Cornelius R-134A service manual Connecting Syrup Source Lines to Unit

IMPORTANT: TO THE INSTALLER. It is the responsibility of the Installer to ensure that the water supply to the dispensing equipment is provided with protection against backflow by an air gap as defined in ANSI/ASME A112. 1.2-1979; or an approved vacuum breaker or other such method as proved effective by test.

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: Check the minimum flow rate and maximum pressure of plain water inlet supply line. MINIMUM FLOW RATE MUST BE AT LEAST 100-GALLONS PER HOUR. If flow rate is less than 100-gallons per hour, starving of carbonator water pump will occur. Starving will

allow water pump to overheat and will damage the pump. Overheating could occur if plain water inlet supply line flow rate drops below 100-gallons per hour. CARBONATOR CO2 OPERATING PRESSURE MUST EXCEED WATER PRESSURE BY 10 PSI. (Example: CO2 operating pressure is 80 psi, maximum water pressure can be no more than 70 psi, etc.) Water over pressure (higher than CO2 operating pressure) can cause carbonator flooding, malfunction, and leakage through carbonator relief valve. If water is exceeding maximum pressure specifications, a Water Pressure Regulator Kit (P/N 317589000) or equivalent must be installed in plain water inlet supply line.

Five and Six-Flavor Units (see applicable Figure 2 or 3)

1.Route plain water source line from plain water source up to location under the countertop.

2.Remove Unit front access panel as follows:

A.Remove drip tray from the Unit.

B.Remove two screws securing front access panel to the Unit.

C.Pull front access panel down and out to remove for access to front of the Unit.

3.Route plain water source line up through hole cut in the countertop, up across front of the Unit, to the car- bonator water pump.

4.Install FITTING, 90°SWIVEL ELBOW (item 9) on end of the plain water source line and secure with TUBING CLAMP (item 8).

5.Connect plain water source line 90°elbow to the carbonator water pump inlet fitting. Seal connection with TAPERED GASKET, BLACK (item 7).

Six-Flavor Units (see Figure 3)

NOTE: The six-flavor (see Figure 3) Unit was set up at the factory to dispense a still (noncarbonated) drink from No. 3 dispensing valve and carbonated drinks from the remaining dispensing valves.

1.Route plain water source line up to back side of the Unit.

2.Connect plain water source line to the Unit labeled plain water inlet line protruding out back of the Unit with ADAPTOR FITTING (item 4). This water line provides plain water to the Unit No. 3 dispensing valve which dispenses a still (non-carbonated) drink.

CONNECTING SYRUP SOURCE LINES TO UNIT

(see applicable Figure 2 or 3 and Figure 4)

NOTE: The Unit syrup inlet lines are labeled to identify the dispensing valves they serve. For example, the line labeled “S1” must be connected to the syrup source line that provides syrup to be dispensed from the No. 1 dispensing valve (No. 1 dispensing valve is the valve on the right side when facing front of the Unit).
