• Ne pas perforer la tubulure contenant le frigorigène. Risque de feu ou d'explosion si la
tubulure contenant le frigorigène est perforée; suivre les instructions de manutention
avec soin.
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).
3. Manual Defrost
To initiate a manual defrost, press the manual defrost button, defrost begins.

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.
