The recommended distance between L Split and the
building wall should be at least 15 cm. Free space
above L Split should be at least 100 cm. However, the
free space from the front must be 100 cm for future
servicing.
Please bear in mind that the L Split unit is normally
placed against a building wall, which causes direct
sound propagation. Therefore, always try to find a lo-
cation that is out of the way, in an area that will cause

the least disturbance for neighbours. The sound level
may be affected by walls, bricks, differences in ground
level, etc., therefore the values given should only be
considered as suggested levels.
In order to reduce the noise level, avoid direct air out-
let to places that are particularly sensitive to excessive
sound levels. An action that can be taken is, for ex-
ample, creating acoustic boards so that the noise is
less inconvenient. Sound propagation is affected by
phenomena such as: source directivity, absorption by
the atmosphere, influence of the ground, surface re-
flection, shielding by obstacles.
