4.0.0 Placing the unit
The unit is usually placed in the wall by a window. This position makes the most of the
coanda effect, which circulates fresh air well into the room. This gives the air longer to mix
with the existing air in the room, avoiding drafts. The location of the supply grille and
extraction provide optimum circulation in the room.

7.0.0 Technical specifications
The airflow indicates the balanced air change in relation to motor voltage stated in m
3
/h.
The standard unit setting is max. (see table above). If forced operation is required, please
contact the dealer.
Noise level is stated in dB(A) in relation to air change, measured at a distance of 1 metre
from and 1,2 m below the supply air grille. For comparison, a whisper is equivalent to 30
dB(A), ordinary speech 60 dB(A) and urban traffic approx. 90 dB(A).
Temperature efficiency degree at the heat exchanger is stated in % and is the relationship
between the temperature differences achieved and the maximum achievable temperature
difference, i.e. the outdoor temperature minus supply temperature divided by the outdoor
temperature minus room temperature, converted to percent.
