WARNING
• Storage of foods should follow all local codes and regulations.
• 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.
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 minimum off-time and on-time for the compressor.
Refrigerator: 2-min.
Freezer: 3.5-min.
Note: Time may vary with compressor overload.
