Air ducts connections
For units designed for installation indoors with ducted supply and
return in the outdoor circuit, it is advisable to have the following
recommendations:
- Curves in the fan discharge supply must be avoided. It is
recommendable to have a straight section of duct measuring
approximately 1 metre. If it is not possible, they must be as smooth
as possible, using indoor de
fl
ectors when the duct is of large
dimensions.
- When making the ducts, direction sharp changes must be avoided
since they can generate occasional pressure drops, which affect
the available pressure and the
fl
ow. The location of discharge
and aspiration grilles must be studied carefully to avoid the air
recirculation and the transmission and generation of noises to the
interior.
- No matter the type of ducts type to use, these must be insulated and
must not be composed of materials that propagate
fi
re nor expel toxic
gases in the event of a
fi
re. The internal surfaces must be smooth
and should not pollute the air that circulates within them. In any case,
the effective legislation about this issue must be respected.
- Flexible connections must be made between the ducts and the unit
that avoid the noise and vibration transmission.

Flexible connections
Optionally, these units can be sent with
fl
exible connections for supply
and return air.
In case of asking together for
fl
exible connections and damper for
condensation pressure control (optional for version STD), discharge
fl
exible ducts are attached to the above mentioned damper.
If it is removed the damper for installation on duct, it is necessary to
maintain the frame for reconnecting the
fl
exible connections.
