a vacuum cleaner, equipped with a brush or
other soft attachment. Alternatively, blow
compressed air through the coil from the in-
side out, and brush with a soft bristle. Do not
use a wire brush. Do not impact or scrape the
coil with the vacuum tube or air nozzle.
• Before closing the fan door, turn the fan blade
in the position shown in picture 6, to avoid
that the door hits the fan.

be installed. If evacuation of refrigerant has to be
done, it shall be done in such a way that no refri-
gerant can escape to the environment.
