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 As- sembly 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.
Request a written inspec- tion report from Claims Inspector to substantiate any necessary claim. File claim with the delivering carrier, not with IMI Cornelius Inc. After Cooling Unit has been unpacked, remove shipping tape and other packing material.
SELECTING LOCATION COOLING UNIT Select location for Cooling Unit installation that will (1) allow shortest possible insulated python run to dispensing station location; (2) allow shortest possible refrigeration lines (not to exceed 50-feet)) route from Remote Roof- top Condenser Coil and Fan Assembly to Cooling Unit; (3) The 60 Hz Cooling Unit is accessible to an electrical power circuit (voltage requirement is specified on the Unit nameplate).
PLACING COOLING UNIT IN LOCATION NOTE: An optional Cooling Unit Stand (P/N 309309069) is available to elevate Cooling Unit up and off the floor. 1. Place Cooling Unit in position approximately 36--inches out from operating position to allow access all around the Unit.
CONNECTING POTABLE WATER SOURCE SUPPLY LINES TO COOLING UNIT NOTE: IMI Cornelius Inc. recommends that a water shutoff valve be installed in the potable water source supply line connected to Cooling Unit (see FIGURE 2) and that water supply be filtered. WATER PIPE CONNECTIONS AND FIXTURES DIRECTLY CONNECTED TO A POTABLE WATER SUPPLY SHALL BE SIZED, INSTALLED AND MAINTAINED ACCORDING TO FEDERAL, STATE, AND LOCAL LAWS.
CAUTION: Potable water source supply line to be connected to the Cooling Unit water inlet lines 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, ‘...
CONNECTING COOLING UNIT CARBONATED WATER OUTLET LINES TO INSULATED PYTHON CARBONATED WATER LINES Using BARBED CONNECTORS (item 2) and TUBING CLAMPS (item 5), connect Cooling Unit 1/2--inch I.D. carbonated water outlet lines labeled “ CO WATER”to insulated python 1/2--inch I.D. carbonated water lines (see FIGURE 2).
1. Open the two service valves on the refrigeration system receiver tank fully to back--seat the valves (back-- seating the valves prevents leakage around the valve shafts). Replace caps on valves. 2. Make sure the plug in the end of the Cooling Unit water tank drain hose is secure. 3.
Standard Cooling Unit Utilizing Condenser Coil and Fan Assembly Place Cooling Unit REFRIGERATION POWER switch in ‘ ‘ ON’ ’position. Refrigeration compressor, condenser fan motor, and agitator motor will start and begin forming an ice bank and refrigerated Hydro Boostâ coil will also be chilling water.

OPERATORS INSTRUCTIONS This section covers operating controls, daily preoperation check, adjustments, replenishing CO and syrup sup- plies, cleaning and sanitizing, Cooling Unit maintenance, Remote Condenser Coil and Fan Assembly (if applica- ble) maintenance, lubrication, and servicing CO gas check valves. WARNING: Disconnect electrical power to Cooling Unit to prevent personal injury before attempting any Cooling Unit or Remote Condenser Coil and Fan Assembly (if applicable) internal maintenance.
COOLING UNIT CONNECTED TO REMOTE CONDENSER COIL AND FAN ASSEMBLY This Cooling Unit (see FIGURE 6) is equipped with a refrigeration system temperature sensing device and a high--pressure sensing cutout switch that will shut refrigeration system down should the system overheat due to a clogged condenser coil in Remote Condenser Coil and Fan Assembly.
CLEANING AND SANITIZING DAILY CLEANING Perform daily cleaning of dispensing station as instructed in dispensing station Installation Instructions. Outside of Cooling Unit must be cleaned periodically. SANITIZING SYRUP SYSTEMS Syrup systems should be sanitized every 90 days as instructed following Sanitizer Manufacturer’ s recommenda- tions.
REMOTE CONDENSER COIL AND FAN ASS’ Y (IF APPLICABLE) MAINTENANCE CAUTION: Remote Condenser Coil and Fan Assembly connected to the Cooling Unit (see FIGURE 6) is equipped with a condenser coil that must be cleaned every 30- -days. Allowing condenser coil to become clogged will cause Cooling Unit refrigeration system to overheat which will automatically shut refrigeration system down.
This section describes Service and Maintenance procedures to be performed on Cooling Unit and the Remote Condenser Coil and Fan Assembly. Note: The Aurora 10,000 Plus Cooling Unit (V2.5) is equipped with a built in system analyzer for diag- nostic troubleshooting of the Cooling Unit. Refer to TROUBLESHOOTING section of this manual for analyzer operating instructions.
COOLING UNIT MAINTENANCE CLEANING COOLING UNIT AIR INTAKE FILTERS CAUTION: Cooling Unit equipped with condenser coil (see FIGURE 5) is equipped with two air filters that must be cleaned every 30 days as instructed. Circulating air, required to cool the coil, is drawn in through air filters on back, and front of Unit and is exhausted out through coil on end of Unit.

5. Allow ice bank to melt. Hot water may be used to speed melting. 6. Thoroughly rinse inside of water tank with clean water. 7. Install plug in end of water tank drain hose. 8. Open shutoff valve in plain water inlet supply line. Due to slow water fill rate of water level float control, tank may be hand filled until water runs out of water tank overflow tube.
13. Service carbonator water pump outlet liquid double check valve as instructed in next paragraph. Servicing Carbonator Water Pump Outlet Liquid Double Check Valve 1. Service water strainer screen as instructed in previous paragraph before servicing carbonator water pump outlet liquid double check valve (see FIGURES 2 and 7). 2.

PRIMARY CO REGULATOR Adjust primary CO regulator on CO cylinder (see FIGURE 2) to a minimum nominal setting of 120--psi or 24--psi higher than highest setting required by the secondary CO regulators. Loosen CO regulator adjusting screw locknut. Turn adjusting screw to the right (clockwise) until regulator gage registers nominal 120--psi, then tighten adjusting screw locknut.
3. Wash cup rest, then rinse the cup rest with clean water. Install cup rest in the drip tray. 4. Clean all external surfaces of the Unit with a sponge. Rinse out the sponge with clean water, then wring excess water out of the sponge and wipe off all external surfaces on the Unit. Wipe Unit dry with a clean soft cloth.
