the fault not be located please contact your technical advisor.

Danger of injury by electric shock and risk of material
damage

The air dehumidifier 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!
Problem Possible cause Remedy
Air dehumidifier
shows poor or no
humidification
performance.
The ambient humidity is
lower than 40% r. h. or
the ambient temperature
is less than +3 °C. Under
these conditions
operation of the air
dehumidifier is
uneconomical.
Switch the air dehumidifier off.
Tip: set the hygrostat to an
achievable value
(e.g. to about 50% r. h.) to ensure
that the dehumidifier will switch
off in time in respect of the
ambient humidity.
The air filter is severely
soiled. The air flow is
insufficient. In the long
run, soiled filters can
cause damage to the air
dehumidifier.
Clean or, if required, replace the
filter.
Tip: perform maintenance as
described in chapter 7 at regular
intervals! Use only original
AERIAL air filters.
Compressor and/or fan
motor are/is defective.
