Aktobis WDH-500AH Manual
Allow the air filter screen to dry and then put it back into its holder on the inside of the front fairing from above.
Then push the retaining rods back through the outer and inner holes of the metal frame/front panel from above.
Now check the cooling fins and clean them with a soft hand brush or a hoover if necessary.
Finally, insert the front cover with the integrated air filter screen back into the holder of the building dryer from
above and close/fasten it to the unit with a slight tug. DONE !!!
7. Other notes
Do not expose the compressor to temperatures above 45°C. Please do not do this even if the unit is not switched
on/connected. This could damage the compressor !
The exhaust air of the building dryer is 2°C - 3°C warmer than the supply air (room temperature). This can lead to
greatly increased room temperatures in smaller and well-insulated rooms, this is quite normal.
For an effective and economical dehumidification operation, please close all doors and windows in the operating
room of the building dryer, if possible !

Troubleshooting

The unit is icing up.
At cold temperatures or during 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 then only operate it
with a target humidity value of 60% r.l. for the time being, or warm up the room a little. The target humidity value
can then be gradually lowered each day (e.g. 50%, then 40%, etc.).
The unit does not dehumidify enough.
Please remember that the primary objective is not to extract 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 extract 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 !!!
