The surface of the
device is very hot. It is normal for the device to be hot when it operates, the
maximum surface temperature is limited in accordance with the
NF Electricity standard. However, if you feel that your device is
always too hot, check that the power is suitable for the surface
area of your room (we recommend an average of 100 W/m2
for a ceiling height of 2.50 m or 40W/m3) and that the device is
not placed in a draught that could interfere with its temperature
regulation.
Traces of dirt appear
on the wall around
the device. In a polluted environment, dirt can appear on the device’s air
outlets or on the wall. This phenomenon is associated with the
poor quality of the ambient air (smoke from cigarettes, candles,
incense, fireplaces, etc.). In this case, we recommend checking that
the room is properly ventilated (ventilation, air inlet, etc.).
