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 CO
secondary regulator must be placed in the line from the bulk supply to the Viper unit to reduce the CO
the unit to 75 +/- 1 psig.
The CO2 supply MUST be changed in accordance with local safety procedures. Maximum CO2 pressure to the
Viper unit MUST NEVER EXCEED 80 psi. If pressure exceeds 80 psi, damage to the unit may result. Minimum
CO

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 TM 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 TM product in the cylinder when
product throughput is not sufficient to maintain quality. It also allows the service provider to set defrost
during busy times during the day.
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 wakeup approximately 20 minutes before product is needed. For ambient temperature higher than
o
F, the times may increase as the ambient temperatures increases.
75
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.
Maintenance is important to the quality of the product being served. The following sections outline the minimum
requirements for periodic maintenance of the unit and the surrounding service area.
NOTE: Do not use abrasive cleaners on the unit.
Only trained and qualified persons should perform these cleaning procedures.
DAILY MAINTENANCE
On a daily basis, clean 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 chlorine based solutions on stainless steel surfaces.
MONTHLY MAINTENANCE
CLEANING AIR FILTER
The air filter should be cleaned at least once a month (more often in harsh environments). Perform the procedure in
Table 8. to clean the air cleaner.
