Freon Recovery Procedures
Freon RecoveryCAUTION: Automotive refrigerant containing CFC's is hazardous to the earth's atmosphere. To protect our environment, use an Underwriter's Laboratory (UL) approved refrigerant recovery/recycling unit such as Kent-Moore ACR3, or equivalent, whenever discharging an A/C system.
NOTE: Characters in ( ) denote applicable points in the image.
1. Remove protective caps from A/C service valves
2. Close both valves on A/C manifold gauge set
3. Connect hose (1) from low pressure gauge to low pressure service valve
4. Connect hose (3) from high pressure gauge to high pressure service valve
5. Connect manifold gauge hose (2) to inlet connection (4) on refrigerant recovery recycling unit (5)
CAUTION: Always follow manufacturer's instructions when using a refrigerant recovery/recycling unit.
6. Following manufacturer's instructions, discharge A/C system into refrigerant recovery/recycling unit
NOTE: Disconnect electrical connector from A/C compressor clutch, to prevent accidental compressor operation while system is discharged
7. Close manifold gauge valves when refrigerant is fully discharged
8. Disconnect manifold gauge set hose from service valves
9. Reinstall protective caps on service valves
CAUTION: Do not leave A/C system open for long periods of time. Prolonged exposure to the air will contaminate the system and necessitate replacement of receiver/drier and possibly other system components.
