Dehumidifier WDH-416S
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:
After transport:
Since the unit uses refrigerant, improper transport can sometimes occur despite careful instructions on the carton.
For this reason, we ask you to leave it standing upright for at least
4 hours before using the unit for the first time, so that the refrigerant can settle properly in the unit.
In case of any problems:
We hope the device meets your expectations! If, despite the greatest possible care, there should ever be cause for
complaint, we ask you to contact us briefly, as we are very concerned about your satisfaction and would like to
clear up any misunderstanding.

On first operation:
As the internal piping comes into contact with moisture for the first time, it can take up to approx. 3 hours for the
first liquid to accumulate in the collection container, depending on the humidity.
Start-up time / delay:
To protect the compressor, the unit does not switch it on again immediately after it has stopped operating or there
has been an interruption in operation (e.g. emptying the condensation tank). The unit is initially in a so-called
"protection mode" for about 3 minutes, in which only the fan runs and the compressor does not switch on. The
green operating light also only switches on again after the protection/waiting time has elapsed.
Room humidity and dehumidification performance:
If you wish to check the room humidity and the associated dehumidification performance with your own humidity
meter (hygrometer), please avoid mounting this humidity meter on a wall, as this will falsify the true humidity
content of the room air. See also the explanations under Troubleshooting !!!

Directions for use:
1. Commissioning
1.1 Insert the power plug properly into the power outlet.
1.2.Check that the condensation tank is properly seated in the dehumidifier. (When using the dehumidifier for the
first time, it is possible that the "condensation tank full" light is illuminated. Simply pull the condensation tank
out briefly and then push it right back in again and you are ready to go! )
1.3 Switch on the device with the operating switch (on/off button). Now press the humidity setting button and set
your target humidity as desired. The target value "CNT" corresponds to continuous operation ! The value you
set must be below the current room humidity for the unit to dehumidify. If your value is above the current room
humidity, the fan runs for 3 minutes and the unit then switches off. If the room humidity rises above the set
value, the device automatically starts dehumidification operation again.
1.4 Use the air circulation adjustment button to select between low and high fan speed / air circulation.
1.5 If you want to activate/use the timer function (function for determining the remaining time or function for
specifying a start time), press the TIMER button.
Determining the remaining run time: Press the TIMER button during operation to select the desired remaining
run time of the dehumidifier. (A value between 1 - 24 hours can be selected). After this selected operating time
has elapsed, the device switches off automatically.
Determining a start time: When the dehumidifier is switched off, press the TIMER button to select the desired
start time. (A value between 1 - 24 hours can be selected). After this selected time has elapsed, the appliance
switches on automatically (with the last settings used, provided the mains plug has not been disconnected in
the meantime).
1.6 If you want to use the laundry drying mode, press the button to activate the laundry drying mode. In the laundry
drying mode, the air circulation is continuously set to high.dehumidified. The appliance operates in continuous
mode here. Exit the laundry drying mode by pressing
pressing the button again to activate the laundry drying mode.
1.7 In the air circulation mode ( air purification ) only the fan operates and no dehumidification takes place.
Start and stop this setting, by pressing the button to activate the
Air circulation mode (air purification).
2. Emptying the collection tank / When the "Condensation tank full" light is on
When the condensation tank is full, the signal light comes on and the dehumidifier then
automatically stops its dehumidification operation. Remove the condensation tank and empty
it. After you have pushed the condensation tank neatly back into the device, the
dehumidification operation starts again automatically.
3. Connecting a hose
3.1.You will need a ½ inch plastic hose.
3.2.Remove the condensation tank for a short time.

5.2 Cleaning the air filter
The air filter filters lint, hair and coarse dust. The air filter is coated with an antibacterial glaze to inhibit the
proliferation of bacteria. Furthermore, the air filter ensures that less dust is deposited on the cooling fins and thus
ensures higher efficiency.
- Always clean the filter when it can be assumed that the air intake is reduced by the dirty air filter !
- Then remove the air filter from its holder (the filter grid).
- It is best to clean the air filter carefully under lukewarm water or with a weakly adjusted (suction power)
vacuum cleaner.
- Reattach the air filter/strainer to the filter grille and reattach to the back of the unit - DONE.

Troubleshooting:
The unit does not dehumidify enough / Too little water accumulates in the condensation tank
Please remember that the primary objective is not to gain as much condensation water as possible, but to dry
and/or keep the room air or ceilings, walls and inventory dry !
Furthermore, remember that the dehumidifier can only remove moisture from the air and only indirectly from
materials. Depending on the condition of the ceilings, walls and fixtures, it can take several weeks until they have
released the stored moisture back into the air! For this reason, we also recommend that if you use your own
humidity meter (hygrometer), to place it as freely as possible and somewhat away from walls and ceilings, because
otherwise the determined humidity value of the room air is falsified!
As with all dehumidifiers, the dehumidification performance is decisively influenced by the following factors:
A) humidity content of the room air and B) heat/temperature in the room.
Therefore, for safety's sake, here is an excerpt from the dehumidification table at DAUERBETRIEB:
35 degrees and 80% r.h. = approx. 18 litres and at 90% r.H. = approx. 20 litres and at 60% r.H. = approx.
10 litres
30 degrees and 80% r.h. = approx. 16 litres and at 90% r.H. = approx. 18 litres and at 60% r.H. = approx.
8 litres
20 degrees and 80% r.H. = approx. 9 litres and at 90% r.H. = approx. 11 litres and at 60% r.H. = approx.
5 litres
15 degrees and 80% r.H. = approx. 7 litres and at 90% r.H. = approx. 8 litres and at 60% r.H. = approx.
3 litres
10 degrees and 80% r.h. = approx. 4 litres and at 90% r.H. = approx. 5 litres and at 60% r.H. = approx. 2 litres
5 degrees and 80% r.h. = approx. 3 litres and at 90% r.H. = approx. 4 litres and at 60% r.H. = approx. 1 litre
All data are approximate per day (fluctuation tolerance) with a measurement directly at the device input and of
course these values are only valid with constant temperature and moisture content!
The device rattles or makes running noises
Running noises are mostly caused by the air filter unit. We kindly ask you to remove the air filter once and check
whether the running noises are still present to the same extent ?
An unfavourable position of the dehumidifier is often the reason for higher running noises. Try changing the position
a little, as the running noises will then mostly disappear. Optimum and particularly quiet operation can be achieved
if the dehumidifier is placed on a piece of carpet, doormat or similar during operation! (Stone floors, tiles, laminate
or parquet, on the other hand, increase the operating noise of the dehumidifier! )
The device is leaking or water is leaking out
In this context, we would like to provide you with the following information:
A "leak" on your dehumidifier is actually impossible, unless the main frame is broken and of course something like
that can be ruled out without force.
If the water still leaks out, then the condensate probably comes from the "emergency drain", which is located
behind the collection tank at the very top right in a small triangular recess. The reason for this is that the normal
drain is prevented. This can have the following causes:
1. The most common cause is a slight soiling in the drip tray or the left drain (e.g. due to dead insects, dirt or
similar) and therefore the condensate cannot drain off normally. In this connection, please check the left drain
once or shake the unit once briefly in the upside-down position. Make sure that you then wait at least 4 hours
before switching the unit on again!
2. The device does not have a straight stand.
3. It may be that only a large piece of ice has detached from the cooling fins of your dehumidifier and this leads to
a short-term blockage. We therefore recommend that you disconnect the unit completely from the power supply
for a day and then the unit should no longer "leak".
