ESCORT III
Left Middle Right
Ratio 6:1 5:1 5:1
NOTES: Because the ratios are factory preset electronically, they are not
exact and may require a slight adjustment at time of installation.
This can be accomplished by using a refractometer as follows:
1. Dispense a 5 or 6 ounce (147.9 to 177.4 ml) cup of product
and discard.
2. Dispense a 5 or 6 ounce cup (147.9 to 177.4 ml) of product
and stir thoroughly.
3. Using a refractometer read the oBrix. Adjust as necessary as
explained in 1.10.D below and re-Brix.
Factory PreSet Select, Ratio, Product
Table 1
D. To adjust the °Brix, loosen two (2) screws on face of control panel until control panel can be
pulled partially out of control housing. Screws are captive and can be used to pull control panel
from control housing.
(1) Each spout of the unit is controlled by an independent Drive Printed Circuit Board (PCB)
plugged into the Master PCB. The driver PCB has adjusting knobs which control the °Brix
of the product selections.
(2) To adjust the °Brix turn the adjusting control as follows:
INCREASE
SELECTOR TAB
DRIVER PC BOARD
MOTOR OVER-CURRENT (YELLOW)
12 VOLTS (GREEN)
MOTOR VOLTS (RED)
SEL 2
SEL 1
Decrease °Brix..............Turn Counter
(less concentrate) Clockwise
Increase °Brix................Turn Clockwise
(more concentrate)
E. To set a unit that has not been factory preset for a
product, adjust °Brix and change product plate on
control panel.
F. In some locations, the water supply pressure may be so
low or may fluctuate so much that a 25 PSIG
(1.76 kg/cm2) flowing water pressure cannot be
maintained. As a result, the unit will not dispense a
product at the proper °Brix. In this event, the
regulated water pressure should be reduced below the
local inlet water supply pressure so that a
proper °Brix can be maintained. Reducing the regulated
water pressure will reduce the finished product flow rate.
Normally, the minimum recommended setting is 15 PSIG
(1.06 kg/cm2) flowing. To reset the regulator, refer to
Section 6.9, items K-Q.
G. Readjust °Brix as necessary.
H. Slide control panel into control housing and tighten

3. PRINCIPLES OF OPERATION
3.1 WATER SYSTEM
Inlet water is distributed through the strainer to the left and right regulators, which reduces the inlet
water pressure to 25 PSIG (1.76 kg/cm2).
Water is fed from the regulator through stainless steel tubes (embedded in the insulation of the tank
assembly) and into the copper water coil, where the water is chilled to below 40°F (4.4°C). Water
is then fed past a vacuum breaker through a stainless steel tube (embedded in the insulation of the
tank assembly) to the front of the tank assembly and into the water solenoid. When a valve is
activated, the corresponding water solenoid opens allowing water to pass into the spout and mix with
concentrate.
Each water system is completely independent of the other. On the Escort Ill units, products can
be dispensed singularly or simultaneously through the right and either left or middle spouts
without a change in °Brix. When the inlet water is disconnected from the unit, the vacuum breaker
will open automatically allowing water to drain out of the unit, thus preventing a freeze up when
transported or stored at ambient temperatures below 32°F (0°C).
3.2 CONCENTRATE SYSTEM
When the dispensing valve is activated, concentrate is drawn from the bottom of the concentrate
container, up the integral dip tube and through the check valve and concentrate tube, to the inlet of
the concentrate pump.
It is metered by volume and pumped into the spout where it mixes with the water. The temperature
of the concentrate does not effect the °Brix as long as it is above 32°F (0°C). The volume output of
the concentrate pump is controlled electronically and can be adjusted to change the °Brix.
3.3 CONCENTRATE LOW LEVEL INDICATOR SYSTEM
The dispenser is equipped with an infrared sensor on each concentrate tube that senses the
difference in light density that is passed through the tube. The unit reads juice characteristics and
obtains a measurement (Learn Mode). If the unit senses a change in density, indicating a bubble or
lack of concentrate while dispensing, the unit will go into Lock-Out Mode. When the unit is in
Lock-Out Mode, it will disable the valve and turn on the Sold-Out LED. It will also beep if you
depress the dispense button while in Lock-Out Mode. To enable dispensing, reload the concentrate
container and press the reset button. This will clear the lock-out and put the unit into Learn Mode.
NOTE:
The Lock-Out Mode can be cleared by cycling power (key switch). When power is restored the unit
will not go into Learn Mode.
A. If the flush switch is depressed, the unit will go into flush wait mode. In this mode the unit will
not lock out. Nine seconds of dispensing [in three (3) second continuous intervals] will take the
6
dinecompany.com

