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.
