	Risk of explosion  caused by welding or soldering work on closed air conditioning system. Risk of poisoning  caused by inhaling overheated refrigerant vapors. Risk of injury  to skin and eyes caused by contact with liquid refrigerant.	Do not perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated areas. Carry out repair work on the air conditioning system circuit only after the system has been drained.	AS83.00-Z-0001-01A

1	Connect air conditioning service unit and evacuate air conditioning system	Model 450.3, 450.4 (except 450.418) with code I01 (Air conditioning Plus) Model 450.3, 450.4 (except 450.418) with code I29 (Air conditioning Plus (with combination filter and outside temperature indicator), smart&passion)	AR83.30-P-1760SM

2	Fill air conditioning system with nitrogen
	000 588 10 21 00 Leak tester	Fill system with a system pressure of 15 bar only when engine is cold. This system pressure must be maintained for at least 4 h. Fill high and low-pressure side of air conditioning with nitrogen. Temperature changes during the pressure test can cause pressure surges, e.g. due to weather changes, transition from day to night, cooling down of engine compartment. Consistent ambient conditions must be strictly ensured.	WS83.00-P-0008B
3	Check A/C circuit for leaks using leak-detecting spray	Only if there is a pressure loss and no leak can be detected in the refrigerant circuit. Leak detection spray	*BR00.45-Z-1002-03A
		Leakage detection spray for USA	*BR00.45-Z-1004-03A
4	Check complete engine compartment using an ultraviolet lamp and remove any existing contrast agent residue with an engine wash	Except model 451.390/392/490/492 Only if there is a pressure loss and no leak can be detected in the refrigerant circuit. Commercially available devices/tools:  Air conditioning leak detector
5	Drain nitrogen
6	Refill A/C	Model 450.3, 450.4 (except 450.418) with code I01 (Air conditioning Plus) Model 450.3, 450.4 (except 450.418) with code I29 (Air conditioning Plus (with combination filter and outside temperature indicator), smart&passion)	AR83.30-P-1760SM

7	Check refrigerant circuit for leaks using leak-detector additive	Except 451.390/392/490/492 Only if there is a pressure loss and no leak can be detected in the refrigerant circuit. Carry out steps as per the operating instructions of the UV leak detection kit. Use only the approved MB leak detector additive. If it is proven that a different leak detector additive has been used, we will refuse to reimburse costs within the warranty and goodwill period.
