1 INTRODUCTION
The Unicorn Hygienics ‘Multivend’ coin operated electronic vending dispenser is a
wall-mounted unit able to handle up to ten separate product lines of cartoned stock in a
‘book-shelf’ arrangement. The dispenser is available in original white ABS plastic or steel
white or silver.
Each identical shelf can be adjusted to cater for the packet size or shape used in the
machine. On each shelf packets are spring-loaded to the rightmost end. A successful vend
request and coin validation sequence by the user causes a motorised escapement on the
appropriate shelf to eject one packet into the drop-chute, to fall past the security flap for
collection by the user from the product bowl at the base of the dispenser.
1.1 Dispenser operation
The all-electronic Unicorn Hygienics coin validation and dispenser operating system is
powered by a replaceable battery power pack. Dormant until activated by either a coin
entry or button press, it can identify up to five different programmed coin types.
The system drives an LCD (liquid crystal display) information screen above the coin entry
point to display vend prices, validated coin totals and helpful messages to the user.
Vend prices can be set from zero price (free-of-charge) upwards, and are easily revised by
using the Multivend desktop app.
When a coin is successfully validated, the LCD total is immediately updated.
Non-accepted coins fall directly into the product bowl at the base of the machine for easy
retrieval. All validated coins will drop straight into the cash box and these won´t be able to
be refunded.
If an out of stock product is selected the LCD briefly flashes ‘Out’.
The refund button may be used to abandon any operation, however all validated coins
won´t be refunded.
If the validated coin total exceeds the price of a pack vended the ‘excess’ coin value is lost
to the user.
When the Power pack is nearly exhausted the display reads - Lo - below the vend price, and
the system will continue to operate for a while. Thereafter it will read SERVICE as well as -
Lo - and will not vend products to allow the machine to conserve battery power whilst
remaining in its dormant state. Any coins entered are returned automatically to the user.

1.3 Installation
1.3.1 Tools required
➢Two speed hammer drill
➢No. 12 masonry bit
➢Flat blade screwdriver suitable for No. 12 screws
➢4mm and 2.5 mm hex socket screw drivers
➢Spirit level suitable for horizontal and vertical use
➢6ft or 2m tape
1.3.2 Kit supplied with dispenser
➢Power pack
➢Fixing brackets - 2 off (plastic m/c only)
➢Masonry plugs No. 12 - 4 off
➢Steel fixing screws No. 12 x 2” pan-headed slotted (NOT Pozidrive) - 4 off
➢Steel hex socket cap M5 x 10 security screw - 1 off
➢Packing washers 3mm thick - 2 off

1.3.3 Locally supplied fittings
➢For fixing to wood or plasterboard walls - suitable butterfly fasteners
➢For fixing to stepped walls (half tiled) - scrap hardboard equal to the step difference
1.3.4 Location
Select a suitable prominent site. A conspicuous location discourages misuse. Take care not
to obstruct access to other fittings, door opening arcs etc.
Choose a strong masonry wall if possible. The installation must be strong enough to
prevent the dispenser from being pulled away from the wall in the event of vandalism or
misuse. If the customer’s chosen site is unsuitable, explain the problem and suggest a
more appropriate alternative.
1.4 Installation procedure
1.4.1 Unpacking the dispenser
Remove the dispenser and all other parts from the packing case. Lay the unit on its back
on the floor. Use your master key to unlock and open the door. The key turns clockwise
180° to unlock, anti-clockwise to lock.
1.4.2 Locating the lower bracket on the wall (Fig 1-1 for plastic m/c only)
The plastic dispenser is attached to
the wall by two identical metal
brackets, allowing the machine to be
later removed / replaced simply by
removal of a security screw.
Mark the position of the lower bracket
on the wall as shown in Figure (1-1).
Mark the position of the left mounting
hole through the bracket peg, and drill
and plug this hole. Using a No. 12
screw provided loosely attach a
bracket to the wall, level the bracket,
and mark the right screw position.
Drill and plug the right hole and insert
the second screw. Tighten both
screws to secure the lower bracket to
the wall.
1.4.3 Positioning the upper bracket
(plastic m/c only)
Raise the top of the dispenser, put the
upper bracket in from behind and fully
engage the two mushroom-headed

diecast pegs into the top of the diecast “Keyhole” plates. Insert and tighten the socket cap
security screw from inside the dispenser through the central hole above the top shelf. Pick
the dispenser up and locate it on the lower bracket, ensuring both pegs are fully engaged.
Use the spirit level to ensure that the unit is exactly upright, then without moving it
carefully mark the position of the two upper bracket holes on the wall from inside the
dispenser through the diecast mounting peg holes (use a scribe or long thin pencil etc.).
Take the machine down from the wall, leaving the upper bracket secured in the case. Drill
and plug the two upper mounting points, then use a centre-punch or ball-point pen to
open-up the two plugged holes for easy screw entry. Lift the dispenser onto the lower
mounting bracket again and push it firmly down to fully engage the two pegs. Insert the
two securing screws from inside the machine through the upper bracket holes into the wall
plugs, and fully tighten them.
1.4.4 Fastening the dispenser to the wall (Fig 1-1 for metal m/c only)
The metal dispenser is attached
directly to the wall by four masonry
screws, inserted through the body of
the machine. This procedure should
be carried out by two people, as the
weight and size of the empty
dispenser may exceed statutory
guidelines for a single person.
Scribe the intended vertical centre-
line of the machine on the wall, and
mark a position 45mm (1 ¾”) from
the top. Drill a hole at this position
to accept a screw about 25mm (1”)
long (not supplied), plug the hole
and insert the screw until the head
is about 8mm (3/8”) clear of the wall.
Pick the machine up and hang it on
this screw with the head through
the small triangular hole at the top
in the back.
Holding the machine exactly upright,
mark the four mounting screw
positions on the wall through the
holes in the back of the dispenser
cabinet. These should be in a
rectangular pattern 320mm (12 5/8”)
apart horizontally and 900mm (35
7/16”) apart vertically. Remove the machine, drill and plug all four holes, then use a
centre-punch or ball-point pen to open them up for easy screw entry.

