3.Open the plain water inlet supply line shutoff valve. Check for water leaks and tighten any loose connections.

4.Place the carbonator water pump motor power switch (located on the refrigeration assembly control box) in the “ON”position. The carbonator water pump will start and continue to operate until the carbonated water

tank has been filled, then the water pump motor will stop. Check for CO2, plain water, and carbonated wa- ter leaks and tighten any loose connections.

5.Adjust the syrup tanks CO2 regulators as instructed in SERVICE AND MAINTENANCE section of this manual.

6.Install full syrup tanks into the syrup systems.

7.Make sure keyed lock-out switch (left-side facing front of Unit) is in the “ON”(vertical) position.

8.Dispense from each dispensing valve until air is bled from the systems and until syrup and applicable plain or carbonated water are dispensed.

9.Check for syrup and water leaks and repair any leaks.

10. Install the Unit hood and secure with screw.

ADJUST WATER-TO-SYRUP “RATIO” (BRIX) OF DISPENSED PRODUCT

1.Adjust the dispensing valves for water flow rate as instructed in SERVICE AND MAINTENANCE section of this manual.

2.Adjust the dispensing valves for Water-to-Syrup “Ratio”(Brix) of dispensed product as instructed in SERVICE AND MAINTENANCE section of this manual.

3.Seal all access holes to the Unit with a silastic sealant such as Dow Corning RTV 731 or equivalent.

4.Install Unit front access panel and secure with two screws.

5.Install drip tray on the Unit.

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.
