Sound levels
F2050 is usually placed next to a house wall, which gives a
directed sound distribution that has to be taken into consid-
eration. Accordingly, when setting up, you should always
attempt to select the side that faces the least sound-sens-
itive neighbouring area.
The sound pressure levels are further affected by walls,
bricks, differences in ground level, etc and should therefore
only be seen as guide values.
F2050 adjusts the fan speed depending on the ambient
temperature and evaporation temperature.
