CONTROL PANEL DISPLAY MESSAGES

‘‘FILL 1’’ and ‘‘FILL 2’’ Fault Messages.

‘‘FILL 1’’ and ‘‘FILL 2’’ fault messages will appear on the message display only after the “SYRUP PRIME” switches have been pressed and the syrup systems sold-out floats have been filled with product. ‘‘FILL 1’’ and ‘‘FILL 2’’ fault messages will continue to be displayed until the “BLEND ON/OFF” switches have been pressed to fill the product blender tanks with product.

‘‘ERROR 1’’ and ‘‘ERROR 2’’ Fault Messages.

‘‘ERROR 1’’ and ‘‘ERROR 2’’ fault messages will appear on the message display only if an error within the Unit has developed interrupting normal operation. Error will have to be located and corrected, then press the ‘‘ERROR RESET’’ to restore the Unit to normal operation. ‘‘ERROR 1’’ or ‘‘ERROR 2’’ fault message will disap- pear from the display.

‘‘OFF 1’’ and ‘‘OFF 2’’ Fault Messages.

‘‘OFF 1’’ and ‘‘OFF 2’’ fault messages will appear on the message display when either freeze cylinder beater is not operating.

‘‘H2O OUT’’ Fault Message.

The Unit plain water inlet system contains a water pressure switch. An “H2O OUT” fault message will appear on the message display if the plain water source to the unit has been disrupted or if a water pressure drop should occur. The Unit will continue to operate for 1-1/2 minutes after ‘‘H2O OUT’’ fault message has appeared. If the water pressure has not been restored or the water pressure improved after 1-1/2 minutes, the Unit operation will shut down. After plain water source has been restored or the water pressure has improved, the Unit will resume it’s normal operation and the ‘‘H2O OUT’’ fault message will disappear from the message display.

‘‘CO2 OUT’’ Fault Message.

‘‘CO2 OUT’’ fault message will appear on the message display when CO2 supply to the Unit has been turned off or if the CO2 pressure drops below 50-psi. A minimum CO2 pressure of 75-psi must be available to the Unit to extinguish the ‘‘CO2 OUT’’ fault message.

‘‘SYRUP 1’’ or ‘‘SYRUP 2’’ Fault Messages.

‘‘SYRUP 1’’ or ‘‘SYRUP 2’’ fault messages will appear on the message display if the syrup supply is not con- nected to the Unit syrup system or if the syrup supply is exhausted. The Unit syrup systems syrup float switches must be filled with syrup to extinguish the ‘‘SYRUP 1’’ or ‘‘SYRUP 2’’ fault messages.

‘‘DEFROST 1’’ or ‘‘DEFROST 2’’ Display Messages.

‘‘DEFROST 1’’ or ‘‘DEFROST 2’’ display messages will appear on the message display if either freeze cylinder is in the defrost mode. ‘‘DEFROST 1’’ or ‘‘DEFROST 2’’ messages will remain on during the defrost cycle and will disappear when the cycle has ended.

‘‘POINT OF SALE’’ Display Messages.

Three ‘‘POINT OF SALE‘’ display messages are available to choose from and may be programmed into the Unit to appear on the message display. The “POINT OF SALE” display messages should be programmed into the Unit electronics by a qualified Service Person.

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.