Hang the dispenser back up on the wall with the first screw through the triangular hole
again, insert the four mounting screws through the corner holes in the back of the cabinet,
and tighten them securely.
1.4.5 Establishing accurate mounting
Check the action of the door and lock. It is essential that it closes cleanly without lifting or
twisting. If any misalignment is seen this is probably caused by an uneven wall, and you
may need to take the dispenser down to pack one of the mounting points away from the
wall. Repeat this step until the door closes satisfactorily.
1.4.6 Securing the dispenser (plastic m/c only)
Check that the security screw is
tightly in place, and that the
dispenser cannot be wrenched
upwards off the brackets -
particularly the unsecured lower
one. Replace the money box.
1.4.7 Loading the dispenser
Fill all the shelves with the
appropriate products.
Note that tuck-in cartons
have one good folded edge
and the tucked-in side “open”
for finger access. Put the
smooth folded edge as the
right rear corner for the cam
to push against.
1.4.8 Installing the Power Pack
Remove the rightmost battery strap screw in the door, put the Power Pack in the cradle
with the label towards you and the lead at the bottom. Do NOT connect the power pack.
Replace the battery strap and re-tighten the screw.

2 MACHINE CHECKING PROCEDURE
2.1 General
Check thoroughly through the dispenser to ensure that all the packs are correctly settled
on their respective shelves, and all loom wiring and system parts appear to be correctly
fitted. Do NOT touch any electronic board surfaces or wire ends with your bare hands or
tools as electrostatic discharge between you and any part of the electronic system can
easily destroy sensitive components.
2.2 Powering-up
Attach the Power Pack lead to the connector below it on the back of the Multivend
Controller board. The dispenser will power-up immediately.
2.3 Checking for basic operation
Press each product button in turn to check that all prices displayed by the LCD correspond
to the price card adjacent to the button.
Refer to Section 3 to resolve any unexpected responses until the dispenser performs as
expected.
2.4 Testing all the shelves
You should now check the correct action of every shelf by pressing each product button
and then inserting the right amount in turn and observing the corresponding shelf dispense
one pack. If any problems occur refer to Section 3 and then repeat these tests.
2.5 Coin system testing
Put at least three coins of every currently available national denomination into the coin
slot and check that the coin validation system and totalised value shown on the LCD
responds appropriately –Please note the product needs to be selected before the coins are
inserted or otherwise the coins will be refunded. You should expect on average eight or
nine out of ten coins to be accepted by the system. It is likely however that dense round
coins (e.g. £1) will be more reliably validated than light ones or heptagonal ones (e.g. 20p).
You may carry out these tests with the door open. Note that any rejected coins or
validated coins cashed or refunded by the escrow will drop onto the floor unless you place
your hand or a suitable receptacle underneath.
If the system performance is not acceptable refer to Section 3.
2.6 Final vend checks
Close the door and using appropriate coins, vend one pack of each product. When this has
been completed open the door, replace all the vended packs on their correct shelves and
retrieve your coins. You have now completed the thorough checks necessary to establish
that the dispenser is functioning correctly, and in the case of a new installation the unit is
now ready for hand-over to the owner.

2.8 Customer hand-over
Demonstrate the operation of the dispenser to the customer as follows -
➢Start with the door closed and locked. Show that each product button produces the
correct vend on the LCD, press a button and then insert some coins to vend at least one
pack.
➢Show that the key turns the lock clockwise 180° to unlock and is then trapped until the
lock returns to the ‘locked’ position.
➢Demonstrate how refill packs should be placed on the shelves to the right of the
spring-return red levers and show how to retrieve coins from the money box. Replace
the money box, shut and lock the door.
3 TROUBLE SHOOTING AND REPAIRS
3.1 Useful tools
➢Master key
➢Pozidriv #1 screwdriver –preferably magnetised
➢3mm (1/8”) flat blade screwdriver
➢Engineers and Fine nosed pliers
➢Tube of Super-glue
➢Silicon Spray
3.2 Fault identification
Problems with the dispenser will generally fall into one of these two areas:
➢Electronic system - failure to wake up, recognise or totalise coin values properly, or to
route power to the shelves to deliver packets.
The cause will often be resolved without spare parts –i.e. a loose electrical connector
requires re-connection, otherwise a system component may have failed and require
replacement. In all such cases it is extremely important to check through the system in
an orderly and logical way to determine the primary cause of the failure to operate,
because a fault in one component can easily prevent another fully operational part
from functioning correctly and thus appear faulty itself.
➢Mechanical hardware - coins are accepted and totalised and the shelf motors function
but the dispenser fails to deliver packs, or obvious physical damage must be repaired.
In these cases it is much more likely that the fault will be localised and easily identified,
and the use of spare parts to replace faulty hardware will be straightforward and
obvious.

NOTE!
***The electronic system is fairly robust and resistant to abuse, but you should never
touch the components or bare wires even when they are disconnected and/or removed
from the dispenser as this may allow electrostatic discharge (ESD) to corrupt stored data or
even destroy a component. ***
Whilst removing or replacing any parts of the electronic system it is good practice to keep
the Power Pack plugged-in as this may help to ‘earth’ the system and minimise ESD
problems.
