Installation and Operation of Product Holding Cabinets
MANUFACTURER’S INTRODUCTION
The Duke Product Holding Unit was developed for extended food-holding capabilities to provide consistently high, “just cooked” food quality.
The Duke Product Holding Unit utilizes Duke’s patented “heat sink” holding technology that provides even heat distribution to food pans through the bottom and sides. This allows pre-cooked foods to be held for extended periods without noticeable degradation of quality, reducing food scrap/waste.
The self contained, individually formed, sealed compartments of the Duke Product Holding Unit eliminates food odor and taste transfer. Because the compartments are sealed and formed to the shape of the pan, no disassembly is required for cleaning and product changes.
The unique design of the Duke Product Holding Unit allows single temperature operation for all existing product groups. This 180°F(82°C) approved temperature is preset at the factory. This reduces the likelihood of inconsistent performance between restaurant locations.
The Duke Product Holding Cabinet was also designed to rethermalize food product. Athermostat setting of 180°F(82°C) minimum is required for re-thermalization. To comply with sanitation requirements do not set the temperature control lower than 180°F(82°C) or equivalent.
: Only qualified service persons should modify control temperature presets.
SERIAL NUMBER LOCATION
The Serial Number Data Label is located on the rear of the unit, above the power cord connection. Refer to the Serial Number Data Label for proper electrical requirements. The serial number and model number are required when communicating with the Duke Service Department.
