Possible cause
-
The compressor has stopped
automatically caused by a
too high temperature on the
condenser
Solution
• 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 lter in the duct
kit is dirty, clean if necessary.
• Check if the condenser coil
is dirty
• Check if the room tempera-
ture is higher than 36 °C. If the
room temperature is higher
than 36 °C, the unit must be
stopped
• Check that the duct
openings are not covered
Check the built-in or the exter-
nal hygrostat, 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.