unit out of Flush Wait Mode.
B. If the valve does not dispense for over one hour, the unit will go into Inactivity Wait Mode. In
this mode the unit will not lock out. It will stay in this mode until a three (3) second continuous
dispense occurs.
C. The unit enters Learn Mode when the reset switch is depressed. The unit will beep once when
entering Learn Mode. (Note: If the reset switch is depressed and the unit does not beep, it is
already in Learn Mode). This clears the lock-out (shuts off the red LED, disables audible alarm,
and enables dispensing).
D. Pre-learn dispense - The unit will wait for 15 seconds of dispensing [in three (3) second
increments]. This delay ensures that concentrate is in the sensor region of the tube before
learning the concentrate.
E. Learn -The unit will "learn" the characteristics of whatever is in the sensor region of the tube
when a dispense (of at least one second) occurs after the pre-learn dispense is finished.
NOTE:
If the flush button is pressed after the reset/learn button, the unit will have to clear the Flush Wait
Mode before it will learn the concentrate. The Flush Wait Mode is cleared by three (3) dispenses
of at least three (3) seconds each. Since the pre-learn dispense requires five (5) dispenses of
at least three (3) seconds each, it should have no effect on the learn unless several seconds of
dispensing occur in the pre-learn dispense mode before the flush switch is pressed. In a worst
case scenario, it could take an additional nine seconds of dispensing before the learn occurs if
the flush switch was pressed just before the pre-learn dispense was finished.
F. The unit may be put into or out of Disable Lock-Out Mode by depressing the flush switch three
(3) times in less than two (2) seconds. When entering/leaving Disable Lock Out Mode, the unit
will beep three (3) times. In Disable Lock Out Mode, the dispenser will operate without the Low
Level/Sold Out features.
3.4 ELECTRONIC CONTROL SYSTEM
Electrical power is fed into the transformer cabinet assembly, which contains independent Class II
energy limiting step down transformers.
Each transformer is protected by a resettable circuit breaker on the primary side of the transformer.
Each transformer feeds 15.3VAC to a driver PCB which controls one spout of the unit. Each driver
PCB is independent of the other. The driver PCB plugs into an edge connector of the control panel
PCB. Failure of a transformer or driver PCB on one spout does not effect the operation of the other
spout of the unit.
Current supplied to the various devices (e.g., solenoids, sensors, lights, pump motor, etc.) by the
driver PCB does not exceed 15VDC. With the exception of the pump motor, any short circuit of one
or more of the devices controlled by the driver PCB will cause the driver PCB to shut OFF and cease
functioning. When the short circuit is corrected by repair or replacement of the faulty device, the
driver PCB will automatically reset and begin functioning. This is also true of the pump motor,
except that to reset the driver PCB, the key switch must be turned to the OFF position for
30 seconds and then turned back to ON.
When the dispensing valve is activated, the driver PCB activates the water solenoid and the pump
motor. The electronic system continuously monitors the pump motor and maintains exact speed
(°Brix) regardless of the load on the pump motor. °Brix is changed by turning the adjusting knob on
the driver PCB as described in Section 1.10C.
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 the top edges of each paddle together.
3.6 FLUSH SYSTEM
When the flush switch is held in position, the electronic system opens the flush solenoid and allows
7

water to flow to the check valve on the concentrate container and simultaneously operates 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°F (0°C).
Because the water compartment and concentrate compartment form an integral aluminum die
casting, the concentrate compartment is maintained at a constant 35°F (0°C) temperature. When a
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 is disrupted while
operating, the compressor will not restart for a period of time during which the refrigerant pressures
equalize [approximately five (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.

the remaining water and replace agitator deck and secure with nuts.
H. Remove drip tray and cup rest. Clean and reinstall. Wipe exterior surfaces of unit with a clean
damp cloth.
4.2 TRANSPORTING UNIT
The best method of handling and transporting a unit is to remove the legs and secure the unit to a
plywood shipping base. If it is to be handled and transported with the legs assembled to the unit,
special care should be taken not to damage unit. DO NOT LAY UNIT ON SIDE OR BACK.
4.3 SHIPPING UNIT
If a unit is to be shipped by a common carrier, it must be secured to the plywood shipping base and
repacked in the original carton with the inner packaging material. For this reason, it is wise to retain
