HFC-134a (R-134a) Service Tool and EquipmentINFOID:0000000005396482
Never mix HFC-134a refrigerant and/or its specified oil with CFC-12 (R-12) refrigerant and/or its oil.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/oil.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or oil) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid mixed
use of the refrigerants/oil.
Adapters that convert one size fitting to another must never be used refrigerant/oil contamination will occur
and compressor failure will result.

OIL
1. Before connecting recovery/recycling equipment to vehicle, check recovery/recycling equipment gauges.
No refrigerant pressure should be displayed. If NG, recover refrigerant from equipment lines.
2. Discharge refrigerant into the refrigerant recove ry/recycling equipment. Measure oil discharged into the
recovery/recycling equipment.
3. Drain the oil from the old (removed) compressor into a graduated container and recover the amount of oil drained.
4. Drain the oil from the new compressor into a separate, clean container.
5. Measure an amount of new oil installed equal to amount drained from old compressor. Add this oil to new compressor through the suction port opening.
6. Measure an amount of new oil equal to the amount recovered during discharging. Add this oil to new com- pressor through the suction port opening.
7. If the liquid tank also needs to be replaced, add another 5 m (0.2 US fl oz, 0.2 Imp fl oz.) of oil at this
time.
Add this 5 m (0.2 US fl oz, 0.2 Imp fl oz.) of oil only when replacing the compressor.

SETTING OF SERVICE TOOLS AND EQUIPMENT
Discharging Refrigerant
WARNING:
Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Remove HFC-134a (R-134a) refrigerant from the A/C system using certified service equipment meeting
requirements of SAE J2210 HFC-134a (R-134a) r ecycling equipment or SAE J2201 HFC-134a (R-134a)
recovery equipment. If an accidental system dischar ge occurs, ventilate the work area before resum-
ing service. Additional health and safety information may be obtain ed from the refrigerant and oil man-
ufacturers.
