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

Model 205 

Model 213 

Model 253 

Model 293 

	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
Topical note	Procedure for a damaged or leaky air conditioning system		AH83.30-N-0004-01A
	Check
1	Evacuate air conditioning system.	Model 205, 213, 253	AR83.30-P-1760LW
		Model 293	AR83.30-P-1760EQ
2	Carry out preliminary check for pressure drop test. 000 588 19 21 00 Leak tester	Model 213 with Code 1U6 (R744 Refrigerant) Pay attention to the leak tester operator's manual.	WS83.00-P-0035B
		Do not fill air conditioning system with forming gas unless Engine is cold. Preliminary test for pressure drop test	*BE83.30-P-1002-04A
3	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.	WS83.00-P-0035B
		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. 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. 000 588 03 21 00 Gas detector	If no pressure drop was detected. 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-0019B
5	Release forming gas from leak tester.
6	Fill air conditioning.	Model 205, 213, 253	AR83.30-P-1760LW
