container from unit. C. Remove yellow plug from agitator deck. D. Using a funnel or tube, fill with water until water flows out of overflow hole into concentrate

container compartment. Facing the front of the unit, the overflow hole is in the rear wall of the

concentrate container compartment. The overflow water will drain into the drip tray. E. Replace yellow plug.

1.6 CONNECTING TO ELECTRICAL POWER

ARNING

THIS UNIT MUST BE PROPERLY ELECTRICALLY GROUNDED TO AVOID POSSIBLE FATAL ELECTRICAL SHOCK OR SERIOUS INJURY TO THE OPERATOR. THE POWER CORD IS PROVIDED WITH A THREE PRONG GROUNDED PLUG. IF A THREE-HOLE GROUNDED ELECTRICAL OUTLET IS NOT AVAILABLE, USE AN APPROVED METHOD TO GROUND THE UNIT.

Plug unit power cord into electrical outlet. Compressor and condenser fan motor will run until unit builds a complete ice bank. Agitator motor will run continuously.

1.7 PURGING UNIT OF AIR

A. Raise front cover and turn key switch ON. B. Using a cup, actuate each dispensing paddle until a steady flow of water is obtained. C. Turn key switch OFF.

1.8 FILLING CONCENTRATE CONTAINER

A. Thoroughly clean concentrate containers in warm soapy water. Rinse well. B. Fill each concentrate container with concentrate. Refer to Specifications (page iii) for capacity of

concentrate containers. C. Replace concentrate containers in unit. Be sure they are properly located and seated all the

way down. Facing unit, each concentrate container MUST have filler tube and product sensors

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

pushing down. E. Replace both lids on top of unit.

1.9 PRIMING CONCENTRATE PUMPS

A. Turn key switch ON. B. Press and hold the mode switch to the FLUSH position. C. Hold cup under spout and depress the dispensing paddle until a solid flow of water is obtained

through the concentrate pump.

D. Release the mode switch. E. Hold cup under spout and depress the dispensing paddle. 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 nozzle.

1.10 ADJUST WATER TO CONCENTRATE RATIO (

BRIX)

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

25 PSIG (1.76 kg/cm

). With a proper water source each spout will dispense approximately

1.2 ounces (35.5 ml) of water per second. When mixed with concentrate (4 to 1 ratio), the finished drink will be dispensed at 1.5 ounce (43 ml) per second.

C. The unit is factory preset (electronically) for the following products and ratios.

LEFT RIGHT

PRODUCT RATIO PRODUCT RATIO

Grapefruit 4:1 Orange 4:1

NOTES: Because the ratios are factory preset electronically, they are not exact and may

require a slight adjustment at the time of installation. 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 Section 1.10.D below) and re-Brix.

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. On the main control printed circuit board (PCB) are two adjusting knobs

which control the

Brix of the left and right sides. The control on the left side (facing the control

panel) controls the left motor and the right control is for the right motor (refer to Figure 1).

Figure 1 - Motor Speed Controls and Flush Switch.

To adjust the

Brix turn the adjusting control as follows:

Decrease oBrix (less concentrate)............................................ Counter Clockwise

Increase

Brix (more concentrate)....................................................... Clockwise

E. To set unit that has not been factory preset for a product, adjust oBrix 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/cm

) 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 oBrix 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/cm

) flowing. To reset regulator, refer to

Section 6.13.K-Q.

G. Readjust

Brix as necessary.

H. Slide control panel into control housing and tighten screws finger tight. Be sure control panel is

properly seated in control housing.

1.11 CONCENTRATE LOW LEVEL INDICATOR

A. The unit is equipped with a concentrate low level indicator system. B. Beeper (dispensing only). At low level, the beeper will emit sound only while a drink is being

dispensed.

1.12 PRODUCT PLATES

Install the proper product plates in the holes on the front panel to indicate the product being served.

2. OPERATING UNIT

2.1 REFILLING CONCENTRATE CONTAINERS

A. Remove top cover. B. Place opened can of COMPLETELY THAWED concentrate into concentrate container. C. When the concentrate low level indicator is sounding, the concentrate container can be refilled

with the following quantity.

ARNING

REMOVE SANITIZING SOLUTION FROM DISPENSER AS INSTRUCTED. RESIDUAL SANITIZING SOLUTION LEFT IN SYSTEM COULD CREATE HEALTH HAZARD.

19. Test dispenser in normal manner for proper operation. Taste dispensed product to ensure there is no off-taste. If off-taste is found, additional flushing of dispensing system may be required.

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 (1.76 kg/cm

). 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. 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 paddle is depressed, the corresponding water solenoid opens allowing water to pass into the spout and mix with concentrate.

3.2 CONCENTRATE SYSTEM

When the dispensing paddle is depressed, 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 32oF. 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 concentrate containers have two integral stainless steel spring loaded ball sensors (on bottom and side) of containers. When the concentrate container is in the unit, the sensors contact the corresponding contacts in the side and bottom of the concentrate compartment. When the concentrate level in the concentrate container is above the sensor on the side of the concentrate container, a very small AC current is conducted by the concentrate between the sensors. When the

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

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

F (0oC). Because the water compartment and concentrate compartment are an integral aluminum die casting, the concentrate compartment is maintained at a constant 35

F (1.7oC) 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.

WARNING

IF UNIT IS TO BE TRANSPORTED OR STORED WHEN AMBIENT TEMPERATURE IS 32oF (0

C) OR LOWER, STEPS C AND D MUST BE PERFORMED TO PREVENT THE WATER

SYSTEM FROM FREEZING AND DAMAGING UNIT. DO NOT USE CO

2 GAS TO PURGE WATER

FROM UNIT AS IT WILL CAUSE A HEALTH HAZARD.

E. Turn key switch OFF. F. Unplug unit power cord from electrical outlet. G. Remove agitator deck and using plastic tubing, siphon water out of ice bath compartment. It will

be necessary to pour about 6 ounces (177.4 ml) of warm water (do NOT use extremely hot water) into the retainer that holds the ice bank control sensing bulb. This defrosts the ice around the retainer allowing the agitator deck to be removed. Replace agitator deck and secure with nuts.

H. Remove drip tray and cup rest. Clean and replace. Wipe unit exterior surfaces with a clean

damp cloth.

4.2 TRANSPORTING UNIT

The best method of handling and transporting a unit is to remove legs and secure 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 the original packing material.
