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 a
ff
ect 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 e
ff
ective 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.
