25、ing permitted without license from IHS-,-,-I MIL-I-11867K necessary to meet the document requirements. All like items furnished on any one contract, including parts and subassemblies thereof, shall be new and interchangeable. .5 3.2 Design. The ice making machine shall be a complete self-contained u
26、nit composed of an ice-making section and a storage bin. The machine shall have a means of harvesting and storing ice, a water circulating system, motor or motor drives, and all necessary piping, wiring, control and safety devices, and accessories required to provide an automatic operating ice makin
27、g machine with automatic control of ice level in storage bin, All parts shall be located to permit repair or replacement, All operating parts subject to vibration shall be mounted on vibration elimination units to prevent the transmission of vibration during normal use. All accessories, including fa
28、ns, reduction gears, harvesting equipment, and pumps shall be directly connected, V-belt driven (see 3.6.1.1.1), or chain driven except that the evaporator drum, when provided, may be driven by chain from a reduction gear. All chain drives shall be guarded. When the ice machine is operated, all mech
29、anical and electrical controls and parts shall function according to design, and the condensing unit shall not leak when tested in accordance with 4.4.4. When specified for Navy shipboard use (see 6.2), the equipment shall operate satisfactorily when rolled 15 degrees each side of the vertical in-ea
30、ch of two vertical planes at right angles to each other with no spillage of water or ice when tested as specified in 4.4.8. When specified for Navy shipboard use (see 6.2), all types, sizes, and grades of ice making machines shall be equipped with key locking devices on the ice bin covers. Two keys
31、shall be provided with each dispenser. 6.2), the dimensional design shall be such that the machine will pass through a door or hatch having clear dimensions of 26 inches by 66 inches, with corners having an 8-inch radius. Minor disassembly of components to accomplish clearance dimensions is permitte
32、d, but this shall not include disassembly of refrigeration or electrical components. When specified for Navy shipboard use (see 3.2.1 Controls. Controls shall be designed to include a device to automatically operate the ice making machine. The controls shall automatically stop the ice making process
33、 when the predetermined level of ice in the storage bin is reached and automatically restart the ice making process when the amount of ice is reduced below the predetermined level. Controls shall be designed for operation on a nominal 208/230 volt, 1-phase, 60 Hz system or a 115 volt, 1-phase, 60 Hz
34、 system (see 3.6.12). When 50 Hz system is specified (see 6.2), controls shall comply with the operational and electrical requirements. Controls rated at 115 volt, 1-phase, 60 Hz system may be used with a 50 Hz frequency system provided that the power is obtained from either a hot line and neutral o
35、r through a transformer and that the overall performance of the system is not affected. Relays and transformers or any other component necessary for a complete control system shall be. furnished as an integral part of the end item. $c 3.2.2 Capacity. The ice making machine shall be capable of making
36、 and harvesting ice under the conditions in table I when tested in accordance with 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-I-LLb7K 41 777770b 0230547 7 fi MIL-1-1 1867K 4,4,2. Ice produced shall be cube ice (see 6.2). Cube ice normally
37、refers to a fairly uniform product that is hard, solid, usually but not necessarily clear, and generally weighs less than 2 ounces per piece; as distinguished from flake, crushed, or fragmented ice. When specified for Navy shipboard use (see 6.2), the ice making machine shall be capable of making an
38、d harvesting ice having a cooling value of not less than 122 British thermal units (BTU) per pound under the conditions in table I when tested in accordance with 4.4.2. The ice may be formed by any method and in any shape consistent with the manufacturers standard product. TABLE I. Capacity conditio
