At power up, the initial Defrost Interval (dI) does not have a Defrost Cycle (dFt).

Subsequent defrost intervals (dI) begin with the selected dFt value.
•
All defrost intervals have the same length. To set up a regular or timed defrost cycle: 1. Select a dI value between 2 hours

and 24 hours.
Note: A dI value of 0 indicates no defrost interval. 2. Select a dFt value between 1 minute and 99 minutes.
