A COMMITMENT TO SAFETY
The Vendo Company is committed to safety in every aspect of our product design. Vendo
is committed to alerting every user to the possible dangers involved in improper handling
or maintenance of our equipment. The servicing of any electrical or mechanical device
involves potential hazards, both to those servicing the equipment and to users of the
equipment. These hazards can arise because of improper maintenance techniques.
The purpose of this manual is to alert everyone servicing Vendo equipment of potentially
hazardous areas, and to provide basic safety guidelines for proper maintenance.
This manual contains various warnings that should be carefully read to minimize the risk
of personal injury to service personnel. This manual also contains service information
to insure that proper methods are followed to avoid damaging the vendor or making it
unsafe. It is also important to understand these warnings are not exhaustive. Vendo
could not possibly know, evaluate, or advise of all of the conceivable ways in which service
might be done. Nor can Vendo predict all of the possible hazardous results. The safety
precautions outlined in this manual provide the basis for an effective safety program.
Use these precautions, along with the service manual, when installing or servicing the
vendor.
We strongly recommend a similar commitment to safety by every servicing organization.
Only properly-trained personnel should have access to the interior of the machine.
This will minimize the potential hazards that are inherent in electrical and mechanical
devices. Vendo has no control over the machine once it leaves the premises. It is the
owner or lessor’s responsibility to maintain the vendor in a safe condition. See Section
I of this manual for proper installation procedures and refer to the appropriate service
manual for recommended maintenance procedures. If you have any questions, please
contact the Technical Services Department of the Vendo ofce nearest you.
SAFETY RULES
• Read the Safety Manual before installation or service.
• Test for proper grounding before installing to reduce the risk of electrical shock and
re.
• Disconnect power cord from wall outlet or air dam before servicing or clearing product
jams. The vending mechanism can trap and pinch hands.
• Use only fully-trained service technicians for Power-On servicing.
• Remove any product prior to moving a vendor.
• Use adequate equipment when moving a vendor.
• Always wear eye protection, and protect your hands, face, and body when working
near the refrigeration system.
• Use only authorized replacement parts.
• Be aware of inherent dangers in rocking or tipping a vending machine.

S-2 07/2003

SECTION I: VENDOR INSTALLATION
A. Vendors are large, bulky machines of signicant size and weight. Improper
handling can result in injury. When moving a vendor, carefully plan the route to be
taken and the people and equipment required to accomplish the task safely.
B. Remove all tape, shipping sealant, and Styrofoam from the vendor. Loosen
any shipping devices used to secure interior parts during shipping. Remove the
wooden shipping base attached to the vendor base by the vendor leveling screws.
Make certain the leveling screws are in place and functional.
C. Position the vendor three to four inches (7.6 cm to 10.2 cm) from a well-constructed
wall (of a building or otherwise) on a at, smooth surface.
IMPORTANT: The vendor requires three inches (7.6 cm) of air space from the wall
to ensure proper air circulation to cool the refrigeration unit.
D. Adjust the leveling screws to compensate for any irregularities on the oor surface.
Ideally, no adjustment will be necessary and the leveling legs will be ush with the
bottom of the vendor. A spirit level is a useful aid to level the vendor. When the
outer door is open, it will remain stationary if the vendor is properly leveled. Vendors
must be level to ensure proper operation and to maintain stability characteristics.
Do not add legs to the vendor. The leveling legs shall not raise the vendor
more than 1 1/8 inch above the ground.
E. Check the manufacturer’s nameplate on the left or right side of the vendor’s cabinet
to verify the main power supply requirements of the vendor. Be sure the main
power supply matches the requirements of the vendor. To ensure safe operation,
plug the vendor only into a properly grounded outlet.
DO NOT USE EXTENSION CORDS.
F. Recommended voltage specs = volts required + amps of circuit.
NOTE: Any power supply variance more than + 10% may cause the vendor to
malfunction.
* Power outlets must be properly grounded.
* Power outlets must be properly polarized, where applicable.
Test the outlets using the following information.
(Refer to Figure 1 on Page S-4.)

