	Checking
	Risk of accident  caused by vehicle starting off by itself when engine is running. Risk of injury  caused by contusions and burns during starting procedure or when working near the engine as it is running	Secure vehicle to prevent it from moving 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 refrigerants.	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 emptied.	AS83.00-Z-0001-01A

1	Evacuate air conditioning system	Air conditioning service unit
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 circuit for leakage.	Check for leaks using a leak detection spray in case of pressure drop.	*BR00.45-Z-1002-03A
