Recovery cylinders used with R-410A must have a DOT rating of: - either "DOT 4BA 400" or "DOT 4BW 400" A system using R-410A refrigerant has bubbles in the sight glass. Technician A says that the system must be low on refrigerant. Technician B says that the bubbles could be caused by the blended refrigerant flashing in the increased volume of the sight glass. Who is correct? - Technician B only When charging a R-410A system that uses a thermostatic expansion valve, proper charge can be...

Appliance : any device that contains and uses a refrigerant for household or commercial purposes, including any air conditioner, refrigerator, chiller, or freezer. EPA interprets this definition to include all air-conditioning and refrigeration equipment except units designed and used exclusively for military purposes.
