Installation and Service Manual
SAFETY
IMPORTANT SAFETY INSTRUCTIONS
Carefully read all safety messages in this manual. Learn how to operate the FlexTower unit properly.
Do not allow anyone to operate the unit without proper training and keep it in proper working condition.
Unauthorized modifications to the FlexTower may impair function and/or safety and affect the life of
the unit.
CARBON DIOXIDE WARNING
DANGER: Carbon Dioxide (CO2) displaces oxygen. Exposure to a high concentration of CO2 gas
causes tremors, which are followed rapidly by loss of consciousness and suffocation. If a CO2 gas leak
is suspected, particularly in a small area, immediately ventilate the area before repairing the leak. CO
lines and pumps should 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 CO2 may build up in an area, venting of the B-I-B pumps and / or CO2 monitors should be utilized.
QUALIFIED SERVICE PERSONNEL
WARNING: Only trained and certified electrical and plumbing technicians should service this unit.
All wiring and plumbing must conform to national and local codes.
2
SHIPPING, STORAGE, AND RELOCATION
CAUTION: Before shipping, storing, or relocating this unit, syrup systems must be sanitized. After
sanitizing, all liquids (sanitizing solution and water) must be purged from the unit. A freezing environment causes residual sanitizing solution or water remaining inside the unit to freeze, resulting
in damage to internal components.
INSTALLATION WARNING
WARNING: The splash panel must remain in place for installation because the splash panel pro-
vides structural integrity to the unit. Do not remove the splash panel until after the unit is installed.
ADDITIONAL WARNINGS
Installation and start-up of this equipment should be done by a qualified service technician. Operation,
maintenance, and cleaning information in this manual are provided for the user/operator of the equipment.
Save these instructions.

Installation and Service Manual
SAFETY
GROUNDING IN STRUCTIONS
WARNING: Risk of electrical shock. Connect to a properly grounded outlet only.
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.
DANGER – 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 should always be followed, including the following:
a) Read all the instructions before using the appliance.
b) To reduce he 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. Return appliance to 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 Ground-
ing Instructions.

INSTALLATION
SURVEY
Prior to installation, a location survey is highly recommended to assure there is sufficient room for the FlexTower on
the counter, for the BIB rack in the back room, and room to route the beverage tubing from the BIB rack.
If an ice drink dispenser heat exchanger is used, assure that the ice drink dispenser is in close proximity to the
FlexTower area so the heat exchanger can be easily routed to the tower to provide cold water for the finished
beverages. Other methods of cooling the water are available. Contact your Manitowoc Beverage Equipment distributor for details.
Assure that a 115 Volt, 15 amp electrical outlet is available to provide power for the FlexTower and the water pump.
A separate outlet is recommended for each component
Assure that a ¾”( 2 cm) water line with a shut off valve is available in close proximity to the FlexTower. Water
treatment is highly recommended to assure a quality finished beverage. Minimum water pressure is 40 PSI (2.75
BAR) dynamic and maximum is 80 PSI (5.5 BAR) static.

INSTALLATION
PRECHILL COIL RETROFIT KIT
1. Disconnect or shut of power, water supply to ice
maker or makers (1A) and power supply to ice beverage dispenser (1B) (See Figure 1). Failure to
do so may cause electrical shock or injury.
2. Ice beverage dispensers (1B) equipped with one
or two ice makers (1A) and a strip lid kit (2A and
2B) will need partial or total removal of items in
order to gain access to the ice storage bin for cooling coil heat exchanger installation (See Figures 1
and 2).If applicable on Servend 302 and 402 ice
beverage dispensers remove ice maker (1A), strip
lid panels (2A) and support brackets (2B) from the
left side of unit only to access the left side ice storage bin (See Figure 1). Keep all removed components and ice maker or makers in a safe place for
reinstallation later.
3. Remove all ice from the ice storage bin (3A) of dispenser in which the cooling coil heat exchange will
be installed (See Figure 2). On Servend 302 and
402 ice beverage dispensers remove ice from left
side ice storage bin only. Remove the paddlewheel
pin or pins (3B), agitator bar (3C), double –D coupling [where applicable], bin liner (3D) the four
knurled bin liner screws (3E), paddlewheel (3F),
paddlewheel area bushing [where applicable] and
paddle wheel area (3G) from ice storage bin (3A)
(See Figure 2). On Servend 302 and 402 ice beverage dispensers remove the components previously listed from the left side ice storage bin only.
Keep all removed components in a safe place for
reinstallation later.
4. Part of the rubberized bin gasket (4A) will need to
be trimmed away [3.00 inches] from the back left
side corner of the ice beverage dispenser (4B) as
shown (See Figure 3).
5. Use a 3.00 inch piece of the black adhesive foam
gasket included kit to seal for sanitation reasons
over the previously trimmed 3.00 inch area (4C).
Remove protective covering from black adhesive
foam gasket before adhering to surfaces of ice
beverage dispenser (See Figure 3).
6. Clean the left inside corner of ice storage bin (4D)

(7D) in the ice storage bin (7E) that components
were previously removed from (See Figure 5).
12. If applicable reinstall strip lid kit or components pre-
viously removed for access to install cooling coil
heat exchanger in the ice beverage dispenser. The
original left side strip lid panel (2A) and support
brace (2B) [where applicable] will be replaced by
a new lef
included with some but not all kits (See Figure 1).
13. Reinstall the ice maker or makers (1A) using the
proper install procedures on the ice beverage dispenser (1B) (See Figure 1).
14. Place label (8A) [Part No.5011948] near existing
serial tag (8B) of ice beverage dispenser (8C) (See
Figure 6).
15. Reconnect or turn on the water, power supplies to
the ice beverage dispenser and ice maker or makers. Check for leaks and make sure the ice bev-
erage dispenser, ice maker or makers operate
normally before placing units back into general
service.
