15 AVAILABLE HEAD PRESSURE OF THE UNIT WITH INTEGRATED CIRCULATOR
We reporte below the Head pressure-Water flow characteristic curves without head losses of the hydronic kit (which is composed
of the components describe in the Paragraph 5.10) at the maximum speed of the circulator. The optimal operating point is
indicated on each curve under the specified conditions at the apex (1) p. 23. The plant system must be designed so as to ensure
the nominal water flow rate corresponding to the operating points indicated below.
For nominal points of LT version, please refer to water flow rates that are reported in the table on Paragraph 0.
