INITIAL INSTALLATION (Model # 3578 & 3578G)
Read and follow all instructions outlined in the vendor Service Manual. Listed
below are the basic rules or steps that should be followed at the initial installation
of any vending equipment.
1. Carefully plan the route to be taken to the vendor operation site, making sure
that you have adequate manpower and proper equipment to safely handle the
product. Vending machines are relatively large and bulky and may be very
heavy. Improper handling can result in injury.
2. Remove all exterior packing material from the vendor in a manner that does
not damage the finish.
3. Remove the wooden shipping pallet or base. Make sure the leveling screws
for the vendor are in place and functional.
4. FOR Model #3578:
Position the vendor in its place of operation on a flat, smooth surface in such a
way that the vendor’s power cord easily reaches the power outlet or receptacle
(DO NOT USE AN EXTENSION CORD) and check that the door will open fully
without interference.
FOR Model #3578G:
Position the vendor on a Pedestal or Concrete Base or of similar nature so
that the entire Vending machine is located a minimum of 18 inches (450 mm)
above the grade level.
a. Use leg bolt down kit (order separately) to secure the machine to this
18” structure
(or)
WARNING:
This vendor is equipped with a 3 amp circuit breaker to protect the vend
circuit only. The refrigeration system is not on this breaker.
3578G has additional 8 amp circuit braker to protect Vendor

3578 •CB500 VENDOR |5
b. If it’s 18” metal structure and has 4 holes (same CTC as in machine
leg levelers) then remove 4 x leg levelers from the machine and use
4 x ½”-13 bolts (from local hardware) from bottom of the structure to
secure the machine to this 18” structure.
Also, secure this 18” structure to the ground.
The machine should be permanently connected to the electrical source.
Connect the electrical source to the terminal block located at the back of the
machine, just behind the air circulating panel. This should be done by a
licensed electrician.
5. Leave at least 4 inches (10 cm) of space between the back of the vendor and
any wall or obstruction for proper circulation.
6. Level the vendor to compensate for any irregularities of the floor, making sure
all levelers are touching the floor. If it is properly leveled, it should not “rock” or
“teeter” on any of the levelers. When the vendor is level, the door can be
opened to any position and not move by itself. Try the door half-closed,
straight out, and wide-open before deciding the vendor is level.
7. Remove all tape and shipping material used to secure interior parts during
transit.
GROUNDING (EARTHING) & ELECTRICAL
Prior to connecting the equipment, the integrity of the main electrical supply must
be checked for correct polarity, voltage, (earth) ground, and (amperage) circuit
protection. The fuse or breaker protecting the circuit must be rated at 15 amps or
greater.
It is recommended that these checks be repeated at month intervals with the
routine safety electrical testing of the equipment itself. To correct negative voltage,
amperage, polarity, or ground (earth) checks, consult a qualified electrician.
CAUTION:
Do not block the ventilating screens in front or in the rear of the vendor.
Always allow free ventilation behind a bank installation, so that exhaust
air is not trapped. Failure to do so could result in a refrigeration failure.
CAUTION:

10 | 3578 • CB500 VENDOR
DROP SENSOR
A drop (vibration) sensor on the delivery chute detects if a product has been
vended after a selection is made. The control board located on the back of the
main door controls the drop sensor sensitivity.
NOTE:
Please refer to DROP SENSOR instructions in the Programming Manual to restore
the drop sensor sensitivity to factory settings.
NORMAL VEND OPERATION
STAND-BY CONDITION
When the control board is in sales mode the display will show "ICE Cold" or the
amount of credit. If a customer presses a selection before establishing a credit, the
vend price for that selection will display, signaling the customer that more money is
needed for that selection.
ESTABLISHING CREDIT
Feeding coins into the coin mechanism or bills into the bill validator results in the
display of the corresponding credit value. The coin mechanism or bill validator will
accept money until the highest vend price has been reached or exceeded. At this
point a credit has been set up through the control board that will enable a vend for
any selection less than or equal to the established credit.
VALID SELECTION
Making a selection causes the selection switch to close. A logic level signal is
constantly sent out from the control board that then travels to each switch's
common position. When the switch is closed, the signal travels out the normally
closed position to the harness connection to the control board.
VEND SEQUENCE
The control board then distributes 24 volts DC through the door and cabinet wiring
harnesses and to the coil of the selected product cradle motor. At the same time,
the display will scroll. This indicates to the customer that a vend is in progress. As
the product cradle motor receives power, it will turn the product cradle, attempting
to vend a can or bottle.
PRODUCT DELIVERY
As the can or bottle drops onto the product delivery chute, the impact or vibration
allows the drop sensor to send a low voltage signal to the control board indicating
that a product has been vended. After receiving the drop sensor signal, the control
board will recognize how the vendor is programmed and responds accordingly.
The drop sensor sensitivity is factory calibrated and should need
adjustment.

3578 •CB500 VENDOR |11
Refer to Can/Bottle Menu section in the Programming Manual for additional
features.
REFRIGERATION
REFRIGERATION CONTROLS
The target temperature setting for the
refrigeration system has been preset at
the factory. Refer Programming
Manual.
If setting up for the first time, please
allow sufficient time for the refrigeration
system to cool the products.
REFRIGERATION
TROUBLESHOOTING
Know and understand how to service the unit and how it operates. Units may vary,
but the operation is basically the same. Never guess at the problem; find the
symptom before attempting any repair.
Unauthorized work done to the sealed hermetic system will void the warranty. The
sealed hermetic system is not to be worked on outside the Factory Service Center.
The three things that can go wrong with a sealed system and should be repaired at
the Factory Service Center are:
1. Low Charge - usually caused by leaks; look for oil around seals and welds.
Unit will not cool properly. The capillary tube will be frosted before it enters the
evaporator inlet tube.
2. Restriction in Systems (unit frost, then melts)- not cooling properly.
3. Bad valves - unit does not cool properly, noisy compressor.
CAUTION:
Do not place any object in the evaporator assembly area or inside
the cabinet area that will block the airflow. This may damage the
refrigeration system, which may voidthe refrigeration warranty.
WARNING:
Colder setting
does not cool
drinks faster and
may causedrinks
to freeze.
