RECEIVING INSPECTION
DO NOT STORE THE VENDER OUTSIDE.
Upon receipt, inspect the vender for any shipping
damage. If there is any damage, have the delivery
driver note the damage on the bill of lading and notify
Dixie-Narco. Although the terms of sale are FOB
shipping point, which requires the consignee to
originate shipping damage claims, Dixie-Narco will
gladly help if you must file a claim.
UNPACKING THE VENDER
Remove the stretch wrap, fiberboard edge protectors
and corrugated front protector from the outside of
vender.
Do not store the vender with stretch
wrap on. Stretch wrap could bond to
the vender’s surface, which could
damage the finish.
Remove the shipping boards from the bottom of the
vender. The shipping boards are attached by the
leveling legs. To avoid unnecessary damage to the
leveling legs or base, remove the shipping boards by
using a 1-1/2 inch socket type wrench to unscrew the
leveling legs. Be sure to replace the legs after
removing the shipping boards.
Once the vender is unpacked, check the recovery unit
for any additional parts, price/ product labels,
service/operation manual or other information
concerning factory-equipped accessories such as coin
mech and validator.
WARNING: TO AVOID THE
POSSIBILITY OF A FIRE
HAZARD, DO NOT STORE
ANYTHING OR ALLOW DEBRIS
OF ANY KIND TO ACCUMULATE
IN THE BOTTOM OF THE
SERVICE AREA, IN AND
AROUND THE REFRIGERATION
COMPARTMENT OF THE
CABINET, OR IN FRONT OF
THE EVAPORATOR AND
CONDENSER COILS.
ELECTRICAL POWER NEEDED
Refer to the cabinet serial number plate to determine
the proper voltage and frequency the machine
requires (domestically, this requirement is 120 VAC,
60 Hz). The cabinet serial plate also indicates the
amperage of the vender. The vender must be
plugged into its own properly rated single phase,
alternating current outlet with its own circuit protection
(fuse/circuit breaker).
DO NOT USE AN EXTENSION CORD.
GROUND THE VENDER
The vender is equipped with a three-wire power
supply cord and MUST be plugged into a properly
grounded outlet.
DO NOT REMOVE THE GROUND
PIN OR IN ANY WAY BYPASS,
MODIFY, DEFEAT, OR DESTROY
THE GROUNDING SYSTEM OF
THE VENDER.
If the outlet will not accept the power cord plug,
contact an electrician to install a proper AC outlet.
FAILURE TO COMPLY WITH
THESE INSTRUCTIONS MAY
SUBJECT THE USER TO THE RISK
OF INJURY OR ELECTRICAL
SHOCK WHICH CAN BE SERIOUS
OR FATAL.
INSTALLATION AND SETUP
INSTRUCTIONS
Open the service door on the right side using the key
provided in the coin return cup, or if shipped with a
locking clip, remove the clip and install the lock.
Ensure there is no power to the AC Distribution Box.
On venders with a main power switch on the AC
Distribution Box the switch needs to be in the OFF
position. On venders with a main power quick
disconnect plug on the AC Distribution Box the quick
disconnect plug needs to be unplugged. Check that
all connectors are firmly seated on the control board
and at the various components on the service door
(coin mech, keypad, etc.).
Retrieve the main power plug from the hole in the rear
of the vender and plug the cord in a properly
grounded 120VAC, 15 Amp receptacle (U.S. and
Canada).
Open the service door and apply power to the AC
distribution Box (if equipped with a bill acceptor, the
acceptor should cycle twice). The display on the door
should scroll the message “USE EXACT CHANGE”,
the fluorescent lamp should be lit and the cooling unit
should start.
If the display scrolls “OUT OF SERVICE”, or the
cooling unit fails to start, refer to the
TROUBLESHOOTING FLOWCHARTS beginning on
page 29.
