This
model is a six (6) select, can or bottle vending machine that operates on the
"first-in, first-out" vending principle for all selections.
The
six selections are priced individually from $0.05 to $99.95 in five cent
increments (U.S. Currency). When adapted to accept international or foreign
currency, the maximum vend price is 255 times the smallest denomination of
coin accepted.
It is
equipped with an electronic control system. All programming of the vend
functions, pricing and features is done on the controller. Changes can be
made without any additional accessories or remote parts.
Each
machine is identified by a model and a serial number given on the Serial
Number Plate attached to the inside or back of the vending machine. Record
these numbers for your records. All inquires and correspondence pertaining to
this vending machine should reference the model and serial numbers.

INSTALLATION
|
|
|
|
Consult
local, state and federal codes and regulations before installation of the
vending machine. To minimize
installation time and to avoid service problems due to improper installation,
follow the instructions outlined in this manual.
Position the
vending machine in its place of operation no further than six feet from the
power outlet or receptacle and check that the door will open fully without interference.
Leave at least four inches of space between the back of the machine and any
wall or obstruction for proper air circulation.
Level
the vending machine, making sure all levelers are touching the floor. The
vending machine must be level for proper operation. If it is properly
leveled, it should not "rock" or "teeter" on any of the levelers. When the
vending machine is level, the door can be opened to any position and not move
by itself. Try the door half closed, straight out and in a wide open position
before deciding that the machine is level.
Remove
all shipping brackets, tape and inner packing material from the vending
machine. Operating the vending machine without removing the tape and packing
material could result in damage to the vending machine.
|
|
|
Do not
block the ventilating screens in front or in the rear of the vending machine.
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.
|
|
|
|
Prior
to connecting the equipment, the integrity of the main electrical supply must
be checked for correct polarity, presence of ground (earth) and correct
voltage. It is recommended that these checks be repeated at 6-month intervals
with the routine safety electrical testing of the equipment itself.
To
correct negative voltage, amperage, polarity, or ground (earth) checks,
consult a licensed electrician.
A
noise suppresser has been installed in this machine to compensate for any
mains signal noise that could interfere with the normal operation of the
controller.
|
|
|
Do not use extension cords.
