Compressor lubricant.  
ESSENTIAL: The compressor lubricant is extremely hygroscopic; always use FRESH oil.  
Checking the compressor oil level.  
There are three specific cases :  
1) Repairs to a system without leaks.  
2) Slow leak.  
3) Fast leak.  
1) Repairing a system without leaks.  
a) Using draining/recovery equipment not fitted with an oil decanter.  
- Drain the system as slowly as possible via the LOW PRESSURE valve, so as not to lose any oil.  
- No more oil should be added when filling the system with R 134.a fluid.  
b) Using draining/filling equipment fitted with an oil decanter.  
- Drain the R 134.a fluid from the system in accordance with the instructions in the equipment handbook.  
- Measure the amount of oil recovered.  
- Add the same amount of NEW oil when filling the system with R 134.a fluid.  
c) Replacing a compressor.  
- Remove the old compressor, drain it and measure the oil quantity.  
- Drain the new compressor (supplied full), so that the same amount of NEW oil is left in the compressor as was in the old compressor.  
- No more oil should be added when filling the system with R 134.a fluid.

Checking the compressor oil level (continued)  
2) Slow leak.  
- Slow leaks do not lead to oil loss, therefore the same procedure should be followed as if there was no leak at all.  
3) Fast leak.  
- This type of leak causes both oil loss as well as allowing air to enter the system.  
It is therefore necessary to  
- Replace the dehydrator.  
- Drain as much oil as possible (when replacing the faulty component).  
Either before or during filling of the system with R 134.a fluid, introduce 80 cc of NEW oil into the system.

If all these conditions are met, take the following action :  
- Start the engine, with the air conditioning off, and wait for the cooling fan

Preliminary conditions.  
- Operate the air conditioning and set the engine speed to 2500 rpm.  
Position of the air conditioning controls :  
- Maximum cold air.  
- Air blower in maximum position.  
NOTE : If the ambient temperature reaches 40 °C, the engine speed will  
return to 2000 rpm in order to prevent the compressor from being cut off

After the air conditioning has been on for three minutes, measure :  
- the ambient temperature in the workshop,  
- the temperature of the air coming from the central vents.  
Conditions and vehicle equipment.  
- Boot closed.  
Compare the two values using the table overleaf.  
- Doors and windows shut.  
- Ensure the vehicle is in a sheltered area (away from wind, sun, etc..).
