	Filling
8	Add new compressor oil to the refrigerant circuit according to the oil filling quantity noted during extraction
	Compressor oils (specification 362.0)		BB00.40-P-0362-00A
		Only use the approved compressor oil in each case. If it is proven that a different compressor oil has been used, we will refuse to reimburse costs within the warranty and goodwill period. Daimler AG reserves the right to perform reexaminations. Correct oil filling quantity in refrigerant circuit must be corrected. In the event of an incorrectly measured oil filling quantity, the refrigerant compressor may be damaged.
