SYSTEM OVERVIEW

The Viper is a Frozen Carbonated Beverage (FCB) unit. It delivers FCB and FUB drinks from a single machine. The unit provides uniform, high quality, high volume product to the customer. The unit is equipped with a patented Intelligent
Defrost TM system for product quality.
The computerized beverage control system provides uniform, high-quality product as well as diagnostic and troubleshooting information for the operator and the service technician.

CONTROL SYSTEM OPERATION

Control System Overview
The Viper uses a control system that monitors and controls all of the major systems and components of the machine. The control system is set up by the service provider to perform the tasks necessary to operate the unit. No additional changes to these settings should be needed. The control system also keeps track of diagnostic information for the machine. The control system is accessed using the control panel located behind the merchandiser. The control panel consists of the LCD display shown in Figure 1.
The control panel has structured menus. The first menu that is displayed after the unit is powered up and stabilized is the BARREL STATUS menu, shown in Figure 4. This menu is also displayed when the unit is operating normally.

Beginning Operation
The control panel is located behind the merchandiser, above the dispensing valves. It is accessed by lifting-up/side-opening the merchandiser. See Figure

When the system is initially powered up, the screens in Figure 2 and Figure 3 are displayed temporarily as the unit goes through self-checks.
If either of these screens remains on, call service.

Basic Operation
If the system check completes normally, the screen shown in Figure 4 is displayed. This is the home screen (Barrel Status). Whenever the system is running in the normal state, the unit displays this screen. The unit powers up in an off condition. To begin normal operation perform the steps in Table 1.

3.| Close the merchandiser.| Close the merchandiser. In approximately 20 minutes or less, product is ready to serve.

While the unit is starting, wash all external surfaces with a mild soap solution and rinse with clean water. Dry all external surfaces with a clean soft cloth. Remove the drip tray (if applicable) and wash with a mild soap solution. Dry the tray thoroughly and replace it. (Do not use abrasive or chlorine based cleaners.)
Dispensed Product Throughput
FCB equipment is designed to provide a high throughput of frozen carbonated product to meet peak draw demands. Where low product throughput is experienced, there is the potential for product quality to diminish. The information shown in Table 2 outlines the minimum throughput per barrel that must be dispensed on a 24 hour basis.

Table 2.

Volume of dispensed product per barrel per 24 hours required to maintain product quality.| 48 oz.| 60 oz

NOTE: Cornelius recommends that, in conditions where the FCB machine is operational and the minimum throughput (as described in Table 2) is not met on a per barrel basis, product should be dispensed and discarded to increase throughput and help assure that product quality is maintained.
NOTE: Data in Table 2 assumes equipment has been correctly installed, commissioned and calibrated as per directions contained in all technical literature published by Cornelius and the recommendations contained in this document have been followed.

Barrel Status Lights
There is a group of three indicator lights above each dispensing valve that indicate the status of the barrel. A description of the three graphic images shown in these indicator is listed in Table 3.

Table 3.

Control Panel Display
The control panel display has two areas. The Menu Display Area presents information about the status and settings of the machine. It also displays menus of actions that are taken to change the functioning of the machine.

Control Panel Menu Buttons

The Menu Buttons Area, which is located across the bottom of the control panel and the arrow buttons to the right is used to operate the unit. There are up to five buttons that are activated on a screen to provide various functions using the control system. Each button that is active has a label directly above it. The label describes what the button controls when pressed or the current menu, if highlighted. Refer to Table 4 for a description of the buttons on the Barrel Status menu.

CO2
CO2 (Carbon Dioxide) Warning

WARNING:
To avoid personnel injury and/or property damage, always secure the CO2 cylinder per local codes.

WARNING

CO2 Displaces Oxygen. Strict Attention must be observed in the prevention of CO2 gas leaks in the entire CO2 and FCB system. If a CO2 gas leak is suspected, particularly in a small area, immediately ventilate the contaminated area before attempting to repair the leak. Personnel exposed to high concentration of CO2 gas experience tremors which are followed rapidly by loss of consciousness and possible death.

Replenishing CO2 Supply
The Viper unit is designed to operate on a CO2 input pressure of 70 to 75 psig. If the installation location has either an independent tank and regulator or a bulk CO2 supply that feeds more than one machine, a shutoff valve and secondary regulator must be placed in the line from the bulk supply to the Viper unit to reduce the CO2 pressure at the unit to 70-75 psig. Perform the procedure in Table 12 to pressurize the CO2 system.
The CO2 supply MUST be changed in accordance with local safety procedures. Maximum CO2 pressure to the Viper unit MUST NEVER EXCEED 75 psi. If pressure exceeds 75 psi, damage to the unit may result. Minimum CO2 pressure to the Viper unit is 70 psig.

WATER
Viper requires a minimum water flow rate of 100 gal. per hr. for a 2 barrel unit. Minimum water pressure is 25 psig. Maximum water pressure to the unit is 100 psig.

Water Filters
Water filters are recommended to insure proper operation of the unit. Refer to local procedures for replacement intervals and service.

Maintaining Product Quality
It has been determined that there are three main factors that affect the rate at which product quality diminishes, as indicated by a change in product appearance. These factors are:

1. Dispensed Product Throughput
2. Programmed Defrost Scheduling
3. Viscosity Setting

It is recommended that the following instructions be read and followed relative to operating and establishing settings on the Viper equipment. Anyone who has not been trained to service this equipment should not attempt to modify equipment settings. Contact an authorized service provider.
The following instructions are generic in nature. Your actual water system may vary according to your situation. Please follow any specific instructions for your location.

Intelligent Defrost TM System
The control system in the Viper unit includes a function to automatically defrost product in the cylinder when product throughput is not sufficient to maintain quality. It also allows the service provider to set defrost lockouts during busy times during the day.

Sleep Mode Recommendations
Sleep Mode is recommended when the unit will not have any usage for a period of time over 3 hours. This increases the life of the machine and reduces energy consumption.
A wake time must be programmed to return the unit to normal operation. It is recommended that the unit be programmed
to wake up approximately 20 minutes before product is needed. For ambient temperature higher than 75oF, the times may increase as the ambient temperatures increases.

Viscosity Setting
The lowest possible viscosity settings are recommended to achieve desired drink quality. In most typical installations, using sugar-based syrup allows the viscosity to be set slightly higher. Diet syrups freeze much more readily than sugar based syrups, so the viscosity should be set lower for diet products.
This increased viscosity is achieved by freezing the product in the cylinder to a lower temperature, thereby increasing ice crystal size and growth. As the ice crystal size increases, there is a potential for product quality to diminish.

PREVENTATIVE MAINTENANCE

SUMMARY
There are no daily maintenance procedures required on the Viper unit other than normal cleanup of spills or overspray and emptying the drip tray. Normal equipment maintenance intervals are listed in Table 8 It is recommended that a preventa-tive maintenance procedure be performed every twelve (12) months. This procedure should include all of the maintenance items described in Table 8 and the following sections.
