Installation Area; Sound Pressure Levels - Alpha-InnoTec HT 6Split Installation And Operating Manual

Installation area

The recommended distance between LSplit and the
house wall must be at least 15 cm. Clearance above
LSplit should be at least 100 cm. However, free space
in front must be 100 cm for future servicing

Sound pressure levels

The LSplit is usually placed next to a house wall, which
gives a directed sound distribution that should be con-
sidered. Accordingly, you should always attempt to
find a placement on the side that faces the least sound

sensitive neighbouring area. The sound pressure lev-
els are further affected by walls, bricks, differences in
ground level, etc and should therefore only be seen as
guide values.
In order to reduce the noise level, avoid direct direct-
ing of the air outlet to places particularly sensitive to
excessive sound emission. The action that can be tak-
en is, for example, making acoustic screens so that
the noise is less onerous. The propagation of sound
is influenced by, among others, such as: source direc-
tionality, absorption by atmosphere, ground effect, re-
flection from the surface, shielding through obstacles.
