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
indicator light should illuminate
■
Check power supply
220-240 V/1~/50 Hz
■
Check the power plug and
the 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
in the 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 air humidity, at least
40 % RH is required
■
Check the setting of
the humidity switch, set a lower
humidity value if necessary
■
Check the dust filter for
contamination and clean or
replace if necessary
■
Check the evaporator
and condenser fins for
contamination and clean if
necessary
■
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
CAUTION
Work on the refrigerant
system and on the electrical
equipment must only be
conducted by a specially
authorised specialist!
CAUTION
An electrical safety check must
be carried out in accordance
with VDE 0701 after any work
on the units.
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, contact an
authorised specialist.
