Maintenance of Lubricant Quantity in Compressor

NJS0002W

The lubricant in the compressor circulates through the system with the refrigerant. Add lubricant to compres-
sor when replacing any component or after a large refrigerant leakage occurred. It is important to maintain the
specified amount.
If lubricant quantity is not maintained properly, the following malfunctions may result:

●

Lack of lubricant: May lead to a seized compressor.

●

Excessive lubricant: Inadequate cooling (thermal exchange interference)

LUBRICANT RETURN OPERATION

Adjust the lubricant quantity according to the test group shown below.

1. 

CHECK LUBRICANT RETURN OPERATION

Can lubricant return operation be performed?

●

A/C system works properly.

●

There is no evidence of a large amount of lubricant leakage.

CAUTION:

If excessive lubricant leakage is noted, never perform the lubricant return operation.

2. 

PERFORM LUBRICANT RETURN OPERATION, PROCEEDING AS FOLLOWS

1.

Start the engine, and set to the following conditions:

–

Engine speed: Idling to 1,200 rpm

–

A/C switch: ON

–

Blower speed: Max. position

–

Temp. control: Optional [Set so that intake air temperature is 25 to 30

°

C (77 to 86

°

F).]

–

Intake position: Recirculation (REC)

2.

Perform lubricant return operation for about 10 minutes.

3.

Stop the engine.

>> GO TO 3.

3. 

CHECK REPLACEMENT PART

Should the compressor be replaced?

YES

>> GO TO 

ATC-27, "LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACE-

MENT"

 .

NO

>> GO TO
