concentrate level falls below the sensor on the side of the concentrate container the current flow is
interrupted. The electronic control PCB senses the current flow decrease and turns the low level
beeper on when the Dispense paddle is operated in the
SERVE mode. The low level beeper will
not sound in the FLUSH mode.
3.4 ELECTRONIC CONTROL SYSTEM
The electric cord supplies 115 VAC to the compressor, condenser fan motor and agitator motor.
Each component has circuit protection with an automatic reset feature. The only manual reset is a
0.5 amp circuit breaker on the primary side of the control transformer accessible on the front of the
control panel. The control transformer primary is switched by the key switch and supplies power to
the pump motors, solenoids and paddle sensors via the control PCB.
All the logic functions and voltages required to operate the entire dispensing/flushing system are
provided by the control PCB. There is only one (1) motor speed control circuit, but this circuit has
two (2) available speed settings. This allows one dispensing station to operate at a time, and
enables each station to dispense at a different
o
Brix. The FLUSH cycle (flush and paddle depressed
simultaneously) forces the motor to run at the maximum speed to facilitate thorough flushing. There
are three (3) light emitting diodes (LEDs) visible on the control PCB (for access, see Section
1.10.D). These LEDs assist with Troubleshooting and Servicing (see Section 8).
3.5 DISPENSING PADDLE SYSTEM
The dispensing paddle has an integrally sealed permanent magnet which activates the sensor
behind the splash plate when the paddle is depressed. This causes the electronic system to
activate the water solenoid and concentrate pump allowing the unit to dispense product. The
dispensing paddles are removable (without tools) for cleaning. Paddles can be removed by
squeezing together the top edges of each paddle.
3.6 FLUSH SYSTEM
When the mode switch is held in FLUSH position and a paddle is depressed, the electronic system
opens the flush solenoid and allows water to flow to the check valve on the concentrate container
and simultaneously to operate the concentrate pump. Water flows through the check valve, the
concentrate pump, and the spout. The check valve positioned at the concentrate container prevents
flush water from entering the concentrate container.
3.7 REFRIGERATION SYSTEM
An ice bank is formed and maintained on the copper tube evaporator located in the water bath
compartment of the tank assembly. Water is continually circulated by the agitator motor across the
ice bank and around the copper water coil. Water temperature is maintained at 32
o
F (0
o
C).
Because the water compartment and concentrate compartment are an integral aluminum die cast-
ing,
the
concentrate compartment is maintained at a constant 35
o
F (1.7
o
C) temperature. When product is
dispensed, water is drawn through the copper water coils and chilled. As the ice bank is depleted,
the ice bank control senses that the ice is melting and causes the compressor and condenser fan
motor to start. When the ice bank is rebuilt the control shuts off the compressor and condenser fan
motor. The compressor and condenser fan motor will operate periodically even though no drinks
are being dispensed in order to maintain the ice bank. If the unit is unplugged or power disrupted
while operating, the compressor will not restart for a period of time during which the refrigerant
pressures equalize (approximately 5 minutes). This feature protects the compressor from
premature failure.
4. RELOCATING OR SHIPPING UNIT
4.1 REMOVING AN OPERATING UNIT
A. Perform FLUSH operation on each side of unit until a clean stream of water is being dispensed.
B. Remove concentrate containers, clean thoroughly and replace.
C. Shut off inlet water supply. Disconnect inlet water tube from bottom of unit. About 6 ounces
(177.4 ml) of water will drain out of unit as the vacuum breaker opens allowing air into system.
D. Depress each dispensing paddle. This allows additional air into system and will cause a few
more ounces (ml) of water to drain from unit.
