CONDITIONING
SPECIAL FEATURES : AIR CONDITIONING SYSTEM (R 134.a)
ALL TYPES
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.