SERVICE NOTE
Battery Backup
The battery backup is used to retain information
programmed in the system (pricing, time, date, etc.).
in case of power interruptions, or any time the main
power is off. When the vender is shipped, the battery
is connected and memory is being maintained. If the
vender is to be stored for long periods of time,
disconnecting the battery is recommended. The
following steps will guide you through this procedure:

INSTALLATION AND SETUP

Open the service door and unplug the main power
harness located on the front of the power box.
1. Locate the main control board mounted on the
right side wall.
2. On controllers with a cover, remove the screw
securing the cover to the board.
3. The backup system jumper is located just
below the battery near the center of the board
(refer to figure 1, page 26).
4. Remove the jumper covering the pins and
place it on only one pin for storage.
5. Reinstall the cover, if used, and tighten the
screw.
6. Reverse this procedure to connect the battery.
PLACING THE VENDER ON
LOCATION
!! CAUTION !!
DO NOT TRANSPORT THE
VENDER TO OR FROM THE
LOCATION LOADED WITH
PRODUCT OR DAMAGE TO THE
VENDER MAY RESULT.
The vender is intended for INDOOR USE ONLY. It
should be kept out of direct sunlight and away form
any heat source.
The vender must be on a solid, flat and level surface.
Ensure the flooring can bear the weight load of a fully
loaded vender (approximately 1150 lbs.). The vender
must be positioned close enough to an electrical outlet
so that an extension cord is not required. If the
machine will be subject to user misuse or vandalism, it
is recommended that the vender be secured to the
floor or wall as described in Dixie-Narco Technical
Bulletin 344. Due to the large size and weight of the
Vender, never attempt to move the Vender with a
Hand Truck or Stair Climber. Use a pallet jack or
Vender/Cooler Dollies at all times when moving the
Vender. The vender should never be slid or pushed in
place. Never side load the leveling legs; doing so will
cause damage to the legs. Do not transport the
vender to or from customer locations loaded with
product, as damage may rtesult due to excessive
weight. Call the Dixie-Narco Technical Service
Department or your Dixie-Narco Representative for
assistance.
LEVEL THE VENDER
Adjust the front leveling legs, ensuring that an even
gap exists between the glass door and the top
security angle and receiver box, and then level the
cabinet front to rear. A carpenter’s level will help
verify that the vender is level. Leveling legs are
adjusted using a wrench or socket 1 ½” in size. If the
vender is to be used in a bank of equipment, check
the top and sides for proper alignment. If you are
unable to properly level the vender, select an alternate
location. NEVER PLACE OBJECTS UNDER THE
LEVELING LEGS OF THE VENDER
DANGER
THE VENDER MUST BE
PROPERLY LOCATED AND
LEVELED. IF THE MACHINE WILL
BE SUBJECT TO USER MISUSE
OR VANDALISM IT IS
RECOMMENDED THAT THE
VENDER BE SECURED TO THE
FLOOR OR WALL AS DESCRIBED
IN DIXIE-NARCO TECHNICAL
BULLETIN 344 TO MINIMIZE THE
RISK OF INJURY OR DEATH
FROM TIPPING. CALL THE DIXIE-
NARCO TECHNICAL SERVICE
DEPARTMENT OR YOUR DIXIE-
NARCO REPRESENTATIVE FOR
ASSISTANCE.
SPACE THE VENDER
Do not block the rear of the vender. Maintain a
minimum of 4 inches (10 cm) from the wall to ensure
adequate airflow to the condenser and compressor.
At the front of the vender, make sure that nothing
obstructs the air intake at the bottom of the service
door and cabinet. At the rear of the vender, make
sure nothing obstructs the air exhaust at the bottom of
the cabinet.
WARNING
TO AVOID THE POSSIBILITY OF A
FIRE HAZARD, DO NOT STORE
ANYTHING OR ALLOW DEBRIS OF
ANY KIND TO ACCUMULATE IN
THE BOTTOM OF THE DOOR, IN
THE BOTTOM OF THE SERVICE
AREA, IN AND AROUND THE
REFRIGERATION COMPARTMENT
OF THE CABINET, OR IN FRONT
OF THE EVAPORATOR AND
CONDENSER COILS.
