Manitowoc Foodservice developed this manual as a
reference guide for the service agent and installer of
fountain equipment.
Fountain dispensing is the serving of a beverage (soft
drink, tea, or juice, etc.) from a dispenser that will chill
the product to an acceptable serving temperature for
the consumer.
The beverage, delivery system and dispenser can be
postmix or premix. The system may be an elaborate
system with most of the components in the back of the
store and the dispenser in the front. Fountain systems
could be a simple system with the complete system
under the counter where the dispenser is located.
Our goal is that this manual will remove some of the
confusion, and mystery of beverage dispensing
equipment while providing a general overview of
service to the equipment.
Dispensing Basics
WHAT IS CARBONATION
Carbonation is the process of mixing carbon dioxide
gas into a liquid (water). The resulting liquid is called
soda water or carbonated water. The carbon dioxide
gas is the bubbles you see when a carbonated
beverage (like soda) is dispensed.
Most cola, lemon-lime products, etc. are carbonated.
Normally teas, juices, etc. are noncarbonated.
Some beverage technicians refer to noncarbonated
water as sweet water.
WATER CHARACTERISTICS
Water makes up over 80% of the typical finished
beverage. The quality of this primary ingredient is of
utmost importance. You should use regular cold tap
water, not water that has been through a water
softener, conditioner, etc. Any off taste or color should
be treated by proper water filtration.
STH14.book Page 10 Thursday, September 23, 2010 3:35 PM
Part Number STH14 9/10 11
WATER FILTERS
It is recommended that proper water filters treat the
water supply for the beverages. There are two basic
filters commonly in use.
1. Pre-filter, or sand filter. This filter removes any
foreign matter from the water down to 25 microns
in size.
2. Carbon or activated charcoal filter is also used.
This filter will reduce chlorine and other
chemicals, off-taste and odor. Some of the higher
quality filters may reduce organic compounds
(bacteria) in the water.
Do not use a filter containing any type of phosphate on
the beverage system. Phosphate as used for scale
reduction will cause the beverage to lose its
carbonation and become “flat” quickly.
WATER PRESSURES
Dynamic (flowing) water pressures to most
carbonators should be a minimum of 40 PSI
(1.38 bar). Water pressure to dispensers for
noncarbonated beverages should be a minimum of
50 pounds (22.7 kg). These pressures are minimum
operating pressures, not static pressure.
SYRUP BASICS
Your concentrated syrup containers should be stored
in a cool dry location that is easily accessible. Any
extremes in temperature can wreak havoc with the
quality of the product. For best results, the syrup
should be maintained in an environment between 40°
and 90°F (4.4° and 32.2°C).
STH14.book Page 11 Thursday, September 23, 2010 3:35 PM
12 Part Number STH14 9/10
PREMIX
Premix fountain dispensing consists of a container of
beverage ready for dispensing, beverage delivery
system, carbon dioxide (CO
2
) propellant, beverage
cooling system, and dispenser. We shall discuss each
component of this type of system within the context of
this manual.
The major advantage of a premix system over most
other types is its flexibility. This flexibility is the ability to
go anywhere. Many premix systems will operate
without electric power or separate water supply.
POSTMIX
Postmix fountain dispensing consists of either a tank
(called a Figal) or a box (called a Bag-in-Box) of
beverage syrup. The postmix system will also include
the carbonator, fresh water supply, carbon dioxide
(CO
2
) supply, syrup delivery system, beverage cooling
system, and dispenser. We shall discuss each
component of this type of system within the context of
this manual.
The major advantage of the postmix system over most
other systems is the very low cost of delivering a high
quality, fresh beverage to the consumer utilizing less
floor and storage space for the quantity of beverages
served.
PIPING
The fountain system is connected together by a series
of tubing or hoses. This tubing is called beverage tube
and is commonly available in 1/4" (0.64 cm), 3/8" (0.95
cm), and 1/2" (1.27 cm) inside diameters. Beverage
tubing is a flexible, high-pressure tubing. This tubing is
capable of withstanding system pressures in excess of
100 PSI (6.9 bar). The beverage tubing may be an
individual line or assembled with many lines of tubing
bundled together.
The beverage tubing is attached to the various
components of the system with barbed stems, nuts,
tees, etc. The tubing is held onto the fittings with small
tube clamps called stepless (Oetiker
®
) clamps. When
attaching the tubing and fitting to a “flared” fitting, the
use of a flare washer is required.
STH14.book Page 12 Thursday, September 23, 2010 3:35 PM
Part Number STH14 9/10 13
Several different types of tubing are available for the
beverage industry. If there is any possibility of the
tubing laying in a damp environment, the use of
non-permeable tubing should be used. Tubing is also
available as a single tube or bundled together. Single
tube is available as non-permeable plastic or stainless
steel. Bundled tube is available as plastic only.
Accessories
BAFFLE FOR MANITOWOC
®
ICE MACHINES
When installing a Manitowoc Ice Machine on a
dispenser, a baffle kit is required for proper installation.
The baffle kit is designed to prevent ice from lying
against the front of the ice machine, and melting down
the front of the dispenser. There are two different
baffle kits available for “S” series ice machines, one kit
is for the 30" (76.2 cm) wide machine, and the other kit
is for the 22" (55.9 cm) wide machine. There is also a
kit for “Q” series ice machines.
Kits are available through your local distributor. List
prices may be subject to change without notification.
Please call your local parts distributor for current
pricing before ordering.
NOTE: For full information about ice machine
installation, including plumbing lines connections and
electrical requirements, see the ice machine
installation manual.
MANUAL FILL LID FOR DISPENSERS
WITH AN ICE MACHINE
If you are top mounting your dispenser with an ice
machine, you will require a lid for the manual fill area
at the top, front of the dispenser.
If you ordered a dispenser and an ice machine at the
same time, the manual fill lid may be included with the
unit. The manual fill lid can be ordered from your local
distributor.
LEGS
Legs are optional equipment with most MBE
dispensers. Standard legs are 4" (10.2 cm) tall
stainless steel legs. We do not recommend using legs

