GENERAL DESCRIPTION
This section gives the description, theory of operation, and design data for the AuroraR10,000 Plus Cooling
Unit, hereafter referred too as a Cooling Unit.
COOLING UNIT DESCRIPTION
The Cooling Unit is designed to provide cooled syrup, carbonated water, and plain water to the dispensing
station through an insulated python (length as ordered). The Cooling Unit refrigeration system is cooled by a
Remote Condenser Coil and Fan Assembly which is connected to the Cooling Unit.
The Cooling Unit consists of a refrigeration system with a two horsepower compressor and a Hydro BoostR
(plain water pre-cooler) which pre-cools plain water on its way to the carbonated water tank. The Cooling Unit
also consists of a plain water pump. The plain water pump pumps plain water through the Hydro BoostR ,
through the plain water cooling coils, and into the carbonated water tank. The carbonated water circulating
pump circulates cold carbonated water from the Cooling Unit to the dispensing station and back to the Cooling
Unit.
The cabinet panels are easily removed to facilitate installation and service and maintenance.
An optional Cooling Unit Stand (P/N 309309000) is available to elevate Cooling Unit up off floor. Also available
is an Aurora Service System Analyzer (P/N 30919700) that may be used to analyze and troubleshoot the
Cooling Unit refrigeration system.
CAUTION: Before shipping or relocating the Cooling Unit syrup cooling coils must be
sanitized and all sanitizing solution must be purged from the coils. All water must also be
purged from the plain and carbonated water systems. A freezing ambient environment will
cause residual sanitizing solution or water remaining inside the Cooling Unit to freeze resulting in
damage to internal components.

SYSTEM THEORY OF OPERATION
(see Figure 2)
A CO2cylinder delivers carbon dioxide gas (CO2) to primary CO2regulator assembly which deliver regulated
CO2gas to adjustable secondary CO2regulators. Secondary CO2regulators delivers regulated CO2gas to the
carbonated water tank inside the Cooling Unit and also to the soft drink tanks. Plain water enters the Cooling
Unit and is pumped through and is pre-cooled by the refrigerated Hydro Boostâ coil. Cooled water continues
through the plain water cooling coils and into the carbonated water tank. Cold plain water entering the
carbonated water tank is carbonated by regulated CO2gas pressure also entering the tank. Carbonated water
leaves the carbonated water tank and enters the inlet side of the carbonated water circulating pump.
Carbonated water passes through the carbonated water circulating pump, through the carbonated water cooling
coil, and exits the Cooling Unit through an insulated python to a turnaround inside the dispensing station.
Carbonated water returns to the Cooling Unit by passing through the insulated python, through the Cooling Unit
carbonated water cooling coils, through the carbonated water tank which makes up the carbonated water
circulating system. As carbonated water is being dispensed from the dispensing station, carbonated water
circulating system is continuously being replenished from the carbonated water tank.
Plain water enters through the Cooling Unit two plain water inlet lines, through the plain water cooling coils, and
exists the Cooling Unit out through insulated python to the dispensing station. Regulated CO2gas pressure
exerted upon the soft drinks contents forces syrup from tanks, through Cooling Unit syrup inlet lines, through
syrup cooling coils, and exists the Cooling Unit out through an insulated python to the dispensing station.
The Cooling Unit refrigeration system is cooled by a Remote Condenser Coil and Fan Assembly (P/N
309602000) that is authorized by IMI Cornelius Inc. Use of any other Remote Condenser Coil and Fan
Assembly must be authorized by IMI Cornelius Inc. Use of an unauthorized Remote Condenser Coil and Fan
Assembly will automatically void the Cooling Unit factory warranty .

CONNECTING ELECTRICAL POWER CIRCUIT TO COOLING Unit
(see Figures 5 and 9)
IMPORTANT: Before 208/230VAC single-phase 60Hz electrical power circuit is connected to the cooling
unit, service power voltage entering the building must be identified. Service power voltage entering the
building will either be 208 or 230VAC and may be posted on the main service box. If not, the installer
must contact the local electrical power company for information. If these two voltage identification
attempts should fail, a voltage reading Must be performed. If service power voltage is below 218VAC,
the red electrical wire connected to the 240VAC terminal on LINE (primary) side of the 240/24VAC power
transformer inside the cooling unit switches electrical control box (see Figure 3 and 9) must be
disconnected from the 240VAC terminal and be connected to the 208VAC terminal. If voltage is above
218VAC, power transformer red electrical wire will remain connected to the 240VAC terminal. If installer
is not sure of the service power voltage entering the building, leave red electrical wire connected to the
240VAC terminal on the power transformer. If service power voltage is below 218VAC, proceed as
follows:
1. Remove four screws securing electrical control box cover, then remove cover for access to the
240/24VAC power transformer.
2. Remove red electrical wire from the 240VAC terminal on LINE (primary) side of power transformer
and connect it to the 208VAC terminal.

