product base under tap water because of risk of water entrance by air outlet.
It is important to clean the water tank, the vaporization area (around the piezo disc, the heating element
and the piezo disc.) and the air inlet grids located under the appliance regularly.
Never use detergents or scouring products for cleaning your appliance.
Never immerse the base of the appliance, the power cord or plug in water or any other liquid.
Regular cleaning of the piezo disc will avoid scaling. Do not use hard or abrasive utensils so as not to
damage the piezo disc. Only use the brush provided with the product.
We recommend to use cold boiled water or distilled water.

• Cleaning the tank:

1- Clean the tank and the tank stopper using soapy water and dry it with a soft dry rag.
2- To clean the inside of the tank, pour water into it and shake vigorously. Empty and dry with a soft

dry rag.

3- Make sure to pull out the water from appliance and dry it before you store it for a long period of time.

• Cleaning the vaporization compartment (arround the piezo disc 13), the heating element and the

piezo disc.

1- Remove the tank.
2- Add the powder from 2 bags provided with the device (2x10 grammes) to 0.158 Gal. (0.6 Liter) of
hot water. Stir until the water has completely dissolved.
3- Fill the vaporization compartment with this solution and wait for 1 hour to take effect.
4- Empty and remove the scale using the brush provided with the device.
5- Rinse out the whole of the compartment with fresh tap water (Important, make sure that no water
gets into the fan air outlet (16).

WARNING : we recommend to give the heating element and the piezo disc a complete clean as
soon as scaling sediment appeared on them to preserve same level of performances.
