Bag-in-Box Syrup System.

A.Remove end of No. 1 syrup pump syrup inlet line from pail of sanitizing solution.

B.Remove empty bag-in-box connector from No. 1 syrup pump syrup inlet line.

C.Connect No. 1 syrup pump syrup inlet line to bag-in-box containing syrup.

22.Press SIDE 1 “SYRUP PRIME” switch to fill No. 1 syrup system syrup float switch with syrup.

23.Press SIDE 1 ‘‘BLEND ON/OFF’’ switch to fill No. 1 product blender tank with product. Carbonator water pump will start and begin pumping carbonated water into the product blender tank along with syrup to make product.

WARNING: Flush residual sanitizing solution from the syrup system as instructed. Residual sanitizing solution left in the syrup system could create a health hazard.

24.After carbonator water pump cycles off, completely fill No.1 freeze cylinder with product by repeatedly pull- ing and releasing the faceplate relief valve and until product comes out of the relief valve port. Open the dispensing valve until product flows from the valve, then close the valve. Open No. 1 system product sam- ple valve until product flows from the valve, then close the valve.

25.Press SIDE 1 “MOTOR” switch to start No. 1 freeze cylinder beater. Allow beater to operate for 5-minutes, then press SIDE 1 “OFF” switch to stop the beater.

26.Syrup Tank System.

A.Disconnect syrup tank containing syrup from No. 1 syrup system.

B.Connect empty syrup tank into 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.Install connector from empty bag-in-box on No. 1 syrup pump syrup inlet line.

27.Hold waste container under the dispensing valve and dispense until all product has been dispensed from the freeze cylinder. As product level lowers in the freeze cylinder, partially close the valve to avoid spurting.

28.Place waste container under No.1 system product sample valve. Slowly open the valve and purge remain- ing product out of the product blender tank, then close the valve.

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

29.Syrup Tank System.

A.Disconnect empty syrup tank from No. 1 syrup system.

B.Connect syrup tank containing syrup into No. 1 syrup system. Bag-in-Box Syrup System.

A.Remove empty bag-in-box connector from No. 1 syrup pump syrup inlet line.

B.Connect No. 1 syrup pump syrup inlet line to bag-in-box containing syrup.

30.Press SIDE 1 “SYRUP PRIME” switch to fill No. 1 syrup system syrup float switch with syrup.

31.Press SIDE 1 ‘‘BLEND ON/OFF’’ switch to fill No. 1 product blender tank with product. Carbonator water pump will start and begin pumping carbonated water into the product blender tank along with syrup to make product.

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.
