GENERAL INFORMATION
IMPORTANT: To the user of this manual - This manual is a guide for installing, operating, and maintaining this equipment. Refer to the Table of Contents for page location for detailed information pertaining to questions that arise during installation, operation, service, or maintenance of this
equipment.
GENERAL DESCRIPTION
This section gives the Unit description, theory of operation, and design data for the five and six-flavor Ventures
Post-Mix Dispensers with Built-In Cold Carbonators (hereafter referred to as Units).
This Unit must be installed and serviced by a qualified Service Person. This Unit contains no User serviceable
parts.
UNIT DESCRIPTION
The Units are compact with high-impact and corrosion-resistant moulded lower housings and may be islandmounted or installed on a front or rear counter. Their refrigeration assemblies are the 1/3 H.P. drop-in type that
can be easily removed for service and maintenance. The Units are equipped with built-in cold carbonators with
their carbonated water tanks located inside the Units lower housings water tanks. Adjustable syrup flow
regulators, located on the electrically operated dispensing valves, are easily accessible to control water-to-syrup
“Ratio” of the dispensed product.
Installation of the Unit on a countertop, installation of LOOSE-SHIPPED PAR TS, connection of plain water and
syrup supplies, adjustment of CO2regulators, filling water tank with water, and plugging the Unit power cord into
an electrical outlet is all that is required for operation.
NOTE: Optional 4-inch Legs (P/N 314744000) that will elevate the Unit 4-inches above the countertop
are available. When ordering legs, order a quantity of four.
CAUTION: Before shipping, storing, or relocating this Unit, the syrup systems must be
sanitized and all sanitizing solution must be purged from the syrup systems. All water must
also be purged from the plain and carbonated water systems. A freezing ambient
environment will cause residual water in the Unit to freeze resulting in damage to internal
components.

THEORY OF OPERATION
(see applicable Figure 2 or 3)
WARNING: CO2displaces oxygen. Strict attention must be observed in the prevention of
CO2(carbon dioxide) gas leaks in the entire CO2and soft drink system. If a CO2gas leak is
suspected, particularly in a small area, immediately ventilate the contaminated area before
attempting to repair the leak. Personnel exposed to high concentration of CO2gas will experience
tremors which are followed rapidly by loss of consciousness and suffocation.
NOTE: The six-flavor (see Figure 3) Unit was set up at the factory to dispense a still (noncarbonated)
drink from No. 3 dispensing valve and carbonated drinks from the remaining dispensing valves.
A CO2cylinder delivers carbon dioxide (CO2) gas through adjustable CO2regulators to applicable syrup tanks
or bag-in-box syrup system syrup pumps and to a built-in carbonator located inside the Unit. Plain water is
pumped into the carbonator carbonated water tank by a water pump and is carbonated by regulated CO2gas
pressure also entering the tank. When a dispensing valve is opened, CO2gas pressure exerted upon the syrup
tank or on the bag-in-box system syrup pump, pushes syrup through the Unit syrup cooling coils, and on to the
dispensing valve. Carbonated water is pushed by CO
passes through the Unit carbonated water cooling coils, and on to the dispensing valve.
Syrup and carbonated water meet simultaneously at the dispensing valve resulting in a carbonated drink being
dispensed. On the six-flavor Unit, a still (noncarbonated) drink is dispensed from the No. 3 dispensing valve in
the same manner as the carbonated drink except plain water is substituted for carbonated water.
gas pressure from the carbonated water tank and
2
The carbonated water tank is replenished when the carbonated water level inside the tank drops, which in turn
automatically starts the carbonator water pump. When the carbonated water level inside the tank has been replenished, the carbonated water pump will stop.

