User manual SCOTSMAN SLE400R

[. . . ] SLE400R Introduction To the owner or user: This service manual is intended to provide you, and the maintenance or service technician, with the information needed to install, start up, clean, maintain and repair this product. The SLE400R is an ice machine that produces cubed ice on 6 vertical cube freezing surfaces. When harvested, the cubes fall individually into the ice storage bin. The SLE400R automatically maintains the level of ice by turning on when the ice level falls, and switches off when the bin is full. [. . . ] The water pump will begin to pump water over the evaporators. Normal water level is 1/8" below the high point of the lower curve of the siphon u-tube. The water level in the reservoir should drop to the bottom curve of the U-bend (normal water level) in about 2 minutes. If not, check for proper drain tube connections. Remove cap from "king" or service valve on the receiver, and open the valve. The remote fan motor will begin to turn, and warm air will be discharged from the top of the remote condenser. The water temperature in the reservoir will soon be 320F. , and ice should begin to form on the evaporators. Allow the ice machine to operate for about 20 minutes. The ice should be fully formed and should be harvested within a few minutes. Compare a fresh cube to the diagram on the back of the front panel. If needed, adjust the cube size by loosening the set screws and moving the ice thickness probe adjustment plate. Move the adjustment plate down for smaller cubes and up down for larger. 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. January 1995 Page 13 Cubes Too Thin Cubes Too Thick Cube Size Diagram Correct Size & Shape 1 11/16" SLE400R 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. of ice machine cleaner to the reservoir. Allow unit to operate that way for 10 minutes. 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 next batch of ice should be uniform. 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. [. . . ] The pump does not need oil, but if it becomes noisy, overheats, or will not pump it should be replaced. Be certain to confirm electrical faults with a voltmeter or ohmmeter before replacing the pump. The pump should be operating whenever the machine is in the freeze cycle. Unplug or disconnect the electrical power. [. . . ]
