Procedures

A new compressor is supplied filled with a full charge of (X cubic cm) of refrigerant oil.

A new compressor is supplied with an oil fill (X cm) of 120 cubic cm.

A calculated quantity of oil must be drained from the new compressor before fitting. To calculate the quantity of oil to be drained:
1 Remove the drain plug from the old compressor.
2 Invert the compressor and gravity drain the oil into a calibrated measuring cylinder. Rotate the compressor clutch to ensure the compressor is completely drained.
3 Note the quantity of oil drained (Y cubic cm).
4 Calculate the quantity of oil to be drained from the new compressor using the following formula:
X. cubic cm - (Y cubic cm + 20 cubic cm) Q cubic cm
5 Remove the drain plug from the new compressor and drain Q cubic cm of oil.
6 Fit and tighten the compressor drain plug.

System components
When renewing system components, add the following quantities of refrigerant oil:
- Condenser = 40 cubic cm
- Evaporator = 30 cubic cm
- Receiver drier = 15 cubic cm
- Pipe or hose = 5 cubic cm
