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 qualied service persons should modify control temperature presets.

(no product).
OPERATION INSTRUCTIONS AND
ADJUSTMENTS
1. If the menu bars display temperature at any time
during operation of the Product Holding Cabinet,
discontinue use of the affected shelf until the cabinet
is serviced.
2. Refer to the KEYPAD PROGRAMMING section
of the manual for instructions on using and
programming the keypad.
CLOSING CHECKLIST
1. Place the Power Switch in its OFF position.
2. Remove all pans and pan covers.
3. Allow the cabinet to cool for approximately
30 minutes.
4. Refer to the CLEANING INSTRUCTIONS section
of the manual for proper care and cleaning of the
cabinet.
: Electrical Shock Hazard, unplug
the cabinet before cleaning it.
: Do not wash with water jet
or hose.
: Bottom and sides of warmer
wells are very hot and cool slowly.
CAUTION: Do not use caustic cleaners, acids,
ammonia 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
lm that shields against corrosion. If the lm remains
intact, the stainless steel will remain intact. However,
if the lm 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,
les, 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 chloride-
containing cleaning solutions, which will break
down the protective lm.
CAUTION: Never rub in a circular motion.
CAUTION: Never leave any food products or

19
Installation and Operation of Product Holding Cabinets
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 lm.
Preserve the life of stainless steel with a regular
application of a high quality stainless steel polishing
cleaner as a nal 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 lm 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.
