10. Trouble shooting
Assign that dehumidifier a putative defect on, please, first check the following points.
If this should provide no relief, please contact your technical consultant.
1) The dehumidifier shows a bad or no drying capacity
- The humidity is lower than 40% r.h. or the temperature in that room is lower than
+3°C. The using of the dryer is uneconomical in the case of these conditions. It is
recommended to disconnect the dryer. Tipp: Put the built-in hygrostat on an
attainable value (e.g. approx. 50%r.F.), with it the dryer punctually may switch off.
- The air filter is soiled. The dryer does not receive air sufficiently. Clean the filter
and/or install a new one. A soiled air filter can in the long run lead to
disadvantages at the dryer. Tipp: Control the filter regularly. Do only use original
air filters!
2) The fan of the dehumidifier does not work, the compressor still turns.
- The unit is in defrost mode. In this case the compressor still runs and the fan does
not run. After some minutes, the unit will start with regular working
3) The complete dryer is out of operation. Fan and compressor does not run.
- Is the dryer switched on? The On-/Off-switch must be in position `I´ and must light
up.
- Is the unit supplied with voltage? The On/Off-switch must light up in Pos. `I´.
Check the main cable, an additional cable, the socket and the main fuse.
- The humidity value adjusted at the hygrostat is achieved. The dryer will start again
after exceeding the adjusted humidity.
- There is a fault at the condensate pumpe. In that case the red neon in the
operation panel (see Pt. 1.1) lights up. Check the pump and all cables. Let repair
the unit by an expert.
4) Strong icing up at the evaporator.
- Put the dryer into a room with min. +10°C room temperature and wait until
complete ice is defrosted. Switch on the unit again (in that room with min. +10°C)
and let work for approx 3 hours. If there is icing up again, please contact your
dealer. Otherwise make sure that the unit is only been used in rooms with more
than +3°C. Also the storage of the dehumidifier at inadmissible temperature
conditions can lead to damages / problems while immediate switch-on.
5) The humidity adjusted at the hygrostat does not become achieved and/or the
device does not switch off automatic.:
- Is the hygrostat adjusted on a value lower than 40 – 45% r.h.? Humidity values
with a minimum of 40 % - 45 % r.h. can be achieved with a condensation dryer.
Adjust the hygrostat to a reachable value.
- Is the unit with enough capacity for your application? The air changing, number of
the persons in the room and open water surfaces decide on the humidity burden
in the room. Let calculate the necessary capacity from your dealer
- Is there a lot of water in the walls or the floor? In that case the dryer needs some
time to remove that water and to achieve an acceptable humidity in that room.