Warning
Carbon Dioxide (CO
2
) displaces oxygen.
Exposure to a high concentration of CO
2
gas
causes tremors, which are followed rapidly by
loss of consciousness and suffocation. If a CO
2
gas leak is suspected, particularly in a small area,
immediately ventilate the area before repairing
the leak. CO
2
lines and pumps must not be
installed in an enclosed space. An enclosed
space can be a cooler or small room or closet.
This may include convenience stores with glass
door self serve coolers. If you suspect CO
2
may
build up in an area, venting of the B-I-B pumps
and/or CO
2
monitors must be utilized.

Water Supply
RECOMMENDED PLUMBING
The plumbing diagram is printed on a white vinyl label,
located above the inlet tubes for syrup and water. The
plumbing diagram label can be accessed by removing
the splash panel of the dispenser. The plumbing
diagram label explains which inlet coldplate fittings
supply which dispenser valves and water manifolds.
The water supply must first be connected to the
carbonator pump (not shown) before plumbing to
connection “A” shown on the plumbing diagram. The
carbonator pump deck must be within six feet (1.8 m)
of the dispenser for optimum performance. See the
B-I-B installation diagram for system pressure
settings.
NOTE: Valves are read from right to left.
A check valve must be installed in the water
supply line 3 feet (0.9 m) from the noncarbonated
water connection “PW”. Contact factory if not
installed.
Important
When installing cold carbonated (Internal Carb)
equipment, never put a tee for the plain water
connection in the line from the pump deck to the
cold plate. Putting a tee in the line will create
service problems and bad drink quality.
Important
When installing a CEV unit the lowest
recommended TDS reading for the water bath is
100 PPM.

Setting Pressures
PRE-MIX PRESSURES
Normal pre-mix pressure regulators must be set at
60 psi (4.14 bar). Diet pre-mix pressure regulators
must be set at 40 psi (2.76 bar). If you are
experiencing high foaming, decreasing the pressures
may correct the problem. Spitting and popping usually
requires slightly increasing the pressures. Pre-mix
beverage valve pressures vary by type and
manufacturer. Please consult the manufacturer of the
valves you are using for specific instructions regarding
operation of the valve.
COLD CARB AND AMBIENT SYSTEM PRESSURES
1. Incoming tap water — must be at a minimum
dynamic pressure of 40 psi (2.76 bar) and
maximum static pressure of 65 psi (4.48 bar)
(measured at inlet to pump).
2. B-I-B pressure gauge must be set for a minimum
of 60 psi (4.14 bar) or according to your line run.
3. Carbonator Pressure gauge (Use Preset
Regulator):
- Cold Carbonation set for 75 psi (5.17 bar).
- Ambient systems must be set at 90 psi to
105 psi (6.20 bar to 7.24 bar).
Important
If incoming water pressure is under 40 psi
(2.76 bar), a water booster is recommended. If
incoming water pressure is over 65 psi (4.48 bar),
a water regulating valve is required.

