Troubleshooting
This section helps you identifying the cause of an occurred problem and gives advices of how
to solve it.
If problems arise with the adsorption dryer please check the following points. Should the
fault not be located please contact your technical advisor.
Problem
Possible cause
Remedy
Adsorption dryer does not
work / no air current can be
felt at dry air outlet and at
regeneration air outlet / no
air noise can be heard
Adsorption dryer switched
off
Switch adsorption dryer on
using the On / Off switch
Power supply interrupted
Check power supply, power
cable, power outlet and
device fuse
The humidity set on the hy-
grostat has been reached.
The adsorption dryer will au-
tomatically re-start when the
set humidity is exceeded.
Air filter clogged
Change the air filter (see
Rotor drive defective / drive
belt torn
Entrust a specialised com-
pany with the repair of the
adsorption dryer
The desired humidity is not
achieved / the device does
not automatically switch off
although the hygrostat is
connected
The device is not sufficiently
dimensioned
Ask your specialised dealer
to calculate the capacity re-
quired for your application.
There is very much humidity
in the masonry or in the floor
The adsorption dryer will
need some time to remove
the water and achieve an ac-
ceptable value in the room.
The regeneration air has the
same temperature as the dry
air / the desired humidity is
not achieved.
Heater defective
Entrust a specialised com-
pany with the repair of the
adsorption dryer.
The drying performance of the adsorption dryer largely depends on the operating conditions.
Part of the air taken in by the adsorption dryer from the room is discharged from the room
with the regeneration air. As a result, negative pressure builds up in the room which causes
the corresponding amount of outside air to flow in.
The adsorption dryer can achieve very low humidity values in the dry air outlet (at intake
20 °C / 60% r.h. for example about 30 °C / 20% r.h.), but due to the outside air flowing in the
humidity in the complete room will never reach the low value of the dry air.
Danger of injury by electric shock and risk of material damage
• The device may only be repaired by trained specialised staff. Within the warranty period,
any work on the dehumidifier shall only be carried out by the manufacturer or persons
commissioned by the manufacturer. Any work carried out by unauthorised persons shall
lead to the forfeiture of all warranty claims!
Danger of cutting when reaching into inlet or outlet openings .
Danger of cut injuries at air inlet and outlet.
• Do not reach into the openings; carry the device exclusively by the handle.
