INSTALLATION INFORMATION
Mounting the acoustic sail on the secondary air cooling unit
1. Remove the protective film from the bottom of the secondary air cooling unit after mounting on the ceiling and before
installing the acoustic sail.
2. Remove the supplied hexagon nuts (4x) and plain washers (4x) on the fitting side (sheet metal side) of the acoustic sail
after opening the transport packaging.
3. Remove the acoustic sail carefully from the packaging.
4. Lift the acoustic sail (e.g. using a lifting device) and align it with the secondary air cooling unit as shown in the technical
drawing (PART II-4). The cut-out sections in the cover panel of the acoustic sail must be situated below the respective
openings of the fan and the supply air connector.
5. Insert the four M8 bolts of the acoustic sail into the slots in the frame profiles and the two hinges, then secure them with
plain washers and M8 nuts. The nuts must be tightened such that no air gap is visible between the secondary air cooling
unit and the acoustic sail.
nut and washer
In order to prevent soiling of the white covering material,
the acoustic sail must only be handled and touched at the
outer frame profile. Failure to observe this point can result
in damage to or soiling of the material.
6. The two hinges can be aligned and adjusted to reduce the size of the gap. The M8 nuts must be loosened slightly for this
purpose.
