3.Unfasten safety chain and remove empty CO2 cylinder.

4.Position full CO2 cylinder and secure with safety chain.

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

5.Make sure gasket is in place inside the CO2 regulator coupling nut, then install regulator on CO2 cylinder.

6.Open (counterclockwise) CO2 cylinder valve slightly to allow the lines to slowly fill with gas, then open the valve fully to back-seat the valve. (Back-seating the valve prevents leakage around the valve shaft).

7.Check CO2 connections for leaks. Tighten loose connections.

CLEANING AND SANITIZING

DAILY CLEANING OF UNIT

Daily, or more often if necessary, wash all external surfaces of the Unit with a mild soap solution. Rinse with clean water, then wipe the Unit dry with a clean soft cloth. DO NOT USE ABRASIVE CLEANERS. Remove and wash the drip tray in a mild soap solution, rinse with clean water, then install drip tray on the Unit.

SANITIZING SYRUP SYSTEMS

NOTE: The Unit should be sanitized every 90 days by a qualified Service Person following the Sanitizer Manufacturer’s recommendation. Use Chlor-Tergent (Oakite Products, Inc.) or equivalent sanitizer.

The Unit should be sanitized every 90 days following the parent company requirements and the sanitizer manufacturer’s recommendations. One or both of the syrup systems may be sanitized at one time for routine 90 days sanitizing requirements. The following sanitizing instructions use No.1 syrup system as an example. No. 2 syrup systems sanitizing instructions are identical to No. 1 syrup system with the exception of using applicable system switches. Proceed as follows:

1.Press SIDE 2 ‘‘OFF’’ switch to stop beater motor and refrigeration in No. 2 freeze cylinder, which is not to be defrosted. ‘‘OFF 2’’ fault message will appear on message display.

2.Press ‘‘MANUAL DEFROST’’ switch to start defrost cycle on No. 1 freeze cylinder. ‘‘DEFROST 1’’ mes- sage will appear on message display as long as defrost cycle is in progress.

3.Immediately press SIDE 2 ‘‘BLEND ON/OFF’’ switch to restart the beater in No. 2 freeze cylinder. Refrig- eration in No. 2 cylinder will not be operating.

4.Remove right-hand side panel as instructed for access to No. 2 product blender tank product shutoff valve.

5.Close No. 2 product blender tank product shutoff valve to prevent product bleeding back into No. 1 product blender tank during sanitizing procedure.

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

7.Place waste container under No. 1 cylinder dispensing valve nozzle. Open dispensing valve and dispense all product from the freeze cylinder and the product blender tank. As product level lowers in the freeze cyl- inder, partially close the valve to avoid spurting.

8.Remove Unit front lower access panel as instructed for access to No. 1 product blender tank product sam- ple valve.

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

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.
