5.6 Aeraulic connections

5.6.1

Return and supply ducts

The units have provision for various connections of both the return duct and the supply duct.
To identify these, refer to the dimensional drawing present in the documentation of the unit.
For the connection, the closing panels with which the unit was shipped must be removed.
If the supply is downward, the panel on the bottom of the unit must be removed
The ducting must be suitably sized so as not to generate unforeseen concentrated and/or distributed head losses
that can cause drops in the handled air flow rate below the design flow rate. The head losses in the ducting must not
exceed the available pressure provided by the fans.
5.6.2

Connection of the ducts

Correct installation of the channels should comply with the following recommendations:
- the size of the ducting must be at least the size of the return inlet and supply outlet on the unit. It is preferable to
enlarge the ducts near the machine made in accordance with the rules of good practice;
- always seal the joints so as to prevent air escaping from the channels.
We reserve the right to make changes without any prior notice.
