NOTE
The board contains another set of pins similar to the Degrees C/Degrees F selection jumper, marked

manufacturing process. DO NOT CONNECT THE J1 PINS TOGETHER.

a. Press the OFF key to shut down the unit.
b. Hold both the Manual Defrost key and ON key momentarily in order to display parameters.

the unit will remain in defrost once defrost is initiated. The defrost duration can be selected by scroll-
ing through available options (10, 20, 25, 30 or 45 minutes) using the + or - keys. Selection MUST
