3. Amount of refrigerant to be added
The amount of refrigerant that is shown in the table below is factory-charged to the outdoor units.
The amount necessary for extended pipe (field piping) is not included and must be added on site.
(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
