Tefal HD402X Aqua Boost

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 into the surrounding air. Humidity, which is expressed as Relative Humidity (RH), 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 mist system: a piezo disc that vibrates at an ultrasonic frequency to create tiny water droplets.
  • Heated mist system for anti-bacterial and turbo effects.
    The humidifier 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).

  5. Fill the water tank through the top filler of the lid
    PLEASE NOTE: We advise you to use slightly hard water to avoid the appearance of white dust; you can use tap water, bottled water, distilled water or boiled water.
    If you live in a hard water area, use clean, cool bottled water or distilled water. Please remember that the tank must always be filled with cold water.
    WARNING: Never insert water into the piezo area!

  6. Place the appliance on a flat surface and plug it.

  7. Adjust the nozzle so that the steam is not directed at an obstacle, which could adversely affect the humidity regulation.

  8. Press on the on/off button. The clean alert will automatically blink. Hold the on/off button for 2 seconds to reset the appliance.

  9. After filling the water tank, the appliance can take 2 to 3 minutes before starting outputting mist. The device starts directly in AUTO COMFORT mode.

HOW THE APPLIANCE OPERATES

”ON/STANDBY”:
switch on / standby (stop); button A.
Press button (A) to start the appliance or to put it on standby. The digital screen lights up and the device starts directly in AUTO COMFORT mode.

MIST VOLUME LEVEL: Button C
Select the required mist volume level by pressing button C several times. There are six levels available (three levels of cold mist/three levels of warm mist).
You can adjust the mist volume in order to reach faster the required level of humidity.
Warm mist option (anti-bacterial and turbo effects)
When pressing the button C, the mist volume level will increase as follows: Level 1 cold > Level 2 cold Level 3 cold > Level 1 warm > Level 2 warm > Level 3 warm > Back to level 1 cold.
On the screen, the mist volume level icon is either displayed in white (cold mist) or in red (warm mist). After 10 minutes of use, the mist becomes warm.
After 30 minutes of use in the warm mist position, the anti-bacterial action starts and allows you to fight the growth of germs* in the water base of the device. This function also comes as an extra to the other operating modes and allows you to increase the performance level. 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 99,9% of Escherichia Coli and Staphylococcus Aureus bacteria representing most of the bacteria known to exist after 30 minutes of use on warm mist position – under normal conditions of use – tests carried out by an independent laboratory.
    This appliance has 3 operating modes (AUTO COMFORT MODE, MANUAL MODE, CONTINUOUS MODE) as well as various additional functions.

    1. AUTO COMFORT MODE:
      Selection of the AUTO COMFORT MODE by pressing button E.
      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, this setting takes into account the room temperature and calculates the optimal humidity level. When the humidity in the room is reached, the appliance stops working and re-starts as soon as the humidity in the room is lower than the program. The humidity in the room is measured every 60 seconds.Temperature| ≤19 °C| 20-21°C| 22-23°C| 24-25°C| 26-27°C| 28-29°C| 30-32°C| 33-36°C| ≥37°C
      ---|---|---|---|---|---|---|---|---|---
      Humidity target| 65%| 60%| 55%| 50%| 45%| 40%| 35%| 30%| 25%

    2. MANUAL MODE:
      You can shift to the manual mode by pressing the button D
      Humidity level: Press button D for adjusting the required (target) humidity level;
      Select the required humidity level by pressing button D several times.
      The humidity level displayed is the required level that you have set (between 40% and 80% RH). You can select the warm mist function with manual mode.

    3. CONTINUOUS MODE :
      Press the Button D, until the continuous mode, “Co” appears on the digital screen.
      The appliance operates until reaching 90% RH (safety limit) or until the tank 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.

WARNING: In the continuous operating mode and manual 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.

ADDITIONAL FUNCTIONS:

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 every three days (depending on use) to avoid bacteria proliferation.
You must always switch off and unplug your appliance before undertaking any maintenance on it.

When the appliance needs cleaning, the CLEAN icon will light up with one bip sound on the screen. After the appliance is cleaned and placed in a correct position, reset the clean alert by pushing the on/off button during 2 seconds.
The alert will activate every time the product is plugged-in and every three days to remind the user the necessity of changing the water within the tank as per the European norm. Never immerse the product under tap water because of the risk of water entrance by the air outlet. It is important to clean the water tank, the vaporization area, and the air inlet grids located under the appliance regularly. Never use detergents or scouring products to clean your appliance. Never immerse the appliance, the plug, or the power cord in water or any other liquid. We recommend to use cold boiled water or distilled water.

  • Cleaning the tank:
  1. Clean the tank using soapy water and dry it with a soft dry rag.
  2. Make sure to pull out the water from the appliance, and dry it before you store it for a long periods of time.
    IMPORTANT: Empty the water inside the product by following the indications on the appliance (empty it on the right side). Never put water in the piezo tank. Don’t put water in the air oultet of the piezo.
  • Cleaning the vaporization compartment (around the piezo disc 13), the heating element, and the piezo disc.
    Rinse regularly (every 3 days) the water base with fresh water and dry it with a soft dry rag.
    IMPORTANT: make sure that no water gets into the fan air outlet (16).
    Regular cleaning of the piezo disc and heating element will avoid scaling. Do not use hard or abrasive utensils, only use soft materials with the device.
    In case of scaling appearance, please refer to the paragraph “SCALE CLEANING AND ANTISCALE CARTRIDGE”.

WARNING: We recommend giving the heating element and the piezo disc a complete clean as soon as scaling sediment appeared on them to preserve same level of performance.
TO AVOID ANY DAMAGE TO YOUR PRODUCT, PLEASE PROPERLY FOLLOW THE CLEANING INSTRUCTIONS, ESPECIALLY NOT LETTING WATER INTO THE FAN AIR OUTLET.Tefal-
