INTRODUCTION

SYSTEM OVERVIEW

Introduction

The Viper system is a state-of-the-art FCB/FUB machine. Viper provides improved drink availability, reliability and reduced
complexity in a compact, reduced footprint machine.

Viper provides the highest quality in drink appearance and consistency while keeping operation and maintenance simple and
straightforward.

The unit consists of multiple freeze barrels that each contain an internal beater driven by an electric motor, a refrigeration
system, a timer-controlled, intelligent defrost system and interconnecting tubing and controls required to dispense the product.

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 have
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 Ingredients 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. 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. Conversely, in products with lower BRIX, freezing takes place at higher temperatures 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.

Figure 1.

Low Dispensing Volume Affects Overrun

When a unit sits idle for 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 tendency to break out as the drink is dispensed. The result is
that these first drinks have less overrun than drinks dispensed during peak-use periods.

Carbonation Level in Liquid Product 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 gas breakout in frozen
carbonated form and more overrun than drinks that contain 2.0 volumes of CO

2 gas.

Freezing Affects Overrun

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”.

6. Inspect the dispenser cabinet and make sure it has no scratches, dents or any other cosmetic defects.

7. Make sure that the glass or plastic merchandiser panels are not scratched or cracked.

8. Open the packages of loose parts and inspect all of the parts for damage or missing parts. Check the
parts received against the packing list to insure receipt of all parts.

NOTE: If unit is installed more than three months from date of production, replace the seals according to

the instructions accompanying the spare seals supplied with the unit. Unite date of manufacture
is included in the unit serial no. as follows: The date code follows the first letter of the serial
number. The next four numbers reflect the date of manufacture. The first two represent the year,
the next two the week. For example, 62A0815xxxxxx would be a unit produced during the 15th
week of 2008.

COUNTER LOCATION

Select a location in a well ventilated area, close to a grounded electrical outlet and backroom connections. The counter must
be capable of supporting a minimum of 400 pounds. If possible do not place the unit close to hot and/or steaming machines.

The minimum clearance is: 2 in. (5.08 am) in back and 12 in. (30.48 am) on top of the unit. If both sides have a minimum
clearance of 2” (5.08 am), then the unit may be flush to the wall in the back.

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by
a person responsible for their safety.

Children should be supervised to ensure that they do not play with the unit.

NOTE: Condenser air is drawn in from the sides or back and discharged out the top. Failure to maintain

clearance space will reduce the capacity of the unit and cause premature compressor failure.

INSTALLING LEG

NOTE: : Before installing legs, the plastic plugs must be removed.

Unpack the four (4) legs and install them into the threaded holes provided in the bottom of the unit. The installer must provide
flexibility in the product and utility supply lines to permit shifting the position of the dispenser sufficiently to clean the area
beneath it.

COUNTER MOUNTING

The Viper unit must be sealed to the counter. The MOUNTING TEMPLATE (Figure 2) indicates where openings can be cut in
the counter. Locate the desired position for the dispenser, then mark the outline dimensions on the counter using the
MOUNTING TEMPLATE. Cut openings in the counter.

Apply a continuous bead of National Sanitation Foundation (NSF) listed silastic sealant (Dow 732 or equal) approximately 1/4”
inside of the unit outline dimensions and around all openings. Then, position the unit on the counter within the outline
dimensions. All excess sealant must be wiped away immediately.

The beverage tubes, drain tube and power cord are routed through the large opening in the bottom of the unit. See
th

e MOUNTING TEMPLATE (see Figure 2), for locating the re

quired clearance hole in the counter for these utility

lines.

BACKROOM REQUIREMENTS

Typically the supplies for the unit are located in a backroom adjoining the service area. Syrup, water and CO2 lines are then
run from the backroom to the service area. The backroom supplies (syrup boxes, CO2, water filters and pumps) are typically
installed on a rack system that sits on the floor, as shown in Figure 3.The CO2 cylinder is normally mounted against the wall.

.

SUPPLY CONNECTIONS

All of the electrical and supply connections to the unit are typically located near the bottom rear of the unit. There are alternate
locations for the electrical and supply connections on the bottom of the unit, below the rear locations. The bottom connection
locations may be used if the unit is located directly against a wall.

The electrical connection is located at the
shown in Figure 4.
