How much refrigerant does the condensing unit normally contain when installing a split system air conditioner?

When installing a split system air conditioner, the condensing unit typically contains enough refrigerant for just the condensing unit alone. This is because, during the initial installation, the condensing unit is charged with a specific amount of refrigerant necessary for its own operation. The complete system is usually charged by drawing in additional refrigerant from the condensing unit into the evaporator and the connecting lines. Therefore, while the condensing unit has its own charge, the total charge required for the entire system includes what is needed for both the condensing unit and the evaporator, as well as the interconnecting refrigerant lines. This is why the notion that the condensing unit contains enough refrigerant solely for itself is correct in this context.
