SYSTEM OVERVIEW

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 cladding is easily removable to facilitate installation, service and

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.

configuration for the Viper refrigeration system.