cycle. The refrigeration system
will operate until the low ice bank
probe pin and center ice bank
probe pin (black wire to the
control box) is covered by ice.
The third ice bank probe pin
(probe pin farthest from
evaporator coil) is the common or
ground pin. The common or
ground ice bank probe pin (green
wire to the control box) should
always be immersed in water and
never in ice of ice bank.
• Note: A delay circuit is built into
compressor and fan motor circuit.
Delay is (4) minutes (±20%) and
will prevent compressor start-up if
there is a power loss to the unit or
the compressor switch is in OFF
position and then placed in ON
position. Delay will also apply if
refrigeration cycle is stopped on
full ice bank and ice bank probe
sends a faulty signal to restart
refrigeration system within the (4)
minute delay time.

CHANGING NUMBER OF ACTIVE FLAVORS
To line up flavors with valves, note that valve outlets
number from left to right 1…2…3…4. Touch pad flavor
tab is numbered as shown below. Connect vinyl tube
from outlet 1 and dispense with flavor tab 1, etc.
The current Flavor Magic control board is set up in the
4 flavor default mode. This mode will handle all
dispensing situations whether 3 or 4 flavors are used.
Some early boards were set up as default in the 3
flavor mode. If the customer desires to add another
flavor for a total of 4, proceed as follows:
1. Power down the circuit board by disconnecting
the 24 volt connector in the lower left hand side of
the board. “24VAC” is imprinted on the board next
to the pin connection.
2. Wait a minimum of 10 seconds.
3. Power up the board by connecting the 24 volt
connector.
4. IMMEDIATELY (within 5 seconds) press and hold
the “PROG” button down.
5. After a few seconds, the number “4” will appear
on the display.
6. Release the “PROG” button. The board will cycle
the display from “Pro” to
“4……3……2……1……0” and then to “- - - -”.
7. The circuit board is now enabled to dispense the
4th flavor. The 4th flavor button is the top middle
button.

8. A flavor tab for the 4th flavor will have to be added
to the touch pad. To do this, obtain one (1) P/N
5030780 20 flavor decal pad. Remove the P/N
5031579 decal overlay and add the 4th flavor tab
as well as replace any flavor tabs which came off
when removing the decal overlay. Note position of
4th flavor on the touch pad in the picture and
placed tab where indicated. Obtain a new P/N
5031579 decal overlay and place over the tabs.
If the customer decides to go back to 3 flavors, it will
not be necessary to change the board back to 3
flavors. However, it can be done by following steps 1
through 6 above. The number “3” will appear on the
display. Then disconnect the number “4” syrup from
the system, remove the 5031579 decal overlay,
remove the flavor tab “4” and replace the 5031579
decal overlay. It would be a good idea to have an
additional P/N 5030780 in case flavor tabs are
damaged in the process.
STEADY OR FLASHING TOUCH PAD LED
The blue LED on the touch pad can be set to one of
two display modes:
1. Steady illumination. This is the default mode and
the LED will remain on steady until dispense is
activated. The light will flash only when product is
being dispensed. In this mode, the control board
display will read “Off”.
2. Flash mode. The LED will turn on for 1/2 second
and off for 1/2 second.
Enter the Flash mode by pressing the program button
until a flashing “- - - -” is displayed. Pressing flavor
button 1 (far left button) will switch from “Off” (default)
to “On”. The LED will now flash. To change back to the
default simply press flavor button 1 again and the
display should read “Off”. Press program button to exit
to the next program function.

The timer is non-adjustable and is set to agitate the ice
for 3 seconds every 3.5 hours. Activating the
dispenser will reset the timer. After 3.5 hours of
non-use, the timer will energize the dispenser motor.
The LED tells the technician in which mode the timer is
operating. Rather than a jumper pin, this timer has a
female spade connector that must be connected to
terminal number 6.
When this jumper is in place, the LED will blink at
one-second intervals, this is the run mode.
When the jumper is open, the LED will flash every
0.4 second. This is the test mode and the timer will
cycle every 55 seconds in test mode. If the timer is left
in test mode, it will automatically reset to run mode.

Component Specifications
Electrical Requirements
Refer to Ice Machine Model/Serial Plate for voltage/
amperage specifications.
VOLTAGE
The standard voltage for S/SV/SVI/NGF/FRP Series
dispensers is 120VAC-60Hz. A power cord is provided
with 120VAC-60Hz models only. S/SV/SVI/NGF Series
dispensers use a 1/7 hp gearmotor.
Minimum Circuit Ampacity
The minimum circuit ampacity is used to help select
the wire size of the electrical supply. (Minimum circuit
ampacity is not the beverage/ice machine’s running
amp load.) The wire size (or gauge) is also dependent
upon location, materials used, length of run, etc., so it
must be determined by a qualified electrician.
!
Warning
All wiring must conform to local, state and
national codes.

