The cube size control should only be adjusted to bring the cubes to the correct shape the overall size cannot be adjusted Try to adjust the cube size control when the ice machine is in the harvest cycle or in the first 10 minutes of the freeze cycle 1 Open the door and remove the control box cover 2 Locate the cube size adjustment screw and to make fuller cubes turn the screw clockwise about 1 4 turn This will make the freezing cycle longer 3 To shorten the freezing cycle and make cubes that are not as full turn the adjustment screw 1 4 turn counterclockwise 4 After the next freezing cycle the cubes should have responded to the adjustment if another adjustment is required do it early in the freeze cycle SIDE VIEW OF CUBES TOO BIG CORRECT SIZE CUBE SIZE ADJUSTMENT TOO SMALL September 2011 Page 18 ADJUSTMENTS DCE33 Bin s ice level When the ice machine shuts off the ice level in the bin should be even with the metal tube inside the bin If the ice in the bin is too high or low turn the ice machine control knob to adjust the bin thermostat 1 To lower the ice level turn the knob counterclockwise Usually a 1 8 turn will be enough 2 To increase the ice level turn the knob clockwise Usually a 1 8 turn will be enough Timer up to DCE33A 1BD or DCE33PA 1BD The amount of harvest time may be adjusted It is preset from the factory at about 3 minutes which

17. This concentrates most of the impurities in the ice machine water reservoir where they may form hard deposits known as scale The DCE33 dilutes the concentration of minerals by over filling the reservoir during the harvest cycle with the excess water flowing down the drain About 3 quarts of water flow into the unit each cycle About 1 quart of that rinses the reservoir and goes down the drain Some impurities will inevitably remain and will Stick to the parts in the machine and will cause malformed ice cubes Eventually built up mineral scale can shorten machine life To keep the machine operating properly these impurities or minerals will have to be regularly dissolved by an acid cleaning using Scotsman Ice Machine Cleaner Directions for this may be found in the section under cleaning In general it is always a good idea to filter the water A water filter if it is of the proper type can remove taste and odors as well as particles Some methods of water treatment for dissolved solids include reverse osmosis and polyphosphate feeders A reverse osmosis system should include post treatment to satisfy the R O water s aggressiveness Deionized water is not recommended Because water softeners exchange one mineral for another Scotsman does not recommend their use for ice machines Where water is very hard softened water may result in white mushy cubes that stick together Scotsman suggests that if in doubt about t
