THIS DOCUMENT CONTAINS IMPORTANT INFORMATION
This Manual must be read and understood before installing or operating this equipment
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 applicable syrup or product systems
must be sanitized and all sanitizing solution must be purged from the syrup or product 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 DESCRIPTION
This manual is a guide for installing, operating, and maintaining this equipment. Refer to Table of Contents for
page location of detailed information pertaining to questions that may arise during installation, operation, service
and maintenance, or troubleshooting this equipment.
This section gives the description, theory of operation, and design data for the Challenger I Pre-Mix Cooling Unit
with or without Seven-Flavor Bar Valve, the Challenger I Pre-Mix Cooling Unit with Five-Flavor Bar Valve, and
the Challenger I Post-Mix Seven-Flavor Cooling Unit.
UNIT DESCRIPTION
The Challenger I Cooling Units are equipped with a 1/5 H.P. refrigeration compressor.
PRE-MIX COOLING UNIT WITH FIVE-FLAVOR BAR VALVE
(See Figure 2)
The Cooling Unit is equipped with a five-flavor bar valve. The only requirements for operation are placing the
Cooling Unit in operating position, filling Cooling Unit water tank with water, connection of product tanks to the
Cooling Unit, and plugging the Cooling Unit power cord into an electrical outlet.
PRE-MIX COOLING UNIT WITH AND WITHOUT SEVEN-FLAVOR BAR VALVE
(see Figures 3 and 4)
This Cooling Unit may or may not be equipped with a seven-flavor bar valve. The Cooling Unit not equipped
with a seven-flavor bar valve requires connection of a dispensing station to the Unit. The only requirements for
operation are placing the Cooling Unit in operating position, connecting dispensing station to the Cooling Unit if
applicable, filling Cooling Unit water tank with water, connection of product tanks and a carbonated water tank to
the Cooling Unit, and plugging Cooling Unit power cord into an electrical outlet.
POST-MIX SEVEN FLAVOR COOLING UNIT
(see Figure 5)
This Cooling Unit requires connection to a dispensing station. The only requirements for operation are placing
the Cooling Unit in operating position, connection of dispensing station to the Cooling Unit, connection of syrup,
plain water, and carbonated water sources to the Cooling Unit, and plugging Cooling Unit power cord into an
electrical outlet.

THEORY OF OPERATION
PRE-- MIX SYSTEM WITH FIVE--FLAVOR BAR VALVE
(see Figure 2)
A CO2cylinder delivers carbon dioxide (CO2) gas through adjustable CO2regulators to the product tanks. When
valve on the bar valve is opened, CO2pressure exerted upon the product tank pushes product from the tank,
through the Cooling Unit cooling coil, and on to the bar valve resulting in a dispensed drink.
PRE-- MIX SYSTEM WITH SEVEN--FLAVOR BAR VALVE
(see Figure 3)
A CO2cylinder delivers carbon dioxide (CO2) gas through adjustable CO2regulators to the product tanks and to
the carbonated water tank. When applicable valve (pre-mix drink or carbonated water) on the bar valve is
opened, CO2pressure exerted upon the product tank or the carbonated water tank pushes product or
carbonated water from the tank, through the Cooling Unit cooling coil, and on to the bar valve resulting in either
product or carbonated water being dispensed. Opening the plain water valve on the bar valve allows plain water
to pass through the Cooling Unit cooling coil and on to the bar valve resulting in cold plain water being
dispensed.
PRE-- MIX SEVEN--FLAVOR SYSTEM WITHOUT BAR VALVE
(see Figure 4)
A CO2cylinder delivers carbon dioxide (CO2) gas through adjustable CO2regulators to the product tanks and to
the carbonated water tank. When applicable dispensing valve (pre-mix drink or carbonated water) on the
dispensing station is opened, CO2pressure exerted upon the product tank or the carbonated water tank pushes
product or carbonated water from the tank, through the Cooling Unit cooling coil, and on to the dispensing
station resulting in either product or carbonated water being dispensed. Opening the dispensing station plain
water dispensing valve allows plain water to pass through the Cooling Unit cooling coil and on to the dispensing
station resulting in cold plain water being dispensed.
POST --MIX SEVEN--FLAVOR SYSTEM
(see Figure 5)
A CO2cylinder delivers carbon dioxide (CO2) gas through adjustable CO2regulators to applicable syrup tanks
or bag-in-box syrup pumps and also to the remote carbonator. Plain water entering the remote carbonator water
tank is carbonated by regulated CO2gas also entering the tank. When the dispensing station dispensing valve
is opened, CO2pressure exerted upon the applicable syrup tank or bag-in-box syrup pump pushes syrup from
the syrup supply, through the Cooling Unit cooling coil, and on to the dispensing station. Carbonated water is
pushed from the carbonator water tank by CO2gas head pressure through the Cooling Unit cooling coil and on
to the dispensing station. Syrup and carbonated water meet simultaneously at the dispensing valve resulting in
a carbonated drink being dispensed. Opening the dispensing station plain water dispensing valve allows plain
water to pass through the Cooling Unit cooling coil and on to the dispensing station resulting in cold plain water
being dispensed.
