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

INFOID:0000000001098152

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/lubri-
cant.
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.
Adapters that convert one size fitting to another must never be used: refrigerant/lubricant contamination will
occur and compressor malfunction will result.

LUBRICANT RETURN OPERATION

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

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.

>> GO TO 3.

PERFORM LUBRICANT RETURN OPERATION, PROCEEDING AS FOLLOWS

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)

Perform lubricant return operation for about 10 minutes.

Stop the engine.

>> GO TO 3.

CHECK REPLACEMENT PART

Should the compressor be replaced?

YES

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

>> 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.
