Section 3 Operation
CARBONATION
The purpose of the carbonator is to take regular tap water
at street water pressure (minimum 20 psi, maximum 80 psi,
dynamic or flowing pressure) 1/2" water line and increase
the water to beverage system pressure (usually 100 psi).
This water is then combined with the CO
2
gas. Because the
water and gas are at the same pressure, the CO
2
will dissolve
into the water. Chilling the mixture before dispensing will
assist in locking the carbon dioxide into the water. After
dispensing, the CO
2
may be unlocked from the liquid. The
CO
2
will gradually leave the liquid due to pressure and
temperature changes.
Components
The components of the carbonator are: water pump, an
electric motor to operate the pump, carbonator tank where
the water and CO
2
mix, and a water level control.
Operation
Carbon Dioxide (CO
2
) leaves the storage tank and arrives
at the carbonator tank through the gas inlet. Water supply
enters the carbonator pump inlet at regular street water
line pressure (minimum 20 psi, maximum 80 psi, dynamic or
flowing pressure). The water pump increases the pressure
of the water, which allows the water to flow into the
carbonator tank. The CO
2
and the water mix together in the
carbonator to produce the carbonated water that is then
sent to the soda dispenser.
The agitation of the water and CO
2
together in the tank
under high pressure creates the soda water. The quality of
carbonation (percent of CO
2
mixed in the water) increases
as the water temperature decreases and exposure time
increases.
The water level in the carbonator tank is controlled by a
water level control in the tank. This control turns the pump
motor off and on to maintain a preset level of liquid in the
tank. The water level control may be electronic probes or a
mechanical float.
SYRUP DELIVERY SYSTEM
Your syrup location can vary depending on the volume of
beverages served and ease of accessibility. Your beverage
system may sit in a back storage room or under the counter
of the dispenser. Configurations are almost limitless.
Check the temperatures expected for the storage location.
Adverse temperatures can affect the storage and quality of
beverage products. It is recommended the temperature of
storage location must not fall below 40°F (4°C) or rise above
90°F (32°C).

1. Incoming tap water – must be at a minimum dynamic
pressure of 40 psi and maximum static pressure of
55psi.
2. Carbonator Water pump motor – Powers the water
pump. The water pump motor is part of the carbonator
pump deck.
3. Carbonator Water pump – Pumps tap water into
the carbonator tank. The water pump is part of the
carbonator. The incoming water for the carbonator
must be first run through the pump before connecting
to the proper cold plate inlet.
4. Internal/External Carbonator tank – Combines CO
2
gas and tap water to form carbonated water. The
“carbonator” is the carbonator tank, water pump and
water pump motor.
5. CO
2
cylinder – Holds highly pressurized carbon dioxide
(CO
2
). The CO
2
cylinder is a steel or aluminum cylinder
tank. CO
2
gas flows through the primary pressure
regulator.
6. BIB pressure gauge – Set for a minimum of 60 psi.
Indicates CO
2
pressure going to B-I-B pumps.
7. Primary pressure regulator – Lowers the CO
2
gas
pressure to 100 psi, so the CO
2
gas will be at the proper
pressure to enter the carbonator regulator.
