Other Refrigerant System Components

DURING COMPONENT REPLACEMENT
When replacing other components of the air conditioning system, measured quantities of the specified refrigerant oil should be added to the component to make sure that the total oil charge in the system is correct before the system is operated.

Clean refrigerant oil should be poured directly into the replacement components as follows:

NOTE: Add an additional 60 ml (2 oz) when repairing a leak.

^ A/C evaporator core: add 90 ml (3 oz).
^ A/C condenser core: add 30 ml (1 oz).
^ Suction accumulator/drier: drain oil from removed suction accumulator/drier. Add same amount plus 60 ml (2 oz) of clean refrigerant oil to new suction accumulator/drier.

If any other component such as an orifice tube or a hose is replaced, no additional refrigerant oil is necessary unless a hose bursts with a fully charged system. Then, additional refrigerant oil may be necessary with the amount to be determined by the technician. The suction accumulator/drier should also be replaced under this circumstance.

Replacement of other refrigerant system components such as hoses, O-rings, and pressure switches does not require the addition of refrigerant oil.
