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 or rise above 90°F.
RACKING
Regardless if you are working on a B-I-B or Figal
system, a place will be designated for placement of the
product. A rack (or shelf) system affords systematic
placement and complete usage of the beverage paid for.
The B-I-B rack allows the boxes to lay properly for syrup
dispersal. Please check with your B-I-B syrup supplier.
Some boxes must be slightly tilted down, while others
may be in virtually any position. The Figal tank rack
keeps the newer and full tanks organized at one end of
the beverage line with the partial tanks at the other.
B-I-B
The Bag-In-Box system refers to a plastic disposable
bag. The B-I-B normally contains 5 gallons of syrup,
however some locations offer 2-1/2 gallon B-I-B units.
This plastic bag is then held inside a cardboard or other
container. B-I-B systems are for post-mix applications
only.
PUMPS
The syrup in a B-I-B system is delivered to the beverage
system through gas operated pumps. These pumps
extract the syrup out of the bags, forcing the syrup
throughout the system.
AUTO BAG SELECTORS
These are used on higher volume B-I-B systems where
two or more bags of the same product are connected to
one pump and one system. An auto bag selector is
essentially a valve that automatically changes from one
bag (or series of bags) to another bag (or series of bags)
of syrup as the bags empty, allowing a constant flow of
product.
AGITATION TIMER
The timer is non-adjustable and is set to agitate the ice
for 3 seconds every 3.5 hours. Activating the dispenser
will reset the timer. After 3.5 hours of non-use, the timer
will energize the dispenser motor.
The LED tells the technician in which mode the timer is
operating. Rather than a jumper pin, this timer has a
female spade connector that must be connected to
terminal number 6.
When this jumper is in place, the LED will blink at
one-second intervals, this is the run mode.
When the jumper is open, the LED will flash every
0.4 second. This is the test mode and the timer will cycle
every 55 seconds in test mode. If the timer is left in test
mode, it will automatically reset to run mode.
