(2) Defrost for Freezer
This unit uses a time-initiated heated defrost. It is preset at the factory to defrost 6 times
per day for general conditions. However, if it is determined that this interval does not suit
the actual conditions the unit is exposed to, the interval can be changed. To change, see
"(3) Defrost Frequency Adjustment" below. Contact the HOSHIZAKI Technical Support
Department for recommendations. Please note that since the defrost is a heated defrost,
it will have a tendency to raise cabinet temperature. Defrost termination temperature is
100°F (37.8°C).
During freezer defrost, the cabinet temperature is not displayed, "dEF" is displayed in its
place.
