If the stop valve of your Daikin Air Conditioner's outdoor unit is closed and there is insufficient refrigerant, begin by opening the stop valve on both the gas and liquid sides. Verify that the additional refrigerant charge was completed correctly. Recalculate the necessary amount of refrigerant according to the piping length, and then add the appropriate amount of refrigerant.
