2.0 SAFETY
2.1 COMMITMENT TO SAFETY
Automated Merchandising Systems Inc. is
committed to designing and producing a safe product. As
with all electrical or mechanical pieces of equipment,
potential hazards exist. It is the intent of Automated
Merchandising Systems, through this manual and service
technician training, to alert individuals who will be servicing
our equipment to these potential hazards, and to provide
basic safety guidelines.
To reduce the risk of serious injury or death,
please read and follow all warnings in this manual. It is
important that we point out that these warnings are not
comprehensive. Automated Merchandising Systems can
not possibly anticipate all of the ways that service may be
conducted, nor all of the possible safety hazards that may
result from service. Therefore at all times we urge you to
beware of hazards such as electrical shock, mechanical
entrapment, and tipping a merchandiser during movement.
Automated Merchandising Systems strongly
recommends a commitment to safety on the part of all
servicing personnel or organizations. Only personnel
properly trained in vendor servicing should attempt any
service to the internal components of the merchandiser. It
is important to point out that Automated Merchandising
Systems has no control over the merchandiser once it
leaves our factory.
Maintaining the merchandiser in a
safe condition is the sole responsibility of the owner.
If you have questions concerning safety or service,
or would like more information, please contact the
Automated Merchandising Systems Service Department at
304-725-6921 or e-mail info@amsvendors.com.
2.2 SAFETY PRECAUTIONS
Below are listed safety precautions and safe
practices to follow to avoid injury from selected hazards.
This list can not possibly cover all hazards, therefore please
remember to
THINK SAFETY FIRST .
2.2.1
High Voltage Contact
Each merchandiser is designed to operate on a
specific voltage, either single phase 115VAC 60Hz or 220-
240VAC 50-60Hz, depending on the country. The voltage
is specified on the serial plate (Refer to Section 1.2 Model
Identification). High voltage areas include the electrical
panel, the refrigeration unit and fans, and the fluorescent
lamp. It is important to understand that contact with the
high voltage wiring can result in injury or death.
1. Always test the outlet for proper voltage, polarity and
grounding before plugging in the merchandiser.
2. Always disconnect power to the merchandiser before
servicing. Allow only fully trained service technicians
to service the merchandiser if service must be
performed with the power on.
3. Always keep electrical connections dry. Do not place
the merchandiser in or near standing water.
4. Never use a worn or damaged power cord.
2.2.2 Grounding
Some electrical components have a green or
green/yellow ground wire attached to a grounding point in
the merchandiser. If it becomes necessary to remove a
ground wire during service, note how the wire is attached,
including the locations of any washers. After servicing,
make sure that the wires and washers are replaced exactly
as they were. Note that the merchandiser may appear to
work normally without the ground wires, but there will be a
potential shock hazard from ungrounded components.
1. Always test the outlet for proper grounding before
plugging in the merchandiser.
2. Always reconnect ground wires after servicing.
3. Test the ground fault circuit interrupter (GFCI)
periodically to insure proper operation.
2.2.3 Fan Contact
Some merchandisers are equipped with electric
fans, which can start automatically. These fans are
guarded to prevent accidental contact. However, removal
of guards or other components can leave fan blades
exposed and create a physical hazard.
1. Always disconnect power to the merchandiser before
servicing.
2. Always wear hand and eye protection when servicing
the merchandiser.
3. Always keep hands, hair, loose clothing and tools away
from fan blades.
4. Never insert hands or tools into concealed areas.
5. Always replace protective covers after service.
2.2.4 Helix Motion and Jamming
Energized vend motors can turn a helix with
considerable torque, creating a possible entrapment
hazard. Also, turning helices may eject tools or other
objects left on trays. A helix that is jammed or caught can
store energy as it binds, which can cause it to twist or
spring outward suddenly even if power is disconnected.
Use gloves and caution when freeing a jammed helix.
1. Always disconnect power to the merchandiser or
control board before servicing the vend motors.
2. Always check for proper fit when loading products in
helices to avoid jamming.
3. Always restrain the helix before freeing a jammed or
caught helix.
4. Always wear hand and eye protection when servicing
the merchandiser.
5. Always keep hands, hair, loose clothing and tools away
from moving parts.
2.2.5 Refrigerant Release
The refrigeration system is pressurized and sealed
at the factory. Puncturing or cutting any component in the
system will cause refrigerant gas and liquid to be propelled
out of the system, creating an immediate physical hazard.
Use caution to avoid accidentally opening the refrigerant
system.
It should also be noted that releasing refrigerant to
the atmosphere is a federal crime and is punishable by law.
Any service work requiring the system to be opened must
be performed by a licensed technician using
