Troubleshooting
The unit is icing up.
In cold temperatures or long periods of continuous operation, the unit may freeze up despite the defrost sensor. In
this case, we recommend that you manually defrost the unit by switching it off and warming the room slightly.
The unit does not dehumidify enough.
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 building dryer can only remove moisture from the air and only indirectly from
materials (screed/plaster). Depending on the condition of the ceilings, walls and fixtures, it can take several weeks
before they release the stored moisture back into the air! For this reason, we also recommend that if you use your
own humidity meter (hygrometer), you place it as freely as possible and somewhat away from walls and ceilings,
because otherwise the determined humidity value of the room air will be falsified!!!
As with all building dryers, the dehumidification performance is decisively influenced by the following factors:
A) Humidity content of the room air and B) Heat/temperature in the room.
For safety's sake, here is an approximate dehumidification table for DURABLE OPERATION:
35 degrees and 90% RH = approx. 50 litres (optimum or maximum capacity).
30 degrees and 80% r.h. = approx. 42 litres and at 60% r.h. = approx. 21 litres
20 degrees and 80% r.h. = approx. 21 litres and at 60% r.h. = approx. 12 litres
15 degrees and 80% r.h. = approx. 15 litres and at 60% r.h. = approx. 8 litres
10 degrees and 80% r.h. = approx. 8 litres and at 60% r.h. = approx. 6 litres
All figures are approximate per day (fluctuation tolerance) when measured directly at the unit inlet and of course
these values only apply if the temperature and moisture content remain constant!
