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

Model 238 

	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
Notice	Procedure for a damaged or leaky air conditioning system		AH83.30-P-0004-01KOA
	Check
1	Evacuate air conditioning system		AR83.30-P-1760LWO
2	Fill air conditioning with forming gas and check pressure drop
	000 588 19 21 00 Leak tester	Pay attention to the leak tester operator's manual. Do not fill air conditioning system with forming gas unless engine is cold. Temperature changes during the pressure test (e.g. through change in weather or cooling down of the engine compartment overnight) can cause pressure surges. 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	Check for leaks in air conditioning system using gas detection unit	If no pressure drop was detected.
	000 588 03 21 00 Gas detector	Pay attention to the operator's manual of the leak tester and the gas detection unit. In the event of leakage ↓ Replace damaged components of the air conditioning system.	WS47.00-P-0019B
4	Release forming gas from leak tester
5	Charge air conditioning system		AR83.30-P-1760LWO
