OIL
Revision: June 20062007 Versa
2. Discharge refrigerant into the refrigerant recovery/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
WAR NIN G:
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) recycling equipment or SAE J2201 HFC-134a (R-134a)
recovery equipment. If an accidental system discharge occurs, ventilate the work area before resum-
ing service. Additional health and safety information may be obtained from the refrigerant and oil man-
ufacturers.
