Installation and Operation of HSHU

INTRODUCTION

The Duke HSHU was developed for extended food-holding capabilities to provide consistently high, “just cooked” food quality.

The HSHU 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 HSHU 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 or product changes.

The unique design of the HSHU allows multiple temperature operation for all existing product groups.

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 Dept.
