GENERAL INFORMATION

IMPORTANT: To the user of this manual - This manual is a guide for installing, operating, and maintaining this equipment. Refer to Table of Contents for page location of information pertaining to questions that arise during installation, operation, service and maintenance, or troubleshooting this equipment.

GENERAL DESCRIPTION

This section gives the description, theory of operation, and design data for the FCB Solid-State Post-Mix Two-Flavor Dispenser with Hot-Gas Defrost (hereafter referred to as a Unit).

UNIT DESCRIPTION

The Unit (see Figure NO TAG) consists basically of two freeze cylinders each containing an internal beater driven by an electric motor, one refrigeration system with a 2-horsepower compressor, one carbonator which feeds both carbonator-blender tanks, a timer-controlled automatic hot-gas defrost system to defrost the freeze cylinders, and interconnecting tubing, components, and fittings necessary to regulate, transfer, and dispense product. The components are attached to a steel frame and are enclosed in a steel cabinet. The cabinet panels are easily removed to facilitate installation and service and maintenance. A transparent faceplate, with an integral relief valve and a removable self-closing dispensing valve, is mounted on front of each freeze cylinder. A removable drip tray, with cup rest, is located directly below the dispensing valves.

CAUTION: Before shipping, storing, or relocating Unit, syrup systems must be sanitized and all sanitizing solution must be purged from syrup systems. All water must also be

purged from plain and carbonated water systems. A freezing ambient environment will cause residual sanitizing solution or water remaining inside Unit to freeze resulting in damage to internal components.

THEORY OF OPERATION

(see Figure 2)

IMPORTANT: Before connecting electrical power to Unit, refer to nameplate and note if Unit is to be operated with 50 or 60 Hz power source and also note beaters drive motors manufacturer’s name. No. 6, No. 7, and No. 8 switches on DIP switch assembly on master circuit board must be set according to motors manufacturer and for 50 or 60 Hz operation.

A CO2 cylinder delivers carbon dioxide (CO2) gas to an adjustable primary CO2 regulator assembly attached to the cylinder. Primary CO2 regulator assembly in turn delivers CO2 gas to adjustable secondary CO2 regulators inside the Unit and also to two soft drink tanks. CO2 is delivered from adjustable secondary CO2 regulators to carbonator tank and also two product-blender tanks inside the Unit. CO2 gas pressure pushes syrup out of soft drink tanks, through syrup sold-out float switches, through electrically-operated syrup solenoid valves, through adjustable syrup flow regulators, and on to product blender tanks. At the same time, plain water passes through water pressure regulator and is pumped into carbonator tank by water pump and is carbonated by CO2 gas pressure also entering tank. Carbonated water is pushed by CO2 gas pressure from carbonator tank, through electrically operated carbonated water solenoid valves through adjustable carbonated water flow regulators, and on to product blender tanks. Carbonated water and syrup enter tanks properly proportioned (blended) for desired BRIX of dispensed product by adjustment of syrup flow regulators. From product blender tanks, product is pushed by CO2 gas into freeze cylinders. The beater in each freeze cylinder is driven by an electric motor. Scraper blades, attached to beaters, scrapes product from cylinder walls as product enters freeze cylinders and is frozen. Transparent faceplate, attached to front of each freeze cylinder, includes a self-closing dispensing valve and a spring-loaded relief valve that protects freeze cylinder from accidental over pressure. The relief valve is also used to bleed CO2 gas pressure from freeze cylinder to atmosphere when filling cylinder with product. Electronic sensing on each freeze cylinder motor provides a means of adjusting viscosity (consistency) of dispensed product to suit customer preference.

DEFROST SYSTEMS

The Unit is equipped with both manual and automatic hot-gas defrost systems. The automatic defrost system may be programmed into Unit to occur up to nine different times a day with a minimum of two hours between defrost time settings or the system may be completely turned off.

326142000 2

MANUAL DEFROST SYSTEM

The Manual hot-gas defrost system may be activated at any time by pressing ‘‘DEFROST’’ switch on front of Unit. Refrigeration compressor will operate for a short time, then both freeze cylinders will go into defrost and defrost for approximately 60-seconds. At end of manual defrost cycle, Unit will return to normal operation. Manual defrost may be cancelled at any time by pressing ‘‘CANCEL DEFROST’’ switch.

AUTOMATIC DEFROST SYSTEM

The automatic hot-gas defrost system may be programmed into Unit to occur up to nine different times a day with a minimum of two hours between defrost settings. At start of each automatic defrost cycle, refrigeration compressor will operate for 30-seconds to pump freon out of freeze cylinders evaporator coils. After freon has been pumped out of freeze cylinders evaporator coils, No. 1 freeze cylinders only will go into defrost cycle and defrost for approximately 7-minutes, then will return to normal operation. This ends automatic defrost cycle of No. 1 freeze cylinder. No. 2 freeze cylinder will defrost 30-minutes after the start of No. 1 freeze cylinder. The next automatic defrost cycle will occur according to time programmed into the Unit. Automatic defrost may be cancelled at any time by pressing ‘‘CANCEL DEFROST’’ switch.

‘‘SLEEP’’ (SLEEP TIME)

‘‘SLEEP’’ ((SLEEP TIME) may be programmed into Unit to allow Unit to go into sleep time (Unit shut down, freeze cylinders beaters and refrigeration systems not operating). At start of sleep time, refrigeration compressor will operate for 30-seconds to pump freon out of freeze cylinders evaporator coils, then No. 1 freeze cylinder will go into defrost and defrost for 60-seconds. After No. 1 freeze cylinder has defrosted,, No. 2 freeze cylinder will go into defrost and defrost for 60-seconds. At end of No. 2 freeze cylinder defrost, Unit will shut down and go into sleep time.

‘‘WAKE UP’’ (WAKE UP TIME)

‘‘WAKE UP’’ (WAKE UP TIME) may be programmed into the Unit to allow Unit to resume normal operation at a desired time. When programmed wake up time is reached, an alarm will sound for a short duration, then Unit will resume normal operation.

NOTE: Automatic defrost, sleep time, and wake up time may be used in any combination together or separately.
