Warning | Risk of poisoning caused by inhaling overheated refrigerant vapors from an air conditioning system containing R134a. Risk of injury to skin and eyes caused by contact with liquid R134a refrigerant and when working on pressurized parts | 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 rooms. Carry out repair work on the air conditioning system circuit only after the system has been evacuated. | |

| 000 588 04 82 00 Air conditioning service unit R134a | ||
When connecting and when operating the air conditioning service unit, the complete work procedure must be conducted in accordance with the operator's manual as issued by the manufacturer. | |||
3 | Drain air conditioning system | The volume of compressor oil extracted must be documented. | |
4 | Check desiccant cartridge for re-usability | If necessary. | |
| |||
Replace drier cartridge. | |||
| |||
| |||
| |||
5 | Use the air conditioning service unit to clean the refrigerant and evacuate the refrigerant circuit | ||
6 | Conduct vacuum test using air conditioning service unit | If the air conditioning service unit shows a fault message, then this is an indication that there is a leak in the refrigerant circuit. | |
| |||
Check air conditioning system for leakage. | |||
Fill, check leaktightness | |||
7 | Add new compressor oil to the refrigerant circuit according to the oil filling quantity noted during extraction | ||
| Compressor oils (specification 362.0) | ||
| |||
| |||
| |||
Depending on the repair case, the oil filling quantity may need to be adjusted accordingly. | |||

Warning | Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. | Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | |
12 | Run engine at idle speed for about 4 minutes and check all the component functions which are of relevance for proper operation of the air conditioning system |