INSTALLING PRICE LABELS
There are 2 sheets of pricing labels included in the
service manual package. They are double sided and
range in price from .25 to 9.95. The price labels are
inserted at the top of the front knuckle of each release
mechanism.
Remove the pricing label sheets from the service
manual package and gently remove the label
corresponding to the vend price of each selection by
tearing at the perforation. The label is inserted
between the grooves at the top of the front knuckle by

INSTALLATION AND SETUP
6
slightly bending sides of the label toward the front of
the vender being careful not to crease the label. Once
inserted, push the label firmly against the front of the
knuckle. This will insure the label is locked in place
and will not fall out during normal operation of the
vend mechanism.
INSTALLING FLAVOR CARDS
For problem free vending, it is necessary to load the
vender consistently with same product every time the
vender is filled. To ensure consistent loading, flavor
cards are included with every vender and should be
installed into the product pusher to designate to the
route driver which product the column is set for.
To install the flavor card, simply detach it from the
sheet at the perforation and slide it into the slots in the
product pusher .
COIN CHANGERS & OTHER
ACCESSORIES
The vender must have an MDB coin changer installed
and can have an MDB bill acceptor installed as well.
If the MDB coin changer and other MDB accessories
are not factory installed, refer to the instructions
received form the manufacturer of the MDB coin
changer and other MDB accessories for proper set-up
and installation.
The vender will support the following Domestic MDB
coin changers:

The above listed peripherals indicate units that have
been tested by Dixie-Narco at the time of printing of
this manual and are not all-inclusive. For information
regarding other types not listed here, please contact
Dixie-Narco Technical Service Department.
SETTING THE TEMPERATURE
CONTROL
This vender is equipped with a manual thermostat. It
is located on the power distribution box inside the
service area. This thermostat is factory pre-set to
maintain a cabinet temperature of 33 to 38 degrees
Fahrenheit (1 to 3 degrees centigrade), however,
occasional adjustment may become necessary. It is
also a good practice to ensure the proper operating
temperature prior to installing the vender on location.
To set the temperature, apply power to the vender
and allow it to run for several hours with the glass
door closed or until the minimum cabinet temperature
is achieved. Then, using one of the methods below,
verify the temperature inside the cabinet:
1. If your vender is equipped with an electronic
temperature sensor, use the keypad on the
service door to show cabinet temperature in
Fahrenheit by pressing the F key followed by
the asterisk (*) key or in Centigrade by
pressing the C key followed by the asterisk
key. The temperature will be shown on the
digital display located on the front of the
service door.
2. If your vender is not equipped with a
temperature sensor, place a thermometer in
the center of the C shelf when vender is first
powered up. Make sure the thermometer is
placed in a location that permits reading the
temperature with the glass door closed. This
will prevent the introduction of warm, ambient
air.
Adjustments are made by turning the screw in the
center of the control (Shown in fig. 1) clockwise for
colder product or counterclockwise for warmer
product. It is recommended that the control screw be
adjusted in very small increments allowing the
refrigeration unit to cycle off and then verifying the
temperature again using one of the methods listed
above prior to further adjustment.

LOADING THE VENDER
All venders are shipped with an assortment of
spacers. Please contact a Service Representative or
refer to the proper Technical Publication for spacer
settings.
Load product in each column one package at a time
insuring that the package being loaded is in front of
the product pusher. If the package is narrower than
the column, use the correct spacer to insure a snug
(not tight) fit against the left side of the column. Test
the column spacing by pulling firmly on the front
package. If the package pulls out of the column
easily, recheck the spacer being used. Also insure
that the package is stable within the column (doesn’t
move excessively from side to side). Some packages
are wider at the base than in the center. These
packages will have the tendency to lean forward on
the front of the gate assembly and create a jam if not
properly set up. A properly loaded column will allow
the product to slide freely into the gate area but not
allow the product to squeeze past the front knuckle of
the release mechanism. After loading the vender, test
vend each column to insure proper operation.
