Cornelius R-134A service manual Purge Water OUT of Syrup Systems Restore Operation

Page 36

Place all bag-in-box syrup containers syrup outlet tubes in container containing potable water.

20.Flush sanitizing solution from the syrup system and the dispensing valve as follows:

A.Place waste container under applicable dispensing valve.

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

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.

21.Repeat steps 19 and 20 preceding to purge sanitizing solution out of the remaining syrup systems and dispensing valves.

22.Remove potable water source from the syrup system.

STEP 5. PURGE WATER OUT OF SYRUP SYSTEMS (RESTORE OPERATION)

23.Syrup Tank Systems.

A.Noting syrup tanks CO2 regulator pressure setting observed in step 4 preceding, readjust CO2 regula- tor to the observed pressure setting,

B.Connect tanks containing syrup into syrup systems.

Bag-in-Box Syrup System.

C.Remove all bag valves from bag-in-box syrup containers outlet tubes connectors.

D.Connect bag-in-box syrup containers into the syrup systems.

24.Place waste container under dispensing valves. Dispense from all dispensing valves to permit syrup to purge all potable water from the syrup systems and the dispensing valves. Continue to dispense from the dispensing valves until only syrup is dispensed from the syrup systems and valves.

WARNING: To avoid possible personal injury or property damage, do not attempt to remove the syrup tank cover until CO2 pressure has been released from the tank.

25.Dispose of waste sanitizing solution in a sanitary sewer, not in a storm drain, then thoroughly rinse the in- side and the outside of the container that was used for sanitizing solution to remove all sanitizing solution residue.

CARBONATOR WATER PUMP YEARLY MAINTENANCE OR AFTER WATER SYSTEM DISRUPTIONS

WARNING: The carbonator water pump water inlet strainer screen and the double-liquid check valve must be inspected and cleaned at least once a year under normal circumstances, and after any disruptions (plumbing work, earthquake, etc.) to the water

supply system that might cause turbulent (erratic) flow of water through the system. A carbonator water pump with no screen or a defective screen in the strainer would allow foreign particles to foul the double-liquid check valve. CO2 gas could then back flow into the water system and create a health hazard.

The carbonator water pump water inlet strainer screen and the double-liquid check valve must be inspected and cleaned at least once a year under normal circumstances and after any water system disruption (plumbing work, earthquake, etc.) as follows:

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.
