Lubricant Adjusting Procedure for Compressor Replacement
INFOID:0000000003545468
1.
Check recovery/recycling recharging equipment gauges before connecting recovery/recycling recharging
equipment to vehicle. No refrigerant pressure should be displayed. Recover refrigerant from equipment
lines if NG.
2.
Connect recovery/recycling recharging equipment to vehicle. Confirm refrigerant purity in supply tank
using recovery/recycling recharging equipment and refrigerant identifier. Refer to
if NG.
3.
Confirm refrigerant purity in vehicle A/C system using recovery/recycling recharging equipment and refrig-
erant identifier. If NG, refer to
HA-12, "Working with HFC-134a (R-134a)"
