The first farm
As the inner units come into contact with water for the first time, there may be a slight
odour at the beginning. This initial smell disappears after a very short time (1-2 days).
Use only clear and clean (or distilled) water below 40°C to fill the humidifier, and do not
add any flavourings etc. to the water.
Functional description
The WDH-SK6630 ultrasonic humidifier uses ultrasonic high-frequency oscillation to
atomise the water into the smallest water vapour particles of approx. 1-5 µm (thousandths
of a millimetre) !!! A fan system then ensures that this ultra-fine water vapour is evenly
released into the room air until it has reached the desired humidity.
Important safety instructions
Only use the recommended voltage for operating the humidifier !
Supervise the humidifier when children are near the appliance !
Watch out for electricity, never walk into or insert objects into the appliance !

Instructions for use
1. Before use
Carefully remove the humidifier from its packaging box and remove all protective
packaging. Place the humidifier on a firm, level surface that provides sufficient space
for the unit and the user. Give the humidifier about half an hour (to adjust to the room
climate) before operating it for the first time.
2. Commissioning
2.1 Open the lid of your humidifier and fill the water tank with
clean, clear water.
Notes:
Always use only water with a temperature below 40°C !
Always use boiled and then cooled water. Distilled water is also excellent for
preventing calcification of your appliance.
avoid !
Only fill the water tank to the maximum quantity indicated and do not pour the water
directly into the steam shaft, this may cause the unit to stop operating automatically.
(see fig. below).
Wait briefly for a minute so that the water can distribute well in the lower part of the
humidifier.

2.2. Insert the mains plug of the unit into a socket and switch on the unit by pressing the
operating switch. Now set the desired humidification output using the operating switch.
In addition, you can activate the built-in LED lighting with the help of the LED button.
2.3. If desired, the aroma compartment can be used to distribute pleasant fragrances in the
room. To do this, remove the aroma compartment, which is located on the back of the
unit, and drip a few drops of your desired aroma onto the cotton pad (see illustration
below). Then push the aroma compartment back into the unit and start the
humidification mode.
Note: We recommend that you always use only 100% essential oil !
3. Cleaning & Storage
3.1 Preparation for cleaning
Please switch off the appliance first and disconnect the
mains plug before cleaning the humidifier.
Remove the lid of the humidifier and empty the unit
completely of any residual water. To do this, please use the
small opening at the upper edge of the water tank (see fig.
right).
Note: It is best to place the appliance in a sink to empty it.

3.2 Cleaning the housing and the wet area
Only use mild cleaning agents to clean your humidifier.
Rinse the water tank carefully and wipe it from the outside with a damp cloth.
Now carefully clean the round black ultrasonic water
steam unit in the lower part of your machine. To do this,
first remove the steam shaft by turning it slightly to the left
to release it from the water tank (see fig. right).
Notes: In the case of hard water (the tap water contains
too much calcium and magnesium), limescale deposits
can occur in the humidifier and especially in the area of
the evaporator and the water vapour unit and these can
lead to impairment of the functioning. We therefore recommend that you
Clean the evaporator and the ultrasonic water vapour unit every week.
Change the water in the water tank regularly to keep it fresh.
The ultrasonic evaporator is located at the bottom of the water tank (in the lower part
of the humidifier). You can see it very well by removing the steam shaft. The
evaporator itself is round, has a diameter of approx. 4 cm and is made of dark
ceramic.
Clean the evaporator as follows:
a.) Add 5-10 drops of a suitable cleaning agent (e.g. Dimanin A* available at any
pharmacy*) to the surface of the vaporiser or also to the rest of the lower area of
the water tank and wait a few minutes.
b.) Then carefully wipe off any flakes of dirt (limescale) from the surfaces with a soft
sponge or the enclosed brush.
Note: Never clean the vaporiser with objects made of metal or blunt material! This
would damage the vaporiser.
c.) Finally, rinse the vaporiser / water cup well with clear water and refit the steam
shaft.

3.3 Storage
Remove all water, clean the unit thoroughly and dry it well if you are not going to use
the humidifier for a long time. (Allow the appliance to dry out completely and please
remove all water residues).
We recommend that you store the dried out and cleaned unit in the original box when
not in use.

Other
Humidifier for a better climate and for the benefit of health
Especially during the heating season, the relative humidity often falls below the
recommended range for living and working spaces. This has an unfavourable effect on the
well-being and health of people and animals and can also promote diseases of the
respiratory system if the indoor air is permanently very dry. A too dry climate can also be
harmful for inventory and plants. This effect can be counteracted with our humidifier.
In the field of human medicine, a balanced humidity of the ambient air is recommended.
However, especially in closed, poorly ventilated and well-heated rooms, such values are
often fallen short of, which can lead to reduced respiratory performance and impairment of
the skin or mucous membranes.
This is particularly the case in winter, as the cold outside air then only has a low absolute
humidity. Therefore, after heating to room temperature, it should be humidified by a
humidifier to prevent the relative humidity from dropping too much.
In very cold regions or at cold times of the year or at night, the human organism often
shows an increased fluid consumption, although the opposite should rather be assumed
due to the lack of fluid loss through sweating. This is due to the humidification of the dry
inhaled air and the associated loss of water. If the cold outside air is heated during
inhalation, its water vapour capacity increases and thus also lowers the relative humidity.
In contrast, the saturation deficit increases and the tendency of the liquid lung tissue water
to change into the gaseous aggregate state increases. In summer or when the ambient air
is warm, the inhaled air is hardly warmed up any further and therefore retains its usually
high relative humidity. If the additional water losses through sweating are not too great
here, the body's water requirement is therefore higher in cold ambient conditions.
Increased humidity is beneficial for breathing, as oxygen then reaches the bloodstream
more easily via the alveoli. The skin needs a high level of humidity in order not to dry out,
as this is closely linked to skin moisture. Mucous membranes are particularly susceptible to
drying out, as they have little protection against evaporation and depend on their high
humidity to maintain their functions. Thus, low humidity of the nasal mucosa can result in
an increased incidence of nosebleeds. In general, the skin's immune defence is weakened
(increased risk of catching a cold) and its ability to exchange substances is reduced, which
particularly affects the oral mucosa. Low humidity also increases the susceptibility to skin
irritations or redness or even skin inflammations. Source: www.wikipedia.de
