Adjusting the Temperature
Your new freezer 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
Freezers are set to cycle between a minimum temperature of -5 degrees Fahrenheit and a maximum
temperature of 2 degrees Fahrenheit.
Adjusting the temperature changes the minimum temperature at which your unit will run. Your unit
will not run constantly at this setting. To change it, follow these instructions:
Digital Control Units
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 display “dor”.
1. Hold down the menu button for 3s, (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 7s, the digital display will automatically save and exit, and
return to the normal display interface.

Automatic Alarms
Automatic alarms are programmed to sound on your unit in the following instances:
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:
Defrost System
Refrigerator coils are kept below the freezing point (32° F). During compressor down-time, 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. Freezer coils are defrosted electrically. Automatic defrost
timers automatically initiate at pre-set intervals and for a pre-determined duration.
1. Press and hold the menu key for 3s 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 7s, the digital display returns to the normal display interface
Refrigerator Cabinet High/Low Temperature Alarm:
• When the temperature reaches 8 degrees F above your
set point for 30 minutes
• When the temperature reaches 1 degree F below your
set point for 30 minutes
• If the refrigerator is above the temperature of 41
degrees F for 30 minutes
Freezers Cabinet High/Low Temperature Alarm:
• When the temperature reaches 10.4F degrees, which is
18F degrees above your set point, for 30 minutes
