AIR
CONDITIONING
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 circuit.
When changing one of the following components, add the quantity stated:
- A drying bottle : 15 cc of compressor oil.
- A condenser or an evaporator : 20 cc of compressor oil.
- High pressure or low pressure pipework : 5 cc of compressor oil.
- A drying cartridge : 15 cc of compressor oil.
