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

Model 223 

	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-1760S
2	Carry out preliminary check for pressure drop test.
	000 588 37 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.	WS83.00-P-0067B
3	Fill air conditioning with forming gas and check pressure drop.
	000 588 37 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-0067B
		Pressure drop in refrigerant circuit filled with test gas	*BE83.30-P-1001-04A
4	Check for leakage on air conditioning system using gas detection unit.	If no pressure drop was detected.
	000 588 31 21 00 Gas detection unit	Pay attention to the operator's manual of the leak tester and the gas detection unit. If there is a problem, ↓ Replace the damaged component parts of the air conditioning system.	WS47.00-P-0077B
5	Release forming gas from leak tester.
6	Fill air conditioning.		AR83.30-P-1760S
