(2) Defrost for Freezer
This appliance 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 conditions, the interval can be changed. To change, see "(3) Defrost
Frequency Adjustment" below. Contact the Hoshizaki Technical Support Department for
recommendations. Note that since the defrost is heated, it will have a tendency to raise
cabinet temperature. Defrost termination temperature is 100°F (38°C).
During freezer defrost, the cabinet temperature is not displayed, "dEF" is displayed in its
place.
(3) Defrost Frequency Adjustment
1) Press and hold the up/down arrows simultaneously for 3 seconds. Press "ENTER" until
"dF" is displayed.
2) To change the time-initiated defrost frequency, press the up/down arrows until the
desired value is displayed. For refrigerators (control board revision 23 and later), the
defrost frequency is adjustable between 0 and 12 defrosts per 24 hours. For freezers,
the defrost frequency is adjustable between 1 and 12 defrosts per 24 hours. The factory
default for refrigerators is 0 and the factory default for freezers is 6.
3) To save the value, press "ENTER" repeatedly until you have cycled through the menu
and the appliance returns to the normal display mode. If you do not cycle through the
menu and no button is pressed in 15 seconds, the display will return to normal and the
defrost frequency will remain unchanged.
Note: The change in the defrost setting will take effect after the next defrost based on
the previous setting. If it is desired that this change in interval timing take effect
immediately, turn the appliance off and back on. The next time-initiated defrost
will take effect "x" hours after power is resupplied. For example, if the setting is
dF 6, x=4 and the next defrost will take place 4 hours from the time that power is
applied.
Primary defrost termination is controlled by the defrost thermistor. However, two
additional safeties are also present:
• Time Termination - 1 hour maximum
• Temperature Termination - Measured by a separate device that is in-line with the
heaters and independent of the control board
c) Temperature Display Scale (°F or °C)
To change the display scale, follow the steps below.
1) Press and hold the up/down arrows simultaneously for 3 seconds. Press "ENTER" until
"F" or "C" temperature display scale is displayed.
2) To change the temperature display, press the up/down arrows until the desired scale is
displayed. The factory default is "F".
3) Press "ENTER" to save the value and return to normal display mode. If you do not press
"ENTER" and no button is pressed in 15 seconds, the display will return to normal and
the temperature display scale will remain unchanged.
