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.

BASIC FUNCTIONS
The FlexTower is a free standing unit which is designed for counter top merchandising and dispensing of non
carbonated finished beverages and flavoring syrups in any combination up to 16 flavors. Dispensing is accomplished by supplying syrup to an electric valve via a BIB pump and routing the syrup to a common dispense point
at an electric valve centrally located to supply plain water. Plain water for the non carbonated beverages is cooled
by circulation through a cooling coil placed in an adjacent ice dispenser bin and pumped by a circulation pump
located under the counter or by remote cooling units.
1. Pressing a labeled finished beverage selection
area on the touch pad activates the electric syrup
valve to deliver syrup and the water valve to provide water for the desired finished beverage.
2. Pressing a labeled flavor enhancer syrup only selection area on the touch pad activates the electric valve to provide the desired flavored syrup in
a predetermined quantity. Water is not dispensed
with flavor enhancer only flavored syrup.
3. The touchpads can be changed from a non carbonated finished beverage to flavor enhancer
syrup only through programming on the control
board. The FlexTower is shipped with the
touchpads programmed in the non carbonated
beverage mode by default.
4. 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.
5. A plain water supply capable of delivering 100 GPH
(378.5 liters/hr) with a minimum dynamic water
pressure of 40 PSI (2.75 BAR) and a maximum
static water pressure of 80 PSI (5.5 BAR) is required to provide water for the non carbonated
beverages. Water treatment is highly recommended to assure a quality finished beverage.
A drain pan connection is provided at the rear of the drain pan and must be routed to a drain in conformance with plumbing codes. (See Drainage Options)
The back room items (ordered separately) consist of:
1. Bag-in-box rack capable of holding sixteen flavor
boxes.
2. 0 – 100 PSI (0 – 6.9 BAR) Secondary regulator. For
non carbonated beverages delivery pressure is 40
PSI (2.75 BAR). For flavor syrup only, delivery pressure is 40 PSI (2.75 BAR).
3. Beverage pumps and connecting tubing.
4. Bag-in-box connectors as required by syrup
manufacturer.
5. Two (2) – eight (8) line, .250 (.635 cm) beverage
barrier tubing conduit – 100 ft. (30.5 meters).
6. Additional .250 (.635 cm) tubing for C02 supply.
7. Oetiker clamps and fittings.
8. 2.5 gallon (9.5 liter) bag-in-box syrup containers with
a dip tube to allow multidirectional placement on
the rack is suggested. This will allow for a 6-6-4
bag placement on the rack. This product is supplied by customer or syrup manufacturer and is not
available through Manitowoc Beverage Equipment.
