As product is dispensed, ice is depleted, the ice bank control senses that the ice is melting and
turns the compressor and condenser fan on. When the ice bank is rebuilt, the ice bank control turns
the compressor and condenser fan motor off. The compressor will periodically run to maintain the
ice bank even though no drinks were dispensed. If power to the unit was disrupted while the
compressor was running, the compressor will not restart immediately when power is re-established.
There is a restart delay circuit [approximately five minutes] built into the ice bank control to prevent
the compressor from starting under pressure. This feature protects the compressor from premature
failure.
Ice water is circulated through the cooling coil at the rear of the product compartment with a pump
at the bottom of the ice bath. Cool air is circulated in the product compartment by four small fans
mounted to a cooling coil in the container compartment.

GROUNDING WARNING
THE DISPENSER MUST BE PROPERLY ELECTRICALLY GROUNDED TO AVOID
SERIOUS INJURY OR FATAL ELECTRICAL SHOCK. THE POWER CORD HAS A THREE-PRONG GROUNDED
PLUG. IF A THREE-HOLE GROUNDED ELECTRICAL OUTLET IS NOT AVAILABLE, USE AN APPROVED METHOD TO
GROUND THE UNIT. FOLLOW ALL LOCAL ELECTRICAL CODES WHEN MAKING CONNECTIONS. EACH
DISPENSER MUST HAVE A SEPARATE ELECTRICAL CIRCUIT. DO NOT USE EXTENSION CORDS. DO NOT
CONNECT MULTIPLE ELECTRICAL DEVICES ON THE SAME OUTLET.
ADVERTENCIA, PUESTA A TIERRA
ES NECESARIO PONER A TIERRA ELÉCTRICAMENTE EL
DISPENSADOR PARA EVITAR LESIONES GRAVES E INCLUSO ELECTROCHOQUES FATALES. EL CABLE DE
ALIMENTACIÓN TIENE UN ENCHUFE PUESTO A TIERRA DE 3 CLAVIJAS. SI NO SE DISPONE DE UN TOMA
ELÉCTRICO CONECTADO A TIERRA DE TRES AGUJEROS, USE UN MÉTODO APROBADO PARA PONER A TIERRA
LA UNIDAD. AL HACER LAS CONEXIONES, RESPETE TODOS LOS CÓDIGOS ELÉCTRICOS LOCALES. CADA
DISPENSADOR DEBE TENER UN CIRCUITO ELÉCTRICO INDEPENDIENTE. NO USE CABLES DE EXTENSIÓN. NO
CONECTE VARIOS DISPOSITIVOS ELÉCTRICOS AL MISMO TOMACORRIENTE.
EXIGENCES DE MISE À LA TERRE
LA DISTRIBUTRICE DOIT ÊTRE MISE À LA TERRE ÉLECTRIQUEMENT
CORRECTEMENT POUR ÉVITER DES BLESSURES GRAVES OU UNE DÉCHARGE ÉLECTRIQUE MORTELLE. LE
CORDON D’ALIMENTATION A UNE FICHE À TROIS BRANCHES MISE À LA TERRE. SI AUCUNE PRISE DE
COURANT ÉLECTRIQUE À TROIS TROUS N’EST DISPONIBLE, UTILISEZ UNE MÉTHODE APPROUVÉE POUR
METTRE L’UNITÉ À LA TERRE. RESPECTEZ TOUS LES CODES ÉLECTRIQUES LOCAUX LORSQUE VOUS FAITES
DES CONNEXIONS. CHAQUE DISTRIBUTRICE DOIT AVOIR UN CIRCUIT ÉLECTRIQUE SÉPARÉ. N’UTILISEZ PAS
DE CORDONS PROLONGATEURS. NE BRANCHEZ PAS PLUSIEURS APPAREILS ÉLECTRIQUES À LA MÊME PRISE
DE COURANT.

The unit’s power cord plugs directly into the power supply located on the front left corner of the
dispenser behind the splash plate. Jumper harnesses from the power supply provides 32 VDC to
the CPU and line voltage to the refrigeration deck.
The dispenser’s electronic systems control all of the dispenser functions. The refrigeration system
is controlled by an electronic ice bank controller located on the compressor deck. A printed circuit
board, located in the doors, operates the front display panel and relays control signals to the control
box. All other functions are controlled by the electronic control box located behind the splash plate.
A. Water Solenoid/Flow Meter
When the dispense mode is activated, the solenoid valve opens and water flows through a
digital flow meter which sends a signal to the microprocessor. The microprocessor continuously
monitors the flow rate and adjusts the concentrate drive motor to correct for any variations in
flow rate due to pressure variations.
B. Electronic Ice Bank Controller
The ice bank controller housing is mounted on the compressor deck. It connects to a probe that
is mounted to the evaporator coil. The probe allows the controller to measure the difference in
resistance between water and ice, and shuts the compressor off when the ice bank grows
enough to cover the probe. The printed circuit board inside the housing uses an edge connector
so that it can be easily serviced.
C. Product Compartment Temperature Sensor
A temperature sensor is located below the cooling coil inside the product component. Product
compartment temperature is displayed on the product compartment door.
