Removal and Replacement Parts lists and wiring diagrams are located in the center of this manual, printed on yellow paper. It is an alert for important safety information on a hazard that might cause serious injury. [. . . ] For proper operation, the ice thickness should be set to the 1 11 /16" diameter. The machine is designed to harvest cubes of only the correct thickness. Correct Size & Shape 1 11/16" Cube Size Diagram Cubes Too Thick Cubes Too Thin January 1993 Page 12 KAD 62V40/05 Initial Start Up Note: If the first batch of cubes are not all uniform discs, some ice machine cleaner should be added to the reservoir. After ice has been harvested, but before new cubes begin to form, switch the ICE/OFF/WASH switch to WASH. Remove the splash guard, and drain the reservoir by removing the drain elbow. Replace all parts, turn on the water and move ICE/OFF/WASH switch to ICE. The machine will have to harvest all of the cubes before it goes back into the freeze cycle. Check operation of the bin control circuit by holding ice on the bin control tube in the bin. If the ice maker does not stop within 1 minute, while keeping ice on the thermostat, rotate the bin thermostat shaft counter clockwise until the ice maker does stop. Remove the ice from the capillary tube; the ice maker should restart within 2 minutes. If it does not, rotate the adjusting shaft clockwise until the machines starts. The ice machine is now ready for automatic operation.

Wipe all interior surfaces of the ice storage bin with the bleach and water. Mix a cleaning solution of 4 ounces of Scotsman Ice Machine Cleaner to 4 pints of warm (950F. -1100F. ) water. Using rubber gloves, dip a nylon scouring pad into the cleaning solution and scrub the scale off the liner. After the scale has been removed, rinse all surfaces inside the bin with clean, potable water. Stainless Steel Bin Liner The stainless steel liner of the bin will require periodic cleaning. Chemicals in the water supply, such as chlorine, cause brown stains to appear on the surface of the stainless steel parts. General Cleaning - staining is usually removed by washing the parts with ordinary cleaning powder such as Bon-Ami or Copper-Glo and water. It can be removed from the water supply by using a charcoal or activated carbon water filter to treat the water to the ice machine. Exterior Cabinet Cleaning: The exterior cabinet may be cleaned by scrubbing with soap and water. A nylon type brush may be used to scrub stubborn deposits.

[. . . ] The pump should be operating whenever the machine is in the freeze cycle. Inlet Water Valve The valve may plug-up from minerals in the water, and may be cleaned rather than replaced. Unscrew the fitting at the top of the valve, and pull the water inlet tube out of the valve body. Reverse above steps to replace.
