2. The beverage tubes, drain tube and power cord are routed through the large opening in the bottom of the unit.
See the MOUNTING TEMPLATE for locating the required clearance opening in the counter for these utility
lines.
DRIP TRAY DRAIN ASSEMBLY: Route the drain tube to an open drain with the end of the tube above the flood
level of the drain. Use the tubing, fittings, clamps, and insulation provided with the Dispenser to assemble the drain.

NOTE: Cornelius Inc. recommends that a water shutoff valve and water filter be installed in the
plain water inlet supply line. A Cornelius Water Filter (P/N 313860000) and QUICK DISCONNECT
SET (P/N 313867000) are recommended.

CAUTION:
Check the minimum flow rate and the maximum pressure of the plain water inlet supply line. MINIMUM FLOW RATE
MUST BE AT LEAST 125 GALLONS PER HOUR. If flow rate is less than 125 gallons per hour, starving of the
carbonator water pump will occur. Starving will overheat the carbonator s water pump, causing the safety thermostat
on the pump outlet to stop the water pump motor. Overheating could occur if the plain water supply line flow rate
drops below 125 gallons per hour. INCOMING PLAIN WATER INLET SUPPLY LINE WATER TO PUMP PRESSURE
MUST REMAIN A MINIMUM OF 10 psi BELOW THE CARBONATED CO
Carbonator CO operating pressure is 75 psi and the maximum water pressure can be no more than 65 psi, etc.).

Static water pressure higher then the static CO
through the carbonator relief valve. If water is exceeding maximum pressure specifications, a Water Pressure
Regulator Kit must be installed in the plain water inlet supply line.
3. Cut power to the carbonator by turning off its power switch, the switch is located on the junction box of the
pump and motor assembly. Locate the carbonator pump assembly and connect to power cord from the Ice/
Drink Unit to the pump. The cord is connected to the unit s electrical box and has an electrical connector on the
end that plugs into a receptacle in the junction box at the carbonator pump assembly. Connect inlet water to
pump and pump outlet to Ice/Drink Unit using 3/8-inch food-grade tubing.
