These requirements cover automatic ice makers designed for connection to alternating-current circuits rated not more than 600 volts. 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. Self-contained ice makers covered by these requirements employ hermetic refrigerant motor-compressors and air- or water-cooled condensers. 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. 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. A product that contains features@ characteristics@ components@ materials@ or systems new or different from those covered by the requirements in this standard@ and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features@ characteristics@ components@ materials@ or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development@ revision@ and implementation of this standard.
