Type I — Small AppliancesCâu 101 / 240
Which appliance would NOT be recovered under the small-appliance rules?
a.A room dehumidifier sealed at the factory
b.A 10-ton packaged rooftop unit with a 30-pound R-410A charge
c.A PTAC unit holding 4 pounds of refrigerant
d.A household refrigerator with 1.5 pounds of refrigerant
Giải thích
A packaged rooftop unit holding 30 pounds of refrigerant far exceeds the five-pound limit and is a Type II appliance, not a small appliance. Household refrigerators, factory-sealed dehumidifiers, and PTAC units within the five-pound limit are small appliances. The key test is factory-sealed construction with five pounds or less of refrigerant.
