Humidifier WDH-MG1
Dear Customer,
You have chosen a high-quality product. To ensure that you get a lot of enjoyment from this product, here are a few
more tips:
In case of problems
We hope that the unit meets your expectations! If, despite the greatest possible care, there should ever be cause
for complaint, please contact us briefly, as we are very concerned about your satisfaction and would like to clear up
any misunderstanding.
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 use any flavourings etc.

Functional description / control panel
On/Off button: As soon as the blue operating light lights up in the display, you can switch on the unit with
the On/Off button. After switching on, the individual setting symbols light up.
Steam strength/operating strength: With this button you can set your individual humidification strength.
The following options are available:
One green bar: > Very weak humidification performance
Two green bars: > Weak humidification performance
Three green bars: > Average humidification output
Four green bars: > High humidification performance
Five green bars: > Maximum humidification output
Target humidification key: Use this key to set your individual humidification target. The following options
are available:
L > Lowest target humidity value (below 25%) > Not recommended
25% / 30% / 35% / 40% / 45% / 50% / 55% / 60% / 65% / 70% / 75% / 80% / 85%
H > Highest target humidity value (over 85%) > not recommended
The unit humidifies until the set humidity is reached and then switches off automatically. If the humidity falls
below the set target value again, the unit switches on again automatically.
Note: The humidifier's humidity sensor sits under the unit (so as to be as far away as possible from the
unit's steam outlet). Nevertheless, the humidity sensor always gives only a tendency of the room humidity.
This is because, depending on the background, the displayed value may be lower or higher than the actual
room humidity. However, by varying the target humidity value, this circumstance can be compensated for !

Remote control
All functions and settings as described in the above symbols can also be operated/adjusted with the
supplied remote control.
A button cell CR2025 (3V) is required to operate the remote control.
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 flat 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. Take out the white water tank, fill it with
water and then put it back into the appliance.
Notes: > Always use only water with a temperature below 40°C !
Always use boiled and then cooled water. Excellent is also
distilled water to avoid calcification of your appliance !
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 at the main switch on the side
(see fig. right). The unit is now in standby mode.
2.3.Now press the On/Off button to start the humidification mode. Now the individual setting symbols
including the display of the current room humidity light up and the unit starts humidifying at the highest
humidification level by default.
2.4.Now you can still make your individual settings on the control panel (see key explanation in the function
description).

3. Cleaning
3.1 Preparation for cleaning
Please switch off the appliance first and disconnect the mains plug before cleaning
the humidifier.
Open the upper lid of the humidifier and first remove the white water tank and the
black steam nozzle shaft incl. steam nozzle.
Now unscrew the residual water drain (see illustration on the right), which is
located on the lower rear side, and empty the appliance completely of any residual
water.
Note: It is best to place the appliance in a sink to empty it, as up to one litre of
residual water can still run off !
3.2 Cleaning the housing and the wet area
Only use mild cleaning agents to clean your humidifier.
Rinse the white water tank carefully and wipe it from the outside with a damp cloth.
Next, clean the black steam nozzle shaft incl. the steam nozzle.
Now carefully clean the white water cup incl. the ultrasonic water vapour unit in the lower part of your machine.
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 water cup. These limescale deposits in the unit and especially
in the area of the evaporator and the water vapour unit can lead to impaired 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 water vapour unit itself is made of silver metal and has three approx. 2 cm large evaporators
(eyes) on the top.
a.) Add 5-10 drops of a suitable cleaning agent (e.g. Dimanin A* available in any pharmacy*) to the surface of
the vaporisers or also to the remaining area of the water cup 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 (see
illustration on the right).
Note: Never clean the evaporators with objects made of metal
or blunt material! This would damage the evaporators.
c.) Finally, rinse the evaporator / water cup well with clear water.
With the exception of the electrical control panel, all parts of the
humidifier can be wiped or cleaned with a soft damp cloth when the
unit is switched off.
Remove any water, clean the unit thoroughly and dry it well if you are not going to use the humidifier for a long
time.

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 especially the case in winter, as
the cold outside air then has only a low absolute humidity. Therefore, it should be re-humidified by a humidifier after
it has been warmed up to room temperature in order 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:
