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.
