cleaner from inside to outside. With the same vacuum
cleaner, remove the dust from inside the fan compartment
and the fan blades. Avoid any damage to the blades which
may cause future vibrations and noise.
Replace the unit cover and tighten the screws.
If necessary, proceed as follows for
more careful cleaning of the coil:
Switch the mains supply OFF.
