INTRODUCTION
This manual contains instructions, service and installation guidelines for the
Stand Alone Multi-zone/Cold/Frozen Food Vendor. Please read this manual
thoroughly and follow the instructions. The initial set-up of a vendor is a very
important step of insuring that the equipment operates in a trouble-free manner.
This vendor can be factory configured to have two
temperature compartments (top and bottom)
in a single
vending machine separated by moveable air deflectors and
insulating barrier. The vending machine has an air duct that
runs up and down on the back inner wall of the cabinet. Each
compartment can have 3 moveable trays and a total of 6 trays
for the entire vending machine. The vending machine will
maintain 2°C (36°F) in the Top compartment and down to -
24°C (-12°F) in the bottom compartment at an ambient range
of 4.4°C-32°C (40°F-90°F). The temperature setting for both
compartments are set by the controller (program).
TOP
BOTTOM
The top compartment has a heater system to maintain constant temperature
across varying ambient temperatures. This consists of a heater, temperature
sensor, air circulating blower and relays
The bottom compartment has a temperature sensor and an insulated
refrigeration system. Cool air is drawn from the refrigeration system’s evaporator
coils through the air duct and is deflected into the bottom zone by a moveable air
deflector. There are openings in the bottom trays to allow air to circulate around
the products.
All programming of the pricing, vend functions and features are also done at the
controller. Changes can be made without any additional accessories or remote
parts. Selections can be priced individually from $00.00 to $655.35 in five cent
increments (US currency). Cash accountability records, total cash transactions,
total vend cycles performed by the vendor, information for individual selections,
complete rows or total machine can be compiled and used for inventory and
ordering records. Electrical malfunctions are recorded and displayed when the
vending machine is placed in the Service Mode. Non-functional motors or
selections are indicated. Each selection has an individual motor. Functional
selections will continue to operate if other motors become nonfunctional.
The vending sequence is "first-in, first-out" for each selection, permitting stock
rotation to maintain fresh products in the vending area.
Each variant has the capability of supporting a "satellite" vending machine, such
as a direct wire CB300-SAT, or a USD satellite food such as a MZF Model 3530.
The satellite vendor utilizes the vendors existing controller, coin mechanism, bill
validator and keypad to perform the vend functions they require. The model 3530
has on-board refrigeration and motor controls. For details on the satellite vendor,
refer to the Service Manual pertaining to the specific vendor for installation
instructions.

UNPACKING
This vending machine was thoroughly inspected before leaving the factory and
the delivering carrier has accepted this vendor as their responsibility. Note any
damage or irregularities at the time of delivery and report them to the carrier.
Request a written inspection report from the claims inspector to file any claim for
damage. File the claim with the carrier (not the manufacturer) within 15 days
after receipt of the vending machine.
Carefully remove the outside packing material so as not to damage the finish or
exterior of the vending machine. Inspect the vending machine for concealed
shipping damage. Report any damage hidden by the shipping material directly to
the delivering carrier on a hidden damage report.
Record the model number and serial number of the vendor for your records.
These numbers can be found on the Serial Plate on the rear of the cabinet
and/or inside the vendor. Refer to these numbers on all correspondence and
inquiries pertaining to this vendor.

INSTALLATION
•This vendor should only be installed where it can be overseen by trained personnel.
•The maximum safe tilt angle of this vendor is 10°.
•Do not attempt to move the vendor by hand; it should only be moved using equipment
with the proper load rating.
•Consult local, state and federal codes and regulations before installing the vendor.
•Retrieve the keys to the vendor from the coin return cup.
•Open outer door and remove all internal packing material.
Position and level vendor prior to connecting vendor to power. All set up
must be completed prior to prevent harm to the installer or vendor.
POWER CORD INSTALLATION
The power cord is a 14 gauge cord and is fastened to
rear mounting box so it stays with the machine and
doesn’t get changed with a lighter gauge cord. The
power cord is connected and routed under the cover
as shown in Figure 2. Keep power cord secured on
the center back of the cabinet until the vendor is
placed into its final location to prevent damage to the
cord.
Position the vendor in its place of operation no
further than nine feet from the power outlet or
receptacle. Check that the door will open fully
without interference. Leave at least four (6”) inches
of space between the back of the vending machine
and any wall or obstruction for proper air
circulation.
Figure 2. Power Cord
LEVEL THE VENDOR
All levelers must touch the floor. The vendor must be level for proper operation,
cabinet to door alignment, condensate drainage, and for acceptance of coins
through the coin mechanism.
GROUNDING (EARTHING) & ELECTRICAL
Before connecting the vendor, the integrity of the main electrical supply must be checked
for correct polarity, presence of ground (earth) and correct voltage. Please refer to the
Safety Manual and Installation Guidelines Manual (P/N 4206816) that shipped in the
service package with your vending machine. These checks should be repeated at six (6)
month intervals with the routine safety electrical testing of the vendor itself.
If the receptacle is not properly grounded or polarized, you should contact a licensed
electrician to correctly polarize and/or ground the receptacle to ensure safe operation.
For proper operation of any equipment utilizing electronically controlled
components, the equipment should be placed on an isolated or dedicated noise-
free circuit, properly polarized and grounded.

