SPECIAL FEATURES: AIR CONDITIONING SYSTEM (R 134.a)
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.
Having changed any of the following components, the quantities to be added are:
- A drying bottle
- A condensor or an evaporator
- A high pressure or low pressure pipe
- A drying cartridge
Checking the compressor oil level (continued)
: 15 cc of compressor oil.
