The Roundup Display Case attractively displays
your food and maintains it at ready-to-eat temperature. A convection fan (some models) circulates heat
throughout the entire display cabinet while a digital
temperature control maintains a constant temperature.
Humidity water trays (some models) extend food holding times by reducing moisture loss.
Models DCH-100, DCH-200, and DCH-300 are primarily for meats and poultry products.
Models DCH-120, DCH-220, and DCH-320 are primarily designed for bread products.

Operations and Programming
IMPORTANT: Models DCH-120/220/320 have an
adjustable temperature range of 100-165° F (38-74°
C). Since the temperature can be set below 150° F
(65° C), which is below the safe holding temperature for some foods, only NON-MEAT products
should be held in these units. Models DCH-100/
200/300 have an adjustable temperature range of
150-165° F (66-74° C).
NOTE: The Setpoint temperature is the desired
cabinet temperature setting. When the Temp UP
button is pressed and held (and provided that the
unit is up to temperature), the actual cabinet temperature is displayed. When the button is released,
the Setpoint temperature is displayed.
For units ONLY equipped with Water Tray(s) and
diffuser(s) (Figure 2):

water to the Water Trays. If a humid environment is desired, add water to the Water Trays as
shown in Figure 2. If more humidity is desired,
remove the Diffusers from the Water Trays.
NOTE: Fogging/Condensation of the glass may
occur if the Water Trays contain too much water
and/or the Diffusers are not present in the water
trays. Units equipped with a Crumb Tray (Figure 1)
are designed to operate WITHOUT water.
1. Turn the unit ON. The display will flash “LO” to
indicate that the unit is heating up. After 20-30
minutes (when the unit is up to temperature), the
display will show the setpoint temperature.
2. To adjust the setpoint temperature, press and
hold the Temp Up and Temp Down buttons until
the display begins to flash. Release the buttons.
Then, press the Temp Up or Temp Down buttons to raise or lower the setpoint temperature.
Release when the display shows the desired temperature.

up firmly and slide bottom of door into bottom
inside track. Install other door into outside tracks
the same way.
FRONT GLASS PANEL REPLACEMENT
CAUTION
Front glass panel replacement should be performed by two people to prevent damage to the
glass.
1. Turn the unit OFF, unplug the power cord from
the electrical outlet, and allow the unit to cool to
room temperature before proceeding.
2. Loosen the thumbscrew securing each Top Glass
Retainer Assembly. Slide the retainer up and to
the rear (Figure 8).
3. Tilt the Front Glass Panel Assembly forward on
the Hinge Plate and remove the panel from the
unit.
4. To reinstall, be sure the Front Glass Panel
Assembly is fully seated in the Hinge Plate.
Then, tilt the assembly fully towards the rear and
secure it to the Top Glass Retainer Assembly
using the thumb screws.
SIDE GLASS REPLACEMENT
1. Turn the unit OFF, unplug the power cord from
the electrical outlet, and allow the unit to cool to
room temperature before proceeding.
2. Remove the thumbscrews securing each Top
Glass Retainer Assembly. Slide the retainer up
and to the rear.
3. Tilt the Front Glass Panel Assembly forward on
the Hinge Plate and remove the assembly from
the unit.
4. Remove each Top Cap Assembly (Figure 8).
Next, lift the Side Glass Panel up and forward to
remove it from the glass clips.
6. To reinstall, position the Side Glass Panel into
glass clips. Push fully rearward and position the
Nylon Stoppers according to Figure 8. Reinstall
the front glass panel assembly (Figure 8).
(continued)
7. Secure with the Top Cap Assembly and Top
Glass Retainer Assembly using the thumbscrews.
NOTE: The Display Panel
Assembly is held in place
by magnetic strips. To
remove, carefully pry the
assembly from its place
using a flat-blade screw
driver or similar tool.

