*AMS 10-6: If the length of the refrigerant pipes exceeds 15 metres, extra refrigerant must be added at a rate of 0.02 kg/m.
AMS 10-8/12/16: If the length of the refrigerant pipes exceeds 15 metres, extra refrigerant must be added at a rate of 0.06 kg/m.
** Refers to circulating volume.
External circulation pump must be used when the pressure drop in the system is greater than the available external pressure. In such cases,
a bypass line with a non-return valve must also be installed.
A bypass valve must be used if min. system flow cannot be guaranteed.