TRAY ADJUSTMENTS
By re-timing the augers, difficult-to-vend items can be dispensed more dependably. By
altering tray spacing, larger items can be vended. By changing the tray configuration,
different product mixes can be accommodated.
VERTICAL SPACING
The trays can be adjusted up or down in half-inch increments to provide additional
headroom for vending taller products. When increasing the height in one area, the same
amount of room will be lost at the tray above or below the one being adjusted.

SPIRAL ADJUSTMENT
SNACK/CANDY/FOOD TRAY
Each auger can be rotated in 20° (degree) increments for a different product vend drop-off
point. Most items can be vended successfully when the auger end is positioned at 6
o'clock.
The general rule is - the narrower the
product, then the higher the timing.
•Thick Products - 4-6 o’clock
•Most products – 6 o’clock
•Thin Products - 6-8 o’clock
TO CHANGE AUGER TIMING
1. Remove the motor cover. See Figure 5f.
2. Raise the motor slightly and pull forward on
the auger until it separates from the motor.
3. Rotate the auger to the desired position and

Loading Coin Mechanism
The Coin Mechanism must be loaded with
some level of each coin in order for the vendor
to operate properly. The coins need to be
loaded into the coin mechanism by insertion
into the front coin insert. First enter the
SERVICE MODE then TUBE FILL MODE
(See SERVICE MODE instructions –
COIN/TUBE FILL MODE
Each tube should be kept loaded with at least
one roll of each coin to keep above the tube
low level sensors. Once the tubes are loaded
to these levels the Dollar Bill Validator will accept bills. If the coin
tubes fall below this level the Dollar Bill Validator may stop
accepting bills and the front display will indicate "EXACT CHANGE
ONLY".
Alternatively, you can load the coins into the slots above the
respective coin tubes, making sure to load the correct coins into
their correct tubes. This is not the preferred method. By using
TUBE FILL mode the control board can then accurately
determine coin levels.
On some Coin Mechanisms there are buttons above each
tube to dispense the coins (may vary depending on which coin
mechanism that is used). The coins can also be dispensed
within the Service Mode described later.

AUTOMATIC DELIVERY LIFT
This information is for machines with the GVC2 Control Board (part number 4214682.004)
and software version V3.3.10177 and higher.
INTRODUCTION
The Automatic Delivery Lift system is designed to lift vended products to the 2012
American Disabilities Act (ADA) height requirement level from the locations floor. This
same system can also provide an enhanced customer experience for those locations
where an almost hands free vended product presentation is desirable.
The Delivery Lift system is an option that can be used on the line of Delivery Lift Ready
Machines (also called ADA ready machines) and consists of an LED illuminated product
delivery box with a motorized product lift plate, a set of product height sensors, a motorized
delivery box door (Auto Door) and a Blue LED illuminated activation button.
The delivery lift system can be factory installed or provided as a retrofit kit for field ADA
ready machines. See the list of ADA ready model numbers or contact a sales or service
representative for more information.
INITIAL SETUP – SERVICE MODE
When an Automatic Delivery Lift system is installed in an ADA ready machine, it is
automatically detected when a controller Service Mode Motor Count is done. The Motor
Count will show the tray motor count briefly with the 3 additional delivery lift motors before
returning to a tray motor count only. Once a Delivery Lift system is detected, it will complete
a functional test at every Motor Count or at machine power on. When the Delivery Lift is
moving, the Blue Delivery Lift Button on the front of the machine will flash and can be
pressed to stop the Delivery Lift operation if necessary. Information on Service Mode
Configuration menu and Diagnostic Mode menu options are listed on the following pages.
SALES MODE
When a product is selected and vended, the product drops into the Delivery Lift Box after it
first passes by the iVend sensor to confirm that a product has been vended. Next, when the
machine is using the default BUTTON configuration mode, the Blue Delivery Lift Button will
be constantly illuminated for 10 seconds, during this period the Delivery Lift can be
activated. When the illuminated button is pressed, the Delivery Door will open, the Delivery
Lift will begin raising the vended product and the button will flash. The product will be
raised until a portion of the product package blocks the Delivery Lift sensors, indicating that
the product has reached the ADA delivery height. The machine display will now show
“Please Remove Your Product” and an audible beep will occur every 10 seconds until the
product is removed or one minute has elapsed. After one minute, the Delivery Door will
close and the “Please Remove Your Product” message will continue to be displayed. Once
the product is removed and the Delivery Lift Sensors are no longer blocked, the Delivery
Lift will return to the bottom of the Delivery Box and machine display will return to the sales
mode message and is ready for the next vend.
NOTE: If a customer grabs the product while the Delivery Lift is in operation, the Delivery
Lift Sensors may detect a sensor blockage and will stop the Delivery Lift at its current
location. Pressing the flashing Blue Delivery Lift Button will also stop the Delivery Lift.
SERVICE MODE PROGRAMMING & TEST FUNCTIONS
Once in the service mode the control functions can be accessed and used, these are the
service menus specific to the Automatic Delivery Lift functions.

