INSTALLATION
INTRODUCTION
This manual is intended to assist the installer and
service personnel in the installation instructions,
operation, and maintenance procedures to be
performed on the Aurora Beverage Dispensing
System.
NOTE: These pieces of equipment are made in
America and have American sizes on the
hardware All metric conversions are approximate
and vary in size.
BEVERAGE CONTROL ST AND ASSEMBLY
The Beverage Control Stand Assembly is designed
to filter, pressure regulate, and distribute plain water,
CO2and syrup through the Aurora Beverage
Dispensing System. (see applicable Figure 1 or 2 ).
AURORA COOLING UNIT
NOTE: Refer to Installation manual provided with
your Cooling Unit for specifications, installation
instructions, service and maintenance, and
troubleshooting.
The Aurora Beverage Dispensing System uses one
of several differently configured Aurora Cooling Units
described as follows:
Standard Aurora Cooling Unit (P\N 0833, 50 HZ) and
(P/N 0832, 60 HZ).
The Standard Aurora Cooling Unit refrigeration
system is cooled by a condenser coil and fan
assembly located inside the Cooling Unit.
Aurora Cooling Unit (P/N 0740, 50 Hz) and (P/N
0851, 60 Hz) Requiring Connection to a Remote
Condenser Coil and Fan Assembly
The Aurora Cooling Unit refrigeration system is
connected to and is cooled by a Remote Condenser
Coil and Fan Assembly .
Water Cooled Aurora Cooling Unit (P/N 1415, 50HZ)
and (P/N 1414, 60 HZ) Requiring Connection to a
Plain Water Inlet Supply Line
The Water Cooled Aurora Cooling Unit refrigeration
system is cooled by cold water connected to the
Cooling Unit which circulates through a plain
water/freon cooling coil located inside the Cooling
Unit.
POST- MIX BEVERAGE DISPENSING TOWER
NOTE: Refer to Installation Manual provided with
your Post-Mix Beverage Dispensing Tower for
specifications, installation instructions, service
and maintenance, and troubleshooting.
The Post-Mix Beverage Dispensing Tower is
designed to dispense carbonated and
non-carbonated (still) drinks and only carbonated or
plain water if desired. The dispensing valves are
equipped with portion control capability which may be
programmed to dispense a small, medium, large, or
an extra large drink. Syrup, carbonated water, and
plain water are cooled by the Aurora 10,000 Plus
Cooling Unit. Cold carbonated water, cooled by the
Cooling Unit, is circulated through the insulated
python connected between the Cooling Unit and the
Post-Mix Beverage Dispensing Tower which keeps
the syrup and plain water lines inside the python
cold.
INSTALLING AURORA BEVERAGE
DISPENSING SYSTEM
PLACING BEVERAGE CONTROL ST AND
ASSEMBLY IN OPERATING POSITION
NOTE: The Beverage Control Stand Assembly
must be placed in operating position with
18-inches on sides and back and front (CO
regulator panel assembly side) side must be
open to the room and top open to the ceiling.
The Stand Assembly must be close to a plain
water source supply line with proper
requirements as specified in SPECIFICATIONS. If
either or both the Air Compressor Kit or the
Water Pressure Booster Kit are used, a properly
grounded electrical outlet with proper electrical
circuit requirements must be avbailable. The
electrical circuit must be fused at 15-amps
(‘‘slow-blow’’) or circuit must be connected
through an equivalent HACR circuit breaker. No
other electrical equipment should be connected
to this circuit. ALL ELECTRICAL WIRING MUST
CONFORM TO NA TIONAL AND LOCAL
ELECTRICAL CODES.
Placing Beverage Control Stand Assembly in
operating position meeting requirements specified in
preceding NOTE. MAKE SURE BEVERAGE
CONTROL STAND ASSEMBLY IS SITTING LEVEL
BY ADJUSTING FOUR ADJUSTABLE LEVELING
LEGS.

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.
