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
