Refrigerant Recovery

The use of refrigerant recovery and recycling stations allows the recovery and reuse of refrigerant after contaminants and moisture have been removed.
When using a recovery or recycling station, follow the manufacturer's operating instructions, noting the following:
1. Use extreme caution and observe all safety and service precautions related to use of refrigerants.
2. Connect refrigerant recycling station hose(s) to vehicle A/C service port(s) and recovery station inlet fitting. Hoses used should have shutoff devices or check valve within 12 inches of hose ends to minimize introduction of air into recycling station and to minimize amount of refrigerant released when hose(s) is disconnected.
3. Turn recycling station On to start recovery process. Allow recycling station to pump refrigerant from A/C system until station pressure gauge indicates vacuum.
4. After vehicle A/C system has been evacuated, close station inlet valve, if equipped.
5. Turn station Off. On some stations the pump will automatically be turned Off by a low pressure switch.
6. Allow vehicle A/C system to remain closed for approximately two minutes. Observe vacuum level indicated on gauge. If pressure does not rise, disconnect recycling station hose(s).
7. If system pressure rises, repeat steps 3 through 6 until vacuum level remains stable for two minutes.
8. Service A/C system as necessary, then evacuate and recharge A/C system.
