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. A thermostat 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.
Notice: 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 erial Number Data Label for proper electrical requirements. The serial number and model number are required when communicating with the Duke Service Department.

WARNINGS : Do not wash with water jet or hose.
WARNINGS : Bottom and sides of warmer wells are very hot and cool slowly.
CAUTION: Do not use caustic cleaners, acids, mmonia products or abrasive cleaners or abrasive cloths. These can damage the stainless steel and plastic surfaces.
CLEANING INSTRUCTIONS

1. Wipe down the interior and exterior of the Product Holding Cabinet with warm water and mild detergent using a soft cloth. Do not use excessive amounts of water.
2. Clean pans and pan covers using mild detergent and warm water.
3. Ensure all soap is rinsed from plastic pans and pan covers.

STAINLESS STEEL CARE

Cleaning
Stainless steel contains 70-80% iron, which will rust if not properly maintained. It also contains 12-30% chromium, which forms an invisible passive, protective film that shields against corrosion. If the film remains intact, the stainless steel will remain intact. However, if the film is damaged, the stainless steel can break down and rust. To prevent stainless steel breakdown, follow these steps:
CAUTION: Never use any metal tools. Scrapers, files, wire brushes or scouring pads (except for stainless steel scouring pads) will mar the surface.
CAUTION: Never use steel wool, which will leave behind particles that rust.
CAUTION: Never use acid-based or chloridecontaining cleaning solutions, which will break down the protective film.
CAUTION: Never rub in a circular motion.
CAUTION: Never leave any food products or salt on the surface. Many foods are acidic. Salt contains chloride.
For routine cleaning, use warm water, mild soap or detergent and a sponge or soft cloth.
For heavy-duty cleaning, use warm water, a degreaser and a plastic, stainless steel or Scotch-Brite pad. Always rinse thoroughly. Always rub gently in the direction of the steel grain.
Preserving & Restoring
Special stainless steel polishing cleaners can preserve and restore the protective film.
Preserve the life of stainless steel with a regular application of a high quality stainless steel polishing cleaner as a final step to daily cleaning.
If signs of breakdown appear, restore the stainless steel surface. First, thoroughly clean, rinse and dry the surface. Then, on a daily basis, apply a high-quality stainless steel polish according to manufacturer’s instructions.
Heat Tint
Darkened areas, called heat tint, may appear on stainless steel exposed to excessive heat, which causes the protective film to thicken. It is unsightly but is not a sign of permanent damage.
To remove heat tint, follow the routine cleaning procedure. Stubborn heat tint will require heavy-duty cleaning.
To reduce heat tint, limit the exposure of equipment to excessive heat.

TROUBLESHOOTING

There are no user serviceable parts on the Duke Product Holding Cabinet. If a malfunction occurs, ensure unit is plugged in then check all switches and circuit breakers. If the malfunction still exists, contact your Duke Manufacturing Company authorized service agent or call 1-800-735-3853.
Electronic Control Fault Indications The keypad display provides an indication to alert the perator to failures in the heater circuit. The possible fault conditions are as follows:

1. Over-Temperature Fault – An over-temperature fault occurs when the control senses that the shelf temperature is higher than the specified factory preset temperature for thirty minutes. This occurs when the power is not removed from the heating element after the shelf has achieved the preset temperature. The auxiliary thermostat prevents the temperature from exceeding safe levels by regulating the temperature to a maximum of 250°F(121.1°C). If this occurs, “HI” will appear on the keypad; the affected unit should not be used until the cause of the fault is corrected by a qualified service technician.
2.  Under-Temperature Fault – An under-temperature fault occurs when the control senses that the shelf temperature is lower than the specified factory preset temperature for more than thirty minutes continuously. This occurs when heating element circuit opens or the RTD Feedback signal is faulty. If this occurs, “LO” will appear on the keypad and the affected unit should not be used until the cause of the fault is corrected by a qualified service technician.
3. Sensor Fault – If it any time during normal operation “SENS” is displayed on the keypad: discontinue operation and contact qualified service technician.

Temperature Check Procedure

1. A digital temperature meter that has been calibrated must be used to get an accurate temperature reading. Use a thermocouple surface temperature probe to measure temperatures.

2.  No pans should be in wells during the pre-heat and temperature check. Pre-heat the warmer for 30 minutes before taking any temperature readings.
   Do not take readings unless the cavity has been empty for 30 minutes. This will allow the temperature to stabilize and will prevent false readings.
   NOTE: During normal operation the temperature may drop below the preset, due to environmental conditions. When this occurs the actual temperature will be displayed. This condition will be momentary and normal operation will resume shortly. If this should occur frequently or for long periods of time, the affected unit should not be used and you should contact the service hotline.

3. The warmer cavity should be cleaned and empty before the temperature is checked. Avoid any air drafts that might flow through the cavity.

4. Locate the surface temperature probe on the bottom of the first cavity in the geometric center. The first cavity is the one closest to the control panel. Make sure the probe is making good contact with the surface while taking readings.

5. All temperature controls exhibit a swing in temperature as the control cycles on and off while regulating to the set point. The correct calibration temperature is the average of several readings taken over a period of 20 minutes after the warmer has been pre-heated. The average temperature should be ± 5°F(± 2.5°C) from the set point.

Service Hot-Line
Check the display for fault messages. Perform the Temperature Check Procedure in this manual. Make note of the findings. Please, have this data handy before calling the Duke troubleshooting Hot Line listed above. For optimum support, please be near the suspect units with a cordless phone, if available, when calling our Technicians.
