Limits To The Length And Height Difference Of Refrigerant Pipes - Ferroli DIAMANT M Série Manuel D'utilisation Et D'entretien

2.4 LIMITS TO THE LENGTH AND HEIGHT DIFFERENCE OF REFRIGERANT PIPES

The length of the refrigerant pipes between the indoor and outdoor units must be as short as possible and is in any case limited by
compliance with the maximum height difference values between the units.
Diminution of the difference in height between the units (H+,H-) and of the pipe lengths (L) will limit the load losses, consequently
increasing the overall efficiency of the machine.
Comply with the limits given in the following tables.
Model
Liquid connection
Gas connection
Max length
Maximum single unit length
Max difference level
Maximum length with standard charge
Additional refrigerant charge per meter
Contact our technical department for the required modifications if the units must operate beyond the specifications given above.
