HA-18 < ON-VEHICLE MAINTENANCE > OIL ON-VEHICLE MAINTENANCE OIL Maintenance of Electric Compressor Oil Quantity in Electric Compressor INFOID:0000000004215276 CAUTION: Use only Electric Compressor Oil ND-OIL 11 for the electric compressor of the air conditioning sys- tem. Using other A/C oils may damage the A/C system as they may conduct electricity. The electric compressor oil in the electric compressor circulates through the system with the refrigerant. Add electric compressor oil to electric compressor when replacing any component or after a large refrigerant leak- age has occurred. It is important to maintain the specified amount. If electric compressor oil quantity is not maintained properly, the following malfunctions may result: • Lack of electric compressor oil: May lead to a seized electric compressor • Excessive electric compressor oil: Inadequate cooling (thermal exchange interference) ELECTRIC COMPRESSOR OIL • Electric compressor oil type: Electric Compressor Oil ND-OIL 11 CHECKING AND ADJUSTING CAUTION: If excessive electric compressor oil leakage is noted, do not perform the electric compressor oil return operation. Set the following conditions: Test Conditions • Hybrid System READY: Depress the push-button ignition switch two times to the ON position, then depress the brake pedal and depress the push-button ignition switch once for the ready light to illu- minate indicating the Hybrid System is in READY mode. • A/C switch: On • Blower fan speed: Max. position • Temperature control: Optional [Set so that intake air temperature is 25 ° to 30° C (77° to 86°F).] • Intake position: Recirculation ( ) • Perform electric compressor oil return operation for about ten minutes Adjust the electric compressor oil quantity according to the following table. Electric Compressor Oil Adjusting Procedure for Components Replacement Except Electric Compressor After replacing any of the following major components, add the correct amount of electric compressor oil to the system. Amount of Electric Compressor Oil to be Added * If refrigerant leak is small, no addition of electric compressor oil is needed. Electric Compressor Oil Adjustment Procedure for Electric Compressor Replacement Part replaced Electric Compressor Oil to be added to system Remarks Amount of electric compressor oil m (US fl oz, Imp fl oz) Evaporator 35 (1.2, 1.2) — Condenser 15 (0.5, 0.5) — Liquid tank 5 (0.2, 0.2) Add if electric compressor is not replaced. In case of refrigerant leak 30 (1.0, 1.1) Large leak — Small leak * |
