YES >> GO TO 11.
NO >> GO TO 8.
11 .CHECK REFRIGERANT LEAKAGE
1. Connect refrigerant recovery/recycling recharging equipment or manifold gauge set (SST).
2. Charge the refrigerant of approximately 200 g to the refrigerant system.
3. Check for refrigerant leakage. Refer to HA-32, "
Inspection".
NOTE:
When using electrical leak detector (SST). Refer to HA-33, "
Inspection".
Is the inspection result normal?
YES >> GO TO 12.
NO >> Repair or replace parts according to the inspection results.
12.CHARGE REFRIGERANT
1. Connect recovery/recycling recharging equipment or manifold gauge set (SST).
2. Evacuate air again.
3. Charge the specified amount of refrigerant to the refrigerant system.
>> GO TO 13.
13.CHECK REFRIGERANT LEAKAGE
Check for refrigerant leakage again. Refer to HA-32, "
Inspection".
NOTE:
When using electrical leak detector (SST). Refer to HA-33, "
Inspection".
Is the inspection result normal?
YES >> GO TO 14.
NO >> GO TO 6.

LUBRICANT
Maintenance of Lubricant QuantityINFOID:0000000003795916
The lubricant in the compressor circulates through the system the refrigerant. Add lubricant to compressor
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
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 normally.
There is no evidence of a large amount of lubricant leakage.
CAUTION:
Never perform the lubricant return operation if excessive lubricant leakage is detected.
Is it successful?
YES >> GO TO 2.
NO >> GO TO 3.
2.PERFORM LUBRICANT RETURN OPERATION
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
- Set temperature: FULL HOT
- Intake position: Recirculation (REC)
2. Perform lubricant return operation for approximately 10 minutes.
3. Stop the engine.
>> GO TO 3.
3.CHECK REPLACEMENT PART
Should the compressor be replaced?
YES >> Refer to HA-29, "Lubricant Adjusting Procedure for Compressor Replacement".
NO >> Refer to HA-28, "
Lubricant Adjusting Procedure for Components Replacement Except Compres-
sor".

Refrigerant LeakagesINFOID:0000000003795979
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage may indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electrical leak detector or fluorescent dye leak
detector (SST: J-42220).
Confirm the leakage with an electrical leak detector if dye is observed. It is possible a prior leakage was
repaired and not properly cleaned.
Do not stop when one leakage is found but continue checking for additional leakages at all system compo-
nents and connections when searching for leakages.
Move the probe along the suspected leakage area at 1 to 2 inches per second and no further than 1/4 inch
from the component when searching for refrigerant leakages using an electrical leak detector.
CAUTION:
Moving the electrical leak detector probe slower and closer to the suspected leakage area improves
the chances of finding a leakage.
