DESCRIPTION
IMPORTANT: To the user of this manual - This manual is a guide for installing, operating, and
maintaining this equipment. Refer to the Table of Contents for page location for detailed information
pertaining to questions that arise during installation, operation, service, or maintenance of this
equipment.
CAUTION: Before shipping, storing, or relocating this Unit, the syrup systems must be
sanitized and all sanitizing solution must be purged from the syrup systems. All water must
also be purged from the plain and carbonated water systems. A freezing ambient
environment will cause residual water in the Unit to freeze resulting in damage to internal
components.
WARNING: CO2displaces oxygen. Strict attention must be observed in the prevention of
CO2(carbon dioxide) gas leaks in the entire CO2and soft drink system. If a CO2gas leak is
suspected, particularly in a small area, immediately ventilate the contaminated area before
attempting to repair the leak. Personnel exposed to high concentration of CO2gas will experience
tremors which are followed rapidly by loss of consciousness and suffocation.
The Sentry III-A Post--Mix Cooling Unit with R-134A Refrigerant (see Figure 1) is designed to provide cooled
syrup, carbonated water, and plain water to the dispensing station(s) connected to the cooling unit through an
insulated python (length as ordered).
The lower cabinet of the Cooling Unit consist of carbonated water, plain water, and syrup coils located in the
water tank, a carbonator, and a carbonated water circulating pump. The Cooling Unit utilizes a drop--in refrigeration assembly which contains the refrigeration compressor and a condenser coil and fan assembly as shown in
Figure 3
An optional Cooling Unit Stand (P/N 309802069) is available to elevate the Cooling Unit up off the floor.

FIGURE 1. SENTRY III-A COOLING UNIT
THEORY OF OPERATION
(see Figure 2)
A CO2cylinder delivers carbon dioxide gas (CO2) through adjustable CO2regulators to the soft drink tanks and
also to the built--in carbonator located inside the Cooling Unit. Plain water is pumped into the carbonated water
tank by the water pump and is carbonated by regulated CO2pressure also entering the tank. When dispensing
valve is opened, CO2pressure exerted upon the syrup in the soft drink tank pushes syrup from the tank,
through the Cooling Unit cooling coils, through the python and on to the dispensing valve. Carbonated water is
pushed by CO2pressure from the carbonated water tank, through the Cooling Unit cooling coils, through the
python and on to the dispensing valve. Syrup and carbonated water meet at the dispensing valve resulting in a
carbonated drink being dispensed. Plain water is also available at the dispensing station by passing through the
Cooling Unit cooling coils, through the python, and on to the dispensing station. Carbonated water is replenished when carbonated water level inside the carbonator tank drops to a specified level which in turn automatically starts the carbonator water pump motor. When carbonated water level inside the carbonated water tank
has been replenished, carbonator water pump motor will stop. Carbonated water is continuously being circulated from the Cooling Unit, out through the insulated python to the dispensing station(s), and back to the cooling unit which maintains liquids in the python at a cold temperature.
