General

Heated Zone Merchandisers are setup at the factory for energy-saving, automatic operation (Auto Mode). Refer to "Factory Setpoints" in the SPECIFICATIONS section for factory setpoint information. Use the following information and procedures to operate a Heated Zone Merchandiser.

Read all safety messages in the IMPORTANT SAFETY INFORMATION section before operating this equipment.

Do not place food product directly onto hardcoat surface. Food product must be wrapped, boxed, or on a food pan.

NOTICE

Do not slide pans across hardcoat surface, use rough-bottomed pans, or drop anything on hardcoat surface. Scratching may occur. Damage to hardcoat surface caused by misuse is not covered under warranty.

Theory of Operation

The Heated Zone Merchandiser is designed for efficient and environmentally-friendly operation by heating specific "zones" only when product is present. The operation of the Heated Zone Merchandiser is controlled by a series of optical sensors and the LCD controller. The sensors are located along the sides of each hardcoat shelf. Larger units have additional sensors located in zone dividers that separate each shelf into multiple overhead heat zones.

For all sizes of units, each hardcoat shelf is equipped with separate front and rear heating elements. These two elements operate independently in Auto Mode.

The number of overhead ribbon heating elements is determined by the size of the unit. The overhead elements above each hardcoat shelf are considered individual heat zones. This means that the number of zones on each shelf is either two, four, or six—depending on the size of the unit. Each overhead element operates independently in Auto Mode

NOTE: Each shelf on a Heated Zone Merchandiser can be set to a different operating mode.

Auto Mode Operation

At startup in Auto Mode operation, all shelf heating elements and overhead heating elements in an empty Heated Zone Merchandiser will be in Stand-By. The front and rear shelf elements will heat at their Stand-By power percentage to the setpoint temperature. All overhead elements remain off. When product is placed on a shelf, the optical sensors signal the LCD controller, and the controller activates the appropriate shelf elements and overhead elements. Each of the shelf elements affected by the placement of product will heat at full wattage to the setpoint temperature. Each of the overhead elements affected by the placement of product will heat at its setpoint power percentage. All affected elements will remain activated until all product is removed from the "zone." Anytime a zone is emptied of product, the zone will return to Stand-By.

On Mode Operation

At startup in On Mode operation, all shelf heating elements will heat at full wattage to the setpoint temperature, and all overhead heating elements will heat at their setpoint power percentage. All shelf elements will remain at full wattage and all overhead elements will remain at their setpoint power percentage the entire time the unit is on.
