Check Air Conditioning System For Leakage - AR83.30-P-1761XG

Model 463 

as of model year 2019 

	Risk of explosion  when using a forming gas with incorrect mixing ratio. Risk of suffocation  due to inhalation of forming gas. Risk of injury  due to bursting of high-pressure hoses.	Wear safety glasses and protective gloves. No smoking or open flames. Work in well-ventilated rooms only.	AS83.00-Z-0001-02A
	Procedure for a damaged or leaky air conditioning system		AH83.30-N-0004-01A
	Check
1	Evacuate air conditioning system.		AR83.30-P-1760XG
2	Fill air conditioning with forming gas and check pressure drop.
	000 588 19 21 00 Leak tester	Follow the instructions in the leak tester user's manual. Only fill air conditioning system with forming gas when the engine is cold. Temperature changes during the pressure test (e.g. because of change in weather or cooling down of the engine compartment) cause pressure fluctuations. Consistent ambient conditions must therefore be strictly ensured.	WS83.00-P-0035B
		Pressure drop in refrigerant circuit filled with test gas	*BE83.30-P-1001-04A
3	Identify leakage on air conditioning system using gas detection unit.	If there is a pressure drop in the refrigerant circuit.
	000 588 03 21 00 Gas detector	Pay attention to the user's manual of the leak tester and the gas detection unit. If a leakage is present, ↓ Replace the damaged component parts of the air conditioning system.	WS47.00-P-0019B
4	Release forming gas from leak tester.
5	Fill the air conditioning system.		AR83.30-P-1760XG