LOADING CHANGE TUBES
The changer tubes can be loaded using one of the
following methods:
1. Load the coin mechanism with coins to the
desired level by inserting coins in the loading
slots on the coin tube front.
Minimum coin tube levels are:
6-8 nickels
7-8 dimes
5-6 quarters
Note: A low coin level in the coin tubes will
interfere with operation of the bill validator.
2. For exact cash accountability and to insure
maximum dollar bill acceptance, load the
mechanism utilizing the coin insert slot on the
front of the vender while in the coin tube
fill/dispense mode in the test menu. (see
page 17 in the programming section for more
information)
(For additional information about coin mechanism,
refer to the manufacturer’s instructions.)
POWER DISTRIBUTION BOX
The power distribution box is where the 120VAC input
voltage is broken down to the main operating voltages
of the vender (24 VAC and 12 VAC) by a transformer.
Those voltages are sent to the controller via the JI (12
pin) connector. It also contains 3 fuses that protect
the VMC, transformer, and solenoids. The power
distribution box also distributes AC power to the lights,
evaporator fan, and refrigeration system, which are
always energized when the vender is powered up. It
is located inside the service area, mounted to the
back wall.
VENDING MACHINE CONTROLLER
(VMC)
The vending machine controller is the heart of the
Glass Front Vender and is located on the right side
wall inside the service area. It contains the program
chip (EPROM), which controls all aspects of the
vender with the exception of the refrigeration unit and
lighting. It also contains the power supply which
regulates the voltages required to operate the vend
solenoids as well as the changer, coin mechanism,
digital display and all logic functions in the vender.
Keypad
The keypad is located on the front of the service door.
It consists of a 6X3 matrix, membrane switch pad and
a rubberized actuator pad. The pad utilizes the letters
A thru F on the left side and numbers 1 thru 0 along
with the * symbol and Clr to the right. The keypad is
where all of the vender programming is accomplished
and where the customers make their selections.
DIGITAL DISPLAY
The digital display is located directly above the
keypad on the front of the service door. It is an 8 digit
14-segment alphanumeric display. It is used to
convey information to the consumer as well as to the
person programming the vender. The backside of the
digital display, inside the service door, contains the
service mode switch. It is a blue button that is
depressed a number of times in order to access
different programming menus.

INSTALLATION AND SETUP
8
REFRIGERATION SYSTEM
The refrigeration system is a single piece unit and is
hermetically sealed. In the DN55##/54##/2145
models it consists of a ½ horsepower compressor, two
roll up style condensing units with separate fans, the
condensation overflow pan and the evaporator. In the
DN35## models it consists of a ½ horsepower
compressor, with a single fin and tube style
condensing unit with one fan, the condensation
overflow pan and the evaporator. The evaporator is
located behind the panel on the right side of the
cooling compartment directly adjacent to the bottom
shelf. The remainder of the unit is located behind the
delivery bin, mounted to the bottom of the cabinet.
This unit is designed for easy removal and
replacement from the front of the vender as a
complete assembly. A mechanical thermostat
regulates the cabinet temperature. The bulb of the
thermostat is attached to the evaporator coils and
reads the temperature of the refrigerant inside the coil.
SHELF ASSEMBLY
Typically, there are 5 shelf assemblies in every
vender; however, this can vary depending upon the
configuration specified at the time of ordering. Each
shelf consists of either 6, 8, or 9 columns. Each shelf
is capable of holding a variety of products. The shelf
assembly consists of the tray, where all of the
following parts are mounted: Gate assembly, shelf
stabilizers and the slide/pusher assembly. These
items are discussed in detail below.
