3.Using a clean syrup tank (syrup tank system) or a five-gallon container (bag-in-box system), prepare a full tank or container of liquid dishwasher detergent by using 70_F (21_C) to 100_F (38_C) potable water and 0.5 oz. (15 ml) of liquid dishwasher detergent to one gallon of potable water. Stir detergent solution to thoroughly mix the solution.

4.Syrup Tank Systems.

A.Observe and note CO2 pressure setting on the syrup tanks CO2 regulator, then re-adjust CO2 regula- tor to 60 to 80-psi. Pressurize syrup tank containing detergent solution to 60 to 80-psi.

B.Connect detergent solution tank, pressurized at 60 to 80-psi, into one of the syrup systems.

Bag-in Box Syrup Systems.

C.Install bag valves, cut from empty bag-in-box syrup containers, on ends of syrup containers syrup outlet tubes connectors.

D.Place all syrup outlet tubes, with bag valves on their ends, in container containing detergent solution.

5.Flush the syrup system and dispensing valve as follows:

A.Place waste container under applicable dispensing valve.

B.Activate the dispensing valve for one minute to purge all syrup and flush out the syrup system.

C.Continue to activate the dispensing valve in cycles (“ON”for 15-seconds, “OFF”, then “ON”for 15-seconds). Repeat “ON”and “OFF”cycles for 15-cycles.

6.Connect detergent solution to the remaining syrup systems and flush syrup out of the syrup systems as instructed in step 5 preceding.

7.Remove detergent solution source from the syrup system.

STEP 2. FLUSH SYRUP SYSTEMS

8.Syrup Tank Systems.

Connect syrup tank containing potable water, pressurized at 60 to 80-psi, into one of the syrup systems.

Bag-in-Box Syrup System.

Fill five-gallon container with potable water, then place all bag-in-box syrup containers syrup outlet tubes in container containing potable water.

9.Flush detergent solution out of the syrup system and dispensing valve as follows:

A.Place waste container under applicable dispensing valve.

B.Activate the dispensing valve for one minute to purge all detergent solution and flush out the syrup system.

C.Continue to activate the dispensing valve in cycles (“ON”for 15-seconds, “OFF”, then “ON”for 15-seconds). Repeat “ON”and “OFF”cycles for 15-cycles.

10.Connect potable water source to the remaining syrup systems and flush detergent solution out of the syrup systems as instructed in step 9 preceding.

11.Remove potable water source from the syrup system.

STEP 3. SANITIZE SYRUP SYSTEMS

12.Using a clean syrup tank (syrup tanks system) or a five-gallon container (bag-in-box system), prepare sani- tizing solution using 70_F (21_C) to100_F (38_C) potable water and 0.5 oz. (15 ml) of non-scented household liquid bleach that contains a 5.25 % sodium hypochlorite concentration to one gallon of potable water. This mixture must not exceed 200 PPM of chlorine. Stir sanitizing solution to thoroughly mix.

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.
