2. Adjusting the Temperature Setpoint
The temperature setpoint is the value for the average cabinet temperature. The
temperature differential for the compressor to turn on and off is ±3°F (±1.7°C) of the
temperature setpoint. For example, for a refrigerator temperature setpoint of 36°F (2°C),
the compressor comes on at 39°F (3.7°C), and the compressor goes off at 33°F (0.3°C).
If necessary, adjust the temperature setpoint temperature as follows:
1) To change the temperature setpoint, press and release the up or down button.
The current temperature setpoint appears. Press the up or down button until the
desired value is displayed. After a few seconds, the display returns to the current
cabinet temperature and the temperature setpoint is saved. NOTICE! Do not adjust
the temperature setpoint more than 2°F (1°C) at a time. Allow the temperature to
stabilize for a minimum of 8 hours before making further temperature setpoint
adjustments.
• For refrigerators, the temperature setpoint is adjustable between 31°F and 52°F
(-0.5°C and 11°C). The factory default is 38°F (3°C).
• For freezers, the temperature setpoint is adjustable between -10°F and +12°F (‑24°C
and -11°C). The factory default is -2°F (-19°C).

1. Refrigerators
Refrigerators use a time-initiated, off-cycle defrost. Defrost occurs when either the
2-hr. cumulative compressor run timer terminates or the 2-hr. continuous compressor run
timer terminates. When either the 2-hr. cumulative compressor run timer or the
2-hr. continuous compressor run timer terminates, defrost begins. The 5-min. minimum
defrost timer and the 1-hr. maximum defrost timer starts. If energized, the compressor
de‑energizes and the evaporator fan motor continues. Cabinet temperature is not
displayed during defrost; "dEF" is displayed in its place along with defrost icon. After
the 5-min. minimum defrost timer terminates and the defrost thermistor warms to 44°F
(6.6°C), defrost terminates. The defrost icon turns off and the compressor energizes.
"dEF" is displayed during defrost and continues for 15 min. after defrost termination.
Once the 15-min. "dEF" display timer terminates, cabinet temperature returns to the
display. Note: If the defrost thermistor is above 50°F (10°C) the evaporator fan motor
de‑energizes until the defrost thermistor drops to 49°F (9°C).
2. Freezers
Freezers use a time-initiated, heated defrost. Defrost occurs when either the
5‑hr. cumulative compressor run timer terminates or the 4-hr continuous compressor
run timer terminates. When either the 5 hr. cumulative compressor run timer or the
4-hr continuous run timer terminates, defrost begins. The 5-min. minimum defrost timer
and the 1-hr. maximum defrost timer starts. If energized, the compressor and evaporator
fan motor de‑energizes. Cabinet temperature is not displayed during defrost; "dEF"
is displayed in its place along with the defrost icon. After the 5-min. minimum defrost
timer terminates and the defrost thermistor warms to 77°F (25°C), defrost terminates
(defrost heater de-energizes). A 3-min. compressor delay timer starts. Once the 3-min.
compressor delay timer terminates, the compressor energizes and a 4-min. evaporator
fan motor delay timer (drip time) starts. Once the 4-min. evaporator fan motor delay timer
(drip time) terminates, the evaporator fan motor energizes, the defrost icon turns off, and
the 15‑min. temperature display delay timer starts. Once the 15-min. temperature display
delay timer terminates, cabinet temperature is displayed. Note that the 4-min. evaporator
fan motor delay time is a maximum; if the defrost thermistor cools to 15°F (-9.5°C) before
the 4-min. evaporator fan motor delay timer terminates, the evaporator fan motor will
energize. Note: If the defrost thermistor is above 32°F (0°C) the evaporator fan motor
de‑energizes until the defrost thermistor drops to 29°F (-0.5°C).

F. Food Storage
WARNING
• This appliance is designed only for storage of food. Employ sanitary methods. Use
for any other purposes (for example, storage of chemicals or medical supplies
such as vaccine and serum) could cause deterioration of stored items.
• Do not block the cabinet air inlet or outlet, otherwise cooling performance may be
reduced.
• Do not tightly pack the cabinet. Allow some space between items to ensure good
air flow. Also allow space between items and interior surfaces.
• Do not place any product on the floor of the cabinet. All product must be placed on
properly installed shelves.
• Do not put warm or hot foods in the cabinet. Let them cool first, or they will raise
the cabinet temperature and could deteriorate other foods in the cabinet or
overload the appliance.
• All foods should be wrapped in plastic film or stored in sealed containers.
Otherwise foods may dry up, pass their smells onto other foods, cause frost
to develop, result in poor appliance performance, or increase the likelihood of
cross‑contamination. Certain dressings and food ingredients, if not stored in
sealed containers, may accelerate corrosion of the evaporator, resulting in failure.
• Do not store items near the air outlet. They might freeze up and crack or break
causing a risk of injury or contamination of other food.

H. Safety Devices
1. Compressor External or Internal Overload
If combined temperature/amperage value is above the limit specified by the
compressor manufacturer, the compressor overload operates independently to turn
off the compressor. The compressor overload de-energizes the compressor until the
temperature/amperage value returns to an acceptable level.
2. Short-Cycle Protection
There is a 2-minute minimum off-time and on-time for the compressor.
Note: Time may vary with compressor overload or high-pressure switch activation.
3. High-Pressure Switch
If pressure on the high-side of the appliance exceeds Hoshizaki specifications, the
high‑pressure switch activates and interrupts the compressor circuit, de‑energizing the
compressor until the pressure returns to an acceptable level.
I. Cooling Performance
Be sure the appliance is properly installed and located for optimum cooling performance.
If cooling performance is not at its optimum level, check the following items:
• Door(s) opened too often.
• Door(s) left open. Close.
• Dirty air filter and/or condenser. Clean.
• Cabinet too tightly packed or cabinet air inlet/outlet blocked. Allow some space between
items to ensure good air flow.
• Warm or hot foods inside. Take them out until they cool down more.
• Ambient temperature too high. Avoid installation near high heat producing equipment or
exposure to direct sunlight.
• Temperature setpoint too high. Readjust it to a lower temperature.
• Appliance in defrost cycle. The cabinet temperature may rise temporarily during the
defrost cycle, but this will not affect the food inside.
J. Cabinet Condensation
In the event condensation develops on the cabinet exterior, check the following items:
• Door(s) left open. Close.
• Ambient humidity too high. In high humidity areas it may be necessary to wipe off the
cabinet frame occasionally.