MAINTENANCE (continued)
Technical Theory of Operation
When the Rocker Switch (power On/Off) is set to ON,
line voltage flows to the primary side of the Step Down
Transformer. The Transformer’s secondary side supplies 12-14 VAC to terminals T1 and T2 on the Control
Board.
Once powered, and provided that the Cabinet temperature is below the setpoint temperature, the Control
Board, in conjunction with a 100K ohm Thermistor, calls
for heat by supplying 15-20 VDC to terminals 3 (+) and
4 (-) on the Solid State Relay. Once powered, the Solid
State relay closes terminals 1 and 2, which allows line
voltage to flow to the heater(s).
As the Cabinet Temperature begins to increase, the
Thermistor monitors the Cabinet Temperature and
its ohms begin to decrease. Once the Cabinet temperature approaches the setpoint temperature, the
Thermistor’s ohms are relayed over to the Control
Board.
The Control Board receives the ohms and proceeds to
remove the 15 - 20 VDC to the Solid State Relay since
the Heating Circuit has now become satisfied. The
relay terminals 1 and 2 open and the heater(s) stop
heating. The heating circuit will cycle on and off as
needed. The control board has the ability to display
several codes (see the section titled Display Codes in
the Maintenance section of this manual).
On some models, the Heated air is circulated by one
or two blower motors, while other models do not use
blower motors. Some models use water trays while
other models use a crumb tray.
NOTE: Crumb Trays (Figure 1) must NOT contain
water.
When the Water Trays (Figure 1) are filled with water,
the heat radiated by the heaters cause the water
to evaporate, which gradually adds humidity to the
Cabinet (see the Operation section of this manual).
NOTE: Water Trays use a diffuser (Figure 1). The
purpose of a diffuser is to shield away excessive
heat. This will allow the water to evaporate at a
slower rate resulting in a reduction of humidity in
the cabinet. On 120 volt units, the front display
panel is illuminated by 4, 6, or 8 120V, 10 watt, candescent bulbs that are wired in parallel (see the
Wiring Diagram section of this manual for 120 Volt
units).
NOTE: The 220/240 volt units also use the 120 volt
bulbs, but the bulbs are wired in series and in two
bulb circuits (see the Wiring Diagram section of this
manual for 220/240 volt units).
The internal cabinet area is illuminated by 1 or 2 120
volt, 100 watt halogen bulb(s). On 120 volt units, each
halogen bulb is wired in series with a 10 ohm, 50 watt
resistor (see the Wiring Diagram section of this manual
for 120 volt units). The purpose of the resistors is to
allow for a voltage drop. The voltage drop allows the
halogen bulb’s brightness to be slightly reduced.
NOTE: On 220/240 units, the Halogen Bulbs and
Resistors are all wired in series with one another.
See the Wiring Diagram for 220/240 volt units.

Display Codes
This section describes the different display codes and
their meanings.
DISPLAY CABINET HEATED
“LO” flashes during the initial warm up period. The unit
continues to display this code until the unit reaches the
setpoint temperature. When the unit reaches the setpoint temperature, it displays the setpoint temperature.
This figure shows an example setpoint temperature of
150° F displayed on the console.
“HI” flashes if the actual cabinet temperature exceeds
the setpoint temperature or if the thermistor has shorted.
NOTE: The thermistor should be 100k ohm +/- 2% at
room temperature.
“OPEN” flashes if the thermistor is OPEN or disconnected. The unit will not call for heat.
NOTE: The thermistor should be 100k ohms +/- 2%
at room temperature.
“PO” In 120 VAC units, this code flashes if the supply
voltage is below 100 VAC or above 135 VAC. In 220/
240 VAC units, this code flashes if the supply voltage is
below 190 VAC or above 265 VAC.
NOTE: If voltage is within normal ranges, then the
Control Board is faulty.
P/N 1010772 Rev. C 01/06
To reset a unit in this state, the supply voltage must be
within acceptable limits and the unit must be turned off
for a few seconds and then turned back on.
