Aeraulic Connections; Return And Supply Ducts - Daikin UATYA-BBAY1 Manuel D'installation, D'utilisation Et D'entretien

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 return and delivery ducts may be connected to be fit for different directions.
Some units allow the selection of the duct direction at the time of installation; others require that this detail be
specified in the order.
Refer to our document "Rapid News" and/or to the selection software for correct identification of the required
guidelines.
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.
