22 166240008 3/17/95 The water regulating valve must close off condenser water flow completely during the “hot gas”harvest cycle. There should be no discharge water flowing out of the condenser during the harvest cycle. Should the valve fail to close during the harvest mode, the condenser will conti...

23 166240008 3/17/95 Readings in the range listed below 100 Meg-Ohm would be an indicator that the system being tested may have a contamination problem. Where does the problem come from? As an example, the filter drier may become sat- urated and hold large percentages of moisture and the system func...

25 166240008 3/17/95 Leak Detection The new non-chlorine based refrigerants [HP - 62/R 404A] require special leak detection devices other than what has been standard for the CFC’s. While the instruments for leak detection are different, the processes have not changed. Basics to remember: 1. Look for...

27 166240008 3/17/95 Chemical analysis is the key requirement to the definition of “Reclaim”.
