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

SF-1 Dispensing Valve.

(see Figure 6)

NOTE: Make sure the dispensing valve water flow rate is as desired before adjusting the valve for Wa- ter-to-Syrup ‘‘Ratio’’(Brix) of the dispensed product.

Adjust Water-to-Syrup ‘Ratio’of dispensed product by using Ratio Cup (P/N 311100000) and Syrup Diversion Tube Assembly (P/N 319540000) as follows.

1.Remove acorn nut securing the dispensing valve cover, then remove cover from the valve.

2.Install the syrup diversion tube assembly on the dispensing valve by pushing the rubber end of the syrup diversion tube up on the baffle inside the nozzle.

NOTE: Refer to syrup manufacturer’s recommendations on syrup package for Water-to-Syrup ‘‘Ratio’’.

3.Hold container under the dispensing valve. Open the dispensing valve and dispense just enough to fill the syrup diversion tube with syrup.

4.Hold large chamber of the ratio cup under the dispensing valve nozzle. Place free end of the syrup diver- sion tube into syrup chamber marked for proper ratio. Open the dispensing valve and dispense approxi- mately five ounces of water into the ratio cup. Water and syrup levels should be even in the ratio cup.

5.Adjusting Syrup Flow Regulator. If water and syrup levels are not even in ratio cup, turn dispensing valve syrup flow regulator labeled ‘SYRUP’adjusting screw to the left (counterclockwise) no more than 1/4-turn at a time for less syrup or to the right (clockwise) no more than 1/4-turn at a time for more syrup.

6.Repeat Water-to-Syrup ‘Ratio’test and adjust the syrup flow regulator as many times as necessary until proper ratio of the dispensed drink is achieved.

7.Remove syrup diversion tube assembly from the dispensing valve.

8.Install the dispensing valve cover and secure with acorn nut.

UF-1 Dispensing Valve

(see Figure 7)

NOTE: Make sure the dispensing valve water flow rate is as desired before adjusting the valve for Wa- ter-to-Syrup ‘‘Ratio’’(Brix) of the dispensed product.

Adjust Water--to--Syrup “Ratio”(Brix) of the dispensed product by using ratio cup (P/N 311100000) and syrup diversion tube assembly (P/N 319540000) as follows:

1.Remove cover from the dispensing valve by lifting front cover up 1/4 inch and pulling forward.

2.Install syrup diversion tube assembly on the dispensing valve by pushing the rubber end of the syrup diver- sion tube onto the syrup outlet of the inner nozzle.

Notice: Refer to syrup manufacturer’s recommendations on syrup package for water-to-syrup ratio.

3.Dispense enough to fill syrup diversion tube with syrup.

4.Hold large chamber of the ratio cup under the dispensing valve nozzle. Place free end of the syrup diver- sion tube into the syrup chamber marked for the proper ratio. Dispense approximately 6 ounces of water into the ratio cup. Water and syrup levels should be even in cup.

Note: Adjusting screw stops are built into the valve to prevent leakage when the screws are adjusted clockwise too much. Stop adjusting clockwise when turning resistance increases. Turn the screw counterclockwise 1--1/2 turns after the stop are contacted.

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.
