16. A Caution Do not use the existing refrigerant piping e The old refrigerant and refrigerator oil in the existing piping contain a large amount of chlorine which will cause the refrigerator oil in the new unit to deteriorate R410A is a high pressure refrigerant and the use of the existing piping may result in bursting Keep the inner and outer surfaces of the pipes clean and free of contaminants such as sulfur oxides dust dirt shaving particles oils and moisture Contaminants inside the refrigerant piping will cause the refrigerant oil to deteriorate Use a vacuum pump with a reverse flow check valve e If other types of valves are used the vacuum pump oil will flow back into the refrigerant cycle and cause the refrigerator oil to deteriorate Do not use the following tools that have been used with the conventional refrigerants Prepare tools that are for exclusive use with R410A Gauge manifold charging hose gas leak detector reverse flow check valve refrigerant charge base vacuum gauge and refrigerant recovery equipment e f refrigerant and or refrigerant oil left on these tools are mixed in with R410 or if water is mixed with R410A it will cause the refrigerant to deteriorate e Since R410A does not contain chlorine gas leak detectors for conventional refrigerators will not work A Caution Store the piping to be used during installation indoors and keep both ends of the piping sealed
