9.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
+15°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 (refer to 5.5)
on an attainable value (e.g. approx. 50%r.F.), with it the dryer punctually may
switch off.
- The air filter (refer to 5.1 – Pos.7) 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.
2) The compressor of the dehumidifier does not work.
- The dryer has just being switched on (perhaps because the humidity increased).
In that case, only the fan starts first. After 3 Minutes the compressor will also start.
- The dryer is in defrost mode (refer to 5.8). In that case, the fan works and the
green neon in the operation panel (refer to 5.4 – Pos.3) lights up. After 10 Minutes
the dryer starts complete working again.
3) The complete dryer is out of operation. Fan and compressor does not run.
- Is the unit supplied with voltage? The green neon "operation" (refer to 5.4 – Pos1)
must light up. Check the main cable, an additional cable, the socket and the main
fuse.
- The humidity value adjusted at the hygrostat is achieved. The unit will start again
after exceeding the adjusted humidity.
- Water collecting bucket is full: The red neon lights up (refer to 5.4 – Pos. 4).
Empty the water bucket and put it back into the unit. (refer to 5.6)
4) Strong icing up at the evaporator.
- The ambient temperature is to low (< +15°C). Put the dryer into a room with min.
+15°C room temperature and wait until complete ice is defrosted. Switch on the
unit again (in that room with min. +15°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 +15°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.
