Viper Installation Manual

!DANGER:

CO2 displaces oxygen. Strict attention MUST be observed in the prevention of CO2 gas leaks in the entire CO2 and soft drink 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 concentrations of CO2 gas experience tremors which are followed rapidly by loss of consciousness and DEATH.

!WARNING:

When installing the unit in or on a counter top, the counter must be able to support a weight in excess of 450 lbs. to insure adequate support for the unit. FAILURE

TO COMPLY COULD RESULT IN SERIOUS INJURY, DEATH OR EQUIPMENT DAMAGE.

Note:

Many units incorporate the use of additional equipment such as icemakers. When any addition equipment is used you must check with the equipment manufacturer to determine the additional weight the counter will need to support to ensure a safe installation.

DISPENSED PRODUCT CONDITIONS

Overrun, as Applied to Carbonated Beverages

Overrun Definition

Overrun is defined as product expansion that takes place in the frozen carbonated drink. It is caused primarily by CO2 gas breakout and secondarily by freezing.

Overrun is a Variable

The percentage or degree of overrun depends on a number of factors. The specific syrup, BRIX, low dispensing volume, carbonation level in the liquid product and freezing of the product. These items all affect overrun. After these factors hav been considered, desired viscosity (product consistency) adjustment may be made on the unit. The viscosity adjustment adjusts product texture from very wet to light.

Specific Product Ingredi-

ents Affect Overrun

Each syrup has its own specific formulation of makeup. Fruit flavors contain citric acids that colas do not. Colas also differ in ingredients from one brand to another.

Publication Number: 621360041TBSER

Viper Installation Manual

Each product formulation has its own peculiarities regarding the way the product absorbs carbonation and the way it releases carbonation.

BRIX Affects Overrun

Sugar in carbonated drinks is like anti-freeze in water. The higher the BRIX, the greater the resistance of the product to freezing. Conversly, in products with lower BRIX, freezing takes place at higher termperatures than for high-BRIX products. Thus, BRIX affects overrun because the amount of sugar in a drink has a direct bearing on the product’s freezing characteristics.

Low Dispensing Volume

Affects Overrun

When a unit sits idle fo a period of time with no drinks being dispensed, CO2 gas in the system takes a “set”. When the first few drinks are drawn off after an idle period, CO2 gas has less tendancy to break out as the drink is dispensed. The result is that these first drinks hav less overrun than drinks dispensed during peakuse periods.

Carbonation Level in Liquid Product Affects Overrun
Freezing Affects Overrun

The higher the specific carbonation level in a given product, the greater the potential for carbonation breakout in frozen carbonated form of that drink. For example, drinks with 3.0 volume of carbonation have more gass breakout in frozen carbonated form and more overrun than drinks that contain 2.0 volumes of CO2 gas.

Freezing causes approximately a 5-7 percent expansion in dispensed frozen carbonated drinks. The degree of freezing is limited because the finished drink is intended to be sipped through a straw. This is not possible if the product is too “solid”.

SYSTEM OVERVIEW

INTRODUCTION

The Viper unit consists of the following systems and hardware:

Multiple freeze barrels, each containing an internal scraper bar driven by an AC motor.

A refrigeration system and an intelligent, hot gas defrost system.

The components are enclosed in a powder-coated steel frame to prevent corrosion. It is covered with ventilated cladding panels and a lighted merchandiser. The cladding is easily removable to facilitate installation, service and maintenance.

Each barrel has a transparent faceplate, with an integral relief valve and a removable, self-closing dispensing valve mounted on the front. A removable drip tray, with cup rest is located directly below the dispensing valves.

A programmable control system with a control panel that controls operational and diagnostic functions and settings is located behind the merchandiser.

An overall schematic of the three delivery systems contained in the unit are shown in Figure 5. The CO2 system is on top, the water system is in the middle and the syrup system is at the bottom of the diagram. The CO2 system interacts with both the water and syrup systems. It provides pressure and carbonation for the syrup/water product mix.

CO2 System

A CO2 tank or bulk CO2 supply delivers carbon dioxide gas (CO2) to an adjustable secondary CO2 regulator assembly that is attached to the tank as shown in Figure 3 and Figure 4. The CO2 system also supplies CO2 to the water boost pump, the expansion tank regulator and the secondary CO2 tank regulators.

CO2 enters the expansion tank regulator and is reduced to approximately 30 psig to feed holding pressure on the expansion tank. This provides a force to work against the barrel pressure when the product freezes and expands.

CO2 also enters the secondary regulators. These regulators are used to adjust barrel overrun/expansion for various products. The pressure settings for various types of syrup are shown in Table 1. Overrun CO2 pressure is applied to the CO2 control solenoids through preset orifices and on to the in-line check valves.

From the in-line check valve, the CO2 flows into the product line.

Water System

Incoming water flows to a water pressure regulator that is preset to 30 psig. It flows through the water booster pump, to the regulator and through a sold-out switch.

Once through the boost pump, the water supply is split to each barrel and is fed to the water flow controls. From the flow rate control, the water passes through a single ball check valve and mixes with the syrup in a wye fitting for injection into the freeze barrel.

Syrup System

Syrup enters the unit through a sold-out switch. It enters a similar flow control to the water system, passes through a single-ball check valve and into the wye fitting where it meets the water for injection into the freeze barrel.

CONTROL PANEL

Introduction

The Viper unit uses a microprocessor based control system that monitors and controls all of the major systems and components of the machine. Temperatures and pressures are monitored, along with pumps, valves and the refrigeration system. They are managed by the control system to provide a consistently high quality product with optimal efficiency.

The control system is set up by the service provider to perform the tasks necessary to keep the Viper unit operating correctly. In addition to controlling the unit, the control system keeps track of the diagnostic information used when adjusting and/or repairing the machine.

The control system needs to be accessed in the following situations:

Installing the Viper

Modifying Operating Characteristics

Checking Performance

Servicing/Repairing the Machine

Checking for Error Messages

The control system is accessed using the control panel located behind the lighted merchandiser. The control panel contains an LCD display and buttons shown in Figure 6.

There are 2 levels of access to the control panel: The first level can be accessed by the operator for normal operation and the second level is used by qualified service technicians for installation and service functions. The service functions can be secured (locked out) so that an operator does not have access to them.

Viper Service Manual

The control panel has a structured organization of menus. The outline of this structure is shown in Figure 7. The Maintenance sub-menu is not visible when the security feature is on.

The first menu that is displayed after the unit is powered up and stabilized is the BARREL STATUS or HOME menu, shown in Figure 6. This menu is displayed when the unit is running in normal operation.

Control Panel Display

The control panel display has two main areas. The first area is the menu display area. This area presents information about the status and settings of the machine. It also displays menus of actions that are taken to modify the functioning of the machine.
