This unit is preset at the factory to defrost once every 6 hours for general conditions. 
However, if it is determined that this interval does not suit actual conditions, the interval 
can be changed. To change the defrost interval, follow the steps below.

1) Press and hold both the

 button and the 

 service button for 5 seconds. If "F0" is 

not displayed, press the MANUAL DEFROST button until "F0" appears in the display 
window.

2) Press the 

 service button to display the current setting (default: 6). Press the 

 up 

or 

 down button to increase or decrease the number of hours between each defrost. 

The interval can be from 1 to 12 hours in increments of 1 hour.

3) Press the 

 service button to save the setting.

4) Press the MANUAL DEFROST button to return to the menu screen. Press and hold 

both the

 button and the 

 service button for 5 seconds to exit the setting mode 

and return to the temperature display.

Note:

• The defrost is a heated defrost, and therefore has a tendency to raise cabinet 

temperature.

• Cabinet temperature is not displayed during defrost; "dF" is displayed in its place. 
• The change in the defrost setting will take effect immediately. The next defrost will 

take place after the newly set time interval has elapsed.

• Initiating a manual defrost will restart the defrost timer.
• The evaporator temperature must be below the defrost completion temperature for 

any defrost (manual or auto) to be initiated.

This value should only be changed after consulting with the factory. To change the 
differential, follow the steps below. 

1) Press and hold both the

 button and the 

 service button for 5 seconds. "F0" should 

appear in the display window. Press the MANUAL DEFROST button until "F2" appears 
in the display window.

2) Press the 

 service button to display the current + setting (default: 3.6°F (2.0°C) for 

both refrigerators and freezers. The decimal between the digits is not displayed). Press 
the 

 up or 

 down button to increase or decrease the + (plus) differential in .9°F 

(.5°C) increments. 
Note: The + value can be adjusted between 0.0 and 6.3°F in .9°F increments (0.0 to 

3.5°C in .5°C increments).

3) Press the 

 service button to save the + setting. The - (minus) sign will flash and the 

display will change to the - (minus) differential setting (default: -3.6°F (-2.0°C) for both 
refrigerators and freezers). The decimal between the digits is not displayed).
