During the first operation:
As the internal pipelines come into contact with moisture for the first time, it can take a few
hours for the first liquid to accumulate in the collection container, depending on the
humidity.
Room humidity and dehumidification performance:
If you want to check the room humidity and the associated dehumidification performance
with your own humidity meter (hygrometer), please avoid attaching this humidity meter to a
wall, as this will falsify the true humidity content of the room air. See also the explanations
under Troubleshooting !!!
Important safety instructions:
- Supervise the dehumidifier when children are near the appliance !
- Watch out for electricity, never walk into or insert objects into the appliance !
- Do not block the exhaust air fins of the unit and please ensure sufficient
space/clearance at and around the fan !
- Ensure that there is sufficient air supply to the unit, otherwise it can lead to a reduction
in performance and, in the worst case, to overheating !
- Only qualified personnel or electricians are allowed to open the unit !
- Make sure that no moisture gets to the electrics of the unit !
- Only use the recommended voltage for operating the unit !
- Make sure that the power cable is unfolded (untied) before connecting it to the socket !
- Make sure that the plug is cleanly and properly connected to the socket before using
the appliance !
- Never reach near the plug or socket with wet hands !
- Do not repair defective or damaged cables on the unit yourself, you could get a severe
electric shock !
- Make sure that highly flammable substances (e.g. gases/oils etc.) are never in the
vicinity of the unit !
- If you are not going to use the unit for a long time, switch it off and disconnect the
mains plug !
Please switch off the unit immediately and disconnect it from the
mains/power supply if anything seems to be wrong !!! In this case, please
contact a specialist and do not attempt to repair the unit yourself !!!

Functional description:
The intelligent mini dehumidifier WDH-898MD uses a Peltier condensation technology
(compressor-free Peltier principle without refrigerant). This technology has the great
advantage of making the device small, quiet and light. Thus, this mini dehumidifier can also
be used well in very small rooms, chambers and cupboards etc. !
Instructions for use:
1. Commissioning
1.1. Connect the power supply unit included in the scope of delivery properly to the
dehumidifier. Make sure that the cable is completely unfolded. Then insert the mains
plug properly into the socket.
1.2. Switch on the unit using the rear on/off switch. (see illustration on
the right).
1.3. Check that the condensation tank is properly seated in the
dehumidifier. (When using the dehumidifier for the first time, the "condensation tank
full" light may come on. Simply pull the condensation tank out briefly and then push it
right back in and you are ready to go).

1.4. Now press the arrow key (down ↓) below the front humidity display to set your target
humidity value. After the first press, the humidity display starts flashing. You can now
select your target humidity value in steps of 5% each (between 40% and 80%) by
repeatedly pressing the respective arrow key (up ↑ / down ↓). The target value of 40%
humidity usually corresponds to continuous operation. After approx. 10 seconds
without pressing the arrow key again, the humidity display stops flashing automatically
and the current ambient humidity value is displayed.
1.5. The front green operating light indicates that dehumidification is in progress.
2. Emptying the collection tank / When the "Condensation tank full" light (yellow)
is on
When the condensation tank is full (after approx. 1.7 litres of tank capacity), the front
yellow signal light lights up and the dehumidifier then automatically stops its
dehumidification operation. Remove the condensation tank and then the condensation
water drain plug. Now you can pour off/empty the accumulated condensate. After you
have pushed the condensation tank neatly back into the unit, the dehumidification
operation starts again automatically.
3. Other operating instructions
3.1.Do not disconnect the mains plug by pulling on the
power cable !
3.2.Do not use insect, oil or paint spray etc. near the
dehumidifier. This may cause damage to the unit or even
fire !
3.3.Do not place the appliance on sloping or uneven ground
!
3.4.Do not expose the power supply unit to direct moisture
or steam. For example, do not place the power supply
unit on a damp surface and ensure that there is
sufficient air around the power supply unit so that it
can dissipate its heat properly!
3.5.For effective and economical dehumidification
operation, please close all doors and windows in the
room where the dehumidifier is located !
3.6.Always hold and transport the unit in its proper and
upright position !

Troubleshooting
The unit does not dehumidify enough / Too little water collects in the condensation tank
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.
Please remember that the primary aim is not to gain as much condensation water as
possible, but to dry and/or keep dry the room air or ceilings, walls and inventory !
Furthermore, bear in mind 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 may take several weeks for the stored moisture to be released back into the air! For this
reason, we also recommend that if you use your own humidity meter (hygrometer), it
should be installed as freely as possible and should be placed somewhat away from walls
and ceilings, because otherwise the determined humidity value of the room air will be
falsified !!!
