(1) Calculation formula
The amount of refrigerant to be added depends on the size and the length of field piping. (unit in m[ft])
1) When the distance between HBC and outdoor unit is longer than 30.5m:
Amount of added refrigerant (kg) = (0.21xL
2) When the distance between HBC and outdoor unit is 30.5m or shorter:
Amount of added refrigerant (kg) = (0.23xL
