Refrigerant System Service Equipment

When servicing air conditioning system, a R-134a refrigerant recovery/recycling/charging station meeting SAE Standard J2210 must be used. Refer to operating instructions supplied by equipment manufacturer for proper care and use of this equipment. A manifold gauge set may be needed with some recovery/recycling/charging equipment. The service hoses on gauge set being used should have manual (turn wheel), or automatic back-flow valves at service port connector ends. This will prevent refrigerant from being released into atmosphere.
