4.7.14 Compressor oil
Oil shall be added into the A/C system for lubrication. Compressor oil is solved in the refrigerant
and circulates in the system. When the air conditioning system is shut down, compressor oil will
stay inside the components. If no compressor oil is added into the system when replacing compo-
nents, inadequate lubrication will result. Add compressor oil according to the chart below:

CAUTION
●
Add oil into a new compressor according to the required volume of the system. When
the compressor is to be replaced, discharge the surplus oil in it.
●
Over-fi lling of compressor oil will reduce the refrigerating capacity. Short of compres-
sor oil in the system will cause compressor abnormality.
●
Protect pipe joints and O-rings from contamination when disassembling the compres-
sor.