CONTROLLER FUNCTIONS
IVEND® CYCLE
All vendor selections have been assigned at the factory to be monitored for iVend™
optical sensing.
For 5 milliseconds at the start of a vend, the iVend® optical sensor will be checked
to make sure it is not blocked, damaged or disconnected.
If blocked, damaged or disconnected - the normal home-switch-vend cycle will
be used and the optical sensors will be ignored. Both the vend motor and a vend
timeout timer are started.
•The selection motor rotates to the home-switch position.
•If there is a home-switch signal, then the vend is considered successful.
•I after 10 seconds there is no home-switch signal, the vend failed. The vend
motor is shut down and and MAKE ALTERNATE SELECTION is displayed.
The customer can press selection buttons to activate another motor or press the
coin return button.
If not blocked, damaged or disconnected - the iVend® Sensor System is used.
The vend motor and a vend timeout timer are started.
•The selection motor rotates to the home-switch position.
•If a product is detected during this time period, then the vend is considered
successful.
•If after reaching the home-switch position and a product is not detected, then the
vend motor will pause for 1 second while the controller continues to monitor the
optical sensor for product delivery.
oIf a product is detected during this pause, then the vend is considered
successful.
oIf a product is not detected, then the controller initiates a second vend cycle
and another vend timeout timer while continuing to monitor the optical
sensor.
If a product is detected during this second cycle, the motor will be stopped
immediately. The vend is considered successful. The 2ND VEND
accounting counter is increased by one.
If after reaching the home-switch position and a product is not detected,
then the vend motor is stopped and for 2 seconds the controller continues
to monitor the optical sensor for product delivery. If a product is detected,
the vend is considered successful. The 2ND VEND accounting counter is
increased by one.
Otherwise, if no product is detected, the selection is sold out. Such a state
will trigger the display of the
MAKE ALTERNATE SELECTION message.
The amount of credit is displayed. The customer can press selection
buttons to activate this or another motor or press the coin return button.
oIf after 10 seconds there is no home-switch signal and no product is
detected, then the vend failed. The vend motor is shut down and
MAKE ALTERNATE SELECTION is displayed. The customer can press
selection buttons to activate another motor or press the coin return button.
NOTE: Force Vend is disabled to permit customer to retrieve deposited
money.

4.9 HEALTH SAFETY (HS)
THE HEALTH SAFETY FEATURE CAN NOW BE CONFIGURED FOR 2 TEMPERATURE
ZONES. A LOWER ZONE AND AN UPPER ZONE AS DETAILED IN THE HEALTH
SAFETY MENUS BELOW.
The HEALTH SAFETY feature prevents the sale of perishable food if the air temperature
inside the Food Vendor compartment rises above the Health Safety temperature limit for
more than 15 minutes. The perishable products being vended must match the refrigeration
configuration.
HEALTH SAFETY MENUS - This menu allows the user to specify the operating zone to
meet health safety requirements for cold and frozen food. The health safety requirements
can also be applied to an individual Item(s), Row(s), or ALL (whole machine). If the health
safety requirements are violated then the Item(s), Row(s) or the whole machine is shut down
accordingly.
HEALTH SAFETY ZONES - Health Safety settings are split into two zones, Upper Zone and
Lower Zone. Only the Lower Zone setting will be used when the machine is configured
as a Cold, Cold Food, Single Zone (SZ), Dual Zone (DZ),Single Zone Frozen (SZF) or
Single Zone Cold Food (SCF). The Upper Zone setting is used is for the Multi-Zone Frozen
(MZF) temperature mode. On a machine using the MZF setting, the Upper Zone follows the
HS rules for Cold Food and the Lower Zone follows the HS rules for Frozen Food.
IMPORTANT! The operator is responsible for ensuring the health safety of
vended products and to verify the machine HS settings. Make sure to Enable
All Items and Enable HS Zone Lower and/or Upper Zone before making any
other changes.
Warning: These settings require specific refrigeration systems and options in a
machine. Please review this document and consult the machine service manual
and if necessary, Vendnet Service at 1-800-833-4411 before making any changes
to the machine settings. Please have machine model number and serial number
information when calling Vendnet Service,
