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.

1. Before connecting recovery/recycling equipment to vehicle, check recovery/recycling equipment gauges.

No refrigerant pressure should be displayed. If NG, recover refrigerant from equipment lines.

2. Connect recovery/recycling equipment to vehicle. Confirm refrigerant purity in supply tank using recovery/

recycling equipment and refrigerant identifier. If NG, refer to 

HA-4, "Contaminated Refrigerant"

.

3. Confirm refrigerant purity in vehicle A/C system using recovery/recycling equipment and refrigerant identi-

fier. If NG, refer to 

HA-4, "Contaminated Refrigerant"

.

4. Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure electric compressor oil

discharged into the recovery/recycling equipment.

5. Drain the electric compressor oil from the “old” (removed) electric compressor into a graduated container

and recover the amount of electric compressor oil drained.

6. Drain the electric compressor oil from the “new” electric compressor into a separate, clean container.
7. Measure an amount of new electric compressor oil installed equal to amount drained from “old” electric

compressor. Add this electric compressor oil to “new” electric compressor through the suction port open-

ing.

8. Measure an amount of new electric compressor oil equal to the amount recovered during discharging.

Add this electric compressor oil to “new” electric compressor through the suction port opening.

9. If the liquid tank also needs to be replaced, add an additional 5 m  (0.2 US fl oz, 0.2 Imp fl oz) of electric

compressor oil at this time.

sor oil when replacing liquid tank

D.

Install new electric compressor oil

Do not add the 5 m  (0.2 US fl oz, 0.2 Imp fl oz) of electric compressor oil if only replacing the

electric compressor and not the liquid tank.

HFC-134a (R-134a) Service Procedure

INFOID:0000000004215277

SETTING OF SERVICE TOOLS AND EQUIPMENT

WARNING:

Avoid breathing the A/C refrigerant and electric compressor oil vapor or mist. Exposure may irritate

eyes, nose, and throat. Remove the HFC-134a (R-134a) from the A/C system using certified service

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

134a recovery equipment). If an accidental system discharge occurs, ventilate the work area before

resuming service. Additional health and safety information may be obtained from the refrigerant and

electric compressor oil manufacturers.

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.
