jOPTIONAL) GUM AND MINT TRAY LOADING
SLIDE OUT DRAWER STYLE
The four select gum and mint dispenser is available in kit form or can be factory installed in a new machine.
Each selection will hold up to 20 packs of gum (5 stick per pack) or roll candy up to 5 inches in length. There
is a small metal tab that can be installed to allow you to dispense small rolls of anti-acid tablets or similar size
products.
All machines are prewired from the factory so you can install the gum and mint kit at a later date. The harness
for the gum and mint assembly is plugged into the motordistribution board (same board the trays are plugged
into).
LOADING INSTRUCTIONS
~Release the tray by pushing on the tab located on the right side of the tray and pulling the tray out to the stop.
To load, push the cover toward the rear of the machine. The two wide product selections are fitted with width
adapters, installed for dispensing longer products up to 5 inches in length. Place the packs of gum or rolls
of mints on their side and stack towards the back of the gum and mint tray. Upon filling each selection, slide
the tray cover forward back into place. Then slide the tray back into the machine until latched into position.
CAROUSEL LOADING
Open the refrigerated door section. To step the carousel there is a three (3) position service switch in the upper
right hand corner of the cabinet. If you press this button the carousel will step 30 degrees, l/l 2 of turn, which
is one small compartment. If you pull the stepping switch out the carousel will run continuously. Load the tray
compartments with the desired products. Then close the refrigerated door and rotate the carousel making
sure all items are in their correct compartment according to the pricing of that tray. When you first set up the
machine it will be necessary to reset the health control by going into the service mode and then come back
out. After the health control has been reset it will not be necessary to reset it. The health control will
automatically reset). The machine will then display the message “ENJOY ONE OF OUR FINE SNACK
PRODUCTS”. In 30 minutes the cold food timer will clock out and the health control will ensure that the
temperature inside the refrigerated area is below 45 degrees. Should the temperature be above 45 degrees,
only the cold food side will be shut down and NOT the vend selections. If a cold food selection is chosen,
the display will say “Make Alternate Selection”.

COLD FOOD SIDE SETUP
The Cold Food Side of the Combo unit comes equipped with nine (9) revolving shelves. The shelves are
designed in two halves, two 160 degree segments. Each segment can be quickly removed to change the
number of compartments per shelf and or to clean.
REMOVING TRAY HALVES
The tray halves can be easily removed to change the divider configuration for loading or for cleaning. They
are removed by the following procedures:
Underneath the center of the tray half is a leaf spring that is holding a stud attached to the tray. Pull down
on the spring to release the stud and pull the tray outward towards you.
2.The rear of the tray is inserted into a groove in the collar that is attached to the tray column. A slight
outward pressure may be required to disengage the rear of the tray from the groove.
3.
~The lip on each tray is designed with tabs that extend beyond the back edge of the tray. These tabs
slip underneath the adjoihing tray half to lock the two halves together and provide support for each other.
4.
When the tray half is removed you will notice that the 12 and 6 compartment trays have a security top
with clips that slip through the top and over the dividers. After changing the dividers or cleaning the tray
replace the security covers and clips. These are required to keep the dividers from being bent sideways
and allowing the food from being removed from the next compartment.
CAUTION: ALWAYS INSTALL THE SECURITY COVER AND CLIPS
-9-

REMOVING A CAROUSEL JAM
NOTE: If the carousel drive motor ever fails and the carousel is not in a position that the tray halves can be
removed, do the following to remove the chain.
1. In the bottom of the machine is a wing nut wrench. (A long piece of metal pipe with notches
at one end located on the left side in the bottom.)
2. The wrench is used to reach the wing nut on the drive motor bracket which is located on the back
wall. (Insert the wrench under the top sprocket.)
3. Loosen the wing nut only enough to drop the chain off the sprocket so the carousel can be turned
by hand in the reverse direction to unjam the unit. Do not loosen the wingnut enough that it
drops off. Once you have unjammed the carousel reinstall the chain, ensuring that the tray
dividers line up with the right security panel by each delivery door on the machine.
NOTE: Care must be taken to not over tighten the sprocket chain or the unit may bind up.
CHANGING DIVIDER POSITION CAROUSEL TRAY
Divider positions can only be changed while the tray half is removed from the machine.
1. Loosen the screw holding the clip in place. Then remcve the security cover and clip. See
Figure 3.
2. Lift the rear of the divider first with a slight upward pressure. This allows the divider latch
to slip out of the tray bottom. To replace the divider reverse this sequence of steps.
3. Replace the security cover and clips as required. Slip clip under screw and tighten.
See figure 3 below.

