How to Calculate the Quantity of Adding Refrigerant
X The outdoor unit is loaded with sucient R-410 A refrigerant for 24.6 ft(7.5 m) of piping.
If you have used more than “24.6 ft(7.5 m)”, add "A" of refrigerant for extra meter.
The quantity of additional refrigerant is variable according to the installation situation. Thus, make sure the outdoor unit
situation before adding refrigerant.
This operation can only be performed by a qualied refrigeration specialist.
