Turn the thermostat to the left to decrease thelevel of ice in bin or to the right to increase the level ofice in bin.Power Button (Green)Pressing the “Power” button once will energize the icemachine and green Power light. Pressing the “Power”button a second time will de-energize the ice machine.Automatic Ice Making Light (Blue)This light is energized when the ice machine is the icemaking position. The light is off when the ice machineis in the clean cycle.Delay StartPressing the “Delay Start” button will initiate a delaycycle. The ice machine will not run until the delay timeexpires.• Pressing the button once will energize the 2 hourlight and initiate a two hour delay period.• Pressing the button a second time will energize the4 hour light and initiate a four hour delay period.• Pressing the button a third time will energize the 8hour light and initiate an eight hour delay period.• Pressing the button a fourth time will cancel thedelay cycle.Part Number 80-01111-9 7/10 95
