E. Defrost
1. Refrigerators
Refrigerators use an off-cycle, time-initiated defrost and defrost once every 2 hours.
When the defrost thermistor warms to44°F (6.6°C), defrost terminates. The minimum
defrost time is 20 minutes and the maximum defrost time is 1 hour. Cabinet temperature
is displayed during defrost.
2. Freezers
Freezers use a heated, temperature/time-initiated defrost. Once the defrost thermistor
cools to 32°F (0°C), the 4-hour cumulative compressor run timer starts. When the 4-hour
cumulative compressor run timer terminates, defrost begins. Cabinet temperature is not
displayed during defrost; "dEF" is displayed in its place. When the defrost thermistor
warms to 59°F (15°C), defrost terminates. A 3-minute compressor delay timer, a 7-minute
evaporator fan motor delay timer, and an 18-minute temperature display delay timer start.
As the delay timers terminate, the related components energize. Note that the 7-minute
evaporator fan motor delay time is a maximum; if the defrost thermistor cools to 25°F
(-3.9°C) before the 7-minute evaporator fan motor delay timer terminates, the evaporator
fan motor will energize. Freezers have a minimum defrost interval of 4 hours. The
minimum defrost time is 5 minutes and the maximum defrost time is 1 hour.

H. Safety Devices
1. Compressor External or Internal Overload
If combined temperature/amperage value is above the limit specied 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 specications, 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.
• Cabinet too tightly packed or cabinet air inlet/outlet blocked. Allow some space between
items to ensure good air ow.
• 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.
