3.8 FUNCTIONAL/STRUCTURAL PART — A part used to maintain the intended relative physical position of fixed or moving parts, or maintain the integrity of the structure. A cabinet liner that supports an electrical component is considered to be a functional part.
3.9 HARVEST CYCLE — The function of removing or separating the manufactured ice from the evaporator.
3.10 ICE MAKER (CYCLIC) — An automatic ice maker that has separate and sequential water fill, freezing, and harvesting phases of ice-making operation.
3.11 NONFUNCTIONAL PART — A part, such as thermal insulation or decorative material, that does not serve as electrical insulation or to support or enclose electrical components, maintain electric spacings, or protect against injury to persons.
3.12 ICE MAKER (NONCYCLIC) — An automatic ice maker that has simultaneous water supply, freezing. and harvesting phases in the ice-making operation.
3.12.1 OPERATING CONTROL — A control intended to start, regulate, or operate the appliance during normal operation, An example would be a thermostat or temperature controller.
3.13 PRESSURE VESSEL — Any refrigerant-containing receptacle of a reffigerating system other than evaporators (each separate section of which does not exceed 1/2 cubic feet (0.014 m3) of refrigerant containing volume], evaporator coils, compcessors, condenser cods, controls, headers, pumps, and piping.
