Air Conditioning Compressor Replacement

A new compressor is supplied filled with a full charge of (X cm³) of refrigerant oil. Refer to the ’CAPACITIES, FLUIDS AND LUBRICANTS’ section of this manual for the actual capacities.

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 cm³).
4. Calculate the quantity of oil to be drained from the new compressor using the following formula: X cm³ - (Y cm³ + 20 cm³) = Q cm³
5. Remove the drain plug from the new compressor and drain Q cm³of oil.
6. Fit and tighten the compressor drain plug.
