10.Syrup Tank Syrup System.

Disconnect syrup tank containing syrup from No. 1 syrup system. Bag-in-Box Syrup System.

A.Disconnect No. 1 syrup pump syrup inlet line from bag-in-box containing syrup.

B.Cut connector from empty bag-in-box container, then connect connector to No. 1 syrup pump syrup inlet line.

NOTE: Sanitizing solution is used in a more concentrated form because it will be diluted approximately four-to-one in the product blender tank. If a powder type sanitizer is to be used, it must be thoroughly dissolved with water prior to adding to a sanitizing solution container.

11.Using a clean syrup tank (syrup tank system) or a clean 5-gallon pail (bag-in-box system), prepare a full

tank or pail of sanitizing solution using Chlor-Tergent (Oakite Product, Inc.) or equivalent sanitizer. Mix san- itizing solution by using 70° F to 100° F (max) plain water and 2.65 oz./gallon sanitizer. This mixture will provide 800-ppm of chlorine. Sanitizing solution will be diluted to approximately 200-ppm inside the product blender tank after carbonated water has been mixed with the sanitizing solution.

12.Syrup Tank System.

Shake sanitizing solution tank thoroughly to mix the solution, then connect tank to the No. 1 syrup system. Bag-in-Box Syrup System.

Mix pail of sanitizing solution thoroughly, then immerse end of No. 1 syrup pump syrup inlet line into pail of sanitizing solution.

13.Press SIDE 1 ‘‘SYRUP PRIME’’ switch to fill No. 1 syrup system syrup float switch with syrup.

14.Press SIDE 1 ‘‘BLEND ON/OFF’’ switch to fill No. 1 product blender tank with sanitizing solution. The car- bonator water pump will start and begin pumping carbonated water into the product blender tank which will dilute sanitizing solution also entering the tank.

15.After carbonator water pump cycles off, completely fill No. 1 freeze cylinder with sanitizing solution by re- peatedly pulling and releasing the relief valve knob on the freeze cylinder faceplate and until sanitizing solu- tion comes out of the relief valve port. Open the dispensing valve until sanitizing solution flows from the valve, then close the valve. Open the product blender tank sample valve until sanitizing solution flows from the valve, then close the valve.

16.Press SIDE 1 ‘‘MOTOR’’ switch to start No. 1 freeze cylinder beater. Allow sanitizing solution to remain in the freeze cylinder for no less than 10 and no more than 15 minutes (max) contact time.

17.When sanitizing solution contact time has elapsed, press SIDE 1 ‘‘OFF’’ switch to stop the No. 1 freeze cylinder beater.

18.Press SIDE 1 “BLEND ON/OFF” switch to prevent more sanitizing solution from entering the product blender tank.

19.Place waste container under No. 1 dispensing valve nozzle. Open the dispensing valve and dispense all sanitizing solution from the freeze cylinder. As sanitizing solution level lowers in the freeze cylinder, partially close the valve to avoid spurting.

20.Place waste container under the No. 1 product blender tank product sample valve. Slowly open the valve and purge remaining sanitizing solution out of the tank, then close the valve.

21.Syrup Tank System.

A.Disconnect sanitizing solution tank from No. 1 syrup system.

B.Connect syrup tank containing syrup into No. 1 syrup system.

R-404A specifications

Cornelius R-404A is a synthetic refrigerant blend widely used in various refrigeration and air conditioning applications. Composed primarily of three components—R-125 (44%), R-143a (52%), and R-134a (4%)—this blend is designed to provide effective cooling performance in both commercial and industrial environments. Its popularity can be attributed to its efficient thermodynamic properties, making it a suitable choice for low and medium temperature refrigeration systems.

One of the hallmark features of R-404A is its high energy efficiency. As a refrigerant, it offers excellent performance in heat transfer capabilities, which translates to lower energy consumption and operational costs. R-404A operates effectively within a wide range of evaporating temperatures, allowing it to serve various applications, from refrigerated display cases to cold storage facilities. The refrigerant's low glide temperature helps maintain consistent temperatures in these applications, enhancing food safety and product quality.

R-404A does not belong to the ozone-depleting substances category, making it an environmentally friendly choice. However, it is important to note that R-404A does have a significant global warming potential (GWP) of 3,922, raising concerns regarding its long-term environmental impact. As awareness of climate change increases, industries are shifting towards alternative refrigerants with lower GWPs, but R-404A remains prevalent in many existing systems.

In terms of compatibility, R-404A is non-toxic and non-flammable, making it a safe choice for use in commercial environments. Additionally, it is compatible with oils traditionally used in refrigeration systems, simplifying retrofitting processes when upgrading from other refrigerants. R-404A is also designed to work with standard refrigeration components, ensuring compatibility with existing equipment.

To maximize efficiency and performance when using R-404A, proper system design and maintenance are critical. Regular checks for leaks, appropriate charge levels, and routine maintenance can help extend the life of the system while ensuring optimal performance of R-404A as a refrigerant. As industries continue to adapt to evolving regulations and environmental concerns, the future of R-404A will likely involve the transition to lower-GWP refrigerants, but its robust features and performance continue to make it a staple in the refrigeration landscape.
