DEFROST TIMER (Low Temperature Units and Convertible Models in Low Temperature Mode) —
When power is initially applied to the cabinet, the exterior dial of the defrost time clock (Fig. 5) must
be set to the correct time of day.
To access the defrost timer, remove the front
trim panel (Fig. 4) by lifting up and out. Open
door on the defrost timer box. Turn the inside
knob counterclockwise until the exterior dial is
positioned so the correct time of day is at the
time of day pointer. Replace the front trim
panel when done.
The defrost timer (Fig. 5) is set at the factory
for four 26-minute defrost cycles per day (2
AM,
8
AM, 2 PM, and 8 PM). Depending on local
conditions, it may be necessary to change the
frequency or duration of defrost cycles.
If the power supply is interrupted, the defrost
timer must be reset to the correct time of day.
