Refrigerant Recovery

CAUTION: Use extreme care and observe all safety and service precautions related to the use of refrigerants. Failure to do so could contribute to environmental pollution.

If a Rotunda Mobile Recycling Center 023-00150 or equivalent recycling station is used, the following general procedures should be observed as well as the operating instructions provided by the manufacturer:

1. Connect refrigerant recycling station hoses to vehicle A/C service ports and recovery station inlet fitting.
2. Turn power to the recycling station on to start recovery process. Allow recycling station to pump refrigerant from the system until the vehicle system pressure is reduced to a vacuum. On some systems, the pump will be shut off automatically by a low-pressure switch in the electrical system. On other units, it may be necessary to manually turn off the pump.
3. Once the recycling station has evacuated vehicle A/C system, close the station inlet valve (if equipped). Then switch off electrical power.
4. Allow vehicle A/C system to remain closed for about two minutes. Observe system pressure/vacuum levels as shown on the gauge. If pressure does not rise, disconnect recycling station hoses.
5. If system pressure rises, repeat Steps 2, 3 and 4 until the vacuum level remains stable for two minutes.
6. Perform required service operations. Evacuate and recharge the A/C system.
