Capacity and selection data
3.4 Selection method
To select the outdoor units, it will be necessary to consult and/or use a series of parameters shown in tables and graphics
presented in the di󰀨erent chapters of this handbook. A summarized list is shown below:
For cooling and heating maximum capacities: refer to chapters 3.1&3.2.
For cooling and heating correction factor depending on the piping length: refer to chapters 3.3.1.
For Hi-Therma Monobloc series, heating correction factor owing to use of glycol: refer to chapters 3.3.2.
For heating correction factor owing to deforst operation: refer to chapters 3.3.3.
3.4.1 Selection procedure
For selecting the unit capacity, perform the selection procedure with checking the refrigerant concentration at leakage in order
not to exceed the maximum permissible concentration.
