	Check
	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
	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.	Never 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

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 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. Make sure the ambient conditions remain constant. 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.
