GENERAL INFORMATION

IMPORTANT: To the user of this manual - This manual is a guide for installing, operating, and main- taining this equipment. Refer to the Table of Contents for page location for detailed information per- taining to questions that arise during installation, operation, service, or maintenance of this equipment.

GENERAL DESCRIPTION

This section gives the Unit description, theory of operation, and design data for the five and six-flavor Ventures Post-Mix Dispensers with Built-In Cold Carbonators (hereafter referred to as Units).

This Unit must be installed and serviced by a qualified Service Person. This Unit contains no User serviceable parts.

UNIT DESCRIPTION

The Units are compact with high-impact and corrosion-resistant moulded lower housings and may be island- mounted or installed on a front or rear counter. Their refrigeration assemblies are the 1/3 H.P. drop-in type that can be easily removed for service and maintenance. The Units are equipped with built-in cold carbonators with their carbonated water tanks located inside the Units lower housings water tanks. Adjustable syrup flow regulators, located on the electrically operated dispensing valves, are easily accessible to control water-to-syrup “Ratio”of the dispensed product.

Installation of the Unit on a countertop, installation of LOOSE-SHIPPED PARTS, connection of plain water and syrup supplies, adjustment of CO2 regulators, filling water tank with water, and plugging the Unit power cord into an electrical outlet is all that is required for operation.

NOTE: Optional 4-inch Legs (P/N 314744000) that will elevate the Unit 4-inches above the countertop are available. When ordering legs, order a quantity of four.

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.

R-134A specifications

Cornelius R-134A is a refrigerant commonly used in various cooling and air conditioning applications. It belongs to the hydrofluorocarbon (HFC) family and has become a favored alternative to many ozone-depleting substances. Unlike its predecessors, R-12, which has been phased out due to its detrimental effects on the ozone layer, R-134A offers a more environmentally friendly solution, albeit still having global warming potential.

One of the main features of R-134A is its favorable thermodynamic properties. It exhibits a low boiling point of approximately -26.3°C (-15.3°F), making it suitable for various refrigeration applications, including automotive air conditioning, commercial cooling systems, and domestic refrigerators. Its efficiency is regarded as superior, allowing for quick heat absorption and dissipation. This efficiency translates into energy savings, ultimately benefiting both consumers and manufacturers.

R-134A also boasts a relatively high vaporization heat, demonstrating its effectiveness in heat transfer processes. The low toxicity and non-flammability of R-134A further enhance its appeal, as it poses minimal risk during handling and application. This characteristic makes R-134A safer for technicians and users compared to older refrigerants, which presented higher health hazards.

Within modern technologies, R-134A plays a crucial role in both chiller systems and heat pump applications. It is compatible with various lubricants, allowing manufacturers to utilize R-134A in existing systems with minimal modifications. However, it is essential to use the correct type of oil, as mixing different types can lead to system inefficiencies and potential failure.

Despite its advantages, R-134A has a global warming potential of around 1,430 times greater than carbon dioxide, prompting the refrigerant industry to look for alternatives. Newer refrigerants, such as R-1234yf, offer lower environmental impact, driving a shift towards more sustainable options.

In conclusion, Cornelius R-134A remains a widely used refrigerant known for its efficiency, safety, and effectiveness in heat transfer. While it has played a significant role in the refrigeration and air conditioning industries, the ongoing search for eco-friendly alternatives highlights the need for continued innovation and adherence to environmental standards.
