7.3 Piping connection
The device fittings have a nominal diameter of 160 mm. Rigid or flexible pipes can
be connected to the device inlets. Below is an illustration of each connection with a
specification also of the directions of origin and supply of the relative air flow (fig.9).
ATTENTION: For passivhaus compliant systems, it will be necessary to install silencers
on all 4 air vents.
7.4 Stale air supply toward outside
This inlet is used to expel stale air, which has already been treated in the heat
exchanger, to the outside. The duct to which the exhaust must be connected must be
thermally insulated (to avoid the formation of condensation inside or outside its parts),
and provided with devices to dampen any vibrations. If the exhaust takes place from the
roof, there must be a suitable device present to prevent the formation of condensation
and the entry of rainwater (fig.10).
7.5 Fresh air from outside
This inlet is used for the entry of fresh air from the outside. The relative duct
must be thermally insulated and provided with devices able to dampen any vibrations.
If air inlet occurs from the roof, the use of a suitable device is required to prevent the
formation of condensate and the entry of rain water. (fig. 11)
7.6 Stale air exhaust from room (extract)
This inlet is used to convey stale air extracted from inside the house into the device. The
duct must be thermally insulated. (fig. 12)
7.7 Fresh air supply to room
This inlet is used to pump fresh outside air, which has already been treated in the heat
exchanger, into the house (fig. 13)
