Introduction

Incoming water flows to a water pressure regulator that is preset to 30 psig. It
flows through the water booster pump, to the regulator and through a sold-out
switch.
Once through the boost pump, the water supply is split to each barrel and is fed to
the water flow controls. From the flow rate control, the water passes through a
single ball check valve and mixes with the syrup in a wye fitting for injection into
the freeze barrel.
Syrup enters the unit through a sold-out switch. It enters a similar flow control to
the water system, passes through a single-ball check valve and into the wye fitting
where it meets the water for injection into the freeze barrel.
The Viper unit uses a microprocessor based control system that monitors and
controls all of the major systems and components of the machine. Temperatures
and pressures are monitored, along with pumps, valves and the refrigeration
system. They are managed by the control system to provide a consistently high
quality product with optimal efficiency.
The control system is set up by the service provider to perform the tasks
necessary to keep the Viper unit operating correctly. In addition to controlling the
unit, the control system keeps track of the diagnostic information used when
adjusting and/or repairing the machine.
The control system needs to be accessed in the following situations:
• Installing the Viper
• Modifying Operating Characteristics
• Checking Performance
• Servicing/Repairing the Machine
• Checking for Error Messages
The control system is accessed using the control panel located behind the lighted
merchandiser. The control panel contains an LCD display and buttons shown in
Figure 12.
There are 2 levels of access to the control panel: The first level can be accessed
by the operator for normal operation and the second level is used by qualified
