Giải thích
A factory-manufactured, hermetically sealed water cooler with five pounds or less of refrigerant meets the small-appliance definition. Rooftop units, supermarket racks, and field-charged split systems are larger, non-sealed, or assembled on site and are Type II or Type III equipment. Typical small appliances include refrigerators, freezers, window units, dehumidifiers, PTACs, and vending machines.