~HEALTH SAFETY SWITCH OPERATION
Operation and Testing
The international control board incorporates a Health Safety sensing system. If the temperature inside the
cold food compartment reaches 45 degrees or higher, during normal operations or there is a loss in power,
the control board will not allow any cold food to be vended (all of the H selections). If this condition exists “Make
Another Selectron” message will be displayed when the customer tries to vend a cold food selection.
The control board also incorporates a timer which allows the cold food box 30 minutes to cool down below
45 degrees before the Health/Safety system becomes active. At the initial start-up of the machine or after an
over temperature condition has occurred the Health/Safety switch timer must be set manually. But for normal
food loading and servicing the Health/Safety switch timer is automatically reset when the main door is closed.
To manually reset the Health/Safety switch for the 30 minute timer:
1, First open the main door.
2. ~Press the Mode button to go into the service mode, then press the mode button again.
3. The health control is now reset and the timer will start running when the front door of the machine is closed.
If power is lost or the temperature inside of the cold food area is above 45 degrees the health control will
have to be manually reset so it will be necessary to repeat the above steps. Under normal operation when
a person comes to load the machine it will not be necessary to manually reset the health control timer.
To test the health control sensor and make sure that the system is functioning properly do the following to
a machine that has been operating for at least one hour, note that is normally a two person operation.
Open the main and cold food doors.
Remove one half of the bottom tray.
Rotate the carrousel until you are able to reach the health safety sensor which is located in the lower left
hand corner of the cold food compartment extending out in front of the evaporator fan.
Close the doors and then vend the bottom selection on the cold food side.
Reach in and hold the probe in your hand to warm it above 45 degrees. Then remove your hand and allow
the door to close completely.
Try and vend another cold food compartment. When the message MAKE ANOTHER SELECTION is
displayed you know that the health safety switch has kicked out and will not allow another cold food vend.

%HOPPER SYSTEM OPERATION
This machine features a Shopper Mode Merchandising System. The rotation of the carousel is started by
pressing the “Press to View” bar located on the main door. This energizes the carousel motor relay, applying
power to the carousel motor. A cam on the motor allows the motor to turn 180 degrees which in turn rotates
the carousel 30 degrees (l/12 turn) or the equivalent of one small compartment width. When the bar is
depressed and held, the motor continues to rotate the carousel. The carousel is driven by a chain drive and
sprocket system.
NOTE: Should something cause the carousel to jam and stop rotating and the position of the carousel is such
that you can not remove a tray section follow this procedure. Located in the bottom of the machine on the far
left side is a piece of metal tubing with one end slotted. Reach over the top of the carousel and unscrew the
wing nut tension screw. Remove the chain from the large sprocket and then reverse the direction of the
carousel to remove the item causing the jam
~Carousel Alignment
~When installing the chain drive on the carousel it is very important that the carousel be aligned with the front
door of the machine. To align the front door with the carousel dividers, loosen the tension on the chain drive
enough to be able to move the chain one sprocket in the direction required to align the carousel and then
tighten the chain. Be careful not to over tighten the chain.
~Carousel Motor Assembly Adjustment
If the carousel motor is stopping prematurely or is not stopping at all it may be necessary to adjust the carousel
motor in relation to the stepping microswitch. Remove the top two tray halves in the carousel assembly. To
adjust the motor there are four hex headed screws on top of the carousel motor assembly. Loosen the four
screws and slide the motor to the left or the right to adjust it. Only a slight amount of movement is required
to change the adjustment. Then retighten the four screws and test the unit.
~BLOWER SYSTEM FOR COLD FOOD DOOR
L
~The blower system is designed to keep condensation from forming on the plastic delivery doors. The system
directs warm air across the delivery door from the right side and should be kept clean.

THEORY OF OPERATION
When inserting coins and the highest price set in the machine is reached, no additional coins will be accepted
by the changer. When inserting bills and the highest vend price set in the machine is reached the validator
will not accept any additional bills and the changer will not accept any coins.
By pressing a selection letter and number the control board will compare the price of that selection with the
credit accumulated and if there is enough a vend motor or a solenoid will be energized. When the vend is
completed the control board will then determine if any change is due and dispense the correct change from
the changer.
Should a vend motor fail to return to the home position in six( 6) seconds the control board will assume that
the motor is jammed. The control board will automatically take the selection out of service (remove it from the
machine configuration and inform the customer to “Make an Alternate Selection”. A jammed motor does not
affect any other selection in the machine. The selection that is jammed will be displayed on the digital display

ELECTRICAL SERVICE SECTION
MODES OF OPERATION
The system will operate in one of two modes, sales or service. On power up (after completing configuration),
the machine is in the sales mode. Service mode may be selected by pressing the mode button mounted on
the control board. The system will return to the sales mode if the mode button is pressed or after 25 seconds
of no service mode activity the control board will automatically return to the sales mode.
SALES MODE
In the sales mode, the control board will control the dispensing of products according to customer credit and
selection inputs. The control board will communicate with the coin mechanism and dollar bill validator (if
installed) so, as credit is entered it will be shown on the scrolling display. If there is inadequate change
available, the coin mechanism will indicate that an “Exact Change situation” exists and the control board will
show on the scrolling display “Please Insert Exact Money”.
When a customer makes a selection on the key pad, A thru H and (within 5 seconds) numbers 0 thru 9, the
accumulated credit will be compared to the price set for this selection and if credit is equal to or exceeds the
set price, the corresponding motor or solenoid will be energized. If the vend is successful the price will be
deducted from the credit value and the change returned. The vend will be considered unsuccessful if the motor
does not receive sufficient current or fails to reach the home position within (6) seconds.
On the cold food side the product delivery doors are locked by solenoids. When a vend is made, the lock which
allows the door to be opened is held open for 20 seconds, then it releases. If the door is not open the machine
will wait for an indication from the door switch that the door is open. After approximately five minutes the
machine will reset or it will automatically reset if the carousel is rotated.
SERVICE MODE
The service wde can be entered by pressing the “MODE BUTTON” located on the control board. By using
the numbers and letters on the alphanumeric key pad, the operator can program and review the features of
the control board. Upon pressing the mode button, will display any faulty motors, that have been detected
as bad or jammed and then removed from service by the control board.
