GENERAL INFORMATION
This manual contains programming, operation, and complete parts and electrical wiring
diagrams.
The V21 controller is a microprocessor which will permit pricing per selection from 0.00
to 99.99. This machine also has space-to-sales programming as well as energy savings
modes.
*Dimensions and shipping weight will vary slightly due to manufacturing tolerances,
shipping boards and whether or not coinage is installed.
** 20 oz. PET capacity may vary based on the shape and size of the bottle.
***12 oz. can capacities are listed using a 4-deep set up.

INITIAL SET-UP
A. UNPACKING
Remove all plastic film, cardboard and tape from the outside of the vendor. Loosen any
shipping devices used to secure interior parts during shipment (backspacer, shims or
spacers).
To remove shipping boards from base, raise vendor on a well-stabilized lifting device.
Remove the leveling bolts which hold the boards in place and remove the boards. Re-
place bolts to equal heights in the threaded holes. Another method to remove shipping
boards is to split the boards apart. Using a pinch bar or a heavy screwdriver and ham-
mer, insert tool into the slots and force the boards apart. The leveling legs shall not
raise the vendor more than 1 1/8 inch above the ground.
B. POSITIONING
IMPORTANT: PLACE THE VENDOR IN DESIRED LOCATION AT LEAST THREE TO
FOUR INCHES (7.6CM TO 10.2CM) AWAY FROM ANY REAR OBSTRUCTION. This
is for proper air flow through the refrigeration compartment. The refrigeration system
requires rear to front air circulation for proper operation.
C. POWER SUPPLY CONNECTION
CAUTION: DO NOT USE AN EXTENSION CORD!
The vendor’s power requirements will vary depending upon the country it was pur-
chased for. To verify the power requirements of the vendor, check the serial plate lo-
cated on the hinged side of the outer door (see Figure 4 on page G-4). The power
requirements are listed on the serial plate.
To insure safe operation of the vendor, the vendor’s power supply must be a properly
grounded and polarized outlet. Before plugging the vendor into the outlet, test the outlet
to confirm it will meet the vendor’s power requirements. If the power supply of the outlet
is different from the power requirements of the vendor, a transformer may be necessary.
If the power requirements are not properly met, contact a licensed electrician and have
the necessary correction made.
Should you require additional information, contact the Technical Services Department of
the SandenVendo America, Inc. office in your area.

NOTE: The Model number of the vending machine is located on the top, left hand corner of
the serial plate. Do Not use the “BASIC UNIT” number. The BASIC UNIT number is the
cabinet size, which is used on a number of different machines. A typical model number could
read “721TDD00029”. The 721 is the model number, TDD represents the product line of the
vendor, and the remaining digits tell what options are included.

COIN INSTRUCTION LABEL & PRICE LABEL APPLICATION:
Apply labels to a clean and dry surface. Peel backing from label and apply with firm,
even pressure.
INSTRUCTION LABEL
(Refer to Figure 2 for the following information.)
Coin insert “A” has a separate validator opening, and insert “B” shows the validator
opening built into the coin insert. Apply instruction label to area shown (as needed by
the vendor).
FLAVOR LABELS INSTALLATION:
In Figures 3 & 4, corresponding styles are indicated by A, B, C, D, or E notations.
Insert flavor labels to the side or top of selection window or button depending on the
style. See Figure 3 for selection style. Rear views of windows and buttons are shown
in Figure 4. Arrows point the direction to insert labels.
Selection window and selection button labels identify product contained in columns.

