Refrigerant changeover guidelines CFC R502 to HFC R404A/R507.

Type of article: Article

Summary

The paper states that retrofitting systems that employ compressors manufactured prior to 1973 are not recommended. This is due to the different materials used in motor insulation systems that have not been evaluated for compatibility with the new refrigerants and lubricants. It details the changeover procedure for systems with and without service valves.
