It can also be fi xed to the ceiling using a threaded rod:
• Insert in the framework ceiling 4 threaded rods.
• Insert the rods through the holes
in the unit base (13 mm).
• Place the antivibration mounts,
insert a washer and turn the nuts
until the unit is well secured.
• If there is enough space between
the framework and the unit, a
rubber or neoprene plate can be
squeezed in.
• Check that the unit is perfectly
levelled.

Since it is an unit designed to work indoors with ducted supply and
return, both in the indoor and the outdoor circuits, the following aspects
need to be considered as well:
- Ensure that the location of the supply and return grilles does not
generate air recirculation.
- Check that there are no obstructions in the air supply and return grille
slats due to being tightly closed.
- If in the indoor/outdoor circuit the air return is not ducted, it is
necessary to foresee in the plenum formed by the ceiling, framework
and walls, adequately sized grids appropriate so that the circuit in
question aspires the return air.
Sound level
These units are designed to work with a low acoustic level. In any
case, the design of the installation the outer environment, the kind
of building for the noise transmitted in the air and the solid elements
for the vibration transmission must be taken into consideration for the
acoustic radiation.
If necessary, commission a study to an acoustic technician.
C) The sound pressure level of the unit, with the ducted return and
supply connections, measured at a distance of 5 metres, in open fi eld,
directivity at 2 and 1.5 metres from the ground is:
B) The sound power level in the indoor fan outlet to be taken into
account for the silencer calculation:
A) The sound power level in the outdoor fan outlet to be taken into
account for the silencer calculation:
Note: The sound pressure level depends on the installation conditions
and, as such, is only indicated as a guide.
