Construction Requirements7.1 The dishwashing machine shall be complete so thatwhen connected to the specified source of power, water supply,heating means (steam, electric, or gas), drainage, detergent,and rinse agent feeder as applic
29、able, the unit can be used for itsintended function. Dishwashers shall be rigid, quiet in opera-tion, free from objectionable vibration, and so constructed as toprevent objectionable splashing of water to the outside of themachine. The machine shall be equipped with splash curtainsto prevent excessi
30、ve splash and spray carryover. Parts requiringadjustment or service, or both, shall be readily accessible fromthe front and side of the machine. The machine shall befurnished with a loading and unloading section. The machineshall wash dishes by means of a water and detergent solutionpumped from a ta
31、nk and shall final rinse the dishes with freshwater from an outside source. The machine may include apumped rinse prior to the final sanitizing rinse. Provisions shallbe made to fill the wash and rinse tank either directly from theregular hot water supply with a hand valve or through theF860072boost
32、er or solenoid, or both. The dishwashing machine shallhave a conveyor belt suitable for handling eating and drinkingutensils, the conveyor belt shall be protected by an adjustableslip clutch or other device. Means shall be provided forreleasing or disconnecting the driving power, or the drive, incas
33、e of jamming. The conveyor belt shall be driven by amotor-driven gear reduction unit. The wash, pumped rinse, andfinal rinse treatment shall be controlled by means of theconveyor speed as determined by NSF/ANSI 3 for multipletank conveyor type machines. The final rinse spray controlshall have a posi
34、tive return to the “off” position when there isno tableware in process to ensure the conservation of final rinsewater. The machine shall be provided with tracks of corrosion-resisting steel not less than 0.070 in. thick, or other corrosion-resisting material. Dishwashers shall have an inside working
