SYSTEM THEORY OF OPERATION (see Figure 2) A CO cylinder delivers carbon dioxide gas (CO ) to primary CO regulator assembly which deliver regulated 2 2 2 CO gas to adjustable secondary CO regulators. Secondary CO regulators delivers regulated CO gas to the 2 2 2 2 carbonated water tank inside the Cooling Unit and also to the soft drink tanks. Plain water enters the Cooling Unit and is pumped through and is pre-cooled by the refrigerated Hydro Boostâ coil. Cooled water continues through the plain

CONNECTING ELECTRICAL POWER CIRCUIT TO COOLING Unit (see Figures 5 and 9) IMPORTANT: Before 208/230VAC single-phase 60Hz electrical power circuit is connected to the cooling unit, service power voltage entering the building must be identified. Service power voltage entering the building will either be 208 or 230VAC and may be posted on the main service box. If not, the installer must contact the local electrical power company for information. If these two voltage identification attempts should f

CONNECTING ELECTRICAL POWER CIRCUIT TO REMOTE CONDENSER COIL AND FAN ASS’ Y (see Figure 5 and 9) CAUTION: 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 an unauthorized Remote Condenser Coil and Fan Assembly will automatically void the Cooling Unit factory warranty. NOTE: Electrical power circuit may be connected to the Remote Condenser Coil and Fan Assembly (P/N 309602000) in two ways. T

Low-Calorie (diet) Syrup Soft Drink Tank CO Regulator. 2 Adjust low-calorie (diet) soft drink tank secondary CO regulator for low-calorie drink at 10-psig for 2 syrup lines up to 30-feet in length. Syrup lines longer than 30-feet in length may require a slightly higher CO regulator setting to 12-psig maximum. Excessive CO pressure may cause low-calorie syrup 2 2 carbonation resulting in foam. IMPORTANT: Syrup systems must be sanitized as instructed before syrup is connected into syrup systems. 1

REMOTE CONDENSER COIL AND FAN ASS’ Y MAINTENANCE (see Figure 5) CAUTION: Remote Condenser Coil and Fan Assembly connected to the Cooling Unit is equipped with a condenser coil that must be cleaned every 30-days. Allowing condenser coil to become clogged will cause refrigeration system to overheat which will automatically shut refrigeration system down. After condenser coil has been cleaned, high-pressure cutout sensing switch (see Figure 5) will have to be pressed to restart refrigeration system
