Troubleshooting
The units are manufactured
using state-of-the-art production
methods and tested several times
to verify their correct function.
However, if a functional fault
should occur, the unit should first
be checked in accordance with the
following list.
The unit does not start:
■
Check the hygrostat’s setting
The set value must be lower
than the relative humidity in
the installation room!
■
Check the power supply and
the power fuse provided by the
customer
230V/1~/50 Hz
■
Check the power plug and the
cable for damage
■
Check the condensate tank’s fill
level and seating
The “Container full” indicator
light must not be illuminated!
■
Check that the microswitch
[MS] on the condensate
container is functioning
■
Check that the inlet and outlet
are free
Overheating!
■
Check the fuse on the control
board
5. Clean the air filter with
lukewarm water or a vacuum
cleaner.
6. Heavier contamination may be
remedied by rinsing the filter in
a lukewarm (max. 40 °C) soap
solution.
Finally, always rinse the filter
carefully with clear water and
allow to dry!
7. Also check the intake grill for
contamination and clean if
necessary.
8.
Before refitting grill and filter,
ensure that they are fully dry
and that no damage has been
sustained.
NOTE
Heavily contaminated or
damaged air filters must be
replaced with new parts.
Only original spare parts may
be used.
NOTE
Adjustment and maintenance
work may only be carried out
by authorised and qualified
technicians.
Filter cleaning
To prevent damage to the unit, it is
equipped with an intake grill with
integrated air filter.
In order to prevent power losses or
unit faults, the intake grill with
filter must be inspected as
required, but every 2 weeks at the
latest, and cleaned if necessary.
1. Use the hygrostat to switch the
unit off.
2. Remove the power plug from
the mains socket.
3. Reach into the recess [G],
push the intake grill backwards
slightly and pull it upwards and
out of the unit’s rear wall.
4. Remove the filter that is behind
the intake grill.