SECTION I: VENDOR INSTALLATION (CONTINUED)
For Type 1 and Type 2 outlets, test for Grounding and Polarization as follows:
1. With a test device (volt meter or test light), connect one probe to the receptacle’s
neutral contact and the other to the live contact. The test device should show a
reaction.
2. Connect one probe to the receptacle’s earth contact and the other to the live
contact. The test device should show a reaction.
For Type 3 through Type 5 outlets, test for Grounding as follows:
1. With a test device (volt meter or test light), determine which of the receptacle’s
power contacts is the live contact.
A. Connect one probe to the receptacle’s earth contact.
B. Connect the second probe to the left (or upper) power contact. If a
reaction occurs, this is the live power contact. If a reaction does not occur,
move the second probe to the right (or lower) contact. A reaction should
occur, indicating that this is the live power contact.
2. Connect one probe to the receptacle’s live power contact (as determined in step
1). Connect the second probe to the other power contact (neutral). The test
device should show a reaction.
IF THE ABOVE CONDITIONS ARE NOT MET FOR THE GIVEN OUTLET
TYPE, CONTACT A LICENSED ELECTRICIAN AND HAVE THE
NECESSARY CORRECTIONS MADE.

GENERAL
Vendo vending machines are provided with the appropriate power supply setting for your
area. Some models are equipped with step-down transformers, as required. This enables
the vending machine to operate on different main voltages. Refer to Section I. E. for
information to determine the main power requirements. Refer to the appropriate service
manual for details of step-down transformer operations.
The power sources just mentioned are standard for both household and commercial
lighting and appliances. However, careless or improper handling of electrical circuits
can result in injury or death. Anyone installing, repairing, loading, opening, or otherwise
servicing a vending machine should be alerted to this point. Apply all of the normal
precautions observed in handling electrical circuits, such as:
• Refrigeration servicing to be performed by qualied personnel only.
• Unplug the vendor or move power switch to off position before servicing or clearing
product jams.
• Replace electrical cords if there is any evidence of fraying or other damage.
• Keep all protective covers and ground wires in place.
• Plug equipment into outlets that are properly grounded and polarized (where
applicable), and protected with fuses or circuit breakers.
• All electrical connections must be dry and free of moisture before applying power.
A. Grounding Systems
Vendo vending machines are provided with the appropriate service cord for the
power supply in your area. The service cord will connect to the matching electrical
outlet. Always ensure that the outlet to be used is properly grounded before
plugging in the vendor. (See pages S-3 through S-5.)
The electrical grounding system also includes the bonding of all metal components
within the vendor. This involves a system of bonding wires identied by green or green
and yellow marking. The system uses serrated head screws, lock washers, and star
washers to ensure the electrical connection between parts. Maintenance of vending
equipment may involve disassembly. Include the above items when reassembling, even
if the vending machine may appear to function normally without them. Omitting any of
these items can compromise a link in the grounding system. See the appropriate service
manual or kit instructions for components and assembly instructions.
ALWAYS TEST TO VERIFY PROPER GROUNDING PRIOR TO
INSTALLATION TO REDUCE THE RISK OF ELECTRICAL
SHOCK AND FIRE
WARNING
SECTION II: ELECTRICAL HAZARDS (CONTINUED)

S-8 07/2003
S-9 07/2003
B. Servicing with “Power Off”
For maximum safety, unplug the service cord from the wall outlet before opening
the vendor door. This will remove power from the equipment and avoid electrical
and mechanical hazards. Service personnel should remain aware of possible
hazards from hot components even though electrical power is off. See the
appropriate sections of this manual for further information.
C. Servicing with “Power On”
Some service situations may require access with the power on. Power on servicing
should be performed only by fully-qualied service technicians. Particular
caution is required in servicing assemblies that combine electrical power and
mechanical movement. Sudden movement (to escape mechanical action) can
result in contact with live circuits and vice versa. It is therefore doubly important
to maintain maximum clearances from both moving parts and live circuits when
servicing.
Power to lighting and refrigeration system is shut off automatically by the electronic
controller when the outer door is opened.
NOTE: For power-on servicing of the vendor’s lighting system, turn lighting power on by
accessing the Lights test function of the electronic controller (see programming
on inner door).
For power-on servicing of the vendor’s refrigeration system, turn refrigeration
power on by accessing the Compressor test function of the electronic controller
(see programming on inner door).
SECTION II: ELECTRICAL HAZARDS (CONTINUED)
“POWER ON” SERVICING SHOULD BE ACCOMPLISHED ONLY BY
FULLY-TRAINED PERSONNEL. SUCH SERVICE BY UNQUALIFIED
INDIVIDUALS CAN BE DANGEROUS.