140 Part Number STH14 9/10
Minimum Circuit Amperage Chart
NOTE: For FlexTower applications — A dedicated
120 VAC, 15 ampere circuit is required to provide
power to the power supply’s transformer with an
output of 24 VAC for the electric valves, 120 VAC,
8 ampere circuit, and to power a cold water
recirculation pump. The power supply has a 120 VAC
outlet to provide power for the cold water recirculation
pump.

Grounding Instructions
This appliance must be grounded. In the event of
malfunction or breakdown, grounding provides a path
of least resistance for electric current to reduce the risk
of electric shock. This appliance is equipped with a
cord having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
!
Warning
The beverage/ice machine must be grounded in
accordance with national and local electrical
codes.
!
Warning
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
The conductor with insulation having an outer
surface that is green with or without yellow stripes
is the equipment grounding conductor. If repair or
replacement of the cord or plug is necessary, do
not connect the equipment-grounding conductor
to a live terminal. Check with a qualified
electrician or serviceman if the grounding
instructions are not completely understood, or if
in doubt as to whether the appliance is properly
grounded. Do not modify the plug provided with
the appliance — if it will not fit the outlet, have a
proper outlet installed by a qualified electrician.

Warning
When using electric appliances, basic precautions must
always be followed, including the following:
a. Read all the instructions before using the
appliance.
b. To reduce the risk of injury, close supervision
is necessary when an appliance is used near
children.
c. Do not contact moving parts.
d. Only use attachments recommended or sold
by the manufacturer.
e. Do not use outdoors.
f. For a cord-connected appliance, the
following shall be included:
• Do not unplug by pulling on cord. To
unplug, grasp the plug, not the cord.
• Unplug from outlet when not in use and
before servicing or cleaning.
• Do not operate any appliance with a
damaged cord or plug, or after the
appliance malfunctions or is dropped or
damaged in any manner. Contact the
nearest authorized service facility for
examination, repair, or electrical or
mechanical adjustment.
g. For a permanently connected appliance —
Turn the power switch to the off position
when the appliance is not in use and before
servicing or cleaning.
h. For an appliance with a replaceable lamp —
Always unplug before replacing the lamp.
Replace the bulb with the same type.
i. For a grounded appliance — Connect to a
properly grounded outlet only. See
Grounding Instructions.

Pump Deck Wiring
The supply cord is equipped with a three prong 5-15P.
When a Ground Fault Circuit Interrupter (GFCI) is
required by code, a breaker type protector must be
used. We do not recommend GFIC outlets as they are
known for more intermittent nuisance trips than panel
breakers. To ensure both the safety and proper
operation of this equipment, be certain that the
electrical receptacle is a proper design so as to accept
this plug, ensuring that the carbonator assembly is
properly grounded.
If the pump deck is to be installed in an area or
community whose local codes require permanent
wiring, the following procedure must be followed.
1. The three wires (white, black and green) must be
fed through the cable connector and brought into
the wiring compartment. The cable must be
secured into the connector.
2. The green wire from the cable must be connected
to the green screw that attaches to the inside
panel of the wiring compartment. Be sure to use a
ring torque terminal for connecting the wire to the
screw.
3. The white wire from the cable must be joined to
the N terminal of the liquid level control board by a
suitable U.L. listed insulated cable connector.
The black wire from the cable must be joined to the L1
terminal of the liquid level control board by a suitable
U.L. listed insulated cable connector.

Water Supply
RECOMMENDED PLUMBING
The plumbing diagram is printed on a white vinyl label,
normally located above the inlet tubes for syrup and
water. The plumbing diagram label can be accessed
by removing the splash panel of the dispenser. The
plumbing diagram label explains which inlet coldplate
fittings supply which dispenser valves and water
manifolds.
The water supply must first be connected to the
carbonator pump (not shown) before plumbing to
connection “A” shown on plumbing diagram. The
carbonator pump deck must be within six feet (1.8 m)
of the dispenser for optimum performance. See B-I-B
installation diagram for system pressure settings.
NOTE: Valves are read from right to left.
A check valve must be installed in the water
supply line 3 feet (0.9 m) from the noncarbonated
water connection “PW”. Contact factory if not
installed.
