• 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 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. Otherwise, items may freeze up and crack or
break causing a risk of injury or contamination of other food.
Additional Information for Prep Table Models
• The entire rail must always be covered by rail dividers and pans (1/6 size, up to
6"(15cm)deep). Otherwise, the appliance will not cool properly.
• Use only 1/6 size pans up to 6"(15cm) deep. Do not use damaged 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.

F. Safety Devices
1. Compressor External or Internal Protector
If combined temperature/amperage value is above the limit specied 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.
G. 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:
• Doors/drawers opened too often.
• Doors/drawers left open. Close.
• Cabinet too tightly packed or air inlets/outlets 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 control setting not cold enough. Adjust to a colder setting. The warmest
setting is 1 and the coldest setting is 9.
• Prep Table Refrigerators and Undercounter and Worktop Freezers: Appliance in defrost
cycle. The cabinet temperature may rise temporarily during the defrost cycle, but this
will not affect the food inside.
Additional Information for Prep Table Models
• Pans and rail dividers not in place. The entire rail must always be covered by rail
dividers and pans (1/6 size, up to 6"(15cm)deep) or the rail will not cool properly.
• Warm or hot ingredients inside. Only load ingredients that have been pre-chilled to 37°F
(3°C) or less.
