amount of lubricant leakage.)

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 refrigerant leak is small, no addition of lubricant is needed.
LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT
1. Before connecting ACR4 to vehicle, check ACR4 gauges. No refrigerant pressure should be displayed. If
NG, recover refrigerant from equipment lines.
2. Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure lubricant discharged into
the recovery/recycling equipment.
3. Drain the lubricant from the old (removed) compressor into a graduated container and recover the amount
of lubricant drained.
4. Drain the lubricant from the new compressor into a separate, clean container.
5. 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.
6. Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant
to new compressor through the suction port opening.
7. If the liquid tank also needs to be replaced, add an additional 5 m [Liter] (0.2 Imp fl oz.) of lubricant at
this time.
Do not add this 5 m (0.2 Imp fl oz.) of lubricant if only replacing the compressor.

9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine OFF and perform leak check again following steps 4 through 6 above.
Refrigerant leaks should be checked immediately after stopping the
engine. Begin with the leak detector at the compressor. The pres-
sure on the high-pressure side will gradually drop after refrigerant
circulation stops and pressure on the low-pressure side will gradually
rise, as shown in the graph. Some leaks are more easily detected
when pressure is high.
11. Before connecting ACR4 to vehicle, check ACR4 gauges. No refrigerant pressure should be displayed. If
pressure is displayed, recover refrigerant from equipment lines and then check refrigerant purity.
12. Discharge A/C system using approved refrigerant recovery equipment. Repair the leaking fitting or com-
ponent as necessary.
13. Evacuate and recharge A/C system and perform the leak test to confirm no refrigerant leaks.
14. Conduct A/C performance test to ensure system works properly.
