		 The refrigerant analysis must be performed using an analysis device integrated into the air conditioning service unit or an external analysis device with data transfer to the air conditioning service unit.
		 A positive gas analysis is when the greenhouse gas exhibits a degree of purity of 92 %.
		After a negative gas analysis.
		
		The gas analysis must be performed up to three times. After a third negative gas analysis, the analysis device must be verified in accordance with the operator's manual. If the analysis device is functional and the gas analysis negative, the refrigerant must be extracted from the A/C system and then be stored in a recycling vessel.
		After positive gas analysis.
		
		The refrigerant must be extracted from the air conditioning system into the internal air conditioning service unit container.
