  • SCOPE

    1 Scope

    1.1 These requirements cover automatic ice makers designed for connection to alternating-current circuits rated not more than 600 volts.

    1.2 These requirements apply to unitary and remote ice makers. For the purpose of this standard, an ice maker includes a means for automatically manufacturing and harvesting ice in cube, flake, or other readily usable form, with or without provision for storage or means of dispensing ice.

    1.3 Self-contained ice makers covered by these requirements employ hermetic refrigerant motor-compressors and air- or water-cooled condensers.

    1.4 These requirements do not apply to ice makers of the tray type, ice vending machines, or to ice makers and ice maker kits used in household refrigerators and freezers.

    1.5 Requirements for the installation of ice makers are included in the National Electrical Code, NFPA 70, and the Safety Code for Mechanical Refrigeration, ASHRAE 15.
