SPECIAL FEATURES: AIR CONDITIONING SYSTEM (R 134.a)
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 dryer.
- 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 changing one of the following components, add as below:
- A drying bottle : 15 cc of compressor oil.
- A condenser or an evaporator : 20 cc of compressor oil.
- A high pressure or low pressure pipe : 5 cc of compressor oil.
- A drying cartridge : 15 cc of compressor oil.
