  Draining     
1 Unscrew dust caps (1, 4) from test and filler connections (2, 3) of refrigerant lines (A, L) and connect air conditioning service unit    
REFER TO SPECIAL TOOLS 000 588 04 82 00 Air conditioning service unit   WS83.00-P-0031B
IMPORTANT Follow the operating instructions for the air conditioning service unit.  
2 Extract refrigerant IMPORTANT Note down suctioned off oil fill capacity.  
  Evacuate     
3 Clean refrigerant and evacuate air conditioning system    
REFER TO SPECIAL TOOLS 000 588 04 82 00 Air conditioning service unit   WS83.00-P-0031B
IMPORTANT Follow the operating instructions for the air conditioning service unit.  
4 Perform vacuum check of air conditioning system IMPORTANT Follow the operating instructions for the air conditioning service unit.
In the event of pressure loss:
↓
Fill air conditioning with nitrogen and use leak detection spray to check connecting points for leakage. Subsequently drain the air conditioning again and rectify the cause of the pressure loss. Then check air conditioning system for leakage again.		  
Leak detection spray *BR00.45-Z-1002-03A 
Leakage detection for China *BR00.45-Z-1006-03A 
  Filling     
5 Feed new compressor oil into refrigerant circuit NOTES
Pay attention to correct oil fill capacity. Otherwise refrigerant compressor may be damaged.
IMPORTANT Follow the operating instructions for the air conditioning service unit.		  
FLUID SPECIFICATION Total capacity of compressor oil in new A/C compressor See refill tables.
FLUID SPECIFICATION Total capacity of compressor oil in A/C system (incl. A/C compressor)
If A/C system components have been replaced
↓
Consider additional quantities of compressor oil
NOTES
If the refrigerant compressor is removed, no more additional oil quantities may be added. Otherwise, this may lead to malfunction or damage of the air conditioning system.		 See refill tables.
FLUID SPECIFICATION Additional oil filling quantity after sudden emptying of system (e.g. line ruptured) See refill tables.
FLUID SPECIFICATION Additional oil filling quantity after replacing condenser See refill tables.
FLUID SPECIFICATION Additional oil filling quantity after replacing evaporator See refill tables.
FLUID SPECIFICATION Additional oil filling quantity after replacement of suction line See refill tables.
FLUID SPECIFICATION Additional oil filling quantity after replacement of pressure line See refill tables.
FLUID SPECIFICATION Additional oil filling quantity after replacement of desiccant cartridge See refill tables.
FLUID SPECIFICATION Additional oil filling quantity with detectable leakage See refill tables.
FLUID SPECIFICATION Additional oil filling quantity after replacement of complete HK4 roof system See refill tables.
FLUID SPECIFICATION Additional oil filling quantity after replacement of complete HK4 light roof system See refill tables.
6 Charge air conditioning system FLUID SPECIFICATION Total filling capacity, refrigerant See refill tables.
7 Disconnect air conditioning service unit and screw dust caps (1, 4) onto test and filler connections (2, 3) of refrigerant lines (A, L)    
INSPECT Check     
DANGER 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. AS00.00-Z-0005-01A
8 Test run engine and check air conditioning for proper operation at idle speed
