How to Set a Custom Defrost Schedule

Begin with the defrost timer on normal Operation Mode: The SET CLOCK light is blinking rapidly and the PROGRAM and DEFROST ON lights are off. If all switches are OFF (Fig. 15), the factory preset defrost schedule is enabled: 2 AM, 8 AM, 2 PM, 8 PM.

•Determine your own best defrost schedule. The upper set of switches represents the AM hours; the lower switches represent the PM hours. Allow a minimum of 2 hours between the start of any two defrost cycles.

•To customize your defrost schedule, begin with all switches OFF (Fig. 15).

•With the SET CLOCK light blinking rapidly, as in normal Operation Mode, slide the switches to the right that correspond to the hour when each defrost cycle should begin.

•If you want a defrost cycle to begin on the half-hour, slide the two adjacent switches to the right. For example, to start a defrost cycle at 2:30 PM, Slide switches 2 and 3 to the right in the lower set of switches.

Custom Defrost Schedule Example #1 (Fig. 16) shows five defrost cycles that begin at 1 AM, 6 AM, 10 AM, 2:30 PM and 8 PM.

Custom Defrost Schedule Example #2 (Fig. 17) shows six defrost cycles that begin at 1 AM, 4 AM, 10 AM, 2:30 PM, 6 PM and 9:30 PM.

During normal operation, leave these switches set on the desired defrost schedule if it is other than the factory preset schedule.
