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.
