TO THE INST
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

SAFETY INFORMATION
Recognize Safety Information
This is the safety-alert symbol. When you see this
symbol on our machine or in this manual, be alert to
the potentially of personal injury.
Follow recommended precautions and safe operating
practices.
Understand Signal Words
A signal word - DANGER, WARNING, OR CAUTION
is used with the safety-alert symbol. DANGER identifies the most serious hazards.
DANGER
Safety signs with signal word DANGER or WARNING
are typically near specific hazards.
General precautions are listed on CAUTION safety
signs. CAUTION also calls attention to safety messages in this manual.
WARNING
CAUTION
Follow Safety Instructions
Carefully read all safety messages in this manual and on your machine safety signs. Keep safety signs in
good condition. Replace missing or damaged safety signs. Learn how to operate the machine and how to
use the controls properly. Do not let anyone operate the machine without instructions. Keep your machine in
proper working condition. Unauthorized modifications to the machine may impair function and/or safety and
affect the machine life.
CO2(Carbon Dioxide) 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.
Shipping, Storing, Or Relocating Unit
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 temperature will cause residual water
remaining inside the Unit to freeze resulting in damage to internal components of the Unit.

GENERAL INFORMATION
TO THE USER OF THIS MANUAL
This is a Service and Maintenance Manual for the four and five-flavor Vantage Post-Mix Dispensers with integral
(built-in) cold carbonators (see figure 2 or 3) or the four and five-flavor Dispensers requiring connection to remote carbonators (see figures 4 or 5).These Dispensers will hereafter be referred to as Units. Retain this manual as part of your equipment.
This Unit must be installed and serviced by a qualified Service Person. This Unit contains no User serviceable
parts.
CLAIMS INSTRUCTIONS
Claims: In the event of shortage, notify the carrier as well as IMI Cornelius immediately. In the event of dam-
age, notify the carrier. IMI Cornelius is not responsible for damage occurring in transit, but will gladly
render assistance necessary to pursue your claim. Merchandise must be inspected for concealed damage within 15 days of receipt.

FIGURE 1. VANTAGE POST--MIX DISPENSER (FIVE-FLAVOR UNIT SHOWN)
THEORY OF OPERATION
UNIT WITH INTEGRAL (BUILT-IN) COLD CARBONATOR
(see applicable Figure 2 or 3)
A CO2supply delivers carbon dioxide (CO2) gas through adjustable CO2gas regulators to applicable syrup
tanks or bag-in-box syrup pumps and also to a built-in cold carbonator located inside the Unit. Plain water is
pumped into the 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 applicable syrup
tank or bag-in-box syrup pump pushes syrup from the syrup supply, through the Unit 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 valves. Syrup and carbonated
water meet simultaneously at the dispensing valve resulting in a carbonated drink being dispensed. On one
Unit, a non-carbonated (still) drink is dispensed from No. 5 Dispensing valve in the same manner as the carbonated drink except plain water is substituted for carbonated water.
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.

UNIT REQUIRING REMOTE CARBONATOR
(see applicable Figure 4 or 5)
A CO2supply delivers carbon dioxide (CO2) gas through adjustable CO2gas regulators to applicable syrup
tanks or bag-in-box syrup pumps and also to a remote carbonator that provides carbonated water to the Unit.
Plain water is pumped into the remote 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 applicable syrup tank or bag-in-box syrup pump pushes syrup from the syrup supply, through the
Unit cooling coils, and on to the dispensing valve. Carbonated water is pushed by CO
remote carbonator carbonated water tank and passes through the Unit carbonated water cooling coils and on to
the dispensing valves. Syrup and carbonated water meet simultaneously at the dispensing valve resulting in a
carbonated drink being dispensed.
The remote carbonator 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.
