Plug the unit into a dedicated 15 amp outlet. The unit must be the only device on the circuit. Confirm the Drain Tubing outlet is properly grounded and is in good condition. Worn outlets should be replaced as they can cause erratic operation of equipment. Do not use an extension cord. Do not cut off the ground plug on the power cord. Ground fault outlets are not recommended. If ground fault is required a ground fault breaker should be used. Use the services of a licensed electrician when needed and conform to local and national codes. Position the unit in its final location. Level the unit front to back and left to right.Potable Water ConnectionAll models:Note: Wall mounting limits access to the utilityconnections which are at the back bottom ofthe machine. Pre-plumbing the water and drainis required so that stubs are available for finalconnection to water and drain.Connect the potable water supply tube to the 3/8inch male flare inlet at the bottom back of the unit.Water filters may be used but are not required. Notethat activated carbon or charcoal water filters areused for taste and odor problems but also take outany chlorine that the local water agency may haveadded for purification. That can require more frequentsanitization of the equipment. March 2015 Page 8

If yes, push Dispense Ice button. Does the motor activate? If yes, go to next row. If no, check for voltage at motor. If no voltage, replace controller. If voltage at motor, replace motor. Agitator or rotor not turning, remove all ice and inspect for damage to agitator and rotor. Restore water. Remove upper front panel, check controller indicator lights. Hold container in front of sensor, does the Water Dispense Sensed light glow? If no, sensor is not detecting the container. If yes, does the Water Dispense light glow? If yes, push Dispense Water button. Does the water valve activate? If no, check for voltage at valve. If no voltage, replace controller. If voltage at valve, replace valve. A few drops per minute is normal. Check bin drain tube at basin. This is normal and can vary depending upon how much air is in the water. May be improved by lowering water pressure to the unit.
