SYSTEM OVERVIEW

NTRODUCTION
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.
