Additional refrigerant 30 m Three room (A + B + C) Multi, Non. Additional refrigerant 40 m C A · Minimum piping length : A or B or C = 2 m or more A or B = 7 m or more Outdoor for one unit for heat pump unit · Maximum indoor piping length : A or B or C = 20 m or less B · Maximum piping height difference : A or B or C = 10 m or less · Maximum piping / height difference between two rooms = 10 m or less 4.
