THEORY OF OPERATION
•
•
The FlavorFusion®/FlavorOverload machine is an above counter ice/beverage unit with multi flavor
nozzles and the capability to inject bonus flavors into the finished drink.
The beverage is cooled via ice melting on an aluminum cold plate. Ice is kept on the cold plate by
means of an opening in the hopper that drops ice onto the surface during agitation of the ice in the
hopper.
•
•
The unit contains a mechanical ice chute and gate mechanism.
The ice agitation gear motor is removable from the gear box to ease removal of the motor during ser-
vice and lower repair cost.
•
•
The unit has six nozzles for dispensing brand and bonus flavors.
Each brand nozzle serves four discreet flavors fed by four syrup valves, one plain water, and one carb
water valve. Every position is flexible for use with either carb or non-carb water.
•
Each bonus nozzle serves four individual flavors intended for injection into the finished drink. Bonus
nozzles are fed by four syrup valves only. There is no option to dispense water out of the bonus nozzle
without significant plumbing changes.
•
•
Bonus flavors require a separate regulator setting on their BIB pumps (20 psi maximum).
Brand and bonus flavors are controlled by means of six interface boards (one interface board per noz-
zle). The interface boards are common for each nozzle. Valve positions are configured on the mem-
brane switch. No special tool or PDA is required.
•
•
Valve flow rates are adjustable for 3.0-3.75 oz/sec finished drink dispense rate.
Unplug the unit or turn off the key switch before attempting any electrical service on the unit, failure to
do this can cause damage to the electrical components!

PROGRAMMING
NOTE: The programming mode is exactly the same for both brand and bonus keypads.
To enter the programming mode, press and hold the two program buttons (see FIGURE 3) at the top of
the keypad for approximately 4 seconds. All keypad LEDs will flash off for approximately 1 second to
indicate the start of the programming mode.
To exit programming mode, press and hold the two program buttons for approximately 4 seconds. All
keypad LEDs will flash off for approximately 1 second, resuming normal operation mode.
Programming Mode Flashing Sequences
Once in programming mode, each dispense button LED flashes in a sequence cycle according to one (1)
of six (6) dispense types. For Brand Keypads, only dispense types 1 and 2 should be used. For Bonus
Flavor Keypads, dispense types 3 through 6 are used. The six (6) dispense types are described below,
and shown in a timing diagram in FIGURE 1:

Setting the water flow rate will require a timed dispense. To accomplish this, the following procedure
should be followed:
1.
Enter programming mode for the valve
block by simultaneously pressing and
holding both programming buttons for 4
seconds (see FIGURE 3). The LED’s for
flavors 1-4 should flash off and then back
on. The drink icon should turn off.
2.
3.
4.
Set the valve block to a 4 second pour
mode by simultaneously pressing and
holding Flavor 1 and Flavor 4 buttons until
the flash pattern for all four buttons
changes.
Flow Adjuster Detail
(Water)
Place an empty ratio cup under the
appropriate nozzle and press the left
program button for a 4 second dispense of
carbonated water. There should be
approximately 10 oz. dispensed.
If necessary, adjust the water flow control
(see FIGURE 2), empty ratio cup, and
repeat step 3. Otherwise empty ratio cup
and repeat step 3 using the right program
button for plain water.

Setting a Button to Dispense Non-carbonated Water Only
1.
Program the designated button to dispense non-carbonated water (see Programming Mode.)
2.
Do not connect a syrup source to the inlet circuit of the designated button (1-14 or A1-A2.) If circuit
1 through 14 is chosen leave the coldplate inlet circuit plugged with the red cap. If circuit A1 or A2 is
chosen, plug the end of the inlet tube with a red cap from the coldplate, or with tape.
Setting a Button to Dispense Carbonated Water Only
1.
Program the designated button to dispense carbonated water (see Programming Mode.)
2.
Do not connect a syrup source to the inlet circuit of the designated button (1-14 or A1-A2.) If circuit

TROUBLESHOOTING
IMPORTANT: Only qualified personnel should service internal components or electrical wiring.
WARNING: If repairs are to be made to a product system, remove quick disconnects from the
applicable product tank, then relieve the system pressure before proceeding. If repairs are to be
made to the CO2 system, stop dispensing, shut off the CO2 supply, then relieve the system
pressure before proceeding. If repairs are to be made to the electrical system, make sure
electrical power is disconnected from the unit or the key switch has been turned off.
Should your unit fail to operate properly, check that there is power to the unit and that the hopper
contains ice. If the unit does not dispense, check the following chart under the appropriate symptoms to
aid in locating the defect.

Symptom
Cause
Remedy
1
Bonus Flavor Icon and/
or Drink Icon LEDs (see
FIGURE 3) are ON
continuously with four
quick flashes every 30
seconds.
A. This indicates a poor
connection in the lighting
synchronization harness
that connects the interface
boards together.
A. Turn the keyswitch to disconnect
power to the interface boards. Check the
electrical connections between the
harnesses that interconnect the right
side of all interface boards together. Turn
back the keyswitch to reconnect power.

Bonus Flavor Icon and/
or Drink Icon LEDs (see
FIGURE 3) are not in
sync with the lighting

B. This may result over time
as the lighting sequence

can become slightly out of
synchronization.
B. Unplugging the unit and performing a
power up will re-synchronize the lighting
sequence.

not working
A. Poor connection between
interface board and keypad

A. Turn the keyswitch to disconnect
power at the interface boards. Check
harness connections at each interface
board.
B. Keypad LED's are burnt
out
B. Turn the keyswitch to disconnect
power at the interface boards. Unplug
the ribbon cable from one interface
board and test it by plugging it into the
neighboring interface board. If the
keypad still doesn't light up replace the
keypad PCB.
C. Interface board is
defective.
C. Turn the keyswitch to disconnect
power at the interface boards. Unplug
the ribbon cable from one interface
board and test it by plugging it into the
neighboring interface board. If the LED's
light up the interface board is defective.
Replace the interface board.
D. Corrosion at connector
between keypad and ribbon
cable.
D. Replace keypad circuit board and
ribbon cable.
E. Main control board is
defective.
E. Replace the main control board.

During standby mode,
the brand and bonus
LED icons do not
alternate back and forth
- instead they light
together.
Bonus buttons are
incorrectly programmed as
brand buttons, or vice versa.
Check the programming of each keypad
and set each button as CW, PW, or
timed dispense based upon the flavor
lineup.
Contact your local syrup or beverage equipment distributor for additional information and troubleshooting
of beverage system.

THIS IS AN ERROR
CONDITION.
- Check electrical
connections at the
carbonator tank, and at
connector J4 on the main
control board
- Black wire should be
connected to the LOW
probe and also to Pin 4 of
Connector J4
- Reverse the connections
if incorrect
- Replace harness if
necessary

Poor signal connection to
the carbonator tank. May
result in short cycling of the
carbonator pump.
