GENERAL INFORMATION

IMPORTANT: To the user of this manual - 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 arise during installation, operation, service and maintenance, or trouble-shooting this equipment.

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 shipping or relocating Cooling Unit, syrup cooling coils must be sanitized and all sanitizing solution must be purged from coils. All water must also be

purged from plain and carbonated water systems. A freezing ambient environment will cause residual sanitizing solution or water remaining inside 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 delivers regulated CO2gas to adjustable secondary CO2regulators. Secondary CO2regulators deliver regulated CO2gas 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 CO2gas 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 CO2gas 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.

COMPRESSOR DOES NOT OPERATE (CONT’D)

I. Hi-pressure cutout tripped

(remote Cooling Unit only).

J. No voltage to control board. J. Check for loose or broken wiring.

K. Inoperative compressor. K. Replace compressor. L. Temperature sensor is shorted

or open circuit.

M. Loose or broken wire to

satellite board from ice sensor probe on main control board (see low-voltage system wiring diagram).

I. Reset pressure switch (see

REFRIGERATION SYSTEM TEMPERATURE SENSING DEVICE AND HIGH-PRESSURE CUTOUT SWITCH in OPERATORS INSTRUCTIONS SECTION.

Check 240/24 VAC power transformer for 24 VAC output. (see NOTE below)

L. Check for loose, broken, or

disconnected wire or plug at pre-cool coil. Repair or replace wire. Confirm which temperature sensor has failed by using the Aurora Series System Analyzer (P/N 309197-000).

M. Repair or replace wire.

NOTE: The 240/24 VAC power transformer has an overload reset button located on its 24 VAC output side (see Figure 3). An overload on the transformer will cause its reset button to pop out disrupting the 24 VAC output to the main control board. Overload reset button must be pressed in to restore 24 VAC output.

E. Inoperative or disconnected

pulse-modulating expansion

valve (see applicable

REFRIGERATION FLOW

DIAGRAM).

E. Check that expansion valve is

operating by touch (should be able to feel valve pulse).Check for loose or disconnected wire to solenoid coil. If necessary, troubleshoot expansion valve with a gage set to see if it is opening. If expansion valve is not opening, suction pressure will be in a vacuum.

F. Inoperative control board. No

output from board to

solenoids.

F. Check LED’s on control board to

see if they are modulating. Check for 24V output to pulse modulating expansion valve (see WIRING DIAGRAM). If control board green LED is on and yellow LED Is flashing; but no 24V output, replace board.

NOTE: If overload protector cuts out compressor, condenser fan motor will continue to operate otherwise; troubleshooting condenser fan motor problem is same as for ‘‘COMPRESSOR DOES NOT OPERA TE’’ paragraph plus the following:
