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 vendor 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 vendor. It is
important to point out that Automated Merchandising
Systems has no control over the vendor once it leaves our
factory.
Maintaining the vendor 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 vendor 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 vendor.
2. Always disconnect power to the vendor before
servicing. Allow only fully trained service technicians
to service the vendor if service must be performed
with the power on.
3. Always keep electrical connections dry. Do not place
the vendor in or near standing water.
4. Never use a worn or damaged power cord.
2.2.2 Improper Grounding
Some electrical components have a green or
green/yellow ground wire attached to a grounding point in
the vendor. 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 vendor will 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 vendor.
2. Always reconnect ground wires after servicing.
2.2.3 Fan Contact
Vendors 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 vendor before
servicing.
2. Always keep protective covers in place.
3. Always wear hand and eye protection when servicing
the vendor.
4. Always keep hands, hair, loose clothing and tools away
from fan blades.
5. Never insert hands or tools into concealed areas.
6. 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 helixes 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 caution when freeing a jammed helix.
1. Always disconnect power to the vendor or control
board before servicing the vend motors.
2. Always check for proper fit when loading products in
helixes 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 vendor.
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 certified
equipment. Unauthorized service to the
