3 - CONNECTIONS

3.1 - REFRIGERANT CONNECTIONS

To define the refrigerant connection lines between the internal and external units, refer to the table below.
Maximum length of the connection pipes (m)
Elevation difference limit between the two units if the external
unit is positioned higher (m)
Elevation difference limit between the two units if the external
unit is positioned lower (m)
Additional load of refrigerant per metre beyond 15 metres of
pipes (g/m)
Exclusively use pipes with diameters which respect the required dimensions.
The maximum length of the connection lines to the internal unit MUST be compliant with the table
in paragraph "3.1" topping up the load of R32 as envisaged (see par.3.1.2). Do not install the units
beyond the maximum allowed difference in level between internal and external unit.
Complete the refrigerant circuit by connecting the internal unit with the external unit by means of the insulated
copper pipes.
