	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
	Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.	Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	AS00.00-Z-0005-01A

1	Evacuate air conditioning system	MODEL 190, 197	AR83.30-P-1760RQ

		MODEL 216, 221 (except 221.095/195)	AR83.30-P-1760SX
2	Fill air conditioning system with nitrogen	Fill system with a system pressure of 15 bar only when engine is cold. This system pressure must be maintained for at least 4 hours. 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. Air conditioner pressure and leak tester (mobile)
3	Check air conditioning system refrigerant circuit for leaks	Check for leaks using a leak detection spray in case of pressure drop.
		Leakage detection spray for USA	*BR00.45-Z-1004-03A
		Leak detection spray In the event of pressure loss and no leak can be found in the refrigerant circuit, see: Check refrigerant circuit with leak detector additive.	*BR00.45-Z-1002-03A
4	Drain nitrogen
5	Light up the complete engine compartment with a UV lamp, if necessary remove the remains of the existing contrast agent using special cleaner and wash the engine
6	Charge air conditioning system with refrigerant	MODEL 190, 197	AR83.30-P-1760RQ

		MODEL 216, 221 (except 221.095/195)	AR83.30-P-1760SX
7	Check leaktightness of refrigerant circuit using leak detector additive	Carry out steps as per the operating instructions of the UV leak detection kit. Use only the approved 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. Daimler AG reserves the right to perform reexaminations.
8	Examine refrigerant circuit of air conditioning system for leak detector additive	If no leak is detected in the refrigerant circuit: ↓ Remove expansion valve
