Refrigerant Oil

Add refrigerant oil after replacing the following parts:
Condenser: 10 cc (1/3 fl oz)
Evaporator: 10 cc (1/3 fl oz)
Line or hose: 20 cc (2/3 fl oz)
Receiver: 10 cc (1/3 fl oz)
Compressor: 120 ± 10 cc (4 fl oz) - Volume of oil from removed compressor = Volume to drain from new compressor
On compressor replacement, subtract the volume of oil drained from the removed compressor from 120 ± 10 cc (4 fl oz). and drain the calculated volume of oil from the new compressor.
