Maintenance of Lubricant Quantity in CompressorEJS000TH
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 gas leakage occurred. It is important to maintain the speci-
fied 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.
YES or NO
YES >> GO TO 2.
NO >> GO TO 3.
2. PERFORM LUBRICANT RETURN OPERATION, PROCEEDING AS FOLLOWS:
1. Start engine, and set the following conditions:
–Test condition
Engine speed: Idling to 1,200 rpm
A/C or AUTO 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 engine.
CAUTION:
If excessive lubricant leakage is noted, do not perform the lubricant return operation.
>> GO TO 3.
3. CHECK COMPRESSOR
Should the compressor be replaced?
YES or NO
YES >> Go to AT C - 2 5 , "LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACE-
MENT" .
NO >> GO TO 4.With gasoline engine
