37NORMAL OPERATIONOn units with refrigerator sections, the unit has been designed toachieve a fresh food temperature of approximately 38°F. Units withwith a freezer section (ice maker) are designed to have a freezertemperature of approximately 15°F.On units with ice makers, when the ice bucket is full, the icemaking mechanism will shut off. However, the refrigeration system willcontinue to cool and maintain the cube supply. On frost free icemakerunits, ice production will be lower than on manual defrost units.Ice production may be interrupted by raising the bin arm into an uprightand locked position (the unit will maintain temperature for ice storage,Figure 10).On Combo units, the refrigerator fresh food temperature may vary dur-ing the initial manufacture of ice. It is recommended that the ice buck-et be allowed to fill before placing food in the refrigerator section. Thetemperature control may then be adjusted as needed (allow 24 hoursfor temperature stabilization).Certain sounds are normal during the unit’s operation. You may hearthe compressor or fan motor, the water valve, sounds of defrost, orice dropping into the ice bucket.CAUTIONNEVER use an ice pick, knife, or other sharp instrument toseparate cubes. Shake the bucket instead.The ice bucket MUST be in place to avoid freezing products in therefrigerator section of the Combo Series 29 and 75.During periods of limited usage or high ambient temperatures, it iscommon for cubes to fuse together. Break apart cubes as necessaryby shaking bucket.NOTEControl has been preset at the factory. Allow unit to run for24 hours for temperature stabilization. This factory presetallows for optimal temperature.
