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
+10°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. 60%r.F. in swimming pool rooms), with it the dryer
punctually may switch off.
- The heat exchangers are soiled. Not enough air flows through the dryer. Tipp:
Lead regularly maintenance as described in point 8!
2) The compressor of the dehumidifier does not work.
- The unit is in defrost mode. In this case the fan still runs and the compressor does
not run. After some minutes, the unit will start with regular working.(see 6.8)
- The ambient temperature in that room is lower than +3°C or higher than +32°C.
The unit will start again when the temperature in that room has achieved normal
conditions between +3°C and +32°C (see 6.9).
3) The complete dryer is out of operation. Fan and compressor does not run.
- Is the unit supplied with voltage? Check the main cable and the main fuse.
- The humidity value adjusted at the hygrostat is achieved. The dryer will start again
after exceeding the adjusted humidity.(see 6.7)
4) 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. (in swimming halls for exa,ple 60% r.h.)
- Is the unit with enough capacity for your application? The ambient temperature,
the water temperature, water movement and the open water surfaces decide
among other things on the dampness load in the area. 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
5) Water runs beside the dryer:
- Make sure that the dryer stands accurately straight on all axles (spirit level!)
- Make sure that the drain hose is surely fastened to hose connector.
- Make sure the drain hose is shifted away from the unit with enough slope.
- Examine whether the drain hose is free from the inside. In the course of the time it
can be blocked by algae.
- Make sure that the hose end is not in the water
