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".
