GENERAL DESCRIPTION  
This section gives the description, theory of operation, and design data for the AuroraR10,000 Cooling Unit,  
(hereafter referred to as a ‘‘Cooling Unit’’).  
COOLING UNIT DESCRIPTION  
The Cooling Unit is designed to provide cooled soft drink syrup, carbonated water, and plain water to dispensing  
station through an insulated python (length as ordered). On the standard Cooling Unit, refrigeration system is  
cooled by condenser coil and fan assembly located inside the Cooling Unit. Cooling Unit not provided with  
internal condenser coil and fan assembly is cooled by Remote Condenser Coil and Fan Assembly which is  
connected to Cooling Unit. The Cooling Unit consists basically of two carbonator tanks each having its own  
water pump to pump plain water into tanks, one carbonated water circulating pump, a Hydro Boostâ  
(carbonated water pre-cooler) which pre-cools carbonated water on its way to carbonated water circulating  
pump and a two horsepower refrigeration compressor. 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. A System  
Status Display Kit (P/N 0913) is available and when installed on the Cooling Unit, allows operator or technician  
to monitor operation of Cooling Unit and to be aware when service is required. Also available is an Aurora  
Service System Analyzer (P/N 309197000) that may be used to analyze and troubleshoot the Aurora 10,000  
Cooling Unit refrigeration system.  
CAUTION: Before s hipping or relocating Cooling Unit, s yrup cooling coils mus t be  
s anitized and all s anitizing s olution mus t be purged from coils . All water mus t als o be  
purged from plain and carbonated water s ys tems . A freezing ambient environment will  
caus e res idual s anitizing s olution or water remaining ins ide Cooling Unit to freeze res ulting in  
damage to internal components .

SYSTEM THEORY OF OPERATION  
(see Figure 2)  
A CO2 cylinder delivers carbon dioxide gas (CO2) to primary CO2 regulator assembly which delivers regulated  
CO2 gas to adjustable secondary CO2 regulators. Secondary CO2 regulators deliver regulated CO2 gas to both  
carbonated water tanks inside Cooling Unit and also to soft drink tanks. Plain water is pumped into carbonated  
water tanks by water pumps and is carbonated by regulated CO2 gas pressure also entering tanks. Carbonated  
water leaves carbonated water tanks and passes through the Hydro BoostR(carbonated water pre-cooler)  
which pre-cools carbonated water on its way to carbonated water circulating pump. Pre-cooled carbonated  
water enters carbonated water circulating system through inlet side of carbonated water circulating pump.  
Carbonated water passes from outlet side of carbonated water circulating pump, through cooling coils inside  
water tank, and out through insulated line to turnaround inside dispensing station. Carbonated water returns to  
Cooling Unit by passing through insulated line, through cooling coils, and on to carbonated water circulating  
pump inlet which makes up the carbonated water circulating system. As carbonated water is being dispensed  
from dispensing station, carbonated water circulating system is continuously being replenished from both  
carbonated water tanks. Regulated CO2 gas pressure, exerted upon soft drink tanks contents, forces syrup  
from tanks, through Cooling Unit cooling coils, and on to dispensing station through insulated lines.  
Standard Cooling Unit.  
The standard Cooling Unit refrigeration system is cooled by a condenser coil and fan assembly located inside  
Cooling Unit.  
Cooling Unit Requiring Connection to Remote Condenser Coil and Fan Assembly.  
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.

balance. Check and make sure wire guard is properly installed and securely fastened.  
4. Check and make sure roof area immediately surrounding unit is free and clear of any debris that may have  
collected such as leaves, paper, trash, etc.  
5. Restore electrical power to Cooling Unit at disconnect switch.  
CHECKING ICE WATER BATH  
(see applicable Figure 5 or 6)  
A gurgle heard from Cooling Unit indicates water level in water tank is low. This indicates the water tank water  
level float control is not operating properly and must be repaired or replaced. If a continuous trickle of water is  
coming out of the water tank overflow tube, this indicates the water level float control is not shutting off properly  
and must be repaired or replaced. Ice water bath and ice bank should be checked for cleanliness and water  
tank coils and the water level float control should be checked for excessive mineral deposit build-up as follows:
