A commercial ice machine uses a remote air-cooled condenser connected by a line set that was brazed during installation, and the completed circuit holds about nine pounds of refrigerant. Which certification covers service on that circuit?
Correct Answer
A) Type II, because the circuit was assembled in the field and holds more than five pounds
This machine fails the small appliance test twice over. The refrigerant circuit was completed on the job site rather than sealed at the factory, and the charge is above the five-pound ceiling. Either failure alone would take it out of Type I; together they put it clearly in the field-assembled high-pressure class that Type II covers. Note that a different ice machine, one that arrives self-contained and factory sealed with a charge under the limit, would be Type I. The same product name can land in either category depending on how the unit is built and piped.
Why This Is the Correct Answer
Small appliance status requires factory manufacture, factory charge, factory hermetic seal, and five pounds or less. A remote-condenser ice machine is field piped and field charged and exceeds the charge limit, so it is a high-pressure appliance and Type II applies.
Why the Other Options Are Wrong
Option B: Type I, because ice machines are listed as small appliances no matter how they are piped
No equipment is small-appliance by product name. Self-contained ice makers often qualify, but a field-piped remote system does not, because the circuit was never sealed at the factory.
Option C: Type III, because the equipment serves a food service refrigeration load
Type III is for low-pressure appliances whose refrigerant boils above room temperature. The application the equipment serves has nothing to do with the pressure class.
Option D: Type I, because the nine-pound charge is divided between two separate sections
The charge limit applies to the appliance, not to individual sections of it. Splitting a circuit across two locations does not split its charge for classification purposes.
Memory Technique
Remote condenser means remote from Type I. If a line set crosses the building, it is Type II.
Reference Hint
40 CFR 82.152 small appliance definition: factory manufactured, charged and hermetically sealed, 5 lbs or less. Field-piped equipment above that limit is Type II under 40 CFR 82.161.
