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 setting
of the operating switch.
The green control lamp should
illuminate
■ Check mains connection
230V/1~/50 Hz
■ Check mains plug and cable for
damage
■ Check the customer-provided
mains protection.
Minimum protection 10A
■ Check the level and correct
positioning of the condensate
container.
The front sealing flap must
be fully closed and locked
■ Check the function
of the microswitch
■ Check the setting
of the humidity switch
(accessories).
The pre-set value must be
lower than the relative humidity
inthe room.
■ Check the humidity switch
adapter for damage and correct
positioning
The unit runs but does not
form any condensate
■ Check the room temperature.
The operating range of the unit
is between 3°C and 32°C
■ Check the humidity of the air,
min. 40% RH required
■ Check the setting ofthe humidity
switch, set a lower humidity
value if necessary
■ Check the dust filter
forcontamination and clean
orreplace if necessary
■ Check the evaporator
and condenser fins for
contamination and clean
ifnecessary
■ Check the evaporator for ice
or rime formation If ice has
formed, check the functionality
of the automatic defrost
and the temperature sensor
■ Check whether or not
the evaporator temperature
is below room temperature
If this is not the case, check
the automatic defrost or room
temperature
The unit does not start
■ Check whether or not
the condensate container
is inserted correctly and that
the front sealing flap is locked
■ Check whether or not mains
power is available
4. Clean the condenser fins
by blowing, with suction
or using a smooth brush.
5. Exercise extreme caution when
cleaning the condenser. The fine
aluminium fins bend very easily.
6. Never subject to sharp jets
of water (high-pressure
cleaners).
7. Clean the evaporator fins, for
example with a lukewarm soap
solution (or similar).
8. Rinse with clean water
to remove any remaining soap.
9. Clean the internal surfaces
of the entire unit as well
as the fan blade.
10. Once cleaning has been
completed, the unit should
be dried with care.
Take particular care with
electrical components!
11. Re-install all dismantled
components in reverse order.
12. Carry out a unit function check
and electrical safety check.
NOTE
If the unit fails to function
correctly after the checks have
been carried out, an authorised
specialist must be informed.
ATTENTION
Work on the refrigerant
system and on the electrical
equipment must only
be conducted by a specially-
authorised specialist.
!
ATTENTION
An electrical safety check must
be carried out in accordance
with VDE 0701 after any work
on the units.
