Aeraulic Connections; Return And Supply Ducts - Daikin UATYA-BBY1 Installation, Use And Maintenance Manual

5.6 Aeraulic connections

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 (for particular applications, consult our Technical Department).
The ducts connected to the appliance shall not contain any potential ignition source as defined by IEC
60335-2-40:2018.
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.
We reserve the right to make changes without any prior notice.
