1. Automatic Defrost
Defrost is a time/temperature initiated, temperature terminated heated defrost.
• Defrost Initiation: When the appliance is plugged in, the 6 hr. defrost timer
starts. Once the 6 hr. defrost timer terminates, the rail control module checks the
defrost thermistor for defrost initiation temperature of 41°F (5°C) or below. If the
defrost thermistor is not at or below 41°F (5°C), the rail control module continues
in the cooling mode. If defrost thermistor is at or below 41°F (5°C), defrost
initiates. Ifenergized, the compressor, rail fan motor(s), and cabinet fan motor(s)
de-energize. Defrost heater energizes, cabinet display cooling icon turns off, defrost
icon turns on, and "dEF" is displayed.
Note: To manually reset the 6-hr. defrost timer, initiate a manual defrost then
terminate using the same procedure as initiating a manual defrost.
See "II.E.2. Manual Defrost" below.
• Cabinet Display During Defrost: "dEF" is displayed. The cooling (cabinet fan
motor) icon turns off and the defrost icon turns on. The defrost icon and "dEF" are
displayed for 30 min. Note: Cabinet fan motor(s) are locked out during the 30-min.
defrost icon and "dEF" display time. The compressor and rail fan motor(s) are
controlled separately by the rail thermistor and rail control module.
• Defrost Termination: After the 5-min. minimum defrost timer terminates and the
defrost thermistor warms to 41°F (5°C), the rail control module terminates defrost
and resets the 6 hr. defrost timer. Note: Cabinet display is not affected by the rail
defrost thermistor temperature and continues to show "dEF" until the 30-min. "dEF"
display timer terminates.
• The compressor and rail fan motor(s) energize 3-min. after defrost termination
(drip time). Note that the 3 min. rail fan motor delay time is a maximum; if the
defrost thermistor cools to 36°F (2.2°C) before the 3 min. rail fan motor delay timer
terminates, the rail fan motor(s) energize.

G. Food Storage
WARNING
• The appliance is designed only for temporary 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 air inlets or outlets, otherwise cooling performance may be reduced.
• Do not tightly pack the cabinet. Allow some space between items to ensure good
air ow. Also allow space between items and interior surfaces.
• Do not put warm or hot foods in the cabinet. Let them cool rst, or they will raise
the cabinet temperature and could deteriorate other foods in the cabinet or
overload the appliance.
• All foods in the cabinet should be wrapped in plastic lm 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 air outlets in the cabinet. Otherwise, items may freeze up
and crack or break causing a risk of injury or contamination of other food.
• The entire rail must always be covered by rail dividers and pans. Otherwise, the
appliance will not cool properly. Use only pans up to 6"(15cm) deep. Do not use
damaged rail dividers or pans.
• Ingredients must be pre-chilled to 37°F (3°C) or less before placing in rail.
• Keep the rail cover closed when not actively preparing food.
• The rail is for keeping ingredients cool while preparing food. If not actively
preparing food for a long period such as overnight, seal pans with plastic
wrap in addition to closing the rail cover. Depending on conditions, the cabinet
temperature setting may need to be adjusted to prevent items from freezing.
Alternatively, seal ingredients and store them in a refrigerator or freezer.
H. Safety Devices
1. Compressor External Protector
If combined temperature/amperage value is above the limit specied by the
compressor manufacturer, the compressor protector operates independently to turn
off the compressor. The compressor protector 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.
