Sequence of Operation
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.
Flake or “nugget” ice is NOT to be dispensed from the
Selectable Ice Unit. The SV Selectable Ice dispenser comes
equipped with the selectable ice feature so you are able to
choose between cubed or crushed ice making the addition
of a flake/nugget icemaker unnecessary.
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 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 arm.
The paddlewheel 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 half-hours. The door lock
prevents ice from being dispensed during the agitation cycle.
SELECTABLE ICE SEQUENCE OF OPERATION
On units equipped with the selectable ice option, as a
customer presses the ice chute or pushes the sanitary lever
towards the unit with their cup, with “Crushed Ice” selected
on the ice selection pad, the rocking chute door lifts and
actuates micro switch which initiates the crushed ice
dispensing process. The micro switch is activated when the
lever is approximately 1/4 inch from reaching the splash
panel of the unit. When activated, the micro switch starts the
gear motor and ice crusher motor.
The gear motor turns the paddle wheel and U-bar agitator.
The paddle wheel carries ice to the crusher assembly. Once
the ice reaches the crusher housing, four stationary blades
and three rotating blades crush the ice and push it through
the opening in the ice crusher housing. The crushed ice then
falls through the opening into the ice chute, and into the
customer’s cup. If the merchandiser is removed no power is
available to the crusher or gear motor and no ice can be
crushed and/or dispensed.
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 water components of the post-mix
beverage are mixed as they leave the beverage valve.
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.
