3. OPERATING PRINCIPLES

3.1 WATER SYSTEM

Inlet water is plumbed through a 1/4 turn ball valve, in the front of the dispenser, to a stainless steel tube (imbedded in the insulated tank assembly) where it connects to the copper Water Coil on the

left side of the ice bath tank. The water is chilled to below 40

F and fed through a Vacuum Breaker to a distribution manifold. The manifold has four outlets that extend into the interior of the of the refrigerated compartment. Each outlet connects to a flow meter/solenoid valve which operates the water flow and measures the amount of water that was dispensed.

3.2 CONCENTRATE DELIVERY 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 REFRIGERATION SYSTEM

The copper tube evaporator mounted to the compressor deck and located in the water bath compartment of the insulated tank assembly, forms a ring of ice that weighs approximately 21 pounds. Additional water in the compartment is continuously circulated in the compartment by

the agitator motor to maintain a constant 32

F bath temperature. The copper water coil is mounted

to the dispenser and is located directly below the ice bank.

The insulated tank assembly is substantially fabricated out of aluminum plate. Heat is removed from the concentrate compartment through conduction to the ice bath. Cool air is circulated in the container compartment by a small fan mounted to the back plate of the container compartment.

When product is dispensed, water is drawn through the water coil and chilled. As 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 would not restart immediately when power is re-established. There is a restart delay circuit [approximately five (5) minutes] built into the ice bank control to prevent the compressor from starting under pressure. This feature protects the compressor from premature failure.

The unit has a “lift out” refrigeration deck. The compressor, condenser, fan and agitation motors, evaporator, and ice bank control system are mounted on a common deck plate. The deck is attached to the insulated tank assembly in the back of the unit above the water bath compartment. A removable grill mounted to the top cover provides access to the deck components. The refrigeration deck assembly can also be separated from the unit by first removing the two doors, followed by removing the top cover of the unit. After removing the mounting hardware, the deck can be lifted up and out of the unit.

3.4 ELECTRICAL SYSTEM

ARNING

The unit’s power cord plugs directly into the transformer box located on the front, left corner of the dispenser, behind the splash plate. The transformer box contains the transformers. The transformer supplies 24 VDC power to the CPU (PN 52-2950). A jumper harness from the transformer box connects the supply line power to the compressor deck.

The transformer, compressor, agitator, and condenser fan motor have internal circuit protection. The 24 VDC transformer has a manual reset button located on the side of the transformer.

3.5 ELECTRONIC SYSTEM

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 light and relays membrane switch information to the electronics box. All other functions are controlled by the electronics box located behind the splash plate. Sensors located in the refrigerated product compartment feed status information to the electronics box which continuously monitors dispenser functions.

A. Water Solenoid/Flow Meter

(1) Inlet water is controlled by a combination solenoid valve/flow meter. When the dispense

mode is activated, the solenoid opens and water flows through the water coil, solenoid valve and integral flow meter until it exits at the front of the unit. Each package slot has a stainless nipple that connects to the mixer of the concentrate package when the package is installed.

(2) The flow of water activates the integral digital flow meter which sends a pulse 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. There is a flow control washer in the connecting tube, downstream from the solenoid valve/flow meter that limits the flow rate to 1.5 ounces per second, in case there is excessive water pressure at the installation site.

B. Lighted Front Display

The front door display is illuminated by high intensity LEDs. The printed circuit board is located in the door below the light reflector.

C. 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.
