Refrigerant: Tools and Equipment
Charging Station/Recycling Device
When servicing an air conditioning system, an A/C charging station and a refrigerant recovery/recycling device for R-134a should be used. This device
must meet SAE standard J221O. Contact an automotive service equipment supplier for charging and refrigerant recycling/recovering equipment. Refer to
the operating instructions provided with the equipment for proper operation.
Fig.1 Manifold Gauge Set
A manifold gauge set must also be used in conjunction with the charging and/or recovery/recycling device. The service hoses on the gauge set being used
should have manual (turn wheel) or automatic back flow valves at the service port connector ends. This will prevent refrigerant from being release into
the atmosphere.
