HFC-134a (R-134a) Service Tool and Equipment

• Never mix HFC-134a (R-134a) refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/

or its lubricant.

• Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/

lubricant.

• Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles

refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.

• Never use adapters that convert one size fitting to another: refrigerant/lubricant contamination occurs and

compressor malfunction may result.

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.

Is it successful?

YES

>> GO TO 2.

NO

>> GO TO 3.

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

>> Refer to "LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT".

NO

>> Refer to "LUBRICANT ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT

EXCEPT COMPRESSOR".

LUBRICANT ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT EXCEPT COM-
PRESSOR

After replacing any of the following major components, add the correct amount of lubricant to the system.
Amount of lubricant to be added:

*1: If the refrigerant leak is small, no addition of lubricant is needed.

1.

Before connecting recovery/recycling recharging equipment to vehicle, check recovery/recycling recharg-
ing equipment gauges. No refrigerant pressure should be displayed. If NG, recover refrigerant from equip-
ment lines.

2.

Connect recovery/recycling recharging equipment to vehicle. Confirm refrigerant purity in supply tank
using recovery/recycling recharging equipment and refrigerant identifier. If NG, refer to

HA-170, "Working

with HFC-134a (R-134a)"

.

3.

Confirm refrigerant purity in vehicle A/C system using recovery/recycling recharging equipment and refrig-
erant identifier. If NG, refer to

HA-170, "Working with HFC-134a (R-134a)"

.

4.

Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure lubricant discharged into
the recovery/recycling equipment.

5.

Drain the lubricant from the old (removed) compressor into a graduated container and recover the amount
of lubricant drained.

6.

Drain the lubricant from the new compressor into a separate, clean container.

7.

Measure an amount of new lubricant installed equal to amount drained from old compressor. Add this
lubricant to new compressor through the suction port opening.

8.

Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant
to new compressor through the suction port opening.

9.

If the liquid tank also needs to be replaced, add another 5 m (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant at
this time.
Do not add this 5 m (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant when replaces the compressor only.
