The appliance’s connecting spigots have a standard
diameter of 150 mm . Rigid or flexible ducts may be
connected to these inlet and outlet spigots. Each
connection is labelled to specify the direction of the air
flow, as per the following figures.
Stale air flow towards the outside (extract to
external)
(fig.14)
This outlet is used to expel the stale air outside once it
has been processed by the heat exchanger. The duct to
which the outlet is to be connected must be thermally
insulated (to avoid the formation of condensate on its
inside and outside parts), and equipped with devices to
dampen any vibration. If the terminal is on a roof it is
mandatory to use a suitable device designed to avoid
the formation of condensation and rain water
infiltrations.
Fresh air intake from the outside (supply from
external)
(fig.15)
This inlet is used to supply the air from outside; the duct
must be thermally insulated and provided with devices
capable of dampening any vibration. If the terminal is on
a roof it is mandatory to use a suitable device designed
to avoid the formation of condensation and rain water
infiltrations.
Stale air flow extractor from the home (extract from
internal)
(fig.16)
This inlet is used to introduce the air extracted from
within the house into the appliance. The duct requires
thermal insulation.
Clear air inlet into the home
(supply to internal)
(fig.17)
This outlet is used to introduce external air into the
home, following treatment in the heat exchanger. In
order to guarantee the optimum level of acoustic
comfort, the silencer provided must be fixed to this
outlet.
Connection of the condensation draining tube
The connection point for this tube is located on the
underside of the appliance. The condensation drainage
can be achieved by connecting the siphon supplied
(installation with Prometeo in horizontal position:
fig.18A, installation with Prometeo in vertical position:
fig.18B).
WARNING: don’t install the siphon in orizontal
position.
The condensation drainage can also be routed to the
home drainage system.
