What should technicians ensure about equipment when using R-410A?

Technicians must ensure that the equipment has compatible lubricants when using R-410A because the refrigerant operates at higher pressures compared to older refrigerants like R-22. R-410A requires specific lubricants that can withstand these pressures and maintain effective lubrication to prevent compressor failure and other operational issues. Using incompatible lubricants can lead to system failures, decreased efficiency, and potential damage to the equipment.

Having compatible lubricants is crucial for ensuring the longevity and reliability of the refrigeration system. In contrast, equipment designed to operate at standard R-22 pressures would not be suitable since R-410A operates at significantly higher pressures. Furthermore, equipment designed for R-28 refrigerants would not necessarily be compatible with R-410A, and assuming that special training isn’t needed overlooks the fact that handling and installing R-410A systems does require specific knowledge and skills to manage the associated safety and operational considerations effectively.
