Receiver Dryer: Description and Operation

Receiver drier
The receiver drier acts as a refrigerant reservoir for the system. Any moisture in the system forms as droplets and is absorbed in the drier desiccant.


NOTE: To ensure optimum system operation, replace receiver drier every time refrigerant system is opened.


CAUTION!
The receiver drier may be identified with a label that indicates the drier desiccant inside is only compatible with R-134a refrigerant. NEVER use an R-12 receiver drier in and R-134a system