ALIGNMENT CHECKS
REFRIGERATION AREA CHECK:
Check the position of the condensation pan (see Figure 5). The correct position of the
pan is on the right hand side of the vendor with the ramp of the pan just outside the
right hand air dam. Be sure the drain tube is attached to the pan and is free of kinks. A
water trap is installed into the condensation pan and will prevent warm, moist air from
reaching the evaporator area.
LOADING INSTRUCTIONS
BASIC LOAD SET-UP (see Figure 6 on next page):
The V21 machine is capable of vending a variety of products. For specific information,
refer to the product set-up label on the machine inner door or contact the Technical Ser-
vices Department of the SandenVendo America, Inc. office in your area.
Load product evenly. Product is to be loaded differently depending on the type of
product being vended. Use the directions in Figure 6 in the PRODUCT LOADING
section to determine how to load a specific product.
To maintain the integrity of the stack, never move a vending machine when it is loaded.

V21 PRODUCT SETUP AND LOADING INSTRUCTIONS
1
FOLLOW THE 3 STEPS BELOW WHEN SETTING VENDOR UP FOR A PRODUCT
BACK SPACER
Adjust the back spacer to provide approx. 1/4" to 1/2" gap
between the front spacer, product and back spacer.
2
PRODUCT STEP
For short product vending, move the product step
to the "FORWARD" position.
For tall product vending, move the product step
to the "BACK" position.
3
DEPTH SETTING (ELECTRONIC CONTROL MODE)
The "DEPTH SETTING" for each column must correspond to the number of products in the column.
For example; the depth setting for a column vending double depth bottles must be set to "2", and
a column set to vend quadruple depth cans must be set to "4".
Refer to the VEC 12 programming instructions for details on how to access and change the depth setting mode.

SMALL DIAMETER PRODUCT SETTING
Small diameter products (less than 2.5" Ø) such as 500 ML water bottles require the use of side spacer PN 1122928.
2.5" Ø OR LESS
Small diameter 250 ML energy drink cans (2.1" Ø) require the use of conversion kit PN 1121638.
For questions regarding product settings, contact the Vendo Technical Services Department at
1-800-344-7216 ext.3368 (US/Canada) or 559-439-1770 ext.3368.

VEND MECHANISM PARTS DESCRIPTION
The parts listed below are part of the vend motor mechanism (refer to Figure 7 on page
G-9). One mechanism is required per column, except the drop sensor assembly, which
is one assembly per machine. The parts are interchangeable. Setting will differ between
single, double, triple, and quadruple depth.
VEND MOTOR ASSEMBLY: P/N 1122820
The motor is attached to the mech plate by two screws.
VEND BUCKET: P/N 1122815
The vend bucket holds the product(s) in a “ready to vend” position at the base of each
column.
MOTOR COUPLING CAM: P/N 1122817
The coupling cam couples the motor to the bucket. It is located behind the motor, on the
motor shaft. It is also a means to provide feedback to the controller to determine when
the motor has reached maximum clockwise and counterclockwise positions.
GATE: P/N 1122871
The gate holds product above the vend bucket.
GATE LINK: P/N 1122819
The rotation of the coupling cam moves the gate link. This opens the gate, allowing one
layer of product to drop into the bucket.
CAN STEP: P/N 1122856
The can step is located at the bottom of the stack partition. It is pulled forward when
vending cans and is moved back for bottle vending.
REAR BUSHING: P/N 1122816
The rear bushing provides a low friction pivot for the rear of the bucket.
FRONT SPACER: P/N 1122814
The front spacer helps to guide product into the bucket.
DROP SENSOR ASSEMBLY: P/N 1122923
The drop sensor assembly is located below the delivery chute. When a product is vended,
the drop sensor senses the impact, and cancels the credit.

VEND CYCLE
Several operations take place during the vend cycle: When a selection is made, the
coupler and bucket rotate, product is dispensed and the bucket is then reloaded.
The sequence of these operations change slightly when the column’s depth setting
is changed. With the single depth setting, one purchase is made and the bucket is
reloaded. With the double depth setting, two purchases are made before the bucket is
reloaded. With the triple depth setting, three purchases are made before the bucket is
reloaded. With the quadruple depth setting, four purchases are made before the bucket
is reloaded. (See Figures 8 & 9)
