matically in case of overheat, e.g. the whole or partial obstruction of the wind outlet or
back net. In this case, unplug the appliance, wait about 30 minutes to cool it and remove

automatically. After a short cooling down phase (30 minutes), please set the desired
settings to start operating again.
