Installation Instructions
General System Overview
These instructions are provided to assist the qualified
installer. Contact your Manitowoc Beverage Equipment
Service Agent or call Manitowoc Beverage Equipment
for information regarding start-up services. CT Series
dispensers follow the same system layout but do not
have an ice bin.
Failure to follow these installation guidelines may
affect warranty coverage.
Typical Internal Carbonation Beverage Dispensing System
The carbonator in the post-mix system normally has two
inlet and one outlet connection. One inlet connects to
the CO
2 inlet. The other inlet connects the municipal
water supply. The outlet carries the carbonated water to
the cold plate inlets at the unit. The outlet of the syrup
supply connects to the appropriate coldplate syrup inlet
fitting. The syrup flows through the coldplate to be
chilled on its way to the valves. The water flows through
the coldplate chilling the plain and carbonated water on
its way to the valves. When both fluids leave the
beverage valve they are mixed in the nozzle of the valve.
Out comes a properly cooled, proper ratio soft drink.
Part Number 020005256 5/152-1
When starting a new beverage system of either type, be
sure the electrically operated valves are turned off.
Assure all connections are made, turn the water supply
on to the dispenser. Open CO
2 tank valve and set all
pressures. Place ice on the coldplate and allow the
coldplate to cool. After the beverage has achieved a
40°F temperature, the ratio of the product (brix) on a
post-mix system may then be set. (See Adjust Syrup to
Water Ratio (Brix) Page 2 - 21)

ELECTRICAL
General
Voltage
The standard voltage for CT, DI, & DIL dispensers is
All wiring must conform to local, state and national codes.
120VAC-60Hz 1 Ph. A power cord is provided with
120V AC-60Hz models only. 220/240 Volts - 50 Hz - 1 Ph,
208/230 Volts - 60 Hz - 1 Ph are also available.
Minimum Circuit Ampacity
Minimum Circuit Amperage Chart
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.
Electrical Requirements
Refer to Machine Model/Serial Plate for voltage/
amperage specifications.

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.
Risk of electrical shock. Connect to a properly grounded
outlet only.
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 th at
is properly installed and grounded in accordance with all
local codes and ordinances.
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 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.
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 equipmentgrounding 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. D o not
modify the plug provided with the appliance — if it will not
fit the outlet, have a proper outlet installed by a qualified
electrician.
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.

Unit Inspection
This section covers unpacking, inspecting, selecting location,
installing the unit, and preparing for operation. The Servend
Drop-In is shipped in a heavy duty corrugated car to n
with a wooden pallet. Inspect the Drop-In for freight
damage. If any damage is noticed, stop immediately and
contact your delivering freight company. You must file a
freight claim for your equipment. Failure to do so can
void any claims. Servend is not responsible for any
freight damage, thoroughly inspect the un it up on
delivery. Request a written inspection report from a
claims inspector to document any necessary claim.
1. After the unit has been unpacked, remove the keys.
The key will be needed to perform brixing of valves.
Hold onto the keys until such time to forward them to
the respective owner/operator. Remove tape (which
secures grid in place in drain pan) from grid and
other packing material.
2. Make sure all items are present and in good
condition. Loose shipped items in the carton include
the drain kit parts and the instructions.
Check Beverage Flavor Line-up
Double Check
Do you have enough space to install the
dispenser?
Is the countertop level?
Can the countertop support the weight of the
dispenser plus the weight of the stored ice?
Part Number 020005256 5/152-5
3. Inspect unit for any external damages.
If you have an internal carbonated unit the unit is preplumbed at the factory. The inlets for CO
2 and water are
located behind the splash panel. There are two inlets for
water and one inlet for CO
2. If you have questions refer
to the plumbing diagram on your equipment.

Incoming Water Supply Requirements
Manitowoc Beverage Equipment recommends that a
water shutoff valve and water filter be installed in the
incoming water supply line.
The incoming water source to the equipment shall be
installed with adequate backflow protection to comply
with applicable National, State, and local codes.
Water pressure should be a minimum of 45 psi or you
will starve the pump of water and damage it. The
maximum water pressure should be 55 psi or you will
affect the quality of the carbonation.
Step by Step Installation
To properly install the Servend Drop-In, Use these guidelines:
•Meet all local code requirements.
The unit must be sealed to the counter to comply with NSF
requirements.
•Have a receptacle with the proper voltage at the
installation site for connection to the Drop-In.
The carbonator pump should be located within 6 feet of
a 1/2 inch water source. A minimum 3/8 inch ID water
line must be used. Before connection the water source
should be flushed of approximately 5 gallons of water to
purge the system of any sediments, especially in areas
of new construction.
Location
Avoid placing the dispenser near heat sour ces such as
radiators, ovens, refrigeration equipment and direct sunlight.
Optimum Ambient Conditions are between 50°F and
95°F (10°C and 35°C).
•Completely unpack the Drop-In, removing all p adding
and shipping retainers.
•Route the beverage tubing from the syrup racks to
the location of the Drop-In.
•Make all beverage connections, if necessary, at the
syrup racks.
•Double check countertop cut out dimensions before
cutting countertop.
CARB/NON-CARB SETTINGS
Prior to placing the unit into the counter top it is recommended to make any carb/non-carb adjustments to the Flex
Manifold according to the provided beverage flavor line-up.