SELECTING LOCATION
CAUTION: This Unit is intended for indoor installation only. Do not install this Unit in an
outdoor environment which would expose it to the outside elements.
This Unit may be island-mounted or installed on a front or rear counter. Locate the Unit so the following
requirements are satisfied:
DANGER: To avoid possible fatal electrical shock or serious injury to the operator, it
is required that a GFCI (ground fault circuit interrupt) be installed in the electrical circuit
for the domestic Units. It is required that an ELCB (earth leakage circuit breaker) be
installed in the electrical circuit for the export Units
1. The Unit must be installed near a properly grounded electrical outlet with proper electrical requirements.The electrical circuit must be properly fused (slow-blow type fuse) or the circuit must be connected
through an equivalent HACR circuit breaker.The electrical outlet must be accessible for ease of connecting
and disconnecting the Unit power cord. No other electrical equipment should be connected to this circuit.
REFER TO UNIT NAMEPLATE FOR THE REQUIRED POWER CIRCUIT OPERATING VOLTAGE, HZ,
AND THE MINIMUM CIRCUIT AMPACITY OF THE UNIT. ALL ELECTRICAL WIRING MUST CONFORM
TO NATIONAL AND LOCAL ELECTRICAL CODES.
CAUTION: Do not place or store anything on top of the Unit.
2. A minimum of 15-inches clearance must be maintained above the Unit to the nearest obstruction (shelf,
cupboard, ceiling, etc.) and 6-inches clearance between back-side of the Unit and the wall. The front grille
of the Unit must be unobstructed to allow air to enter the hood.
3. Close to a permanent drain to route drip tray drain hose and water tank drain hose.
INSTALLING WATER ONLY LEVER KIT (P/N 3297) ON UF-1 DISPENSING
VAL VE
The WATER ONLY LEVER KIT, UF-1 DISPENSING VALVE (item 10) is loose-shipped with all six-flavor
Dispensers equipped with UF-1 dispensing valves. Installation of this kit on the dispensing valve allows plain or
carbonated (depending on which dispensing valve the kit has been installed on) water only to be dispensed. If
desired, the kit may be installed at this time following instructions included with the kit.
INSTALLING UNIT
NOTE: Optional 4-inch Legs (P/N 314744000) that will elevate the Unit 4-inches above the countertop
are available. When ordering legs, order a quantity of four.
CUTTING HOLE IN COUNTERTOP
Place Unit in location on the countertop flush with the countertop edge. Mark Unit center line on edge of the
countertop, then move Unit off to one side. Starting at center line mark on edge of the countertop, measure
back 8-inches for location of the 2-1/2-inch diameter hole to be cut in the countertop. Cut a 2-1/2-inch hole in
the countertop where indicated. Place the Unit in position over the hole.
CONNECTING PLAIN W ATER SOURCE LINE(S) TO UNIT
(see applicable Figure 2 or 3 and Figure 4)
NOTE: IMI Cornelius Inc. recommends that a water shutoff valve and water filter be installed in the
plain water inlet supply line (see applicable Figure 2 or 3) . A Cornelius Water Filter (P/N 313860000)
and Quick Disconnect Set (P/N 313867000) are recommended.

IMPORTANT: TO THE INSTALLER. It is the responsibility of the Installer to ensure that the water supply
to the dispensing equipment is provided with protection against backflow by an air gap as defined in
ANSI/ASME A112. 1.2-1979; or an approved vacuum breaker or other such method as proved effective
by test.
Water pipe connections and fixtures directly connected to a potable water supply shall be sized,
installed, and maintained according to Federal, State, and Local laws.
CAUTION: Check the minimum flow rate and maximum pressure of plain water inlet supply
line. MINIMUM FLOW RA TE MUST BE AT LEAST 100-GALLONS PER HOUR. If flow rate is
less than 100-gallons per hour, starving of carbonator water pump will occur. Starving will
allow water pump to overheat and will damage the pump. Overheating could occur if plain water
inlet supply line flow rate drops below 100-gallons per hour. CARBONATOR CO2OPERA TING
PRESSURE MUST EXCEED WATER PRESSURE BY 10 PSI. (Example: CO2operating pressure is 80
psi, maximum water pressure can be no more than 70 psi, etc.) Water over pressure (higher than
CO2operating pressure) can cause carbonator flooding, malfunction, and leakage through
carbonator relief valve. If water is exceeding maximum pressure specifications, a Water Pressure
Regulator Kit (P/N 317589000) or equivalent must be installed in plain water inlet supply line.
Five and Six-Flavor Units (see applicable Figure 2 or 3)
1. Route plain water source line from plain water source up to location under the countertop.
2. Remove Unit front access panel as follows:
A. Remove drip tray from the Unit.
B. Remove two screws securing front access panel to the Unit.
C. Pull front access panel down and out to remove for access to front of the Unit.
3. Route plain water source line up through hole cut in the countertop, up across front of the Unit, to the carbonator water pump.
4. Install FITTING, 90° SWIVEL ELBOW (item 9) on end of the plain water source line and secure with
TUBING CLAMP (item 8).
5. Connect plain water source line 90° elbow to the carbonator water pump inlet fitting. Seal connection with
TAPERED GASKET, BLACK (item 7).
Six-Flavor Units (see Figure 3)
NOTE: The six-flavor (see Figure 3) Unit was set up at the factory to dispense a still (noncarbonated)
drink from No. 3 dispensing valve and carbonated drinks from the remaining dispensing valves.
1. Route plain water source line up to back side of the Unit.
2. Connect plain water source line to the Unit labeled plain water inlet line protruding out back of the Unit with
ADAPTOR FITTING (item 4). This water line provides plain water to the Unit No. 3 dispensing valve which
dispenses a still (non-carbonated) drink.
CONNECTING SYRUP SOURCE LINES TO UNIT
(see applicable Figure 2 or 3 and Figure 4)
NOTE: The Unit syrup inlet lines are labeled to identify the dispensing valves they serve. For example,
the line labeled “S1” must be connected to the syrup source line that provides syrup to be dispensed
from the No. 1 dispensing valve (No. 1 dispensing valve is the valve on the right side when facing front
of the Unit).
