Page 6 HOW IT WORKS CSE60 COMPONENT DESCRIPTION Cube Size Control The cube size control is located in front of the control box behind the front panel The sensing capillary tube of the cube size control is routed out of the control box into its bulb holder on the evaporator coil It is a reverse acting temperature control with double throw contacts Turning its knob all the way counterclockwise also shuts off the ice maker The control determines the length of the freezing cycle and correspondingly the size of the cube A lower setting will produce a smaller cube and a higher setting will make a larger cube The cube size control changes its contacts when the evaporator reaches its preset temperature starting the harvest cycle When the sensing tube of the cube size control reaches the high preset temperature the contacts change again restarting the freeze cycle Compressor Toggle Switch The compressor toggle switch is located on the side of the control box When moved to the ON position it makes a circuit to the compressor When moved to the OFF position the other components will still operate High Temperature Cut Out This control senses the temperature of the discharge line and will open to stop the operation of the ice machine should the discharge temperature exceed the preset maximum 175 F After it cools to 140 F it must then be manually reset to restart the machine by pushing the button at the fron
