I. Cooling Performance
Be sure the unit 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.
• Too packed with food or cabinet air inlet/outlet blocked. Allow some space between items/
containers to ensure good air flow.
• 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.
• Cabinet temperature setting too high. Readjust it to a lower temperature.
• Unit in defrost process. 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:
• Perimeter frame heater off. Move the perimeter frame heater switch, located on the
control box, to the "ON" position (red marking visible).
• Door(s) left open, close.
• Ambient humidity too high. In high humidity areas it may be necessary to wipe off the
cabinet frame occasionally.
