OIL

Maintenance of Oil Quantity in Compressor

INFOID:0000000009882411

The oil in the compressor circulates through the system with the refrigerant. Add oil to compressor when

replacing any component or after a large refrigerant leakage has occurred. It is important to maintain the spec-

ified amount.

If oil quantity is not maintained properly, the following malfunctions may result:

• Lack of oil: May lead to a seized compressor

• Excessive oil: Inadequate cooling (thermal exchange interference)

WARNING:

Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.

Remove HFC-134a (R-134a) refrigerant from the A/C system using certified service equipment meeting

requirements of SAE J2210 HFC-134a (R-134a) recycling equipment or SAE J2201 HFC-134a (R-134a)

recovery equipment. If an accidental system discharge occurs, ventilate the work area before resum-

ing service. Additional health and safety information may be obtained from the refrigerant and oil man-

ufacturers.

OIL

Maintenance of Oil Quantity in Compressor

INFOID:0000000009882413

The oil in the compressor circulates through the system with the refrigerant. Add oil to compressor when

replacing any component or after a large refrigerant leakage has occurred. It is important to maintain the spec-

ified amount.

If oil quantity is not maintained properly, the following malfunctions may result:

• Lack of oil: May lead to a seized compressor

• Excessive oil: Inadequate cooling (thermal exchange interference)

CHECKING AND ADJUSTING

CAUTION:

If excessive oil leakage is noted, do not perform the oil return operation.

Start the engine and set the following conditions:

Test Condition

• Engine speed: Idling to 1,200 rpm

• A/C switch: On

• Blower fan speed: MAX position

• Temp. control: Optional [Set so that intake air temperature is 25

° to 30° C (77° to 86°F)]

• Intake position: Recirculation (

)

• Perform oil return operation for about ten minutes

Adjust the oil quantity according to the following table.

Oil Adjusting Procedure for Components Replacement Except Compressor

After replacing any of the following major components, add the correct amount of oil to the system.

Amount of Oil to be Added

• *1: If refrigerant leak is small, no addition of oil is needed.
