Possible cause
Check the external fuses
Check the power supply to the unit
If the unit does not start again after 45
minutes, check the following:
Check that the fan(s) is running
Check if the filter (CDF-T: in the duct
kit) is dirty
Check if the evaporator and the con-
denser coil is dirty
Check if the room temperature is
higher than 30 °C. If the room tem-
perature is higher than 30 °C, the unit
must be stopped
Check that the front cover panel
(CDF)/duct openings (CDF-T) are not
covered
Wait till the temperature has increased to
more than 3 °C
Check the built-in or the external hygro-
stat, if any, by setting it to a low relative
humidity, e.g. 10 – 20 %RH.
If the unit still does not start, check the
built-in or external hygrostat for defects