SHELF STABILIZERS
Some packages will have the tendency to become
unstable or bounce to the delivery bin when vended
due to the design of the bottom of the package. This
can lead to a product jam. The shelf stabilizer (the
clear Lexan tab at the front of the tray) is used to
prevent this from occurring by acting as an extension
of the shelf.
Unless otherwise specified at the time of ordering,
shelf stabilizers are installed on the C and D shelves
of the vender. The stabilizers that are installed on the
C shelf can also be used on the A and B shelves as
needed for product stability. The stabilizers installed
on the D shelf must be used only on that shelf as they
are longer and may interfere with the proper vending
of a column. Do not use shelf stabilizers on the
bottom tray as product jams may occur.
To install the stabilizers, the slide assembly must first
be removed from the column. The stabilizer is
inserted on the bottom of the slide assembly by firmly
pushing the square hole in the stabilizer onto the front
locking tabs of the slide. The slide is then installed
back into the column.
GATE ASSEMBLY
The gate assembly is mounted on the front portion of
the tray assembly and contains the vending
mechanism. Incorporated in the gate assembly are
the front and rear knuckle assemblies as well as the
product kicker.
In standby operation, the front knuckle is in the
blocking position, which holds the front (displayed
product) in position to be vended. The rear knuckle
assembly is in a flat position, which allows product to
enter the gate area, and the kicker is flush to the rear
knuckle assembly. A stainless steel pin is inserted
through the rear most portion of the front knuckle
assembly and connects to a solenoid plunger below
the tray. When a selection is made, the solenoid
energizes pulling the plunger toward the back of the
tray. At the same time the front knuckle is opened
into a flat position, the rear knuckle is closed to a
blocking position, holding the remaining product out of
the gate area, and the kicker is extended to firmly
push the front (displayed product) off of the tray. The
solenoid is energized for approximately 1-½ seconds
to allow ample time for the displayed product to be
ejected from the shelf. The solenoid is then released
and the front knuckle returns to the blocking position,
the rear knuckle and kicker return to their standby
position and the next product slides into the vend
(display) position.
SLIDE/PUSHER ASSEMBLY
The slide/pusher is located on the bottom of each
product column. Its purpose is to provide a slick,
friction resistant surface for the product to rest on.
The product pusher is mounted on the top of the slide
and incorporates a coil spring in the body that
attaches to the bottom of the slide through a slit. This
spring adds needed tension to insure that all products
in the column remain tight against each other and are
allowed to progress into the gate area.
Although these pushers reduce the effects of dirt and
grime, periodic cleaning and lubrication of the slides is
recommended. NEVER USE PETROLEUM BASED
CLEANERS OR LUBRICANTS ON THE
SLIDE/PUSHER ASSEMBLIES AS THEY MAY
BECOME BRITTLE OR DISCOLORED.

PROGRAMMING
9
GENERAL INFORMATION
In order to fully utilize the many features of your
vender it is important that you first understand the
options available and procedures for programming the
vending controller unit (control board).
All programming, testing, and service functions are
accomplished by using the keypad in an easy to
follow, display prompted format. There are four modes
of operation for servicing, testing, and setting up your
vender. The modes of operation are accessed by,
opening the service door, and pressing the service
button (blue button on back of display module or the
service button on the control board).
The service button will cycle through each of the four
modes in turn: Service Mode, Test Mode, Set-Up
Mode and Setup Mode 2. In each of these modes,
the “A” key is used to scroll through the available
options/settings within that mode/selection. (Note: In
each of the mode selections, pressing the character
key next to the listed option will take you directly to
that feature -see menu items chart on page 12.), the
“*” key is used as an enter key to select the currently
displayed item/feature, and the “CLR” key is used as a
done or exit key. Closing the service door or pushing
the service door switch will exit the function you are
currently in and place the vender back in service.
EXTERNAL DISPLAY ITEMS
(HOT KEYS)
Allows the service technician to view several items via
the display without opening the vender. There are four
options that can be viewed externally:
