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 car-
bonator water pump can occur. Starving causes the carbonator water pump to overheat, causing the safety thermo-
stat on the pump outlet to stop the water pump motor.
CAUTION:
!
I
NCOMING PLAIN WATER INLET SUPPLY LINE WATER TO PUMP PRESSURE MUST REMAIN A MINIMUM OF
10 psi BELOW THE CARBONATED CO2 OPERATING PRESSURE
. (Example: Carbonator CO
2
operating pres-
sure is 75 psi and the maximum water pressure can be no more than 65 psi, etc.). Water over pressure (higher than
CO
2
operating pressure) can cause carbonator flooding, malfunction, and leakage 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. If a fitting connector is not available, tap into the plain water supply line with a 3/8 flare saddle
valve.