CONNECTING ELECTRICAL POWER CIRCUIT TO REMOTE CONDENSER COIL AND
FAN ASS’Y
(see Figure 5 and 9)
CAUTION: The Cooling Unit refrigeration system is cooled by a Remote Condenser Coil
and Fan Assembly (P/N 309602000) that is authorized by IMI Cornelius Inc. Use of an
unauthorized Remote Condenser Coil and Fan Assembly will automatically void the
Cooling Unit factory warranty.
NOTE: Electrical power circuit may be connected to the Remote Condenser Coil and Fan Assembly
(P/N 309602000) in two ways. The preferred way is to draw electrical power from the cooling unit
contactor which allows the Remote Condenser Coil and Fan Assembly to operate only when the
cooling unit refrigeration system is operating. The optional way is to connect a separate electrical
power circuit (independent of the cooling unit) through an appropriately rated and fused disconnect
switch or an equivalent HACR circuit breaker which allows the Remote Condenser Coil and Fan
Assembly to operate at all times (independent of cooling unit operation).
1. Connect and route electrical power circuit cable from Remote Condenser Coil and Fan Assembly through
fuse box (not provided), fused at 15-amps (maximum) down to Cooling Unit location. REMOTE
CONDENSER COIL AND FAN ASSEMBLY MUST BE PROPERLY GROUNDED, POWER CIRCUIT
MUST BE MADE UP OF COPPER CONDUCTORS, AND ALL WIRING MUST CONFORM TO NATIONAL
AND LOCAL ELECTRICAL CODES.
2. Route Remote Condenser Coil and Fan Assembly Power cable electrical wires through electrical handy
box on back of Cooling Unit to inside of electrical control box.

CONNECTING PLAIN WATER INLET SUPPLY LINE TO COOLING UNIT
(see Figure 2)
NOTE: IMI Cornelius Inc. recommends that a water shutoff valve be installed in plain water inlet supply
line connected to Cooling Unit and that water supply be filtered. WATER PIPE CONNECTIONS AND
FIXTURES DIRECTLY CONNECTED TO A POTABLE WA TER SUPPLY SHALL BE SIZED, INSTALLED
AND MAINTAINED ACCORDING TO FEDERAL, STA TE, AND LOCAL LAWS.
CAUTION: Plain water inlet supply line to Cooling Unit must be 1/2-inch I.D. minimum.
Check water flow rate of water inlet supply line. MINIMUM FLOW RATE MUST BE AT LEAST
300-GALLONS PER HOUR. If flow rate is less than 300-gallons per hour, ‘‘starving’’ of
carbonator water pump will occur. Starving will allow water pump to overheat causing safety
thermostat on pump outlet to disrupt electrical power to and stop water pump motor. Carbonated
water circulating pump overheating could occur if water inlet supply line flow rate drops below
300-gallons per hour. INCOMING PLAIN WATER INLET SUPPLY LINE WATER PRESSURE MUST
REMAIN A MINIMUM OF 10-PSI BELOW THE CARBONATOR CO2OPERA TING PRESSURE.
(Example: Operating pressure is 90-psi and maximum water pressure can be no more than 80-psi,
etc.)
1. Before connecting plain water inlet supply line to Cooling Unit, open water line shutoff valve for a period of
time to flush out any metal shavings and other contaminates that may have resulted from plumbing
connections.

WARNING: Disconnect electrical power to Cooling Unit and Remote Condenser Coil and
Fan Assembly to prevent personal injury before attempting any Cooling Unit or Remote
Condenser Coil and Fan Assembly internal maintenance. Only qualified personnel should
service internal components or electrical wiring.
CAUTION: to prevent Hydro-Boostâ coil freeze up during initial Cooling Unit start-up, the
following start-up procedure must be performed as follows:
1. Make sure Hydro Boostâ bypass shutoff valve inside Cooling Unit (see Figure 2) is in ‘‘CLOSED’’ (handle
not in line with tubing) position.
2. Make sure Cooling Unit REFRIGERATION POWER, CARBONATOR MOTOR, and CIRCULATING
MOTOR Power switches are in ‘‘OFF’’ positions.
3. Connect electrical power to Cooling Unit at disconnect switch. Connect electrical power to Remote
Condenser Coil and Fan Assembly at disconnect switch.
4. Place CARBONATOR MOTOR power switch in ‘‘ON’’ position.
5. Place REFRIGERATION power switch in ‘‘ON’’ position. Agitator motor and carbonator pump motor only
will start and fill Hydro-BoostR coil with plain water. APPROXIMATELY 2-1/2 MINUTES AFTER
CARBONATOR PUMP MOTOR HAS STARTED, REFRIGERATION COMPRESSOR, AND
COMPRESSOR COOLING FAN, WILL START.
NOTE: As ice bank forms in water tank, water expansion will take place and excess water will escape
through water tank overflow hose to permanent floor drain.
Cooling Unit will begin forming an ice bank and refrigerated Hydro-Boostâ coil will also be chilling water. When
full ice bank has been formed, Cooling Unit compressor and compressor cooling fan will stop but agitator motor
will continue to operate circulating ice water bath in water tank.
6. Dispense from dispensing station until carbonated water appears at dispensing valve which indicates
Cooling Unit plain and carbonated water systems have been filled.
7. Place CIRCULATING MOTOR power switch in ‘‘ON’’ position. Circulating pump will start and begin
circulating carbonated water in carbonated water circulating system as explained in SYSTEM THEORY OF
OPERATION in GENERAL INFORMATION SECTION.
8. Dispense carbonated water from dispensing valve to make sure all air has been purged from system.
9. If Cooling Unit plain water outlet line has been connected to a dispensing station dispensing valve,
dispense from valve until all air has been purged from plain water system.
10. Adjust soft drink tanks secondary CO2regulators (see Figure 2) as follows:Sugar
Syrup Soft Drink Tanks CO2Regulator.
Adjust sugar syrup soft drink tanks secondary CO2regulator at 40-psig for syrup lines up to 10-feet in
length plus one pound for each additional length of 10-feet, plus one pound for each 2-feet of vertical lift.
For example: if syrup line total length is 30-feet and total vertical lift is 6-feet, then 40-psig + 2-psig
(1-pound for every 10-feet of length over 10-feet which is 20-feet) + 3-psig (1-pound for every 2-feet of
vertical lift which is 6-feet); total equals 40 + 2 + 3 = 45-psig CO2regulator setting.
