WARNING: Disconnect electrical power to the Unit to prevent personal injury before attempting any internal maintenance. Only qualified personnel should service internal components or electrical wiring.

CONTROL PANEL (KEYPAD) SECURITY

The optional control panel (keypad) security (options DIP6 switch) may be programmed into the Unit to enable (activate) or disable (de-activate) the control panel security. When the control panel security is enabled, any control panel switch can be pushed and held for 5-seconds to override the control panel security. An audible beep will be heard when the switch is first pushed, then another beep will be heard when the security override has taken place and the switch may be released. Control panel security will be re-established 90-seconds after switch pushing activity has ceased. Control panel (keypad) security should be programmed into the Unit elec- tronics by a qualified Service Person.

Note: When in programming menu, the control panel security will not re-establish until after exiting programming menu.

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.
