		 When connecting and when operating the air conditioning service unit, the complete work procedure must be conducted in accordance with the operator's manual as issued by the manufacturer.
3	Drain air conditioning system	 The volume of compressor oil extracted must be documented.
4	Use the air conditioning service unit to clean the refrigerant and evacuate the refrigerant circuit
5	Conduct vacuum test using air conditioning service unit	In the event of pressure loss.

		 Only the approved compressor oil may be used. 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 compressor oil in the refrigerant circuit. Otherwise, a wrongly measured oil filling capacity could damage the refrigerant compressor.
		 If the refrigerant compressor is removed, no more additional oil quantities may be added. Otherwise, this may lead to malfunction or damage of the air conditioning system.
