Air ducts connections
For units designed for installation indoors with ducted outlet and
return in the outdoor circuit, it is advisable to have the following
recommendations:
- Curves in the fan discharge outlet(s) must be avoided. It is recom-
mendable 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 defl 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 recircula-
tion 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.
Attention: In models with double air volume (2 circuits) are required
two separate air ducts.
Optionally, CIATCooler units can be sent with fl exible connections
for outlet and return air.
 Flexible connections
Optionally, CIATCooler units can be sent with fl exible connections for
outlet and return air.
The dimensions of the ducts can be referred to in the technical brochure
for these units.

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 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.

(*) The damper incorporates a frame (60 mm width) to fi t the damper
to the fan(s) outlet. Without fl exible connections this frame may be
removed for duct installation.
Models 640 to 960 (STD version) and 640 to 720 (HEE version) feature
2 fl exible ducts both in discharge and return air.
