A. Turn key switch ON.
B. Using a cup, activate each dispensing valve until a steady flow of water is obtained.
C. Turn key switch OFF.

1.8 LOAD MINUTE PAKS

®

A. Remove lid over concentrate compartment.
B. Minute Paks

®

must be completely thawed and shaken thoroughly before loading.

C. Load each Minute Pak

®

per the flavor label on the front of the unit.

D. Replace check valves (yellow elbow) in concentrate containers using a rotating movement while

pushing down.
E. Replace lid on top of unit.

1.9 PRIMING CONCENTRATE PUMPS

A. Turn key switch ON.
B. Depress the Sold Out Reset button.

NOTE

An initial eight (8) to ten (10) ounces (236.6 ml to 295.7 ml) of water will be dispensed before

the concentrate/water mixture reaches the spout.

C. Hold cup under spout and depress the dispensing paddle.

1.10 ADJUST WATER TO CONCENTRATE RATIO (°BRIX)

A. Install dispensing nozzle.
B. Inlet water is distributed through a common water system with the regulator pressure preset at

25 PSIG. With a proper water source, each spout will dispense approximately 1.2 ounces

(35.5 ml) of water per second (see SPECIFICATIONS on Cover page). When mixed with

concentrate (5 to 1 ratio), the finished drink will be dispensed at 1.5 ounces (44.3 ml) per

second.
C. Because the ratios are factory preset electronically, they may require an adjustment at time of

2

installation depending on the product being dispensed. This can be accomplished by using a
refractometer as follows:

1. Dispense a 5 or 6 ounce (147.9 or 177.4 ml) cup of product and discard.

2. Dispense a 5 or 6 ounce (147.9 or 177.4 ml) cup of product and stir thoroughly.

3. Using a refractometer, read the ratio (°Brix). Adjust as necessary as explained in step D
below and re-Brix.

D. To adjust the °Brix, remove the Sold Out Plates from the front panel. Use a standard (straight)

slot pocket screwdriver inserted CAREFULLY through the hole in the front panel and adjust the
°Brix (motor speed) controls (see Figure 1).

To adjust the °Brix, turn the adjusting control as follows:

Decrease °Brix (less concentrate)............................................................Clockwise

Increase °Brix (more concentrate)..............................................Counter Clockwise

E. To set unit that has not been factory preset for a certain product, adjust °Brix and change

product plate on front panel.

F. In some locations, the water supply pressure may be so low (or may fluctuate so much) that a

25 PSIG 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 25 PSIG flowing. To reset regulator, refer to Section 7.8 K-Q. Readjust
°Brix as necessary.

B. Intermittent Lock out

Every precaution has been taken to produce a Sold Out Feature which will operate properly with all of
the Minute Maid

® products. However, it is possible that an individual machine may lock out

inadvertently. Should the machine lock out while product remains, simply press the "RESET" button.

If the machine continues to lock out, check the following:

• Make sure that the package is thoroughly shaken and that the pump has been fully primed (no air

bubbles present in concentrate tubing).

• Concentrate Tubes - if the tubes are heavily stained from the product, the tube(s) must be changed
out.

• Air Leaks - check that the concentrate tubes fit snugly onto the check valves and pump connections.
If there is doubt as to the integrity of the connection, replace the tubing. Check the fit of the check
valves into the concentrate container or Minute Pak®; it should be snug and require effort to
remove. If the o-rings are worn, they must be replaced. Inspect the check valves to be sure that they
are not missing internal parts. If so, replace the check valves. Perform the test procedure in Section

2.3.C (below), once all parts have been inspected and/or replaced.

C. Test Procedure

Should you desire to determine if the Sold Out Feature is working, you may perform the follow­ing procedure:

1. Load Product into machine.

2. Press "RESET" button.

3. Dispense for 20 continuous seconds.

NOTE:

The 20 second continuous dispense is ONLY required for testing.

4. The Sold Out Feature should now be armed. To test, remove the check valve from the
concentrate package. Then dispense until lock out alarm sounds (this simulates an empty
package).

5. When alarm sounds, replace the check valve and press "RESET" button to return to moni­toring condition.

6. If alarm does not sound, repeat test procedure. If alarm does not sound after repeating the
test procedure several times, contact the Service Center.

D. Disabling of Sold Out Feature

The Sold Out Feature can be disabled by pressing the "Flush" button three (3) times (in rapid

succession). The dispenser will follow with three (3) short beeps.

E. Enabling of Sold Out Feature

Press the "RESET" button to enable the Sold Out Feature. Dispenser will follow with three (3)
short beeps.

3. PRINCIPLES OF OPERATION

3.1 WATER SYSTEM

Inlet water is distributed through the strainer to the regulator which reduces the inlet water pressure
to 25 PSIG. Water is fed from the regulator through a stainless steel tube (embedded in the
insulation of the tank assembly) and into the copper water coil where it 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 solenoids.
When a dispensing valve is activated, the corresponding water solenoid opens allowing water to
pass into the spout and mix with concentrate.

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.

6

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 (9) seconds of dispensing [in three (3) second continuous intervals] will take
the 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

W

ARNING

THE KEY SWITCH DOES NOT DISABLE THE HIGH VOLTAGE (115 VAC) TO THE
TRANSFORMER PRIMARY.

The electric cord supplies 115 VAC to the compressor, condenser fan motor, agitator motor and
control transformer. 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 bottom right of the control box behind the splash plate. The control transformer
secondary is switched by the key switch and supplies power to the pump motors, solenoids and
paddle sensors via the control printed circuit board (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 only one dispensing station to operate at a time, but
enables each station to dispense at a different °Brix. There are three (3) light emitting diodes (LEDs)
