FIGURE 1. VA 13 CARBONATOR
UNIT DESCRIPTION
The carbonator is a compact Unit that may be installed in a remote location from where its carbonated water
outlet is to be connected to a post-mix dispenser or a system. The purpose of the Unit is to mix plain water and
carbon dioxide (CO2) gas which results in and provides carbonated water for a post-mix dispenser or a system.
The Unit consists basically of a water pump, motor, and a carbonated water tank. The water pump has a liquid
dual check valve (Unit Model No. 416411000, 496411000, 496411020, and 496411040) or a Vented Dual Check
Valve (Unit Model No. 1621) on its outlet to prevent carbonated water from back flowing into the city water system. The Vented Dual Check Valve vents water and possibly CO2 gas out of a vent port on failure of the primary
check valves. Should such venting occur, the primary check valve should be replaced. The Unit CO2 inlet has a
single check valve to prevent carbonated water back flow into the CO2 regulator.
318511001

Page 8
THEORY OF OPERATION
A CO2 cylinder delivers carbon dioxide (CO2) gas through an adjustable CO2 regulator to the carbonated water
tank. At the same time, plain water is pumped into the carbonated water tank by the water pump and is carbonated by CO
tank forces the tank and balance control mechanism down to activate the level control switches. Activating the
level control switches disrupts electrical power to and stops the water pump motor. As carbonated water is dispensed from the tank, the tank becomes lighter allowing the tank and balance control mechanism to rise which
again activates the level control switches. Activating the level control switches restores electrical power to the
water pump motor allowing the carbonated water tank to be replenished.
gas also entering the tank. Carbonated water enters the tank until the weight of the water in the

SELECTING LOCATION
Locate unit so following requirements are satisfied.
1. Locate the Unit in a cool area close to a properly grounded electrical outlet with proper electrical requirements fused at 15-amps (slow-blow). No other electrical appliance should be connected to this circuit. For
accessibility, the electrical outlet must not be located behind the Unit. ALL WIRING MUST CONFORM TO
NATIONAL AND ELECTRICAL CODES.
2. Locate the Unit close to a plain water source line with requirements as outlined in CAUTION note under
CONNECTING PLAIN WATER INLET LINE TO UNIT. Plain water inlet line from plain water source line to
the Unit should be 3/8-inch I.D. (minimum) food-grade plastic.
3. Locate the Unit close to a permanent drain if installing Unit (P/N 1621) which is equipped with a vented
Dual-Check Valve which must have it’s vent tube routed to a permanent drain.
INSTALLING THE UNIT
PLACING UNIT IN OPERATING LOCATION
7 318511001
Page 11
CAUTION: This Unit must not be installed in an unsheltered outdoor location where it will
be exposed to the elements.
IMPORTANT: Before putting carbonator into operation, carbonator cover must be removed and packing
block must be removed from below the water pump motor.
1. Place carbonator in operating location meeting requirements of SELECTING LOCATION. MAKE SURE
CARBONATOR IS SITTING IN LEVEL POSITION FOR PROPER OPERATION.
2. Remove two screws securing the cover assembly on the Unit, then remove the cover.
3. Remove packing block from below the water pump motor.
4. Install cover assembly on the Unit and secure with two screws.
5. Unit Model No. 1621.
IMPORTANT: A vented dual-check valve assembly is installed in this carbonator between the water
pump outlet and the water inlet to the carbonator tank as shown in Figure 3. The vented dual-check
valve assembly vents carbonated water, and possibly CO2 gas out of a vent port upon failure of the
primary check valves. Should such venting occur, the vented dual-check valve assembly must be
replaced.
CAUTION: Route free end of the vented dual–check valve vent tube to a permanent drain to
avoid serious water damage in the event of a check valve failure.
Route free end of the vented dual-check valve vent tube, protruding out the end of the carbonator cabinet, to a
permanent drain. TO AVOID POSSIBLE BACK-SUCTION FROM THE PERMANENT DRAIN, LOCATE THE
END OF THE VENTED DUAL-CHECK VALVE VENT TUBE ABOVE THE DRAIN OR AS REQUIRED BY THE
LOCAL PLUMBING CODE.
CONNECTING PLAIN WATER INLET SUPPLY LINE TO UNIT
CAUTION: Check minimum flow rate and maximum pressure of the 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 the carbonator water pump will occur. Starving
will allow the carbonator water pump to overheat causing the safety thermostat on the water pump
outlet to disrupt electrical power to and stop the water pump motor. Overheating could occur if the
plain water inlet supply line flow rate drops below 100-gallons per hour. WATER PRESSURE MUST
BE 10-PSI LESS THAN THE CO2 PRESSURE. (Example: operating CO2 pressure is 80-psi,
maximum water pressure can be no more than 70-psi, etc.). Water over pressure (higher than
operating pressure) can cause carbonator flooding, malfunction, and leakage through the
carbonator tank relief valve. If water is exceeding maximum pressure specifications, a Water
Pressure Regulator Kit (P/N 310150000) or equivalent must be installed in the plain water inlet
supply line. If fitting connector is not available, tap into the plain water supply line with a 3/8-flare
saddle valve (P/N 315664000) or equivalent.
NOTE: IMI Cornelius Inc. recommends that a water shutoff valve and water filter be installed in the
plain water inlet supply line (see Figure 2) . A Cornelius Water Filter (P/N 313860000) and Quick Disconnect Set (P/N 313867000) are recommended.
1. Make sure food grade flexible plastic 3/8-inch I.D. (minimum) plain water inlet line provides adequate water
flow rate and pressure as outlined in CAUTION note.
