This cleaning is without fail regularly required!
During construction site effort, after every effort or once a week!
No other maintenance work is required for the air dryer.
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
+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.
2)
The fan of the dehumdifier does not work
.
- The unit is in defrost mode. In this case the compressor still runs and the fan does
not run. The red neon in the operation panel lights up. 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.
-
Only at units with optional extra „ThermoLogic“
>>Thermostat switch off“<<
(= red neon in the operation panel):
The ambient temperature in that room is lower than +3°C or higher than +32°C.
The red neon lights up (see 5.3 / 5.4 / 5.5 „operation panel“). The unit will start
again when the temperature in that room has achieved normal conditions between
+3°C and +32°C.
-
Only at AD 740 / AD 750
>>water collecting bucket is full<< The red neon lights
up (see 5.3 / 5.4 / 5.5 „operation panel“). Empty the water bucket and put it back
into the unit. (see 5.7 „condensate outlet“)
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 units 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.
