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 set 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 should not fall below 40°F
(4°C) or rise above 90°F (32°C).
BACK ROOM PACKAGE
1.
Incoming tap water
- should be at a minimum
dynamic pressure of 40 psi and maximum static
pressure of 70 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 75 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.
8.
Lowered outgoing pressure -
Set for 75 psi.
Gauge indicates lowered outgoing pressure from the
CO
2
cylinder after being routed through the primary
pressure regulator at 100 psi.
9.
Secondary pressure regulator -
Lowers the CO
2
gas pressure before the CO
2
gas flows to the syrup
pump. CO
2
pressure activates the syrup pump.
10.
Syrup pump -
Draws syrup out of the bag-in-box
syrup package. Syrup flows through the syrup lines
to the dispenser for chilling, then dispensing. There
is a syrup pump for each bag-in-box syrup system.
11.
Bag-In-Box syrup cartons -
Box which contains a
plastic bag, filled with syrup.
