1. Close empty CO2 cylinder shutoff valve, then remove empty cylinder.

WARNING: To avoid personal injury and/or property damage, always secure CO2 cylinder in an upright position with a safety chain to prevent it from falling over. Should the valve become accidentally damaged or broken off, CO2 cylinder can cause personal injury.

2.Install full CO2 cylinder, the open shutoff valve. MAKE SURE CO2 CYLINDER IS POSITIONED IN UP-

RIGHT POSITION AND IS FASTENED WITH A SAFETY CHAIN.

REPLENISHING SYRUP SUPPLY

1.Remove CO2 and syrup quick disconnects from empty syrup tank, then remove tank.

2.Place full syrup tank in position, then connect CO2 and syrup quick disconnects to tank.

PERIODIC CLEANING OF COOLING UNIT

Periodically wash all external surfaces of the Cooling Unit, rinse with clean water, then wipe the Cooling Unit dry with a clean soft cloth. DO NOT USE ABRASIVE CLEANERS.

CLEANING AND SANITIZING

DAILY CLEANING OF UNIT

1.Remove cup rest from the drip tray.

2.Wash drip tray in place on the Unit, then rinse drip tray with hot water allowing water to drain out through the drain hose.

3.Wash cup rest, then rinse the cup rest with clean water. Install cup rest in the drip tray.

4.Clean all external surfaces of the Unit with a sponge. Rinse out the sponge with clean water, then wring excess water out of the sponge and wipe off all external surfaces on the Unit. Wipe Unit dry with a clean soft cloth. DO NOT USE ABRASIVE CLEANERS.

5.Remove nozzle and syrup diffusers from the dispensing valves. Place nozzles and syrup diffusers in sani- tizing solution.

6.Wash the nozzles and syrup diffusers in sanitizing solution, then rinse them with potable water.

7.Re-install nozzles and syrup diffusers back on the dispensing valves.

SANITIZING POST-MIX SYRUP SYSTEMS

IMPORTANT: Only qualified Service Personnel should perform sanitizing procedure on the post-mix syrup systems.

The post-mix syrup systems should be sanitized every 90-days using a non-scented household liquid bleach containing a 5.25 % sodium hypochlorite concentration. Proceed as follows to sanitize the post-mix syrup sys- tems.

1.Disconnect syrup supplies from syrup systems.

2.Rinse quick disconnects (syrup tanks systems) or bag-in-box connectors (syrup bag-in-box systems) in warm potable water.

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.
