INTRODUCTION
SYSTEM OVERVIEW
Introduction
The Frutista Viper system is a state-of-the-art FCB/FUB machine. The Frutista Viper machine 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, CO2gas in the system takes a “set”.
When the first few drinks are drawn off after an idle period, CO2gas 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 CO2gas.
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”.

INSTALLATION
DELIVERY, INSPECTION & UNPACKING
NOTE: Cornelius is not responsible for damaged freight. If damage is found, you must save all
packaging material and contact the freight carrier. Failure to contact the carrier within 48
hours of receipt may void your claim.
1. Inspect the carton and note any damage, regardless if it appears minor. If the carton is damaged,
note on the consignee copy of the freight invoice “exterior carton damage – concealed damage
possible” and contact the freight company immediately.
2. Remove any staples along the bottom edge of the carton and lift the carton off the pallet.
3. Remove the exterior carton sleeve, internal fillers and plastic bag around the unit. Carefully inspect
the unit for damage.
4. Remove the bolts holding the dispenser to the pallet.
5. Remove the packing fillers from the top of the unit.
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 cm) in back and 12 in. (30.48 cm) on top of the unit. If both sides have a
minimum clearance of 2” (5.08 cm), then the unit may be flush to the wall in the back.
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.
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 2. The CO2cylinder
is normally mounted against the wall.

Figure 2.
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 left side of the rear panel and the tubing supplies are located on the
right side, as shown in Figure 3.

Water Supply Requirements
NOTE: Water connections require 1/2” I.D. tubing. All hoses must reach the back of the unit plus
an adequate amount of extra tubing to allow the unit to be pulled out for servicing.
The Viper unit is designed as a high throughput unit. It is very important that the incoming water line is dedicated
to the unit. This line should not have any other machines connected which could cause a water surge, such as
coffee makers or ice machines.
!
IMPORTANT:
The water supply should be consistent with proper water quality standards (neutral pH of 7.0 to 8.0), and should
not be connected to a water softener. Drink quality may be affected by poor water conditions. Water connections
should be sized, installed and maintained according to federal, state and local laws.
NOTE: Size, install, and maintain the water pipe, connections, and fixtures directly connected to
a potable water supply in accordance with Federal, State, and Local codes. It is the
installer’s responsibility to ensure that the potable water supply is equipped with
protection against backflow. This protection can be an air gap as defined by ANSI/ASME
A112.1.2-1979 or by an approved vacuum breaker or other approved method. If the
flowing water pressure at the back of the unit is less than the specified 25 psi and 100
GPH flowrate (per 2 barrels) a water pressure booster is required. It is recommended that
a water shutoff valve and water filter be installed in the water supply line.
Water Connections
Use the appropriate fittings and clamps to connect the water line to the unit. Run the tubing for the water (1/2 in.
ID, Min.) from the water source in the backroom to the unit and make all appropriate connections. Do not turn on
the water supply to the unit.
CO2Requirements
!
WARNING:
CO2displaces oxygen. Persons exposed to high concentrations of CO2will experience tremors, followed by loss
of consciousness and death. It is very important to prevent CO2leaks, especially in small unventilated areas. If a
CO2leak occurs ventilate the area before fixing the leak.
NOTE: There are two CO2delivery systems available: 
• High pressure Cylinder requires a Primary Regulator with a minimum inlet pressure of
500 psi.
• Low Pressure Bulk System requires a Secondary Regulator with a Maximum inlet
pressure of 200 psi.
NOTE: CO2connections require 3/8” I.D. tubing. All hoses must reach the back of the unit plus an
adequate amount of extra tubing to allow the unit to be pulled out for servicing.
NOTE: Two secondary regulators are required after the CO2supply. The dedicated secondary
regulator adjusted to 75 +/- 1 psig to supply the unit. It is highly recommended that this be
within 10 ft. of the unit and that the CO2source is not shared.
CO2Connections
Use a source-dedicated secondary regulator, fittings and clamps to connect the CO2line to the unit, as shown in
Figure 5. Set the regulator for 75 +/- 1 psig at the unit. Run the tubing for the CO2from the secondary regulator to
the unit and make all appropriate connections. Ideally, locate the regulator within 3 ft. of the unit. Another
secondary regulator is to be used to supply the Bag in Box pumps. It is to be set to 75 psig, not lower. Do not turn
on the CO2supply to the unit.

Syrup Requirements
NOTE: Syrup connections require 3/8” I.D. tubing. All hoses must reach the back of the unit plus
an adequate amount of extra tubing to allow the unit to be pulled out for servicing.
Syrup Connections
Use the appropriate fittings and clamps to connect the syrup line to the unit. Run the tubing for the syrup (3/8 in.
ID, Min.) from the backroom to the unit and make all appropriate connections. Do not turn on the syrup supply to
the unit.
