Adjusting the Temperature

Your new refrigerator is already factory set to run at optimum temperatures for food safety and should require no adjustments.

Refrigerators are set to cycle between a minimum temperature of 33 degrees Fahrenheit and a maximum temperature of 40 degrees Fahrenheit.

Adjusting the temperature changes the minimum temperature your unit will run at. Your unit will not run constantly at this setting. To change it, follow these instructions:

Controller

1. Hold down the menu button for 3 seconds. At this time, the display screen displays “–”, then background button lights up.
2. Select button and click. At this time, enter temperature setting interface. The display screen displays the current set value.
3. Adjust the downtime temperature value used by the user pressing .
4. After the adjustment, click the menu button to return the menu selection interface.
5. Wait for about 7 seconds. The digital display will automatically save and exit and return to the normal display interface.

Always remember to calculate the differential if you change the minimum temperature setting. The cabinet temperature will fluctuate up to +7 degrees over your set minimum temperature as the compressor runs and shuts off. Setting the temperature too high will result in unsafe maximum temperatures and possible health code violations.

Your Z Series unit compressor will continue to run when the door is left ajar. After 15 minutes of being left ajar, an audible alarm will sound. At the same time, the display board will

Running a Manual Defrost Cycle

This unit is pre-programmed to run automatic defrost cycles at preset intervals. However, if you would like to run a manual defrost cycle at any time, please follow the steps below:

1. Press and hold the menu key for 3 seconds to enter the menu selection interface. At this time, the display screen displays “–”, then background button lights up.
2. Click the button in the upper left corner to start manual defrosting.
3. Wait for about 7 seconds. The digital display returns to the normal display interface.

Defrost System

Refrigerator coils are kept below the freezing point (32 degrees Fahrenheit). During compressor downtime, the evaporator fan continues to circulate air through the evaporator coil. This air circulation raises the coil temperature above the freezing point, melting any accumulated frost. Run-off water is drained into the evaporator pan and evaporated. Automatic defrost timers automatically initiate at pre-set intervals and for a pre-determined duration.
