(*) Consult the technical data table.
(**) Consult the pipe water content table.
(***) Consult the manual from the relevant manufacturer.
(****) The water content of the system must be greater than the minimum value for units without hydronic kit. The minimum
value is necessary to provide optimal comfort.
Detailed installation schematics can be found at the back of the manual.
Should you require further technical assistance call your local office – details on the back page of this manual.
Do not use the heat pump to treat industrial process, swimming pool or sanitary water. In all these
cases, provide an intermediate heat exchanger.
