Grounding Instructions
Risk of electrical shock. Connect to a properly
grounded outlet only.
This appliance must be grounded. In the event of
malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a cord
having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into an
appropriate outlet that is properly inst alled and grounded
in accordance with all local codes and ordinances.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment grounding conductor. If repair or
replacement of the cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal. Check with a qualified electrician or
serviceman if the grounding instructions are not
completely understood, or if in doubt as to whether
the appliance is properly grounded. Do not modify
the plug provided with the appliance — if it will not fit
the outlet, have a proper outlet installed by a
qualified electrician.
When using electric appliances, basic precautions
should always be followed, including the following:
a. Read all the instructions before using the
appliance.
b. To reduce the risk of injury, close
supervision is necessary when an
appliance is used near children.
c. Do not contact moving parts.
d. Only use attachments recommended or
sold by the manufacturer.
e. Do not use outdoors.
f. For a cord-connected appliance, the
following shall be included:
• Do not unplug by pulling on cord. To
unplug, grasp the plug, not the cord.
• Unplug from outlet when not in use and
before servicing or cleaning.
• Do not operate any appliance with a
damaged cord or plug, or after the
appliance malfunctions or is dropped or
damaged in any manner. Contact the
nearest authorized service facility for
examination, repair, or electrical or
mechanical adjustment.
g. For a permanently connected appliance —
Turn the power switch to the off position
when the appliance is not in use and before
servicing or cleaning.
h. For an appliance with a replaceable lamp —
always unplug before replacing the lamp.
Replace the bulb with the same type.
i. For a grounded appliance — Connect to a
properly grounded outlet only. See
Grounding Instructions.

ICE RECOMMENDED FOR DISPENSING
Dispensers are designed to dispense hard, cube ice up
to one-inch square. The ice shapes and sizes listed
above are recommended for dispensing. Warm “Super
Cooled” Ice Before Dispensing: “Super Cooled” ice is not
recommended for dispensing. “Super cooled” ice is ice
that has been stored in freezers below 32°F. Should it be
necessary to temporarily use “super cooled” ice, allow
the ice to warm at room temperature for 25 to 30
minutes before placing the ice in the dispenser.
ICE STORAGE AND DISPENSING
As the customer presses the rocking chute, the arm at
the top left rear of the chute pushes upward on the door
lock. The door opens until it contacts the stops in the
mounting brackets. The plastic arm on the ice ch ute also
activates the lever of the ice dispensing switch. When
activated, the micro switch starts the gear motor. The
gear motor turns the paddle wheel and agitator arm.
The paddle wheel carries ice. Periodic agitation is
standard on the 30" and larger dispensers. During
periodic agitation, the paddle wheel and agitator turn for
approximately three seconds every three and one halfhours. The door lock prevents ice from being dispensed
during the agitation cycle.
BEVERAGE VALVES
Post-mix beverage valves are designed to precisely
meter the flow of both water and syrup to obtain the
proper mixing ratio. The syrup and soda wate r
components of the post-mix beverage are mixed as they
leave the beverage valve.
ROCKING CHUTE ICE DISPENSING
As the customer presses the rocking chute, the arm at
the top left rear of the chute pushes upward on the door
lock. The door opens until it contacts the stops in the
mounting brackets. The plastic arm on the ice chute also
activates the lever of the ice dispensing switch. When
activated, the micro switch starts the gear motor. The
gear motor turns the paddle wheel and agitator bar.
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

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
mix, and a water level control.

Operation
Carbon Dioxide (CO
) leaves the storage tank and
2
arrives at the carbonator tank through the gas inlet.
Water supply enters the carbonator pum p 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
and the
2
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
together in the tank
2
under high pressure creates the soda water. The quality
of carbonation (percent of CO
mixed in the water)
2
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
Y our syrup location can va ry 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 p aid 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 othe r.
B-I-B
The Bag-In-Box system refers to a plastic disposab le
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 th e sy r up
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.

chute bracket to the door. The distance between the two
must be no more than 1/4” (0.64 cm), but no less than
1/16” (0.16 cm).
The left side of the rocking chute has a tab that pushes
up on the ice delivery switch. To adjust it, use needle
nose pliers and bend the arm of the switch up or down in
order to change the point where the tab makes contact
with the switch arm.

below will assist you in continued trouble-free operation
of your unit.
1. Conduct daily maintenance of the machine.
2. Perform monthly maintenance of the machine.
3. Perform periodic maintenance and sanitizing of
beverage system.
4. Do not overfill the dispenser bin with ice.
5. Do not allow the dispenser to sit for prolonged
periods of non use with ice in the bin.
6. Most ice dispenser service problems are caused by
low usage of the ice dispenser.
7. Do not allow ice to remain in the bin more than a day
in order to prevent ice from freezing together and/or
stagnant ice.
Possible excess ice storage reasons:
• Storage capacity exceeds daily requirements.
• Low demand during the off season.
• Dispenser oversized with future growth in mind.
Lower ice storage to meet one day’s needs. If you
manually fill ice, fill only with the appropriate amount of
ice. Fill the dispenser with fresh ice each morning. Do
not fill the dispenser at night just before shut down. Ice
cubes can freeze together if not dispensed.
