TABLE TO USE FOR CALCULATING THE WATER CONTENT IN THE SYSTEM
Installed Unit
Unit content (*)
Pipe content (**)
Uses (fan-coil, panels, radiators, etc.) (***)
Total content (****)
(*) Consult the technical data table
(**) Consult the pipe water content table
(***) Consult the manual for the installed uses
(****) The water content of the system must be between the minimum and maximum values for the units with hydronic
kit and greater than the minimum value for units without hydronic kit. The minimum value is necessary to provide optimal
comfort.
For units without hydronic kit, add a suitable expansion vessel to the water content of the system.
