DANGER Risk of fire  due to ignition of R1234yf refrigerant on hot components. Risk of poisoning  caused by inhaling overheated refrigerant vapors. Risk of injury  to skin and eyes caused by contact with escaped R1234yf refrigerant and when working on pressurized parts. Risk of explosion due to formation of ignitable refrigerant/air mixtures 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.

    IMPORTANT The refrigerant analysis must be performed using an analysis device integrated into the air conditioning service unit or an external analysis device with data transfer to the air conditioning service unit.
IMPORTANT A positive gas analysis is when the greenhouse gas exhibits a degree of purity of 92 %.
After a positive gas analysis,
↓
extract refrigerant from air conditioning system into internal container of air conditioning service unit.
After a negative gas analysis,
↓
The gas analysis must be performed up to three times. After a third negative gas analysis, the analysis device must be verified in accordance with the operator's manual. If the analysis device is functional and the gas analysis negative, the refrigerant must be extracted from the A/C system and then be stored in a recycling vessel.

    IMPORTANT The quantity of refrigerant oil extracted from the refrigerant circuit must be documented.  
    IMPORTANT When operating the air conditioning service unit, proceed in accordance with the operator's manual from the manufacturer.  
INSPECT Check     
5 Check receiver drier for re-usability. When one of the following conditions is fulfilled: vehicle is older than 5 years, refrigerant is dirt-laden (color ranges from dark gray to black), refrigerant compressor is jammed, or refrigerant circuit was damaged (e.g. after an accident).
↓
Replace drier cartridge.

    NOTES
Only the approved compressor oil may be used. If it is proven that a different compressor oil has been used, we will refuse to reimburse costs within the warranty and goodwill period. Daimler AG reserves the right to perform reexaminations.		  
    NOTES
The correct oil filling quantity in the refrigerant circuit must be ensured.
In the event of an incorrectly measured oil filling quantity, the refrigerant compressor may be damaged.
