SECTION 4: Vender Maintenance
Vender Maintenance
What to Clean
CAUTION: Electrical and electronic components should
NEVER be subjected to water.
Belts:
The belts should always be kept clean and free
of debris to ensure efficient operation, as well as to extend
the life of the belts.
Cells:
Make sure the cells are free of dirt, syrup, and
debris. Build-up of foreign material, especially syrup from
broken or leaking packages, can cause the cell to stick and
adversely affect the cell’s performance. Use warm soapy
water or other food grade cleaning agents to maintain a
clean smooth surface. Also make sure that the cells are
level and seated properly in the tracks that they slide into.
Condenser and Evaporator Coils:
For
efficient operation, the condenser and evaporator coils
must be kept clear of any dirt or foreign materials. Clean
dirt and debris from the condenser and evaporator coils
with a small light-bristled brush, vacuum cleaner, or
compressed air. This will help to ensure an extended unit
life.
VMC and DMC:
The vender’s control boards
(VMC and DMC) should always be enclosed by their
covers to protect them. Routine cleaning is not necessary
but, if desired, the boards’ area may be blown out with
compressed air.
Delivery Bin:
Make sure that the delivery bin
remains clean and free of any debris or other objects that
may block the optic sensors. Bottles sometimes have
a tendency to lose their labels, which may be left in the
delivery bin. If objects are left in the bin and the sensors
are blocked, the board will assume there is a package in
the bin and will not deliver product to the bin.
Elevator Arm and Cup Tracks:
The elevator
arm and cup assemblies travel in aluminum tracks that
guide these components. Make sure that these tracks are
kept clean and free from foreign material such as dirt,
syrup, or other debris. Use a wet cloth to wipe these tracks
clean. Avoid using any type of silicone or lubricant, as
they may tend to collect dirt and will adversely affect
performance.
Product Cup:
The cup floor should be kept clean
and free of syrup.
Lubrication
Latch Strike Nut:
The latch strike nut should be
lubricated as needed.
Refrigeration Unit:
The refrigeration unit is a
sealed system that does not require any lubrication. Also,
the condenser and evaporator fan motors do not require
any lubrication.
Preventive Maintenance
Vender Leveling:
Make sure that the vender is
level when placed on site. If the vender is not properly
leveled it can begin to accumulate standing water, which
over a period of time may begin to freeze and will
eventually freeze the evaporator. Another problem that
may occur from an unleveled vender will be improper
vending, which would include but not be limited to
product not vending from cell, product vending slowly
from cell, product not being delivered to the delivery bin,
or product jamming.
Vender Support Leg:
The RVV is equipped with
a vender support leg. This leg is similar to the leveling
legs but is longer and is located in the bottom door hinge.
It is very critical that after the vender is placed on location
and is leveled that this support leg is brought down even
with the ground, floor, or whatever surface the vender is
placed on. If the support leg is not making contact with
the ground surface there is a possibility of the vender
tipping over when the door is opened, possibly resulting in
broken bones, dismemberment, or even death
.
Lighting System:
The lighting system contains
extremely high voltage (upwards of 600 volts), and power
should always be disconnected when working with or
around this portion of the vender. Light bulbs should
be replaced whenever one or more of the bulb ends are
blackened or discolored, or when the lights are flickering
or are not lit, and it has been determined that the ballast is
good. Replace these bulbs as soon as it is determined they
are bad. If it is decided not to use the lighting system, the
ballast MUST be unplugged. DO NOT remove the bulbs
and leave the ballast plugged in. Doing so can cause the
ballast to generate a very high amount of electrical noise,
which can cause problems with or permanently damage
electronic components.
