Manufacturer’s Introduction
The Duke Product Holding Cabinet was developed
in response to need for extended food-holding
capabilities to provide consistently high, “just
cooked” food quality.
The Duke Product Holding Cabinet utilizes Duke’s
patented “heat sink” holding technology that
provides even heat distribution to food pans
through the bottom and sides. This allows precooked 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
Cabinet 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
Cabinet allows single temperature operation for all
existing product groups. This 190° F approved
temperature is preset at the factory. This reduces
the likelihood of inconsistent performance between
locations.
The Duke Product Holding Cabinet was also
designed to rethermalize food product.
A
thermostat setting of 200° F minimum is required
for rethermalization. See instructions on page 7 for
thermostat adjustment.
NOTE: Only qualified
service persons should modify control temperature
presets.

Stacking Units
The FWM3-23 Product Holding Cabinet is designed to allow limited stacking capabilities. This section outlines
how to safely stack the holding cabinet.
Step
1
Step
2
Remove the base pan from all holding cabinets, except for
bottom unit, that are to be stacked. The pan is held in
place by two screws on the bottom of the unit.
Place bottom unit into position then stack the next unit on top. The top
of the lower holding cabinet rests inside of the base of the upper unit.
WARNING!
TIP HAZARD! Do not exceed 3 holding
cabinets per stack. Do not place holding
cabinet stacks on surfaces that may easily
tip over.

Periodic Maintenance, Checklist And Cleaning Guide
DAILY
Opening Checklist
1. Ensure proper Pan Covers are inserted into the correct locations for fried and broiled products.
2. Place the Power Switch, located on the front of the Product Holding Cabinet, to the ON position.
3. Ensure both top and bottom HEAT Lights are illuminated.
4. Allow the Product Holding Cabinet to heat for at least 20 min. or until the HEAT Lights cycle off.
Operation Instructions/Adjustments
1. If the SERVICE Light illuminates during operation of the Product Holding Cabinet, discontinue
use of the affected shelf until the module is serviced.
2. Operate using Menu Bar as outlined in the Menu Scoreboard Operators Manual.
Closing Checklist
1. Turn power switch OFF.
2. Remove all pans and pan covers.
3. Allow to cool for approximately 30 minutes.
4. Clean Product Holding Cabinet as outline in the Daily Cleaning Instructions.
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. Ensure all soap is rinsed from
plastic pans and pan covers.
Caution!
Electrical shock hazard. Do not wash with water jet or hose.
Do not use caustic cleaners, acids, ammonia products or abrasive cleaners or
abrasive cloths. These can damage the stainless steel and plastic surfaces.
!Warning!
Bottom and sides of warmer wells are very hot and cool slowly.

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 Service Light is located on the front of the control next to the heat light (see Figure 3). It provides an
indication to alert the operator to failures in the heater circuit. When a Service Light is on, the affected shelf
should not be used until the cause of the fault is corrected by a qualified service technician. The fault
conditions that could cause the control to turn the service light on are as follows:
1.
Over – Temperature Fault - An overtemperature fault occurs when the control
senses that the shelf temperature is higher
than the specified factory preset temperature.
This occurs when the power is not removed
from the heating element after the shelf has
achieved the preset temperature, causing the
control to turn on the service light. The
auxiliary thermostat prevents the temperature
from exceeding safe levels by regulating the
temperature to a maximum of 250° F.
2. Under – Temperature Fault - An undertemperature fault occurs when the control
senses that the shelf temperature is lower than
the specified factory preset temperature for
more than 30 minutes continuously. This
occurs when heating element circuit opens or
the RTD Feedback signal is faulty, causing the
control to turn on the service light.
Figure 3
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.
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 (see Figure 3). 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 from the set
point.

Control Programming
The electronic temperature control is pre-set at the factory to maintain the temperature at the bottom
center of the pan cavity at 190° F +/- 5° F. This temperature is the result of many hours of laboratory
food testing. There are no operator temperature adjustments that can be made. Because the electronic
control uses a platinum type RTD sensor, routine calibration is not required.
!DANGER!
LIVE ELECTRICAL COMPONENTS.
ONLY QUALIFIED SERVICE PERSONS SHOULD MODIFY CONTROL
TEMPERATURE PRESETS.
Temperature Programming
1. Remove cover from control side of the Holding
Cabinet and turn the Holding Cabinet on.
2. Locate the pushbutton S1 and S2 on the rear of
the control. (see Figure 4.1)
3. Press and hold S1 until any LED on the rear of
the control illuminates. (approximately 5
seconds)
4. Observe the front of the control (Figure 4.2).
Press and release S1 on the back of the control
until the desired light on the front of the control
flashes. (see Table 1)
FIGURE 4.1
Figure 4.1
NOTE: To comply with NSF sanitation requirements,
do not set the control preset temperature
below 190° F.
5. Press and release S2 until the sum of the LED
values illuminated on the rear of the board match
the desired pre-set temperature.
6. Repeat steps 4 and 5 for each pre-set
temperature then press and hold S1 until no LED
on the rear of the control is illuminated and the
lights on the front of the board no longer flash.
7. Replace cover on control side of the Holding
Cabinet.
