Which unit on a service list meets the EPA definition of a small appliance under Section 608?
Correct Answer
A) A window air conditioner that was assembled, charged, and hermetically sealed at the factory with 2 pounds of R-410A
A small appliance is a product that leaves the factory fully assembled, charged, and hermetically sealed with 5 pounds or less of refrigerant. A factory-sealed window air conditioner with a 2 pound charge fits that description exactly. Charge size alone is not the test. A split system is field-piped and field-charged, so it never qualifies no matter how small the charge is, and larger package units and remote rack systems are field-assembled high-pressure equipment that fall under Type II.
Why This Is the Correct Answer
Room air conditioners are on the EPA's own list of small appliances, and this one meets all three parts of the definition: it was assembled at the factory, charged at the factory, and hermetically sealed at the factory, with a charge well under the 5 pound ceiling. A Type I certified technician may recover refrigerant from it.
Why the Other Options Are Wrong
Option B: A residential split-system air conditioner holding 4 pounds of refrigerant that was charged during field installation
The charge is under 5 pounds, but the system was piped and charged in the field. Factory sealing is part of the definition, so a split system is Type II equipment regardless of how little refrigerant it holds.
Option C: A rooftop package unit holding 12 pounds of refrigerant
Twelve pounds is well over the 5 pound ceiling, and a rooftop package unit is field-connected high-pressure equipment. Servicing it requires Type II certification.
Option D: A supermarket display case piped to a remote parallel compressor rack
A case fed by a remote rack is field-assembled and shares a charge far larger than 5 pounds. Remote systems are Type II work and cannot be treated as small appliances.
Memory Technique
Three factory F's: Fully assembled, Filled, and Firmly sealed at the factory, all under 5 pounds.
Reference Hint
Small appliance definition, 40 CFR 82.152: fully manufactured, charged, and hermetically sealed at the factory with 5 pounds or less of refrigerant.
